A simple and convenient procedure for the preparation of amines from aldehydes and ketones with sodium borohydride activated by silica chloride as a catalyst un
Since time-course microarray data are short but contain a large number of genes, most of statistical models should be extended so that they can handle such stat
Lower groups of coal seams are presently being mined in the Yanzhou coal mining area. We need to evaluate the risk from water-inrush from coal floors in order t
A series of Na-W-Mn-Zr/SiO_2 catalysts promoted by different contents of S or/and P were prepared and their catalytic performance for oxidative coupling of meth
Sea-urchin-like ZnO nanomaterials were successfully synthesized by decomposition of zinc acetate precursor in the presence of sodium hydroxide and ethylene glyc
A crystallographic homogenization method is proposed and implemented to predict the evolution of plastic deformation induced texture and plastic anisotropy (ear
