Completely green synthesis of colloid Adams' catalyst α-PtO2 nanocrystals and derivative Pt nanocrystals with high activity and stability for oxygen reduction.

We report a first solution strategy for controlled synthesis of Adams' catalyst (i.e., α-PtO(2)) by a facile and totally green approach using H(2)PtCl(6) and water as reactants.

Selective synthesis of Fe7Se8 polyhedra with exposed high-index facets and Fe7Se8 nanorods by a solvothermal process in a binary solution and their collective intrinsic properties.

Fe(7)Se(8) polyhedra with high-index facets and Fe(7)Se(8) nanorods can be selectively synthesized by a solvothermal reaction in a mixed solvent of diethylenetriamine (DETA) and deionized water (DIW). It is found that the morphologies of Fe(7)Se(8) nanocrystals can be effectively controlled by adjusting the volume ratio of DETA and DIW. The unusual polyhedral crystals are bounded by two {001} and twelve {012} facets.

[Clinical study on the treatment of male immune infertility by Huzhangdanshenyin].

Objective: To investigate the efficacy of the Chinese medicine Huzhangdanshenyin on male immune infertility, and provide an effective therapy for this disease.

Methods: Ninety men with immune infertility were selected as the research subjects and randomly divided into two groups, 60 in the treatment group, treated by Huzhangdanshenyin, and the other 30 in the control, treated by prednisone, both for 3 months. The improvement of clinical symptoms, immunologic indexes (antisperm antibodies in serum and seminal plasma) and sperm indexes (semen liquefied duration, motility, viability, density and abnormal morphology rate) were observed and the results analyzed.
