Electrochemical deposition of Co - Sb thin films and nanowires / Dat V. Quach in Industrial & engineering chemistry research, Vol. 49 N° 22 (Novembre 2010) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 49 N° 22 (Novembre 2010) . - pp 11385–11392 Titre : Electrochemical deposition of Co - Sb thin films and nanowires Type de document : texte imprimé Auteurs : Dat V.

Groza, Auteur Année de publication : 2011 Article en page(s) : pp 11385–11392 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Electrochemical  Nanowires Résumé : Co−Sb thin films and nanowires were grown on gold-coated polymer templates by electrochemical deposition under different potentiostatic conditions from −0.8 to −1.0 V vs Ag/AgCl. The growth of nanowires was 3D and went through several growth stages starting from the gold-coated wall. Overgrowth of nanowires out of the porous template did not produce a fully dense film; instead, Sb-rich columnar structures (mushroom caps) were developed and connected by Co-rich needle-like structures. Compared to nanowires, the mushroom caps had a lower content of Co. With a more negative deposition potential, the content of Co in the nanowires and the mushroom caps increased. A composition of Co:Sb = 1:3 in nanowires was obtained at a constant deposition potential of −0.965 V.

Solar energy storage methods / Yu Hou in Industrial & engineering chemistry research, Vol. 50 N° 15 (Août 2011) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 50 N° 15 (Août 2011) . - pp. 8954–8964 Titre : Solar energy storage methods Type de document : texte imprimé Auteurs : Yu Hou, Auteur ; Ruxandra Vidu, Auteur ; Pieter Stroeve, Auteur Année de publication : 2011 Article en page(s) : pp. 8954–8964 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Solar  energy Résumé : Solar energy can provide an abundant source of renewable energy (electrical and thermal). However, because of its unsteady nature, the storage of solar energy will become critical when a significant portion of the total energy will be provided by solar energy. In this paper, current solar energy storage technologies are reviewed. Storage methods can be classified into categories according to capacity and discharge time. New developments in solar energy storage require advances in chemical engineering and materials science. Life cycle assessment (LCA) is an important tool to evaluate energy consumption and environmental impact of renewable energy processes. LCAs of some of the storage methods are reviewed. It is important to note that, while using renewable energy sources such as solar power, storage methods based on nonrecyclable materials or methods that consume significant amounts of energy may undermine the effort to reduce energy consumption.
