Abstract:

Purpose This paper aims to develop the Hybrid feature descriptor and probabilistic neuro-fuzzy system for attaining the high accuracy in face recognition system. In recent days, facial recognition (FR) systems play a vital part in several applications such as surveillance, access control and image understanding. Accordingly, various face recognition methods have been developed in the literature, but the applicability of these algorithms is restricted because of unsatisfied accuracy. So, the improvement of face recognition is significantly important for the current trend. Design/methodology/approach This paper proposes a face recognition system through feature extraction and classification. The proposed model extracts the local and the global feature of the image. The local features of the image are extracted using the kernel based scale invariant feature transform (K-SIFT) model and the global features are extracted using the proposed m-Co-HOG model. (Co-HOG: co-occurrence histograms of oriented gradients) The proposed m-Co-HOG model has the properties of the Co-HOG algorithm. The feature vector database contains combined local and the global feature vectors derived using the K-SIFT model and the proposed m-Co-HOG algorithm. This paper proposes a probabilistic neuro-fuzzy classifier system for the finding the identity of the person from the extracted feature vector database. Findings The face images required for the simulation of the proposed work are taken from the CVL database. The simulation considers a total of 114 persons form the CVL database. From the results, it is evident that the proposed model has outperformed the existing models with an improved accuracy of 0.98. The false acceptance rate (FAR) and false rejection rate (FRR) values of the proposed model have a low value of 0.01. Originality/value This paper proposes a face recognition system with proposed m-Co-HOG vector and the hybrid neuro-fuzzy classifier. Feature extraction was based on the proposed m-Co-HOG vector for extracting the global features and the existing K-SIFT model for extracting the local features from the face images. The proposed m-Co-HOG vector utilizes the existing Co-HOG model for feature extraction, along with a new color gradient decomposition method. The major advantage of the proposed m-Co-HOG vector is that it utilizes the color features of the image along with other features during the histogram operation.

Abstract:

This experimental research aims to characterize the complex compound M-curcumin (M=Cu, Co, Ag) based on turmeric (Curcuma longa Linn) rhizome as a candidate for photosensitizer in solar cells. The basic material used for manufacturing the M-curcumin complex compound in this study was curcumin from turmeric rhizome extract added to Cu2+, Co2+, and Ag+ metal ions. The results of the synthesis of the M-curcumin complex were characterized by FTIR and Uv-Vis spectrophotometers. The FTIR spectrophotometer test showed a curcumin compound in the viscous curcumin extract, characterized by an absorption wave number corresponding to the curcumin compound. In the M-curcumin complex, the bond between the metal and the ligand only appears in the Co-curcumin complex at the absorption number of 498.77 cm -1. The results of the UV-Vis spectrophotometer test showed that the maximum wavelength absorption in curcumin extract was 430 nm (abs = 0.688), Cu-Curcumin complex lmax 300 nm (abs = 2.573), Co-curcumin complex lmax 425 nm (abs = 1.067), and complex Ag-Curcumin lmax 430 nm (abs = 1.36). The UV-Vis and FTIR characterization showed that the Co-curcumin complex has good potential compared to the organic compounds (curcumin) and can be used as an alternative photosensitizer in solar cells

Abstract:

Flexible Manufacturing Systems-FMS is a term with various types of definitions, each of them trying to describe the complexity and the generalized features. One of these features is their complexity, along with difficulties in building models that capture the system in all its important aspects. In a heterogeneous flexible system, the scheduling events or actions could be a combinatorial problem which claims a particular solution. Manufacturing scheduling process, in special for FMS, is a very difficult scheduling problem, because involves all the aspects of the processes: order, resources, transportation system i.e. automated vehicle guided, perturbation factors such as breakdowns of machine, etc. Typically, the scheduling problem is a NP-hard problem modeled in mathematical form. If we simulate n jobs or orders which have to be assigned to the m machines or resources, we will observe that the mathematical solution is a huge number that means (n!)m possibilities of solutions. The challenge of researchers is to solve this equation in a reasonable time with an optimal solution, and of course with minimal resources. Those scientists applied many solutions which became Operational Research-OR or Combinatorial Optimization-CO areas using a various methods: Local Search-LS, Artificial Intelligence-AI, heuristic method, priority rules, memetic or hybrid techniques which combine this techniques.

Abstract:

In this publication, the potential non-gadolinium magnetic resonant imaging agent—nanoparticulate K2Mn[Fe(CN)6]—its comparison sample KFe[Co(CN)6], as well as their reference samples were measured and analyzed using Mn, Co and Fe L-edge X-ray absorption spectroscopy (L XAS). From the information obtained, we conclude that K2Mn[Fe (CN)6] has a high spin (hs)-Mn(II) and a low spin (ls)-Fe(II), while KFe[Co(CN)6] has an hs-Fe(II) and an ls-Co(III). In these Prussian blue (PB) analog structures, the L XAS analysis also led to the conclusion that the hs-Mn(II) in K2Mn[Fe(CN)6] or the hs-Fe(II) in KFe[Co(CN)6] bonds to the N in the [M(CN)6]4−/3− ions (where M = Fe(II) or Co(III)), while the ls-Fe(II) in K2Mn[Fe(CN)6] or the ls-Co(III) in KFe[Co(CN)6] bonds to the C in the [M(CN)6]4−/3− ion, suggesting the complexed metalloligand [Mn(II) or Fe(II)] occupies the N-bound site in PB. Then, nuclear resonant vibrational spectroscopy (NRVS) was used to confirm the results from the L XAS measurements: the Mn(II), Eu(III), Gd(III), Fe(II) cations complexed by [M(CN)6]n−-metalloligand all take the N-bound site in PB-like structures. Our NRVS studies also prove that iron in the K2Mn[Fe(CN)6] compound has a 2+ oxidation state and is surrounded by the C donor atoms in the [M(CN)6]n− ions.

Abstract:

Abstract Due to their small size, low-power demands, and customizability, low-cost sensors can be deployed in collections that are spatially distributed in the environment, known as sensor networks. The literature contains examples of such networks in the ambient environment; this article describes the development and deployment of a 40-node multi-hazard network, constructed with low-cost sensors for particulate matter (SHARP GP2Y1010AU0F), carbon monoxide (Alphasense CO-B4), oxidizing gases (Alphasense OX-B421), and noise (developed in-house) in a heavy-vehicle manufacturing facility. Network nodes communicated wirelessly with a central database in order to record hazard measurements at 5-min intervals. Here, we report on the temporal and spatial measurements from the network, precision of network measurements, and accuracy of network measurements with respect to field reference instruments through 8 months of continuous deployment. During typical production periods, 1-h mean hazard levels ± standard deviation across all monitors for particulate matter (PM), carbon monoxide (CO), oxidizing gases (OX), and noise were 0.62 ± 0.2 mg m−3, 7 ± 2 ppm, 155 ± 58 ppb, and 82 ± 1 dBA, respectively. We observed clear diurnal and weekly temporal patterns for all hazards and daily, hazard-specific spatial patterns attributable to general manufacturing processes in the facility. Processes associated with the highest hazard levels were machining and welding (PM and noise), staging (CO), and manual and robotic welding (OX). Network sensors exhibited varying degrees of precision with 95% of measurements among three collocated nodes within 0.21 mg m−3 for PM, 0.4 ppm for CO, 9 ppb for OX, and 1 dBA for noise of each other. The median percent bias with reference to direct-reading instruments was 27%, 11%, 45%, and 1%, for PM, CO, OX, and noise, respectively. This study demonstrates the successful long-term deployment of a multi-hazard sensor network in an industrial manufacturing setting and illustrates the high temporal and spatial resolution of hazard data that sensor and monitor networks are capable of. We show that network-derived hazard measurements offer rich datasets to comprehensively assess occupational hazards. Our network sets the stage for the characterization of occupational exposures on the individual level with wireless sensor networks.

Abstract:

Lithium ion batteries (LIBs) with high specific capacity and long cycle life is critically required for high energy applications, such as electric vehicle technology. Owing to the high capacity, various Ni-rich cathodes (with Ni-content ≥ 80 %), including lithium-nickel-cobalt-manganese (NCM), lithium-nickel-cobalt-aluminum (NCA)-based layer oxides are widely explored to fabricate high performance LIBs.1 However, increase in Ni-content in the layered oxides aggravated the issues like, poor rate capability and short cycling performance due to the extensive volume contraction/expansion and the phase change above 4.2 V vs. Li/Li+. One rational strategy to achieve both high capacity and high mechanical stability for the Ni-rich cathodes is optimized doping of Al in the NCM moiety. Presence of Mn and Al in the same structure ensures high mechanical as well as thermal stability of the lithium-nickel-cobalt-manganese-aluminum oxide (NCMA).2 The performance of NCMA largely depends on the atomic percentage of each transition metals in the crystal structure. Hence proper control over the elemental composition and morphology is critically required. Among the various synthesis methods, stirred tank reactor-based co-precipitation synthesis through batch or semi-batch process is commonly used to synthesize phase pure NCMA precursors. However, the stirred tank reactor-dependent synthesis of battery precursors suffers from intrinsic batch-to-batch composition variability, increased agglomeration/breakage of particles and scaling up issues. The main goal of our research is to develop a low-cost scalable manufacturing platform for Ni-rich cathodes.3 Herein, we have utilized three-phase slug-flow reactor to produce NCMA oxalate precursor particles with high phase purity, homogeneity in composition and uniformity in particle size distribution (Figure 1). Here, the growth of precursor particles follows the co-precipitation chemistry and each of the self-circulating slugs works as the milliliter scale reactors, which offers better mixing of various reagents of the reaction mixture.3 The reactor is advantageous in terms of selective feeding of components, spatially uniform reaction conditions with high production rate and good control over the precursor composition and particle size, which further determines the tap density of the final material.4 In this work, NCMA oxalate with the compositional variation of Co= 6 – 10 % are synthesized through slug-flow, followed by high temperature lithiation of the precursor at high temperature of 750 oC in oxygen flow to obtain the final oxide material. The ammonium oxalate was used as the primary precipitation agent and ammonium hydroxide plays the roles of pH-controller as well as works as the chelating agent. The as-synthesized NCMA shows a high specific capacity of ~196 mAh g-1 at 0.1 C. The battery performance of the NCMAs are further analyzed by rate capability and cycling performance profiles.

Abstract:

Buttabean Motivation (BBM) is a grassroot initiative aiming to improve Pasifika and M?ori health through free community bootcamps offering exercise, motivation and nutritional advices, and with online programmes of workouts and meal plans. It is a dynamic organisation, responding to community needs, providing practical solutions to issues such as food insecurity and influenza vaccination while maintaining its core focus of reducing obesity among Pasifika and M?ori through nutrition and physical activity.. BBM forms active and changing relationships with numerous organisations that offer support. They would like to work with the government and the district health boards, but the structure and changing nature of their organisation does not fit traditional funding models. To show that BBM is effective for Pacific people beyond anecdotal evidence, BBM has partnered with University of Auckland researchers. The research team are using a kaupapa M?ori and co-design approach to explore how BBM might benefit the community and reduce health inequities, especially whether BBM’s model of social collectivism enables sustainable weight loss for Pasifika and M?ori in the current obesogenic environment. Weight reduction programmes typically find that after initial success, participants have reverted to pre-programme weight by five years. BBM’s “whole of life change” approach may lead to sustained weight loss not demonstrated by other programmes. Using co-design, a BBM/University of Auckland partnership is evaluating the effectiveness of the BBM programme for sustained health and wellbeing. BBM is grounded in the Pacific/indigenous health frameworks fonofale, te whare tapa wh? and fa’afaletui addressing physical, mental, spiritual, family and social health in the context of people’s lives. The research will use a longitudinal cohort approach study design, using metrics and outcomes of relevance to its participants and the programme. A systems analysis will facilitate understanding of the strengths and challenges to delivering a holistic and sustained service for the community. BBM provides much promise in reducing health inequities for Pasifika and M?ori, however the model creates challenges for ongoing funding, business structure and evaluation. The goal is to find ways that both the programme and social institutions, including funders and evaluators, can adapt to meet these real-world challenges.

Abstract:

The main goal of this research is to develop a low-cost scalable continuous manufacturing platform for Ni-rich cathodes. In this work, we demonstrate the synthesis and electrochemical performance of Ni-rich layered oxide [Li[Ni0.8Mn0.1Co0.1]O2 (NMC811)], an efficient low-cobalt cathode for the next generation lithium-ion batteries using a three-phase slug-flow reactor.1-5 The slug flow reactor is used to continuously produce uniform, high purity NMC811 with spherical morphology using oxalate precursor chemistry. The precursor material is then reacted with Li salts to prepare high purity cathode materials. The as-prepared NCM811 possess a high tap density of 2.4 g mL-1 and a high specific capacity of 202 mAh g-1 at 0.1C.5 A novel coating method has been developed to produce a stable LiF layer on the cathode surface to improve the cycling stability of the material.6 This work will discuss in detail about the synthesis procedure, microstructural and electrochemical performance of the cathode material produced by the slug flow manufacturing process. This demonstration provides a pathway towards scaling up the cathode synthesis process for large-scale energy storage applications.3 Acknowledgements This research was supported by the U.S. Department of Energy, Office of Energy Efficiency and Renewable Energy, Advanced Materials and Manufacturing Technologies Office, the National Science Foundation (Grant No. CMMI-1940948).

Abstract:

Morphological characteristics of the southwestern deep-depression East Sea have been defined based on the subdivision into co-origin surfaces. The results show that, the study area has 16 morphological units, including: Horizontal surface, slightly inclined surface, continental shelf accumulation, 200÷300 m depth; The surface is slightly inclined and wavy accumulates the outer shelf, 300÷700 m deep; Horizontal surface, abrasive, 500÷700 m (Guyot); Abrasive horizontal surface (Guyot), depth 1,300÷1,600 m; Abrasive horizontal surface (Guyot), depth -2,000 m; The surface of the ancient volcanic crest is distributed at different depths; Young volcanic surface, 1,200÷3,000 m deep; Wavy, accumulative plain, continental rise, 1,100÷1,800 m deep; Plain transport - accumulation plain, depth 1,100÷2,300 m; The smooth plain transports accumulates, depth 2,300÷3,000 m; The plain is divided by underground hills and mountains in the north, 2,000÷2,600 m deep; The plain is strongly dissected of underground mountains, 1,700÷2,600 m deep; Deep depression surface splits; Tectonic slope surface, continental slope 800÷1,400 m depth; Slope surface of the Northwestern underground mountain range 1,800÷2,600 m; Slope surface of the Southeastern underground mountain range 2000÷2900 m.

Abstract:

The aim of this work is to analyze the possibility of producing a joint by lamination of an Al-1050 plate and Fe78Si9B13(%at.) soft magnetic ribbons material obtained by a rapid solidification process by using the Melt Spinning (MS) technique. The lamination conditions are studied on the characteristics of the joint, the microstructure, and the magnetic properties. Mainly the surface preparation, temperature, and reduction of thickness. The material is characterized by X-Ray Diffraction, Optical, and Scanning Electron Microscopy, showing a completely amorphous structure before and after the collamination, the typical defects caused by this rapid solidification technique in ribbons (bubbles, dust particles, roughness imperfections and oxides) and the joint between materials. The microhardness Vickers has been determined in both, the ribbons as quenched and collaminated samples, to observe quantitatively the hardening suffered during colamination and find a possible cause. The Differential Scanning Calorimetry and Compositional Analysis by EDS techniques were also used to determine the crystallization temperatures and chemical exact chemical composition of the ribbons as received. The magnetic hysteresis curve of the amorphous ribbons showed a Hc and Ms around 3.8 A/m and 1.44 T correspondingly.

Abstract:

According to the United Nations Environment Programme (UNEP), the construction and operation of buildings accounted for nearly 38% of total global energy-related CO₂ emissions in 2019. The construction sector has been striving to use more low-carbon footprint building products to mitigate climate change and enhance environmentally preferable purchasing. Over the last several decades, there has been substantial growth in engineered wood products for the construction industry. To assess these products used in construction for their environmental profile, lifecycle assessments (LCAs) are performed. This study performed an LCA to estimate environmental impacts (cradle-to-gate and gate-to-grave) of cellulosic fiberboard (CFB) per m³ functional unit basis. The lifecycle inventory data developed were representative of CFB production in North America. Overall, the cradle-to-grave LCA results per m3 of CFB were estimated at 305 kg CO₂ e global warming (GW), 19.3 kg O₃ e photochemical smog formation, 1.03 kg SO₂ e acidification, 0.33 kg N e eutrophication, and 415 MJ fossil-fuel depletion. Except for smog formation, most environmental impacts of CFB were from cradle-to-gate. For example, 71% and 29% of total GW impacts were from cradle-to-gate and gate-to-grave lifecycle stages, respectively. The sensitivity analysis showed that reducing transport distance, on-site electricity use, natural gas for drying, and starch additives in the manufacturing phase had the most influence. Around 353 kg CO₂ e/m³ of CFB is stored as long-term carbon during CFB’s life which is higher than the total cradle-to-grave greenhouse gases (CO₂ e) emissions. Thus, the net negative GW impact of CFB (-47 kg CO₂ e/m³ of CFB) asserted its environmental advantages as an engineered wood panel construction material. Overall, the findings of the presented study would prove useful for improving the decision-making in the construction sector.

Full text

Abstract:

A comparative study was set up in order to assess the technical feasibility of the long-term reuse of the mechanically separated co-digested solid fraction as a feedstock for anaerobic digestion plants (ADP). The biogas yields of two feedstock mixtures (A and B) were assessed in mesophilic conditions (40°C±2°C) using 6 lab-scale continuous stirredtank reactors. Feedstock mixture A (control) consisted of pig slurry (70%), farmyard manure (4%), sorghum silage (12%) and maize silage (14%). Feedstock mixture B was the same as the control plus the solid fraction derived from the mechanical separation of the output raw codigestate collected from the reactors. All reactors were fed simultaneously, three times a week, over a period of nine month. According to the study results, the reuse of the co-digested solid fraction as feedstock for ADP could increase the methane yield by approximately 4%. However, ADP efficiency evaluation (<em>e.g.</em>, daily yield of methane per m<sup>3</sup> of digester) suggests limiting this practice to a maximum time period of 120 days.

Full text

Abstract:

Fe-based amorphous materials offer new opportunities for magnetic sensors, actuators, and magnetostrictive transducers due to their high saturation magnetostriction (λs = 20–40 ppm) and low coercive field compared with polycrystalline Fe-based alloys, which have high magnetostriction but large coercive fields and Co-based amorphous alloys with small magnetostriction (λs = −3 to −5 ppm). Additive layer manufacturing (ALM) offers a new fabrication technique for more complex net-shaping designs. This paper reviews the two different ALM techniques that have been used to fabricate Fe-based amorphous magnetic materials, including the structural and magnetic properties. Selective laser melting (SLM)—a powder-bed fusion technique—and laser-engineered net shaping (LENS)—a directed energy deposition method—have both been utilised to fabricate amorphous alloys, owing to their high availability and low cost within the literature. Two different scanning strategies have been introduced by using the SLM technique. The first strategy is a double-scanning strategy, which gives rise to maximum relative density of 96% and corresponding magnetic saturation of 1.22 T. It also improved the glassy phase content by an order of magnitude of 47%, as well as improving magnetic properties (decreasing coercivity to 1591.5 A/m and increasing magnetic permeability to around 100 at 100 Hz). The second is a novel scanning strategy, which involves two-step melting: preliminary laser melting and short pulse amorphisation. This increased the amorphous phase fraction to a value of up to 89.6%, and relative density up to 94.1%, and lowered coercivity to 238 A/m. On the other hand, the LENS technique has not been utilised as much as SLM in the production of amorphous alloys owing to its lower geometric accuracy (0.25 mm) and lower surface quality, despite its benefits such as providing superior mechanical properties, controlled composition and microstructure. As a result, it has been commonly used for large parts with low complexity and for repairing them, limiting the production of amorphous alloys because of the size limitation. This paper provides a comprehensive review of these techniques for Fe-based amorphous magnetic materials.

Abstract:

The electrical discharge machining-process (EDM) is a smart solution to optimize the manufacturing chain of customized and complex shaped ceramic components. To comply with the high requirements for the machine and mold design, it is necessary to improve the mechanical properties of ED-machinable ceramics. In this study, ceramic composites with a tetragonal zirconia matrix and tungsten carbide as electrically conductive dispersion were investigated. To improve the toughness of this high strength material, co-stabilized zirconia coated with yttria and neodymia as dopants were used in the compositions with 1.5/1.5 and 1.75/1.25 mol %. These recipes were compared to commercial 3Y-TZP as a reference matrix material combined with the same WC raw powder. The electrically conductive phase content was varied from 20 to 28 vol %. For all compositions, the ceramic blanks were hot pressed at identical dwell and pressure, but with various sintering temperatures (1300 °C to 1450 °C) and then tested with respect to the mechanical and electrical properties. By variation of the stabilizer system, a significantly higher toughness of up to 11.3 MPa√m compared to 5.3 MPa√m for 3Y-TZP-20WC is achieved while the bending strength stays at a comparable high level of >1500 MPa.

Abstract:

Using the technology of cold metal transfer (wire-arc additive manufacturing combined with welding surfacing), a coating is formed on a 5083 alloy substrate with a high-entropy Mn-Fe-Cr-Co-Ni alloy of nonequiatomic composition. Analysis of the structure, elemental composition, and microhardness of the coating-substrate system is carried out using the methods of modern physical materials science. A significant increase (up to 9.9 GPa) in the microhardness of the material is found in the zone of contact between the coating and the substrate. The formation of lamellar inclusions (Al13F4) enriched in coating atoms in the zone of contact between the coating and the substrate is revealed. The high entropy coating in the contact zone has a submicrocrystalline grain-subgrain structure with a crystallite size ranging from 0.5 ^m to 1.1 ^m along the boundaries where nanosized particles of the second phase (Al3Ni) are revealed. The volume of grains contains a dislocation substructure in the form of randomly distributed dislocations or dislocation clusters. The scalar density of the dislocations is (0.8-1.0)-1010 cm-2. An assumption is made about the physical mechanisms of hardening of the material in the "coating-substrate" contact zone. Key words: high-entropy alloy, coating / substrate system, aluminum alloy, elemental and phase composition, microhardness, hardening.

Abstract:

Haber-Bosch fertilizer production has enabled large-scale food production; however, the process demands exorbitant energy inputs while yielding direct atmospheric carbon emissions, and the resulting anthropogenic perturbations to the global nitrogen cycle threaten water quality. Enabling a sustainable food-energy-water nexus requires feeding a growing population while minimizing environmental impacts. Molecular catalysis of aqueous electrochemical nitrate reduction (NO3RR) to ammonia can simultaneously reduce nitrogen pollution and electrify ammonia manufacturing. While several Co-N4 complexes have been explored as molecular catalysts for aqueous NO3RR, such as CoIII–cyclam and CoIII–protoporphyrin,1,2 the metal complex we focus on in this talk is the cobalt–centered macrocycle [Co(DIM)Br2]+ (DIM = 2,3-dimethyl-1,4,8,11-tetraazacyclotetradeca-1,3-diene: abbreviated as Co(DIM)) because it remains the only water-soluble catalyst that has been reported to yield ammonia from NO3RR with near full selectivity (> 95%).3–5 50 years have passed since Co(DIM) was synthesized in 1972. Yet despite the promise Co(DIM) holds for advancing progress towards molecular-catalyst-enabled wastewater-NO3RR, the few existing studies on Co(DIM) focus primarily on the structural and electronic properties of Co(DIM) that contribute to selective nitrate and nitrite conversion.5–8 A dearth of experimental investigations prevents the rational design and implementation of NO3RR molecular platforms such as Co(DIM). From an electroanalysis standpoint, kinetic benchmarking of Co(DIM)-mediated NO3RR would contextualize the performance of Co(DIM) relative to state-of-the-art molecular electrocatalysts and quantitatively facilitate optimization goals for next-generation NO3RR molecular catalysts. While turnover frequency (TOF) vs. overpotential (η) relationships are reported for HER, ORR, and CO2RR molecular electrocatalysts, to date, such a relationship has not been reported for any molecular NO3RR electrocatalyst. And salient to any molecular electrocatalyst, studies on the operational stability of Co(DIM) are needed to provide greater insight into the conditions that contribute to catalyst instability and thus strategies to avoid catalyst degradation. In this work, we propose an ECEC mechanism that governs the kinetics of Co(DIM)-mediated NO3RR. From first-principles, we solve a 1D reaction-diffusion model that relates catalytic current to applied potential and validate the model through fitting experimental, voltammetric data. Through foot-of-the-wave and plateau current analysis, we evaluate the turnover frequency (TOF) vs. overpotential (η) relationship for Co(DIM)-mediated NO3RR. These methods provide approximations for TOF0, a measure of intrinsic kinetics, and TOFmax, the TOF achievable by Co(DIM) in the absence of interfacial nitrate depletion and catalyst degradation. TOF values from controlled potential electrolysis (CPE) experiments are consistently lower than TOFmax, and we identify two key reasons for the discrepancy. First, interfacial substrate depletion due to mass transfer limitations prevents TOFmax from being achieved during CPE. Second, catalyst degradation in alkaline environments, as demonstrated via characterization of the electrode (XPS, SEM-EDX, and XRD) and electrolyte (UV-VIS, IC), leads to loss in activity. Through in situ CVs and ex situ rinse tests (CPE involving electrodes with surface immobilized degradation products and no Co(DIM) in solution), we demonstrate that the degradation products likely play a small catalytic role compared to Co(DIM), highlighting the importance of maintaining the structural integrity of Co(DIM) during CPE operation. This work addresses several critical knowledge gaps surrounding Co(DIM)-mediated NO3RR in order to meet the scale and urgency of electrochemically remediating nitrogen emissions and producing ammonia.

Abstract:

AbstractThe failure of tools will make a large impact to the productivity, so it must be investigated to avoid the next failure. In this case, the super hard end mill HSS-Co list 4SE code 6210 was broken when it was used for side milling processing of mild steel AISI A36 with rotation speed, cutting speed and cutting depth of 540 rpm, 0.10 m/min (4 ipm) and 16 mm respectively. Standard procedure of failure analysis was performed including macro-micro investigation using Scanning Electron Microscopy (SEM) with energy-dispersive spectrometry (EDS) attachment, micro hardness test, and Finite Element Methods (FEM) simulation. The results of failure analysis showed that fracture occurred due to stress concentration and micro defects of the super hard end mill. Two parts of fracture surface, rough and fine surface were found. Based on SEM-EDS investigation, it was known that the content of tungsten (W) and cobalt (Co) elements on the rough and fine surface was inhomogeneous. Excessive Co and W elements appeared on the fine surface while they disappeared on the rough surface. Excessive Co will diffuse with tungsten and carbon and lead to the separation of tungsten and carbon elements, so it greatly destroyed the alloys and lead to form the non-stoichiometry carbide points. Hence, the defective manufacturing processes which made the elements distribute inhomogeneous is concluded as the reason of the super hard end mill failure.

Abstract:

This paper deals with the comparative study of the dispersion of some components of flue gases in the atmosphere. Mathematical modelling of the dispersion of pollutants discharged from technological furnaces in refineries is carried out using high-performance software. Thus, taking into account the meteorological conditions and the pollutant concentrations, the level of atmospheric pollution can be determined. The aim of the paper is to compare the values of NO2 and CO concentrations obtained with the classical Gaussian dispersion model algorithm with the values of pollutant concentrations estimated using the SCREEN View simulation software. The determinations were made taking into account receivers located at distances of 100 m, 500 m, 2500 m and 5000 m from the emission source, thus it was established at which distance from the source the maximum pollutant concentrations resulted. For atmospheric stability class, A and F (very unstable and stable). For A stability class, the maximum concentrations pollutant resulted at a distance of 500m from the emission source, and for F stability class, the maximum pollutant concentrations resulted at a distance of 2500 m from the emission source. Both with the classic work methodology and with the SCREEN View software, the concentration values are comparable, this underlines the precision of the software. Also, with the classic Gaussian modelling algorithm, the maximum height of the smoke plume was calculated. This is higher for stability class A, compared to F.
