A series of spherical activated carbons(SACs)with different pore structures were prepared from chloromethylated polydivinylbenzene by ZnCl2 activation.The effec
Four kinds of lanthanide ions(Sm3+,Yb3+,Eu3+,La3+) as an additive were added into the aqueous solution containing methanol,respectively,and their effects on met
Several borohydride reagents:sodium borohydride,sodium cyanoborohydride,soudium acetoxyborohydride and soudium triacetoxyborohydride were screened,respectively,
Two novel polymeric complexes, [Gd(H5TCAS)(H2O)7]·4H2O 1 and [Gd(H5TCAS)(CH3COCH3)(H2O)6]·6H2O 2 (H4TCAS = p-sulfonatothiacalix[4]arene), have been synthesize
Many of the drugs currently used in medical practice are racernates.The enantiomers of a racemic drug differ in pharrnacodynamics and/or pharmacokinetics,thus i
