Resumen:
ESTE PAPER HA SIDO PROMOVIDO A "HOT PAPER" EN PCCP. Dear Professor Dr Leiva (Paper Ref.: B801838C) Title : Nanothermodynamic considerations and computer simulations on the formation of core-shell nanoparticles under electrochemical conditions Due to the excellent referee reports that your paper received, we would like to promote your paper as a "hot article". Such articles are considered for our "hot articles" section on our web site, or used in future promotional material or press releases for PCCP.  We would be grateful if you could answer a few questions on your article for us: these would be used in the promotion of your article, and we will base our decision on the appropriate means of promotion on these responses. Yours sincerelyMadelaine ChapmanDr Madelaine Chapman, Assistant Editor, PCCP & Faraday Discussions Royal Society of Chemistry, Thomas Graham House, Science Park, Cambridge, CB4 0WF, UK Tel +44 (0)1223 432298, Fax +44 (0)1223 420247 Faraday Discussions - Exciting debate on hot topics in physical chemistry. http://www.rsc.org/Publishing/Journals/fd/index.asp Abstract del Trabajo: We report on thermodynamic modeling and computer simulations on the electrochemical generation of metallic and bimetallic nanoparticles (NPs) by means of quenched molecular dynamics (QMD). The present results suggest that the spontaneous formation of core-shell NPs depends on several factors, i.e. size and shape of the core, chemical composition of the system, and under/over saturation conditions. Homo and heteroatomic prototypical systems were considered. The former systems were Au and Pt. The latter were Ag(core)/Au(shell), Pt(core)/Au(shell), Au(core)/Ag(shell) and Au(core)/Pt(shell).
