CuP@CoO core-shell heterostructure with synergistic effect for highly efficient hydrogen evolution.

The sluggish charge transfer and poor intrinsic activity are the obstacles that limit the development for electrocatalysts on hydrogen evolution. A novel core-shell heterostructure composed of CuP nanowires with supported CoO nanosheets was synthesized. Owing to numerous active sites and synergistic effect, the as-prepared CuP@CoO was highly efficient for hydrogen evolution and outperformed the single component.

Heterostructure of ultrafine FeOOH nanodots supported on CoAl-layered double hydroxide nanosheets as highly efficient electrocatalyst for water oxidation.

The supported and dispersed ultrafine active species for electrocatalytic water oxidation are quite promising for the high intrinsic activity. A novel heterostructure of ultrafine FeOOH nanodots with an average size of 2.3 nm supported on CoAl-LDH nanosheets, is constructed by a facile method under ambient conditions.

[Pharmacokinetics of praziquantel injection in healthy buffaloes].

To investigate the pharmacokinetics and relative bioavailability of praziquantel injection in buffaloes in contrast to praziquantel tablet. A single oral administration of praziquantel tablet at a dose of 20 mg/kg or intramuscular administration of praziquantel injection at a dose of 10 mg/kg was performed in six healthy adult buffalos according to a twoperiod crossover design. The praziquantel concentration in plasma was determined by a high performance liquid chromatography (HPLC) method.
