70th Annual Meeting of the International Society of Electrochemistry, Aug 2019, Durban, South Africa

International audience; Due to strain and ligand effects, the simultaneous presence of concave and convex surfaces and their highly-defective nanostructure (atomic vacancies, grain boundaries), highly defective hollow PtNi/C electrocatalysts have pro

New Data on the Stability of bcc Iron in the Earth Inner Core

Autor: Belonoshko, A. B., Ahuja, R., Le Bacq, O., Johansson, B.

Publikováno v: AGU Fall Meeting Abstracts
AGU Fall Meeting Abstracts, Dec 2001, San Fransisco, United States

International audience; A comparison between recent experimental [1] and theoretical [2] data on melting of Xe at high pressure has demonstrated that the close-packed structure to bcc structure transition might be misinterpreted as a melting transiti
