Abstract:
Bimetallics are emerging as important materials that often exhibit distinct chemical properties from monometallics. However, there is limited access to homogeneously alloyed bimetallics because of the thermodynamic immiscibility of the constituent elements. Overcoming the inherent immiscibility in bimetallic systems would create a bimetallic library with unique properties. Here, we present a nonequilibrium synthesis strategy to address the immiscibility challenge in bimetallics. As a proof of concept, we synthesize a broad range of homogeneously alloyed Cu-based bimetallic nanoparticles regardless of the thermodynamic immiscibility. The nonequilibrated bimetallic nanoparticles are further investigated as electrocatalysts for carbon monoxide reduction at commercially relevant current densities (>100 mA cm−2), in which Cu0.9Ni0.1 shows the highest multicarbon product Faradaic efficiency of ~76% with a current density of ~93 mA cm−2. The ability to overcome thermodynamic immiscibility in multimetallic synthesis offers freedom to design and synthesize new functional nanomaterials with desired chemical compositions and catalytic properties.

Abstract:
Carbon black supported Pd-Mo bimetallical nanoparticles are prepared by Strong Electrostatic Adsorption (SEA) method. A series of Pd-Mo catalysts were prepared by selective deposition of the [Pd (NH3)4]+2cationion onto the supported MoO3phase. The prepared materials are characterized by N2-BET, powder XRD and STEM. The results showed that good dispersion of bimetallic nanoparticles on the carbon support is observed from STEM images. Oxygen reduction measurements performed by linear sweep voltammetry indicat the good catalytic activity of Pd-Mo by SEA compared to dry impregnation (DI) bimetallic catalysts since the SEA technique produced more well dispersed and intimately designed bimetallic particles after reduction.

Abstract:
This article analyzes the stability of bimetallism for countries operating in integrated bullion markets that enact different legal ratios. I articulate a new theoretical framework to demonstrate that two countries can both be bimetallic only if they coordinate their legal ratios. The theoretical framework is applied to the mid-eighteenth century when London's legal ratio was 3.8 percent higher than that of Amsterdam. I find that Amsterdam was effectively on the bimetallic standard, whereas London was on a de facto gold standard.

Abstract:
The controlled formation of mixed-metal bimetallics was realised through use of a fac-[Re(CO)3(N,N′-bpy-P)Cl] complex bearing an exogenous 2,4,6-trioxa-1,3,5,7-tetramethyl-8-phosphaadamantane donor at the 5-position of the bpy. The introduction of gold, silver, and rhodium with appropriate secondary ligands was readily achieved from established starting materials. Restricted rotation about the C(bpy)-P bond was observed in several of the bimetallic complexes and correlated with the relative steric bulk of the second metal moiety. Related chemistry with the 6-substituted derivative proved more limited in scope with only the bimetallic Re/Au complex being isolated.

Abstract:
This article attempts to provide a new view of how the bimetallic standard was maintained before 1873 and how it came to change into a monometallic gold standard between 1870 and 1880. The conventional view that the gold standard emerged out of the contradictions of bimetallism is not persuasive. Instead, this article claims that bimetallism might have survived and provides an alternative explanation of the emergence of the gold standard. Political and historical factors proved essential in precipitating the uncoordinated emergence of the international gold standard.

Abstract:
Raney nickel shows potential as an electrocatalyst for the oxygen evolution reaction (OER). However, the catalytic activity of Raney nickel varies with its properties. These properties are related to the composition of the bimetallic precursor used to synthesise Raney nickel. The bimetallic precursor consists of a combination of bimetallic phases. Various studies have been done on the well-known bimetallic phases, namely, Ni2Al3, NiAl and NiAl3. However, to get a more comprehensive understanding of the influence of the bimetallic precursor on the properties of Raney nickel, a larger spectrum of bimetallic phases needs to be evaluated. In this study, the Site Occupation Disorder (SOD) program was used to build solid-state structures (bimetallic phases) with various Ni1-xAlx bimetallic ratios. These Ni1-xAlx bimetallic phases were evaluated, and unique configurations for each Ni1-xAlx bimetallic ratio were obtained. The unique configurations were geometrically optimised using the General Utility Lattice Program (GULP) at 0K. These optimised unique configurations were thermodynamically evaluated over a range of 0.1K – 1200K, and the most stable configurations with a probability higher than 10% were identified. This study found that the stable non-homogeneous configurations fall within a range of 20% - 80% Ni content. A weight average combination of these configurations of the bimetallic phases will produce a non-homogeneous precursor with an average Ni content of 20% - 80%, which is in close agreement with experimental results. The approach in this study enables researchers to obtain a larger, repeatable spectrum of bimetallic phases for the investigation of Raney nickel precursors.

Abstract:
The alkaline medium oxygen reduction reaction (ORR) activities of Ag–Cu bimetallic nanoparticles (BNPs), consisting of neighboring Ag and Cu domains, were studied and compared with those of pure Ag and Cu nanoparticles prepared by the same polyol route. Three variations of Ag–Cu BNPs viz. Ag–Cu (4:1), Ag–Cu (2:1), Ag–Cu (1:1) BNPs were considered. The electrocatalytic performances of these nanoparticles were investigated by using different techniques, such as cyclic voltammetry (CV) and linear sweep voltammograms (LSV). The Ag–Cu bimetallics demonstrated synergistic ORR electrocatalytic activity compared to pure Ag or Cu. Optimum values of these parameters were observed for Ag–Cu (4:1) BNPs. According to LSV, the reduction peak position is at lower applied potential and showed higher intensity for the Ag–Cu (4:1) as compared to Ag–Cu (2:1) and Ag–Cu (1:1) BNPs. Density Functional Theory (DFT) calculations show that charge transfer from Cu to Ag (in the bimetallic nanoparticles) results in their stronger oxygen interaction and water activation properties relative to that of pure Ag nanoparticles.

Abstract:
The stainless-clad bimetallic steel not only has strong corrosion resistance, but also has low production cost and high strength. Compared with a single stainless steel or ordinary carbon steel material, the strengths of stainless-clad bimetallic steel are obvious, such as a wider market prospect and better material properties. Presently, the stainless-clad bimetallic steel has been successfully applied in the maintenance system of railway steel bridge panels and high-rise building curtain wall. In order to promote the application of stainless-clad bimetallic steel in structural engineering, this paper systematically introduces the manufacturing process of the stainless-clad bimetallic steel, including production technology and welding technology. In addition, the mechanical properties such as corrosion resistance and composite interface properties are studied and analyzed. The research of the stainless-clad bimetallic steel has important economic significance, social significance and strategic value. It is hoped that results from this paper can provide reference for researches on the stainless-clad bimetallic steel in the further.

Abstract:
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.

Abstract:
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.

Abstract:
Bimetallic Catalysis is an emerging field of study that uses two metals to cooperatively perform organic transformations. These metals can serve to activate or bind substrates in order to increase the rate and selectivity of reactions. This work first describes the synthesis and utilization of six new chiral, titanium-containing phosphinoamide ligands. These Lewis acidic ligands withdraw electron density from an active palladium center to induce chirality and increase the rate of allylic amination of hindered, secondary N-alkyl amines. X-ray quality crystals were grown for each ligand and completed the allylic amination of hindered secondary amines in minutes whereas other non-titanium-containing ligands produced trace product. Although enantioselectivity was low initially, through a dynamic kinetic resolution enantioselectivity was increased over time, reaching 53% enantioselectivity. The second type of bimetallic catalysis discussed is dinuclear Pd(II) and Pd(I) catalysis. These dimers were built on a 2-phosphinoamide ligand scaffold and present interesting molecular structure and unique reactivity. These dimers were found to perform tandem arylketone coupling to produce disubstituted naphthalene products under oxidative conditions. It is proposed that the Pd(II) dimer undergoes oxidative addition to produce a Pd(III) dimer which subsequently produces an aryl-ketone intermediate. This process is made possible by the cooperativity of the two palladium centers which enable the formation of a Pd(III) dimer, circumventing the need for the high energy Pd(IV) oxidation state. Oxidative conditions then allows coupling and cyclization of a second ketone to form the naphthalene product.

Abstract:
Polymer electrolyte fuel cells (PEFCs) have emerged as a promising renewable emission-free technology to solve the worldwide increasing demand for clean and efficient energy conversion. Despite large efforts in academia and automotive industry, the commercialization of PEFC vehicles still remains a great challenge. Critical issues are high material costs, insufficient catalytic activity as well as longterm durability. Especially due to the sluggish kinetics of the oxygen reduction reaction (ORR), high Pt loadings on the cathode are still necessary which leads to elevated costs. Alloys of Pt with other less precious metals (Co, Ni, Fe, Cu, etc.) show improved ORR activities compared to pure Pt catalysts. However, state-of-the-art carbon-supported catalysts suffer from severe Pt and carbon corrosion during the standard operation of PEFCs, affecting their reliability and long-term efficiency. Multimetallic aerogels constitute excellent candidates to overcome these issues. Due to their large open pores and high inner surface areas combined with electrical conductivity, they are ideal for applications in electrocatalysis. In addition, they can be employed without any catalyst support. Therefore, the fabrication of bimetallic Pt-M (M=Ni, Cu, Co, Fe) aerogels for applications in fuel cell catalysis was the focus of this thesis. Based on a previously published synthesis for Pt–Pd aerogels, a facile one-step procedure at ambient conditions in aqueous solution was developed. Bimetallic aerogels with nanochain diameters of as small as 4 nm and Brunauer-Emmett-Teller (BET) surface areas of up to 60 m2/g could be obtained. Extensive structure analysis of Pt–Ni and Pt–Cu aerogels by powder X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), X-ray absorption spectroscopy (XAS), scanning transmission electron microscopy coupled with energy-dispersive X-ray spectroscopy (STEM-EDX) and electrochemical techniques showed that both metals were predominantly present in their metallic state and formed homogeneous alloys. However, metal (hydr)oxide byproducts were observed in aerogels with higher contents of non-precious metal (>25 %). Moreover, electronic and geometric structures were similar to those of carbon-supported Pt alloy catalysts. As a result, ORR activites were comparable, too. A threefold improvement in surface-specific activity over Pt/C catalysts was achieved. The mass-specific activites met or exceeded the U.S. Department of Energy (DOE) target for automotive PEFC applications. Furthermore, a direct correlation between non-precious metal content in the alloy and ORR activity was discovered. Aerogels with nonprecious metal contents >25% turned out to be susceptible to dealloying in acid leaching experiments, but there was no indication for the formation of extended surface structures like Pt-skeletons. A Pt3Ni aerogel was successfully employed as the cathode catalyst layer in a differential fuel cell (1 cm2), which is a crucial step towards technical application. This was the first time an unsupported metallic aerogel was implemented in a PEFC. Accelerated stress tests that are usually applied to investigate the support stability of fuel cell catalysts revealed the excellent stability of Pt3Ni alloyed aerogels. In summary, the Pt alloy aerogels prepared in the context of this work have proven to be highly active oxygen reduction catalysts with remarkable stability.

Abstract:
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.

Abstract:
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.

Abstract:
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.
