The rate constants of reactions between the SO4·- radical and some common anions in atmospheric aqueous droplets e.g. Cl-,NO3-, HSO3- and HCO3- were determined
A new nanometer material, nano-Al2O3 with carbon fibre as the carrier, was employed for the removal of Cd with low concentrations from polluted water. The chara
A novel macrolactonization method was developed using a chiral β-lactam as the template. This novel method features that the macrocyclization is simultaneously
A novel triterpenoid, D:B-friedoursane-3α, 16α-dihydroxy-7α, 8α-epoxy-5(10)-ene,named petatrichol A, was isolated from the roots of Petasites tricholobus Fr
A PES-PC(polyethersulfone-polycarbonate) multi block random copolymer was synthesized with two oligomers, polyethersulfone and polycarbonate. The effects of the
A new approach to produce superfine WC-Co powder by direct reduction and carbonization is proposed. Water-soluble salts containing W and Co were used as raw mat
A new coupled finite element formulation is proposed to calculate a conformation tensor model in two complex flows: a planar contraction flow and a planar flow
