Résumé :
Abstract Carbon dioxide was reduced to methane by visible-light irradiation of a solution composed of tris(bipyridine)ruthenium(III) as photosensitizer, ethylenediaminetetraacetic acid disodium salt as sacrificial reagent, methyl viologen as electron relay, and a colloidal dispersion of polymer-protected noble-metal clusters, prepared by alcohol-reduction, as catalyst. Among the noble-metal clusters examined, Pt clusters showed the highest activity for the formation of methane as well as hydrogen. In order to improve the activity, oxidized clusters and bimetallic clusters were also applied. For example, the CH4 yield in 3-h irradiation increased from 51 x 10-3 μmol with unoxidized Pt clusters to 72 x 10-3 μmol with partially oxidized ones. In the case of Pt/Ru bimetalic systems, the improvement of the catalytic activity by air treatment was much greater than in case of monometallic clusters.

Résumé :
New types of profile products make complex use of bimetals. These materials possess a set of properties such as strength, corrosion resistance, thermal conductivity, heat resistance, wear resistance. For the processing of such products, it is advisable to use electrophysical processing methods, one of which is the technology of copy-piercing electrical discharge machining (EDM). Currently, EDM is one of the most common methods for processing products from modern bimetal materials. An urgent task is to study the EDM process of bimetallic materials. The aim of the work was to increase the efficiency and accuracy of the EDM process of bimetallic products using electrode-tools with different physical and mechanical properties. Bimetal—weld coated steel backing, base material—09G2S steel, surfacing material—M1 copper were used. The processing of the bimetallic workpiece was carried out on an Electronica Smart CNC copy-piercing EDM machine. EI used graphite, copper, and composite. A theoretical model was developed that allows calculation of the amount of removal of bimetallic material of steel–copper depending on the EDM modes and the ET (electrode tool) material. During the processing of the steel layer, regardless of the EI material, microcracks were formed along the grain boundaries, and during the processing of the copper layer, enlarged holes resulted.

Résumé :
Volatile organic compounds (VOCs) and methane are pollutants that are harmful to the atmosphere and human health. It is highly required to control emissions of VOCs. Catalytic oxidation is one of the most effective pathways for the elimination of VOCs, in which the key issue is the development of novel and high-performance catalysts. In this review article, we briefly summarize the preparation strategies, physicochemical properties, catalytic activities, and stability for the oxidative removal of VOCs of the supported bimetallic catalysts that have been investigated by our group and other researchers. The supported bimetallic catalysts include the supported noble bimetal, supported noble metal-transition metal, and supported non-precious bimetal catalysts. It was found that catalytic performance was related to one or several factors, such as specific surface area, pore structure, particle size and dispersion, adsorbed oxygen species concentration, reducibility, lattice oxygen mobility, acidity, reactant activation ability, and/or interaction between bimetals or between metal and support. The stability and ability of anti-poisoning to water, carbon dioxide or chlorine were related to the nature of the bimetal and support in the catalysts. In addition, we also envision the development trend of such a topic in the future work.

Résumé :
The analysis of existing methods and a new combined process of bimetal production are presented, according to which a special regular design of holders is created on the surface of its functional component by means of laser or arc welding. Themelt of the structural component of the bimetal is fed to the surface of the functional component through the hole in the form of a special device with a given flow rate. Holders are made of wire. The holders are located on the surface of the working plate at an angle or perpendicular to the base, followed by bending after assembly. The number of holders, their geometry and relative position on the surface are determined by the size of the bimetal. You can change the required parameters of the strength of adhesion in different areas. Full filling of technological space between holders filled with metal guarantees reliable fastening ofbimetallic plates. Various options have been developed and implemented to reduce the cost of bimetal production technology. There are options where not the whole surface is filled, but only the specified areas of the prepared holes. This allows to implement multi-layer metal structures. A cheap and simple method of obtaining bimetallic plates without the need for foundry operations and equipment is the use of welding technology. It has been proven that in order to ensure high bond strength of bimetallic components and uniform distribution on the joint plane, it is necessary that the frequency of the holders and the step between them havethe optimal value. The high efficiency of a new, innovative combined technology of bimetal production has been demonstrated.The introduction of these technologies in the production of bimetals does not require large material costs and ensures maximum profitability of the manufacturing process of such materials. The presence of several manufacturing methods allows you to select the most optimal technology depending on the volume of production and the size of the resulting sheets of bimetals or individual products from them.

Résumé :
Carbon nanotube (CNT) arrays have been synthesized by a repeated growth method using a custom-fabricated plasma-enhanced thermal chemical vapor deposition (PE-thermal CVD) apparatus. The initial catalyst is a layered structure prepared by depositing 10 nm of Al followed by 3 nm of Fe on an oxidized silicon substrate. Following CNT growth, the CNT arrays are removed using an ultrasonic cleaner, and another CNT array is grown on the remaining Fe-Al bimetalic nanoparticles without the addition of more catalyst. Annealing the catalytic substrate in air between growth cycles results in the removal of residual amorphous carbon along with the CNTs, and oxidation of the Fe-Al nanoparticles. The diameter of CNTs is reduced with repeated growth-annealing cycles, an effect of which is attributed to the diminishing size of the catalytically active nanoparticles with each cycle. After two growth cycles, SWNTs with the extraordinarily narrow diameter of 0.86 nm are synthesized. TheID/IGratio derived from the Raman spectrum of these of the SWNT arrays shows the remarkably low value of 0.22.

Abstract: Carbon supported PdAu nanoparticles with different Au contents (20-50% in atoms) were synthesized using a procedure carried out in a liquid two-phase system. As-prepared materials presented similar average particle diameter (~3nm) with narrow distribution over the carbon support, as shown by Transmission Electronic Microscopy (TEM). The combined data from X-ray Diffraction (XRD) and X-ray Photoelectron Spectroscopy (XPS) suggest that nanoparticles had Pd-enriched surfaces and Au-rich interiors. Cyclic Voltammetry (CVs) studies in H2SO4 further reinforced these findings, confirming that the nanoparticle surfaces were enriched with Pd. Moreover, XPS results show that increasing the Au content of PdAu alloys leads to varying amounts of surface-like and bulk-like Pd oxide, with a significant increase of metallic Pd. This result is consistent with data of X-ray Absorption Spectroscopy (XAS) around Pd L3 edge, which revealed that Au promotes an increase in the electronic occupancy of the Pd 4d band. Therefore, this whole set of characterizations suggests that the presence of Au in PdAu nanoalloys decreases the Pd affinity for oxygen, giving Pd a more noble-like character. In addition, the influence of ligand and ensemble effects on electrochemical surface processes, such as oxide formation/reduction, CO oxidation and hydrogen adsorption were also investigated. This was also a necessary step in order to determine the best technique to measure the Electrochemical Active Area (EAA) of... (Complete abstract click electronic access below)
Resumo: Nanopartículas de PdAu suportadas em carbono com diferentes frações de Au (20-50% em átomos) foram sintetizadas em um sistema líquido de duas fases. As nanopartículas preparadas apresentaram diâmetro médio próximo a 3 nm, com uma distribuição homogênea sobre o suporte de carbono, o que foi demonstrado por microscopia eletrônica de transmissão (TEM). O conjunto dos dados coletados por difração de raios X (XRD) e por espetroscopia de fotoelétrons excitados por raios X (XPS) demonstrou que o interior das nanopartículas é enriquecido por Au, enquanto a superfície é mais rica em Pd. A análise por XPS também demonstrou que o aumento da fração de Au nas ligas de PdAu leva a uma variação na fração de diferentes espécies de óxidos de Pd e um aumento na quantidade total de Pd metálico. Este resultado é consistente com aquele obtido por espectroscopia de absorção de raios-X (XAS), realizada na borda L3 do Pd, a qual revelou que o Au promove um preenchimento eletrônico na banda 4d do Pd. Ou seja, a presença do Au parece diminuir a afinidade do Pd pelo oxigênio. Ademais, foram estudados a influência de efeitos eletrônicos e do arranjo superficial de átomos sobre os processos eletroquímicos de formação/redução de óxidos, oxidação de CO adsorvido e adsorção de hidrogênio. Estes estudos também permitiram a determinação da área eletroquímica ativa de Pd. Por meio de todas estas caracterizações foi possível traçar correlações entre a composição no cerne das nanopartículas de PdAu e suas propri... (Resumo completo, clicar acesso eletrônico abaixo)

Résumé :
A busca por fontes alternativas de energia é uma tendência mundial e, neste contexto, as células a combustível alimentadas com hidrogênio obtido pela reforma de biocombustíveis constitui uma das alternativas mais promissoras. Entretanto, o desempenho das células a combustível de membrana de troca protônica (PEMFC) com ânodos baseados em Pt é drasticamente reduzido quando se utiliza hidrogênio contaminado por CO, o qual é produzido no processo de reforma. Neste trabalho, a eletrocatálise da tolerância ao CO e a estabilidade de Pt/C, PtRu/C, PtFe/C, PtMo/C e PtW/C como eletrocatlisadores anódicos de célula a combustível PEM foram investigadas através de curvas de polarização e medidas on line de espectrometria de massas (EMS), análises de voltametria cíclica, difração de raios X (DRX) e absorção de raios X (XAS). Para todos os eletrocatalisadores bimetálicos, os quais apresentaram alta tolerância ao CO, os resultado de EMS mostraram que a produção de CO2 inicia-se a menores sobrepotenciais em relação ao eletrodo de hidrogênio quando comparado a Pt/C, confirmando a ocorrência do conhecido mecanismo bifuncional. Por outro lado, os resultados de XANES indicam um aumento de vacância da banda 5d da Pt para todos os catalisadores bimetálicos, particularmente para PtFe/C, o que leva a um enfraquecimento da ligação Pt-CO e conseqüente aumento da tolerância ao CO (efeito eletrônico). Para PtMo/C e PtRu/C alimentado com H2/CO, a formação de CO2 é observada mesmo quando a célula opera em circuito aberto, confirmando alguma eliminação de CO por um processo químico, muito provavelmente uma reação de deslocamento gás-água. Uma deterioração do desempenho de célula a combustível foi observada em uma função do tempo de operação. As causas desta degradação durante a operação a longo prazo fazem parte de um processo complexo que envolve diversos mecanismos paralelos, tais como: perda ou redistribuição do eletrocatalisador, corrosão do suporte de carbono e degradação do eletrólito (Nafion®).
The search for alternative sources of energy is a global trend, and in this context, the fuel cell supplied with hydrogen obtained by biofuels reforming is one of the most promising alternative. However, the performance of proton exchange membrane fuel cells (PEMFC) with Pt-based anode is drastically lowered when using CO-contain hydrogen, as that produced by reform. In this work, the electrocatalysis of CO tolerance and the stability of Pt/C, PtRu/C, PtFe/C, PtMo/C, and PtW/C electrocatalysts at a PEM fuel cell anode has been investigated using single cell polarization and on line electrochemical mass spectrometry (EMS) measurements, and cyclic voltammetry, X-ray diffraction (XRD), and X-ray absorption near edge structure (XANES) analyses of the electrocatalysts. For all bimetallic electrocatalysts, which presented higher CO tolerance, EMS results have shown that the production of CO2 starts at lower hydrogen electrode overpotentials as compared to Pt/C, confirming the occurrence of the so-called bifunctional mechanism. On the other hand, XANES results indicate an increase in the Pt 5d-band vacancies for the bimetallic catalysts, particularly for PtFe/C, this leading to a weakening of the Pt-CO bond, helping to increase the CO tolerance (the so-called electronic effect). For PtMo/C and PtRu/C supplied with H2/CO, the formation of CO2 is observed even when the cell is at open circuit, confirming some elimination of CO by a chemical process, most probably the water gas shift reaction. A decay of the fuel cell performance was observed as a function of the operation time. The causes of degradation during long-term operation were found to be a complex process that involves several parallel mechanisms, including: electrocatalyst loss or redistribution, carbon corrosion, and electrolyte (Nafion®) degradation.

Résumé :
In this thesis, I introduce bimetallic ring resonator arrays as a platform for enhancing and controlling magneto-optical and thermoelectric effects. By taking advantage of differences in the physical (optical, electronic, thermal, magnetic) properties of the two elements comprising the resonators, I have demonstrated tailoring of the optical absorption and the Faraday effect, and generation of THz magnetic pulses. In particular: I have theoretically predicted for the first time the light-driven generation of intense, highly-localised, THz magnetic pulses in thermoelectric metamaterials. Excitation of bimetallic plasmonic resonators by ultrafast electromagnetic pulses, raises the electron energy and causes them to diffuse towards colder regions due to the thermoelectric effect. In addition, the resonator design and the excitation polarization create a situation in which electrons are forced to migrate in the azimuthal direction along the circumference of the ring, giving rise to a quasistatic magnetic field of up to 0:35 T, localized in an area with diameter of 70 nm. The time dynamics of the pulse generation process are controlled by electron energy relaxation to lattice through electron-phonon collisions, which lead to pulse duration of ~ 1:8 ps. I have demonstrated experimentally for the first time enhanced Faraday rotation in bimetallic single-layer metamaterials. The design of the unit cell resonator allows light confinement in the vicinity of the magneto optically active ferromagnetic metal which results in enhancement of the Faraday effect. Tailoring the size of the ferromagnetic component, which simultaneously controls the magneto-optical response and the dissipation losses in the system, results in a design which rotates the polarization azimuth of an incident electromagnetic wave by up to 1 mrad. I have demonstrated for the first time resonant absorption in single-layer Au/Ni photonic metamaterials and investigated its dependence on wavelength and polarization. A hybrid system consisting of materials that exhibit different levels of dissipation losses can be excited in ways which enable control over the spectral position, bandwidth and level of the optical absorption. The plasmonic modes mediating the metamaterial absorption are identified by a detailed computational analysis, which is in good agreement with the far-field experimental observations. I have fabricated for the first time single-layer, bimetallic ring resonator arrays consisting of noble and ferromagnetic metals. An optimized, multi-step electron beam lithography process has been developed in order to bring together, with sub-10 nm accuracy, the two metallic sectors and form 100 x 100 µm2 ring resonator arrays. I have developed a sensitive polarimeter apparatus to probe polarization rotation in metamaterial arrays. Following the principles of polarization modulation polarimetry, I have built a state of the art experimental setup that resolves angles as low as 10-5 radians in finite size, strongly scattering samples which have dimensions down to 50 x 50 µm2.

Résumé :
Over the last decades, many steps have been taken in the search for an effective method to reduce carbon dioxide to small organic molecules that can be used as fuel or building blocks for the chemical industry. The object of this work is to prepare two bimetallic electrocatalysts utilizing Cu combined with Au or In for the efficient and selective reduction of CO2 to CO, HCOOH and small fuels molecules. The copper-gold electrode is prepared through the electrodeposition of Cu on the surface of Au, using the underpotential deposition (UPD) technique to obtain a copper monolayer. The prepared electrode shows a high current density compared to Au electrode. Bimetallic metal oxides of CuInO2 is used as the precursor to prepare Cu-In alloys electrodes for electrochemical reduction of CO2. The electrocatalyst preparation is carried out using a thermal reducing treatment able to form different catalytic surfaces with different Cu-In alloys or single-phase metals. The best sample shows a high faradaic efficiency toward CO (71%) at the low overpotential of −0.8 V vs RHE. This study shows two examples of scalable and inexpensive preparation methods of bimetallic surfaces, which may use as selective electrocatalysts for the aqueous reduction of CO2.

Résumé :
The use of bimetallic weld joints is widespread in thermal and nuclear energy generation. It is evident from literature survey that the weld and ferritic steel HAZ region of bimetallic joints are prone to failures. The failures can be attributed to the generation of residual stresses in bimetallic welds. A typical bimetallic weld joint, representing a joint being tested for use in Indian Nuclear Reactors was fabricated between SA 516 Grade 65 and 304 austenitic stainless steel with and without the use of SS 309 L buttering layer. The buttering layer thickness was varied and surface and subsurface residual stresses were assessed using the hole drilling technique and neutron diffraction measurements. It was found that the SS 309 L buttering layer with thickness of around 6 mm employed in the bimetallic weld joint reduces the surface and sub-surface residual stresses in the critical region (ferritic steel HAZ) of the bimetallic weld joint.

Résumé :
In this work we investigate the use of NiCo bimetal/oxide as catalyst for hydrogen production from ethanol, with a focus on the deactivation pattern and the nature of the observed carbon deposition. It is well known that sintering and coke deposition during decomposition reaction significantly reduces the activity of the catalysts at higher temperature, by blocking the active sites of the catalysts. During ethanol decomposition reaction, the cleavage of C-C bond produces adsorbed *CH4 and *CO species that further decompose to form carbonaceous compounds. FTIR in-situ analysis was conducted between 50 to 400°C for all the catalysts to understand the reaction mechanism and product selectivity. Cobalt was found to be selective for aldehyde and acetate, whereas bimetallic Ni-Co was selective for the formation of CO at 400°C along with aldehyde. Complete conversion of ethanol was observed at 350°C and 420°C for NiCo and Cobalt respectively indicating an improvement in the rate of conversion when Ni was added to cobalt. The crystallinity, morphology and particle analysis of the used catalyst after reaction were studied using XRD, SEM and TEM respectively. The XRD shows the complete phase change of porous NiCoO2 to NiCo alloy and SEM indicates the presence of fibrous structure on the surface with 91.7 % of carbon while keeping 1:1 ratio of Ni and Co after the reaction. The detailed analysis of carbon structure using HRTEM-STEM shows the simultaneous growth of carbon nano fibers (CNFs) and multiwalled carbon nanotubes (MWCNTs) that were favored on larger and smaller crystallites respectively. Analysis of carbon formation on individual Co catalyst and bimetallic NiCo catalyst shows a clear difference in the initiation pattern of carbon deposition. Metallic Co nanoparticles were found to be more mobile where Co disperses along the catalysts surface, whereas NiCo nanoparticles were relatively less mobile, and maintained their structure.

Résumé :
Abstract Erosion widely exists in oil and gas production and transmission pipelines, which seriously affects the service life of pipelines. Ordinary carbon steel pipe can meet the strength and pressure of oil and gas transportation, but it has the disadvantages of poor erosion resistance, short service life and frequent replacement. The cost of using erosion resistant metal pipe is high, which is not suitable for comprehensive popularization and application. Bimetallic composite pipe includes outer layer and inner layer. It is formed by two different metals through a variety of processing technologies, which has the advantage that a single material does not have. It not only has the strength and toughness of the outer pipe, but also has the erosion resistance of the inner pipe. The service life of bimetallic composite pipeline can be 4–6 times longer than that of traditional carbon steel pipeline, and the manufacturing cost is relatively low, the service time is long, and it has good economy. Therefore, it is more and more widely used in oil and gas production and transportation. However, the common problem of bimetallic composite pipe is that the bonding interface between outer pipe and inner layer is not fully bonded and there has gaps. Or the interface binding force is not enough. When the composite pipe is eroded by the fluid in the pipe, the stress concentration at the interface will lead to the separation of the inner layer and the outer pipe, leading to the reduction of the service life of the pipe. Therefore, how to prepare the bimetallic composite pipe with good quality and strong erosion resistance has become an urgent problem to be solved. In this paper, carbon steel cemented carbide bimetallic composite pipe was prepared by electromagnetic heating through the application of centrifugal force and molten metal fluidity. The joint surface of the prepared bimetallic composite pipe was observed and analyzed, and the erosion test of the inner layer was carried out. The micro morphology of the erosion sample was observed and analyzed by shape analysis laser microscope. The erosion rate was accurately calculated according to the mass loss of the sample before and after erosion. The results show that the bimetallic composite pipe prepared by the above method has good interface bonding quality and no obvious defects. In the same erosion environment, the bimetallic composite pipe has stronger erosion resistance, lower erosion rate and higher service life than carbon steel pipe. Therefore, through the exploration of the preparation method of bimetallic composite pipe, this paper improves the preparation process of bimetallic composite pipe, improves the comprehensive mechanical properties and erosion resistance of bimetallic composite pipe, and promotes the application of bimetallic composite pipe in industrial production.

Résumé :
Gold (Au) and copper (Cu) materials and their combination exhibit the most of the main wanted properties in nanostructures. Nobel metals such as Au and Cu have important magnetic, electronic, optical, catalytic and thermal properties. Compared to monometallic clusters, bimetallic nanoclusters have more degrees of freedom and distinct properties due to the presence of two different metals. It is also well known that the shape, surface topography, segregation, mixing, ordering, energetic stability, and electronic structures of bimetallic nanoclusters may depend significantly on their composition. This affords greater opportunity to control their properties by modifying composition as well as size. In this work, we investigated magnetic and electronic properties for AuCu bimetallic core-shell structures and showed that the CuAu coreshell can have a half-metal property through chemical composition modification. Half-metallic ferromagnets attract increasing research interest as potential materials for spintronic device applications.
