Hydrogen oxidation on ordered intermetallic phases of platinum and tin - A combined experimental and theoretical study
(2013-03-15)
Hydrogen oxidation on the surfaces of the intermetallic compounds Pt 3Sn, PtSn and PtSn2 has been studied by the rotating disc electrode technique. Pt3Sn and PtSn were found to be good catalysts, about as good as Pt, while ...
Some properties of intermetallic compounds of Sn with noble metals relevant for hydrogen electrocatalysis
(Elsevier B.V., 2014-01-10)
Using density functional theory and a model developed in our own group, we have investigated the suitability of three intermetallic compounds - AuSn, PdSn, and PtSn - as electrode materials for hydrogen oxidation in fuel ...

Obtaining NiAl intermetallic compound using different milling devices
(Elsevier Science BVAmsterdam, 2012)
NiAl intermetallic compound was synthesized by mechanical alloying technique in planetary and attritor mills. The starting powders consisted of elemental mixtures of Ni and Al at Ni50Al50(at%) composition. In the planetary ...
Synthesis and Characterization of Ordered Intermetallic Nanostructured PtSn/C and PtSb/C and Evaluation as Electrodes for Alcohol Oxidation
(Springer, 2010-09-01)
Ordered intermetallic compounds of Pt-based metal electrocatalysts have been recently proposed as very efficient anode materials for reactions involved in low temperature fuel cells. In this work, supported ordered ...
Ordered Intermetallic Nanostructured PtSb/C for Production of Energy and Chemicals

Electron theoretical investigation of the stability of the B2-TiFe compound
(ELSEVIER SCIENCE SA, 2009)
The metastable phase diagram of the BCC-based ordering equilibria in the Ti-Fe system has been calculated using a truncated cluster expansion, through the combination of FP-LAPW and cluster variation method (CVM) in the ...
Cohesive properties of (Cu,Ni)-(In,Sn) intermetallics: Database, electron-density correlations and interpretation of bonding trends
(Pergamon-Elsevier Science Ltd, 2016-01)
This paper presents a systematic and comparative study of the composition and volume dependence of the cohesive properties for a large group of Me-X intermetallic phases (IPs) with Me=Cu,Ni and X=In,Sn, which are of interest ...
Study of elastic properies of Ti3Al intermetallic compound using the ab initio calculation
(2014)
The elastic properties of a Ti3Al intermetallic compound were studied using full potential (FP LAPW ) with the APW+lo method. The FP-LAPW is among the most accurate band structure calculations currently available and is ...
