Small molecule-assisted synthesis of carbon supported platinum intermetallic fuel cell catalysts

Nature Communications, 2022
Synthesis of small sized Pt intermetallic catalysts remains challenging. Herewith authors prepared 18 binary Pt intermetallic compounds with small particle size by molecule-assisted synthesis strategy to in-situ form the heteroatom-doped carbon shell.

The Role of Intermetallic Compounds in Controlling the Microstructural, Physical and Mechanical Properties of Cu-[Sn-Ag-Cu-Bi]-Cu Solder Joints

Scientific Reports, 2019
A lead-free Sn-2.5Ag-0.7Cu base solder with different weight percentages of bismuth (0, 1, 2.5, 5) was used. Thermal properties, microstructure, wettability and mechanical properties were investigated.

Electron Transfer in Intermetallic Compounds [PDF]

Proceedings of the National Academy of Sciences, 1950
In our discussions of the electronic structure of intermetallic compounds during the last three years brief mention has been made from time to time of the phenomenon of electron transfer [1-3]. The interpretation of the observed interatomic distances in many metallic phases seems to require the assumption that electron transfer has taken place; an ...

The intermetallic compound BaAgBi

Acta Crystallographica Section E Structure Reports Online, 2002
BaAgBi was obtained as a by-product when Ba [rod, Alfa–Aesar (99.99%)], Ag [powder, −100 mesh, Alfa–Aesar (99.999%)], and Bi [powder, −100 mesh, Alfa–Aesar (99.999%)] were loaded into a tantalum tube (Nobel-Met. Ltd, >99.85%, 0.375 in. OD) in a 1:1:2 molar ratio in an Ar-filled glovebox.

Selective Hydrogenation of Cinnamaldehyde over Co-Based Intermetallic Compounds Derived from Layered Double Hydroxides

ACS Catalysis, 2018
Selective hydrogenation of unsaturated carbonyl compounds plays a key role in the production of fine chemicals and pharmaceutical agents. In this work, two kinds of intermetallic compounds (IMCs: CoIn3 and CoGa3) were prepared via structural topotactic ...

The Crystal Orbital Hamilton Population (COHP) Method as a Tool to Visualize and Analyze Chemical Bonding in Intermetallic Compounds

, 2018
Recognizing the bonding situations in chemical compounds is of fundamental interest for materials design because this very knowledge allows us to understand the sheer existence of a material and the structural arrangement of its constituting atoms. Since

Zero Thermal Expansion in Magnetic and Metallic Tb(Co,Fe)2 Intermetallic Compounds.

Journal of the American Chemical Society, 2018
Due to the advantage of invariable length with temperatures, zero thermal expansion (ZTE) materials are intriguing but very rare especially for the metals based compounds. Here, we report a ZTE in the magnetic intermetallic compounds of Tb(Co,Fe)2 over a
