‘Pieta’(1980) by Se Choong Kim required scientific analysis and conservation treatment due to long outdoor exhibitions and paint on surface of bronze sculpture. However, there was a concern that the originality of artwork and ‘moral rights of the artist(the right of integrity)’ could be violated by including conservation treatment methods that were inevitably irreversible, such as removing the old layer and re-patination. Accordingly, the brown color that was mainly used during the artist’s lifetime, was selected as the patination color through collaboration with various stakeholders. As a result of analyzing the making technique of ‘Pieta’, it was found that it was cast in Cu-Zn-Sn-Pb quaternary art bronze. The material, methods, and environment at the time of making artwork were confirmed by comparing the result of scientific analysis of welding, repair, and defects with inerviews with casting engineers. The paint painted on the surface of the bronze sculpture was confirmed as painted twice with metalic paint mixed with polystyrene and copper powder and graphite-based paint. Laser cleaning was applied after a preliminary experiments to stably remove paint, and 95% of the paint layer area was uniformly removed as a result of comparing and analyzing the volume before and after removal through 3D scanning. Brown patina was applied through patination then wax coating to finish.

ABSTRACTArtemisinin (ART)-based combination therapy (ACT) is used as the first-line treatment of uncomplicated falciparum malaria worldwide. However, despite high potency and rapid action, there is a high rate of recrudescence associated with ART monotherapy or ACT long before the recent emergence of ART resistance. ART-induced ring-stage dormancy and recovery have been implicated as possible causes of recrudescence; however, little is known about the characteristics of dormant parasites, including whether dormant parasites are metabolically active. We investigated the transcription of 12 genes encoding key enzymes in various metabolic pathways inP. falciparumduring dihydroartemisinin (DHA)-induced dormancy and recovery. Transcription analysis showed an immediate downregulation for 10 genes following exposure to DHA but continued transcription of 2 genes encoding apicoplast and mitochondrial proteins. Transcription of several additional genes encoding apicoplast and mitochondrial proteins, particularly of genes encoding enzymes in pyruvate metabolism and fatty acid synthesis pathways, was also maintained. Additions of inhibitors for biotin acetyl-coenzyme A (CoA) carboxylase and enoyl-acyl carrier reductase of the fatty acid synthesis pathways delayed the recovery of dormant parasites by 6 and 4 days, respectively, following DHA treatment. Our results demonstrate that most metabolic pathways are downregulated in DHA-induced dormant parasites. In contrast, fatty acid and pyruvate metabolic pathways remain active. These findings highlight new targets to interrupt recovery of parasites from ART-induced dormancy and to reduce the rate of recrudescence following ART treatment.

Introduction Integrase strand transfer inhibitors (INSTI) are one of the most prescribed drug classes for the treatment of HIV infection worldwide. Emtricitabine/Tenofovir Alafenamide/ Bictegravir (FTC/TAF/BIC) has been evaluated in randomized clinical trials; few studies have verified tolerability and safety in clinical practice. Our aim was to investigate the metabolic and hepatic safety in a real-life setting of FTC/TAF/BIC. Materials and methods Consecutive people living with HIV infection (PLWH) enrolled in the SCOLTA project, switching to or initiating their first antiretroviral treatment with FTC/TAF/BIC were included. PLWH with HBV co-infection were excluded. Metabolic and hepatic variables were collected at T0 and T1, were defined as baseline and 6-month follow-up respectively, and their modifications were analysed using the paired t-test and the analysis of variance. Results Five hundred and thirty-nine PLWH with at least one follow-up visit were included in the analysis. Mean age was 48 years (±12.1), 74% were male, 16.1% were naïve to antiretrovirals (ART). At T1, ART-experienced PLWH showed a significant reduction of total cholesterol (TC) and triglycerides, and a slight increase in blood glucose (BG) and ALT. On the contrary, in ART-naïve PLWH blood lipids significantly increased, although with an unaffected TC/high density lipoprotein (HDL)-c ratio, while alanine aminotransferase (ALT) decreased significantly, mainly in those with altered baseline level. The treatment interruptions were 45 (8.4%) over the whole observation period, 13 (2.4%) due to AEs. The most frequent AEs were related to the central nervous system (6 events of depression, insomnia, headache, agitation) and 3 PLWH discontinued the regimen because of grade 1–2 weight gain. Conclusions In ART-experienced PLWH switching to FTC/TAF/BIC a significant improvement of lipid profile occurred but with significant BG and ALT variation without clinical relevance. In ART-naïve PLWH, blood lipids increased even though lipid profile did not worsen, and a trend towards normalization of liver enzymes was suggested. FTC/TAF/BIC is well tolerated in the real life setting.

Introduction: Metabolic syndrome (MetS) and Non-alcoholic fatty liver disease (NAFLD) are two major causes of morbidity in chronic HIV infected patients on antiretroviral therapy (ART). This study was done on HIV infected individuals by comparing ART naive patients with patients on different ART regimens and evaluating the effect of ART on Metabolic syndrome and NAFLD.Method: It was a cross-sectional observational study done on 120 HIV infected individuals in a tertiary care centre in New Delhi. All cases with hypertension, diabetes, chronic kidney or liver disease, thyroid disorders or on any drugs except ART were excluded. The risk markers for metabolic syndrome were assessed and compared within groups on different ART regimens.Results: Metabolic syndrome and NAFLD were found to be significantly more in cases on ART as compared to ART naïve cases. Metabolic syndrome was found to be associated with type of ART protease inhibitors (ATV/r)> nonucleoside reverse transcriptase inhibitors (NNRTI) > no ART] and low CD4 cell counts (p=0.01). In those patients who were on ART, these parameters were found to be more in those on second line ART [i.e., protease inhibitor (PI)(ATV/r) based regimens] as compared to those on first line ART, [i.e., nonnucleoside reverse transcriptase inhibitors (NNRTI) based regimen]. 15% of cases on 2nd line ART (group C) had MetS as compared to 12.5% in those on 1st line ART (group B) and nil in ART naïve cases (group A). One third (34%) of all 120 cases were found to have NAFLD. A significantly higher number of cases (45%) in group C had NAFLD as compared to 32.5% in group B and 25% in group A respectively. Insulin resistance and metabolic risk markers were also significantly higher in cases on ART as compared to ART naïve.Conclusions: In HIV patients, the use of antiretroviral therapy (ART) is linked to an increase in the prevalence of metabolic risk factors, including insulin resistance, lipoatrophy and dystrophy, dyslipidaemia, and abnormalities of fat distribution. Although care of Opportunistic infections and recently CVD has received a lot of attention, it is equally important to address the metabolic abnormalities such as metabolic syndrome and NAFLD brought on by ART.

PONTIFÍCIA UNIVERSIDADE CATÓLICA DO RIO DE JANEIRO
A metalurgia é a ciência que estuda os diversos meios para a transformação dos metais em materiais úteis à sociedade. A metalurgia do ferro representa a maior fatia da aplicação dos metais. Por ser tão representativa é chamada de Siderurgia. Dentre as diversas rotas para a transformação do ferro em aço, as usinas semi-integradas apresentam um forte apelo ecológico, pois utilizam a sucata, oriunda da reciclagem de ferro, e o ferro gusa como matérias-primas para a fusão no Forno Elétrico a Arco. Naturalmente, em todo processo industrial há a geração de resíduos e, neste caso, o principal é a escória, composta de óxidos formados e adicionados ao longo da fusão. Seus principais constituintes são: CaO, SiO2, FeO, MnO, MgO, Al2O3 e P2O5. No entanto, ainda há a presença de Ferro Metálico, um fato indesejável, pois atua negativamente no rendimento metálico e, consequentemente, aumenta o custo do aço. Toda escória gerada é beneficiada com o intuito de recuperar a parte metálica. Este material beneficiado retorna para as usinas como sucata metálica, contendo teores definidos de ferro metálico. O teor de ferro presente na sucata recuperada é avaliado pelas empresas processadoras de escória de maneira indireta por um ensaio de densidade específica. Havia dúvidas se a sucata recuperada da escória do forno apresentava teores de ferro que justificasse seu emprego como matéria-prima ferrosa. Assim sendo, foi proposta uma rota de processamento capaz de mensurar o teor de ferro presente e permitir a comparação com os teores obtidos com o ensaio de densidade. Os resultados mostram que i) é possível calcular o impacto no rendimento, ii) que as sucatas recuperadas apresentam valores inferiores ao esperado, iii) que a equação de densidade superestima o teor de ferro e iv) que modificações propostas nos coeficientes da equação vigente melhoram seu grau de assertividade. Estes resultados foram comprovados em 3 plantas siderúrgicas.
Metallurgy is the science that studies the various processes for the transformation of metals into society useful materials. The iron metallurgy represents the largest body of the metals application, hence it is called Steel industry. Among the various routes for the transformation of iron into steel, semiintegrated plants have a strong ecological appeal due to their extensive use of scrap, derived from the recycling of iron, and pig iron as raw materials for the Electric Arc Furnace. Of course, industrial processes generate waste. The major waste of the Electric Arc Furnace is the slag, a mixture of oxides produced during the process, containing CaO, SiO2, FeO, MnO, MgO, Al2O3 e P2O5. However, there is also the presence of metallic iron, a fact undesirable, because it acts negatively on the metallic yield and therefore increases the cost of steel. All slag generated is processed in order to recover the metallic iron. The slag beneficiation returns to the mills a material containing defined levels of iron. The content of recovered iron is assessed by slag processing companies indirectly by a specific gravity test. There have been doubts whether the recovered scrap iron content justify its use as raw ferrous materials. Therefore, it is proposed a processing route capable of measuring the amount of iron present in the recovered scrap. The measured iron content is also compared with the levels obtained from the test density. The results show that i) it is possible to calculate the impact on iron yield, ii) the recovered iron content is lower than expected, iii) the density equation overestimates the amount of iron and iv) a correction is proposed to improve the assertiveness of the density equation. Three steel plants confirmed the results from this research.

In this thesis, geometry is used as a basis for conducting experiments aimed at growing and arranging inorganic minerals on curved interfaces. Mineralisation is directed using crystalline and liquid-crystalline metallic soaps and surfactant/water systems as templates.¶ A review of the history, syntheses, structure and liquid crystallinity of metallic soaps and other amphiphiles is presented as a foundation to understanding the interfacial architectures in mesostructured template systems in general.¶ In this study, a range of metallic soaps of varying chain length and cation type are synthesised and characterised to find potentially useful templates for mineral growth. These include alkaline-earth, transition metal, heavy metal and lanthanide soaps. These are systematically characterised using a variety of analytical techniques, including chemical analyses, x-ray diffraction (XRD) infrared spectroscopy (IR) and differential scanning calorimetry (DSC). Their molecular and crystal structures are studied using transmission electron microscopy (TEM), cryo-TEM, electron diffraction (ED), electron paramagnetic spin resonance (EPR), absorption spectroscopy (UV-VIS), high resolution laser spectroscopy, atomic force microscopy (AFM), nuclear magnetic resonance spectroscopy, scanning electron microscopy (SEM), electron dispersive x-ray analysis (EDXA), thermal gravimetric analysis (TGA) and magnetic measurements. Models for the molecular and crystal structures of metallic soaps are proposed. The soaps are predominantly lamellar crystalline or liquid crystalline lamellar rotor phases with tilted and/or untilted molecular constituents. These display evidence of varying degrees of headgroup organisation, including superstructuring and polymerisation. A single crystal structure is presented for a complex of pyridine with cobalt soap. Simple models for their structure are discussed in terms of their swelling properties in water and oils. Experiments are also presented to demonstrate the sorbent properties of aluminium soaps on oil spills.¶ The thermotropic liquid crystallinity of alkaline earth, transition metal, heavy metal and lanthanide soaps is investigated in detail. This is done to assess their suitability as templates, and to document their novel thermotropic behaviour, particularly the relatively unknown lanthanide soaps. Liquid crystalline behaviours are studied using high-temperature XRD (HTXRD), hot-stage optical microscopy and DSC. Models for a liquid crystalline phase progression from crystals to anisotropic liquids are discussed in terms of theories of self-assembly and interfacial curvature. The terminology required for this is drawn from various nomenclature systems for amphiphilic crystals and liquid crystals. General agreement with previous studies is reported for known soaps, while liquid crystallinity is demonstrated in the lanthanide and some non-lanthanide soaps for the first time. A general phase progression of crystalline lamellar through liquid crystalline lamellar to non-lamellar liquid crystalline is discussed in terms of models concerned with the molecular and crystal structures of the soaps and their phase transitions via headgroup and chain re-arrangements.¶ Experiments aimed at guiding growth of metal sulfides using metallic soaps as templates are described, and a model for this growth is discussed. Metal sulfides have been successfully grown by reacting crystalline and liquid crystalline transition metal and heavy metal soaps with H2S gas at room temperature and at elevated temperature. These have been characterised using XRD, TEM, ED and IR. Sulfide growth is demonstrated to be restricted and guided by the reacting soap template architecture. Zinc, cadmium, indium and lead soaps formed confined nanoparticles within the matrix of their reacting soap template. In contrast, curved and flat sheet-like structures, some resembling sponges were found in the products of sulfided iron, cobalt, nickel, copper, tin and bismuth soaps. A model to explain this behaviour is developed in terms of the crystal and liquid crystal structures of the soaps and the crystal structures of the metal sulfide particles.¶ Liquid crystalline iron soaps have been subjected to controlled thermal degradation yielding magnetic iron oxide nanoparticles. Some XRD and TEM evidence has been found for formation of magnetic mesostructures in heat-treated iron soaps. Models for the molecular and liquid crystalline structure of iron soaps, their thermotropic phase progression and eventual conversion to these magnetic products are discussed. Systematic syntheses of mesoporous silicates from sheeted clays are discussed.¶The templates that have been used are cationic surfactants and small, organic molecular salts. Experiments are reported where a cooperative self-assembly of surfactant/water/kanemite plus or minus salt and oils yields 'folded sheet materials' (FSM'S). Templating of kanemite has also been achieved using cobalt cage surfactants. A theoretical prediction of the specific surface areas and specific volumes of homologous sets of FSM's gave excellent agreement with measured values. The geometry and topology of the mesostructures are discussed. A theoretical model is also discussed regarding the curvature found in the sheets of natural clays , and results of templating clays and silica using metallic soaps are presented. Experiments and a model for low temperature nucleation and growth of microporous silicalite-1 are described in terms of silica templating by water clathrates.¶ Finally, the problem of finding minimal surface descriptions of crystal networks is addressed. Combinatoric methods are used to disprove the existence of possible embeddings of type I and II clathrate networks in non-self intersecting periodic minimal surfaces. The crystal network of the clathrate silicate, melanophlogite is successfully embedded in the WI-10 self-intersecting surface. Details of a previously unreported, genus-25 periodic surface with symmetry Im3m are discussed.

Nanoindentation has brought in many features of research over the past decade. This novel technique is capable of producing insights into the small ranges of deformation. This special point has brought a lot of focus in understanding the deformation behavior under the indenter. Nickel, iron, tungsten and copper-niobium alloy system were considered for a surface deformation study. All the samples exhibited a spectrum of residual deformation. The change in behavior with indentation and the materials responses to deformation at low and high loads is addressed in this study. A study on indenter geometry, which has a huge influence on the contact area and subsequently the hardness and modulus value, has been attempted. Deformation mechanisms that govern the plastic flow in materials at low loads of indentation and their sensitivity to the rate of strain imparted has been studied. A transition to elastic, plastic kind of a tendency to an elasto-plastic tendency was seen with an increase in the strain rate. All samples exhibited the same kind of behavior and a special focus is drawn in comparing the FCC nickel with BCC tungsten and iron where the persistence of the elastic, plastic response was addressed. However there is no absolute reason for the inconsistencies in the mechanical properties observed in preliminary testing, more insights can be provided with advanced microscopy techniques where the study can be focused more to understand the deformation behavior under the indenter. These experiments demonstrate that there is a wealth of information in the initial stages of indentation and has led to much more insights into the incipient stages of plasticity.

Bulk metallic glasses and multi-principal element alloys represent relatively new classes of multi-component engineering materials designed for satisfying multiple functionalities simultaneously. Correlating the microstructure with mechanical behavior (at the microstructural length-scales) in these materials is key to understanding their performance. In this study, the structure evolution and nano-mechanical behavior of these two classes of materials was investigated with the objective of fundamental scientific understanding of their properties. The structure evolution, high temperature nano-mechanical behavior, and creep of two Zr-based alloys was studied: Zr41.2Ti13.8Cu12.5Ni10.0Be22 (Vitreloy1) and Zr52.5Ti5Cu17.9Ni14.6All0 (Vitreloy105). Devitrification was found to proceed via the formation of a metastable icosahedral phase with five-fold symmetry. The deformation mechanism changes from inhomogeneous or serrated flow to homogenous flow near 0.9Tg, where Tg is the glass transition temperature. The creep activation energy for Vitreloy1 and Vitreloy105 were 144 kJ/mol and 125 kJ/mol, respectively in the range of room temperature to 0.75Tg. The apparent activation energy increased drastically to 192 kJ/mol for Vitreloy1 and 215 kJ/mol for Vitreloy105 in the range of 0.9Tg to Tg, indicating a change in creep mechanism. Structure evolution in catalytic amorphous alloys, Pt57.5Cu14.7Ni5.3P22.5 and Pd43Cu27Ni10P20, was studied using 3D atom probe tomography and elemental segregation between different phases and the interface characteristics were identified. The structure evolution of three multi-principal element alloys were investigated namely CoCrNi, CoCrFeMnNi, and Al0.1CoCrFeNi. All three alloys formed a single-phase FCC structure in as-cast, cold worked and recrystallized state. No secondary phases precipitated after prolonged heat treatment or mechanical working. The multi-principal element alloys showed less strain gradient plasticity compared to pure metals like Ni during nano-indentation. This was attributed to the highly distorted lattice which resulted in lesser density of geometrically necessary dislocations (GNDs). Dislocation nucleation was studied by low load indentation along with the evaluation of activation volume and activation energy. This was done using a statistical approach of analyzing the "pop-in" load marking incipient plasticity. The strain rate sensitivity of nanocrystalline Al0.1CoCrFeNi alloy was determined by in situ compression of nano-pillars in a Pico-indenter. The nanocrystalline alloy demonstrated a yield strength of ~ 2.4 GPa, ten times greater than its coarse grained counterpart. The nanocrystalline alloy exhibited high strain rate sensitivity index of 0.043 and activation volume of 5b3 suggesting grain boundary dislocation nucleation.

Lack of crystalline order and microstructural features such as grain/grain-boundary in metallic glasses results in a suite of remarkable attributes including very high strength, close to theoretical elasticity, high corrosion and wear resistance, and soft magnetic properties. By altering the morphology and tuning of composition, MGs may be transformed into high-performance catalytic materials. In this study, the catalytic properties of metallic glass powders were demonstrated in dissociating toxic organic chemicals such as AZO dye. BMG powders showed superior performance compared to state of the art crystalline iron because of their high catalytic activity, durability, and reusability. To enhance the catalytic properties, high energy mechanical milling was performed to increase the surface area and defect density. Iron-based bulk metallic glass (BMG) of composition Fe48Cr15Mo14Y2C15B6 was used because of its low cost and ability to make large surface area by high energy ball milling. AZO dye was degraded in less than 20 minutes for the 9 hours milled Fe-BMG. However, subsequent increase in ball milling time resulted in devitrification and loss of catalytic activity as measured using UV-Visible spectroscopy. Aluminum-based bulk metallic glass (Al-BMG) powder of composition Al82Fe3Ni8Y7 was synthesized by arc-melting the constituent elements followed by gas-atomization. The particle size and morphology were similar to Fe-BMG with a fully amorphous structure. A small percentage of transition metal constituents (Fe and Ni) in a mostly aluminum alloy showed high catalytic activity, with no toxic by-products and no change in surface characteristics. Al-alloy particles, being light-weight, were easily dispersed in aqueous medium and accelerated the redox reactions. The mechanism of dye dissociation was studied using Raman and Infrared (IR) spectroscopy. Breaking of -C-H- and - C-N- bonds of AZO dye was found to be the primary mechanism. Mechanical behavior of individual BMG particles was evaluated by in situ pico-indentation in a scanning electron microscope (SEM) to understand the fracture mechanisms. Catastrophic shear banding was found to be the primary fracture mode, which supported the observation of flake formation during high energy ball milling.

Novel net shaping technique Laser Engineered Net shaping™ (LENS) laser based manufacturing solution (Sandia Corp., Albuquerque, NM); Laser can be used to deposit orthopedic implant alloys. Ti-35Nb-7Zr-5Ta (TNZT) alloy system was deposited using LENS. The corrosion resistance being an important prerequisite was tested electrochemically and was found that the LENS deposited TNZT was better than conventionally used Ti-6Al-4V in 0.1N HCl and a simulated body solution. A detailed analysis of the corrosion product exhibited the presence of complex oxides which are responsible for the excellent corrosion resistance. In addition, the in vitro tests done on LENS deposited TNZT showed that they have excellent biocompatibility. In order to improve the wear resistance of the TNZT system boride reinforcements were carried out in the matrix using LENS processing. The tribological response of the metal matrix composites was studied under different conditions and compared with Ti-6Al-4V. Usage of Si3N4 balls as a counterpart in the wear studies showed that there is boride pullout resulting in third body abrasive wear with higher coefficient of friction (COF). Using 440C stainless steel balls drastically improved the COF of as deposited TNZT+2B and seemed to eliminate the effect of “three body abrasive wear,” and also exhibited superior wear resistance than Ti-6Al-4V.

Through the lens of underground heavy metal, this thesis explores the importance of live music and the ways in which music worlds transform, decline and remain resilient. In a departure from traditional academic studies of heavy metal, which focus on notions of youth, rebellion, gender and subversive themes, (Weinstein, 1999; Krenske and McKay, 2000; Bennett, 2001), this thesis takes a novel approach in exploring the active nature of this music world. As artists face problems with digital distribution and the related decline of record sales, live music was expected to flourish, as artists seek to compensate for lost recording revenue through live shows. However, this world is not as straightforward as it might appear; arguably it is an industry which is becoming increasingly volatile. As grass-roots venues close and touring costs increase for artists, underground live music faces a particularly tough struggle. Therefore, in contributing to the growing body of literature on 'Art Worlds', (Becker, 1982), this thesis develops an understanding of the ways in which venues, promoters and audiences attempt to sustain this music world. Through surveying attendance at live events and interviewing active participants, it is argued that whilst this music world suggests elements of decline it also shows perseverance. Through the development of translocal networks and maintenance of community, these participants pool resources in order to facilitate live events; even in the face of tremendous struggle. In doing so, this thesis makes a unique contribution to academic understandings of underground metal, capturing this music world at a particularly tumultuous time.

Annotation:
Bulk metallic glasses (BMGs) have received significant research interest due to their completely amorphous structure which results in unique structural and functional properties. Absence of grain boundaries and secondary phases in BMGs results in high corrosion resistance in many different environments. Understanding and tailoring the corrosion behavior can be significant for various structural applications in bulk form as well as coatings. In this study, the corrosion behavior of several Zr-based and Fe-Co based BMGs was evaluated to understand the effect of chemistry as well as quenched in free volume on corrosion behavior and mechanisms. Presence of Nb in Zr-based alloys was found to significantly improve corrosion resistance due to the formation of a stable passive oxide. Relaxed glasses showed lower rates compared to the as-cast alloys. This was attributed to lowering of chemical potential from the reduced fraction of free volume. Potentiodynamic polarization and Electrochemical Impedance Spectroscopy (EIS) techniques helped in quantifying the corrosion rate and polarization resistance. The effect of alloy composition was quantified by extensive surface analysis using Raman spectroscopy, energy dispersive x-ray spectroscopy and auger spectroscopy. Pitting intensity was higher in the as-cast glasses than the relaxed glasses. The electrochemical behavior of a Zr-Ti-Cu-Ni-Be bulk metallic glass subjected to high strain processing was studied. High strain processing caused shear band formation and an increase in the free volume. Potentiodynamic polarization and EIS showed a strong correlation between the enthalpy of structural relaxation and corrosion rate and polarization resistance. Pitting was observed to preferentially occur on shear bands in the processed samples, while it was stochastic in unprocessed glass. The corrosion analysis of Co-Fe glasses showed an increase in corrosion current density when Fe content was increased from 0 to 7 at%. The corrosion resistance improved when Fe content was further increased to 15 at%. Similar trend was seen in EIS studies. The improved corrosion resistance at 15 at% Fe can be attributed to the large supercooled region that facilitates the formation of completely amorphous alloy, in contrast to lower Fe containing alloys, where short range ordering may deteriorate the corrosion resistance. Porous metallic glass structure was developed by electrochemical dealloying via cyclic voltammetry. Mechanical properties and changes in electrical conductivity were measured as a function of depth from surface by nano-indentation and nano electrical contact resistance technique. The nanoporous layer was found have hardness of 0.41 GPa and elastic modulus of nearly 22 GPa. The resistivity of the nanoporous layer continuously decreased when moving towards the substrate as the indentation depth increased which is attributed to the gradient in pore size.

AbstractWire arc additive manufacturing allows the production of metallic parts by depositing beads of weld metal using arc-welding technologies. This low-cost additive manufacturing technology has the ability to manufacture large-scale parts at a high deposition rate. However, the quality of the obtained parts is greatly affected by the various thermal phenomena present during the manufacturing process. Numerical simulation remains an effective tool for studying such phenomena. In this work, a new finite element technique is proposed in order to model metal deposition in WAAM process. This technique allows to gradually construct the mesh representing the deposited regions along the deposition path. The heat source model proposed by Goldak is adapted and combined with the proposed metal deposition technique taking into account the energy distribution between filler material and the molten pool. The effectiveness of the proposed method is validated by series of experiments, of which an example is detailed in this paper.

The existence and availability of metals is taken for granted by most people. However, these perceptions will be challenged as global metal demand increases due to economic development, and supplies are threatened by dwindling geological reserves and shifting geopolitics. Alternative sources and methods of supply must be developed if we are to meet anticipated needs for metals, including those required for the transition to renewable energy systems. The ideal goal is a circular economy, where recycling and reuse of metal-containing products keep these resources available to the economy as long as possible. At the same time, innovation within the existing global metal supply system can provide new access to metal sources and opportunities for improved recovery of metals along the supply chain. The key is to open new points of entry into the metal supply system, identify and remove barriers, introduce necessary technologies, and organize more efficient business models. This includes the targeting of smaller-scale deposits and the more efficient recovery of metals from waste material at various points along the supply chain. If society were more engaged in such developments, metals could be more efficiently supplied with significant economic benefits to a larger number of individuals.

AbstractFirst widely used ureteral stents were polymeric and first documented metallic stent placed in ureter was vascular permanent stent in patient with malignant obstruction. Due to high complication rates with off label bare metal stents and covered metal stents development of purpose-based urological metallic stents was started. They are nowadays usually exploited when longer indwelling times are envisioned due to benign conditions, malignant obstruction or post-radiotherapy. In our analysis we have witnessed high risk of complication—68% per patient and 50% per stent.Further research in form of multi-institutional prospective RCT in order to obtain better understanding of complications is needed which in turn can drive further development of stent materials, coatings and designs ultimately giving our patients better QoL.

Abstract. In previous studies, composite metal foams (CMF) have shown exemplary mechanical performance under impact which has made them prime candidates for protection of transported passengers and cargo. [1] Materials utilized in such applications often require joining to form structures and geometries that are far more complex or impossible to produce in an as-manufactured state. Welding methods are popular in the joining of metals with solid-state welding processes such as induction welding being of particular interest in the studies to be discussed. In this study, various thicknesses of 316L stainless steel CMF are manufactured through powder metallurgy technique and welded using Induction Welding. The mechanical properties of the weldments were studied through uniaxial tensile tests while microstructural characterization of the weldment within the joint interface and heat-affected zone (HAZ) are evaluated using scanning electron microscopy. The combination of these evaluations grant insight on the effects of various weld parameters (e.g., welding temperature, workpiece thickness, flux, and welding environment) as well as the suitability and restrictions of induction welding in the joining of 316L Stainless Steel CMF.

Abstract. The growing market of power electronics in the mobility sector leads to an increasing demand for cooling systems. In the project this need to improve performance is to be met by adapting the cooling structure. Depending on the intended application of cooling systems - automotive, railway and aerospace - different requirements are defined for the cooling process resulting in varying conditions for the design. So metallic foam structures are under investigation because of their high inner surface. Two different process lines are most suitable for the aimed application. The production and optimization of galvanized foams seems to be the most lucrative for a low-cost product, while 3D printing is currently only worthwhile for special applications such as aerospace. As a potentially more cost-effective process, which is already being used for small series, investment casting structures are being investigated as an alternative. Depending on the production process chosen, corresponding requirements for structure creation suitable for production apply. Corresponding process adaptations are also taken into consideration. The first optimization step is an analysis of the conventional open cellular metal foam structures using CT. The results of the CT evaluation, together with the empirical data for fluid mechanical and thermal characteristics, are the basis for a later replacement model of the CFD simulation. Besides the Kelvin cell, which is a good geometrical substitute for the conventional structures that copy the Polyurethan master pattern, other cell types are also considered. Alternatively, structures based on mathematical cells e.g. Schwarz P/D, offer the possibility of separating two media to create cross-flow or counter-flow heat exchangers. Regardless of the chosen system, the main task of the investigation is to find an optimum of the relation between pressure drop and heat transfer performance for the corresponding system and to design the cell arrangement in a way that is suitable for manufacturing. This justifies, among other things, the investigation of a minimal surface structure, which at first seems contradictory. Considering the manufacturing process to be defined beforehand, requirements such as self-supporting design (additive process) and free accessibility (electroplating) also play an important role in the structure development. Thus, the goal is still to optimize the cell and web geometry accordingly.

Abstract. There are many potential applications for lightweight open-cellular metal structures, such as energy absorption, filtering, or thermal management. Such metallic open-cellular structures are often produced by additive manufacturing. Another option is the use of investment casting, for example by using open polymer foams as a template. By designing structures via Computer-Aided-Design (CAD), these can be used directly for additive manufacturing, either directly in metal or in wax as a template for casting. In this way the structure can be adapted very well to the needs, possible applications are shown in [1]. Using polymeric templates reduces the adaptability of the structure immensely. To use the full potential, it is necessary to develop the structure according to its future purpose. The 'ProZell' project is developing the basis for realizing such structures in high-manganese steels by investment casting using the lost wax process.

Abstract. Several studies in the literature have been devoted to the permeability prediction of metal foams, including that involving the Representative Unit Cell (RUC) model. The RUC modelling approach is an attractive modelling method due to the simple rectangular geometry, as well as its satisfying performance in comparison to other models and experimental data as proven elsewhere in the literature for porous media. The subject of compression of metal foams has been addressed elsewhere in the literature, but this study is the first to involve an all-inclusive analytical model where both streamwise and transverse compression are accounted for. The Darcy and Forchheimer permeability coefficients of the compressed foam (or three-strut) RUC model are presented. Furthermore, a geometric approach requiring measured geometric parameters and a combined geometric-kinetic approach involving measured permeability coefficients are included for determining the specific surface area. Geometric parameters required to determine the permeability and specific surface area predictions using the compressed foam RUC model include the uncompressed porosity, pore dimension and strut diameter, as well as the compression factor. The model is evaluated through comparison with available experimental data and empirical models obtained from the literature for compressed metal foams. The compressed RUC model predictions produce expected tendencies of geometrical parameters of metal foams under compression and the comparison with experimental data reveal satisfactory results.

Abstract. Metal foams are cellular solids with high stiffness, high strength and superior energy absorption capacity. In liquid metallurgy, foams are processed by foaming the molten metal with the addition of foaming agents and stabilized by the presence of particles which also strengthen the cell walls. An analysis of the deformation behaviour of foams in the presence of these stabilizing particles is essential to the mechanism of energy absorption. In the present study, the effect of the particle distribution on the deformation behaviour of the closed-cell aluminium foams was investigated using Finite Element Analysis (FEA) in Abaqus© software. The experimental data were used to model the distribution of particles in the matrix and the foam model. The simulation results were validated with the experimental results. The uniform distribution of particles in the matrix resulted in lower stress concentration and enhanced the mechanical performance of composite material and the metal foam.

Abstract. According to the US Department of Transportation (DOT), there are millions of liters of hazardous materials (HAZMATS) transported each year via railroad. This has translated to stringent safety measures taken to alleviate the effects of accidents involving tank cars carrying these HAZMATs. One of such measures is in the creation of the thermal protection system of tank cars in which the tank car must have sufficient thermal resistance when subjected to a simulated pool fire for 100 mins and a torch fire for 30 mins without its back plate temperature exceeding 427 ºC at any point of time. This requires a suitable material as a thermal blanket and insulation in tank car lining. Steel-steel composite metal foam (S-S CMF) is a novel metal foam with unique properties of high strength to density ratio, lightweight, and high energy absorption. It consists of metallic hollow spheres that are closely packed within a metal matrix. The large percentage of air within the hollow spheres provide both lightweight and insulating effects for CMF. S-S CMF is being investigated using the standard torch fire test requirement to determine its suitability as a material for tank car thermal protection. This is accomplished by developing a numerical model using the Fire dynamics simulator (FDS) as a form of validation for experimental work done. To properly evaluate this, there are various thermal properties of S-S CMF that need to be established for predicting CMF’s thermal response. Surface emissivity has been a challenging property to evaluate and hence this study focuses on developing an experimental and numerical procedure in evaluating this property for composite materials such as CMF. Preliminary data shows an acceptable prediction of emissivity, which will be applied to the FDS model for the torch fire test.

Metallic residues are distributed heterogeneously onto small-arms range soils from projectile fragmentation upon impact with a target or berm backstop. Incremental Sampling Methodology (ISM) can address the spatially heterogeneous contamination of surface soils on small-arms ranges, but representative kilogram-sized ISM subsamples are affected by the range of metallic residue particle sizes in the sample. This study compares the precision and concentrations of metals in a small-arms range soil sample processed by a puck mill, ring and puck mill, ball mill, and mortar and pestle prior to analysis. The ball mill, puck mill, and puck and ring mill produced acceptable relative standard deviations of less than 15% for the anthropogenic metals of interest (Lead (Pb), Antimony (Sb), Copper (Cu), and Zinc (Zn)), with the ball mill exhibiting the greatest precision for Pb, Cu, and Zn. Precision by mortar and pestle, without milling, was considerably higher (40% to >100%) for anthropogenic metals. Media anthropogenic metal concentrations varied by more than 40% between milling methods, with the greatest concentrations produced by the puck mill, followed by the puck and ring mill and then the ball mill. Metal concentrations were also dependent on milling time, with concentrations stabilizing for the puck mill by 300 s but still increasing for the ball mill over 20 h. Differences in metal concentrations were not directly related to the surface area of the milled sample. Overall, the tested milling methods were successful in producing reproducible data for soils containing metallic residues. However, the effects of milling type and time on concentrations require consideration in environmental investigations.

Annotation:
Current design of pipelines calls for overmatching weld metal tensile strength, forcing deformation to occur in the base material and not in the weld. If straining of the weld metal were to occur, higher levels of weld metal toughness would be required to prevent fracture initiation from pre-existing defects. There are three known issues related to the Submerged Arc Welding (SAW) double jointing of pipeline steels: - Consistently achieving weld metal strength and toughness requirements. - Heat affected zone (HAZ) softening of the base material. - Lack of an accepted test protocol for the entire range of pipe grades. The results herein will help improve the quality and efficiency of SAW welding in double jointing for all pipeline steels, and enhance industry's ability to complete double jointing and standardize its acceptance, and will improve construction efficiency, pipeline reliability and safety by addressing this important research gap in transmission pipeline welding.
