Carbon-silicon nanowires and
cool biofuel catalyst
* Yi Cui's group
at Stanford has advanced recent
work on silicon core-shell nanowire battery electrodes by replacing
the crystalline silicon cores with cheaper, sturdier carbon. See Carbon-Silicon
Core-Shell Nanowires as High Capacity Electrode for Lithium Ion Batteries,
Nano Letters, online August 5, 2009.
* A tungsten-based catalyst allows fructose to be converted
to a biofuel precursor at room temperature and ambient pressure. See
Selective
Conversion of Fructose to 5-Hydroxymethylfurfural Catalyzed by Tungsten
Salts at Low Temperatures, ChemSusChem, online July 31,
2009.
