Bimetallic nanocrystals consisting of two distinct metals such as Pd and Pt are attractive for a wide variety of catalytic and electrocatalytic applications as they can exhibit not only a combination of the properties associated with both metals but also enhancement or synergy due to a strong coupling between the two metals. With Pd as the base metal, many methods have recently been demonstrate...

An understanding of the nucleation and growth mechanism of bimetallic nanoparticles in solvothermal synthesis is important for further development of nanoparticles with tailored nanostructures and properties. Here the formation of PtRu alloy nanoparticles in a solvothermal synthesis using metal acetylacetonate salts as precursors and ethanol as both the solvent and reducing agent has been studi...

Surface enhanced fluorescence (SEF) utilizes the local electromagnetic environment to enhance fluorescence from the analyte on the surface of a solid substrate with nanostructures. While the detection sensitivity of SEF is improved with the development of nano-techniques, detection of multiple analytes by SEF is still a challenge due to the compromise between the high enhancing efficiency and b...

Die less explosive forming of circular plates is one of the most useful methods in the industries especially chemical applications. Manufacturing of large vessel's head, multilayer rings and some parts of heat exchangers are the example of applying this method. Many theoretical and experimental researches about examining the explosive forming of simple and single layer plate have been done. The...

Bimetallic oxalates are molecule-based magnets with transition-metal ions M(II) and M(')(III) arranged on an open honeycomb lattice. Performing a Holstein-Primakoff expansion, we obtain the spin-wave spectrum of antiferromagnetically coupled bimetallic oxalates as a function of the crystal-field angular momentum L(2) and L(3) on the M(II) and M(')(III) sites. Our results are applied to the Fe(I...

Two-dimensional assemblies of Au-Pt bimetallic nanoparticles are generated in situ on polyethyleneimmine (PEI) silane functionalized silicon and indium tin oxide (ITO) coated glass surfaces. Atomic force microscopy (AFM), UV-Visible spectroscopy, and electrochemical measurements reveal the formation of core-shell structure with Au as core and Pt as shell. The core-shell structure is further sup...

Bimetallic dichlorotitanium complexes, {2,6-[eta(5)-2,5-Me2C5H2](2)-4-R-C6H2N-microN}{Ti(IV)Cl2}2 (, R=Me; , R=F) and 4,4'-A[{2-(eta(5)-2,3,5-Me3C5H)C6H3NC6H11-kappaN}Ti(IV)Cl2]2 (, A=CH2; , A=O; , A=ortho-C6H4) are prepared via a key step of the Suzuki-coupling reaction of 2-dihydroxyboryl-3-methyl-2-cyclopenten-1-one () with dibromo-compounds. The solid state structure of was determined by X-...

Single metal-organic frameworks (MOFs), constructed from the coordination between one-fold metal ions and organic linkers, show limited functionalities when used as precursors for nanoporous carbon materials. Herein, we propose to merge the advantages of zinc and cobalt metals ions into one single MOF crystal (i.e., bimetallic MOFs). The organic linkers that coordinate with cobalt ions tend to ...

Silver nanoparticles are extensively used due to their chemical and physical properties and promising applications in areas such as medicine and electronics. Controlled synthesis of silver nanoparticles remains a major challenge due to the difficulty in producing long-term stable particles of the same size and shape in aqueous solution. To address this problem, we examine three strategies to st...
