The title copolymers and their water soluble carboxylates were synthesized from methyl acrylate and cinchonine, quinine in CHCl 3, respectively, using azo-bis- isobutyroni- trile as initiator. The four compounds as chiral amine ligands being reacted with dimethylglyoximatocobalt(Ⅱ) gave four complexes, which were used for catalytic asymmetric hydrogenation of acetamidocinamic acid, giving considerably possitive results. 展开更多

The development of hydrogen redox electric power generators for infinite cruising range electric vehicles represents a true technological breakthrough. Such systems consist of a polymer electrolyte membrane hydrogen electrolytic cell equipped with an electrostatic-induction potential-superposed water electrolytic cell that provides a stoichiometric H2-O2 fuel mixture during operation of the vehicle. This generator functions with zero power input, zero matter input and zero emission due to the so-called "zero power input" electrostatic-to-chemical energy conversion occurring in the electrolytic cell. Here, theoretical simulations were performed to verify the target performance of such generators, assuming a pair of FC (fuel cell) and electrolytic cell stacks, both of which are commercially available. 展开更多

Polar acrylic monomers show low abundance by gas chromatography. Because of this, a home-made pyrolysis liquid chromatographic injector by means of cryogenic-focussing is developed to determine the presence and concentration of hydroxyl and carboxyl functional monomers present in water- and solvent-borne acrylics. We have shown the prove-of-principle of using cryogenic-focussing for UPLC (pyrolysis-ultra-performance liquid chromatography) injection. 展开更多

As an important energy carrier in terms of carbon neutrality,green hydrogen produced by water electrolysis using renewable electricity has attracted worldwide attention.The polymer electrolyte water electrolyzer(PEWE)has the potential to be a mainstay in the green hydrogen market in the future because of its superior performance.However,the development of PEWE is constrained by the slow progress of the membrane electrode assembly(MEA),which is an essential component of PEWE and largely determines the cost and performance of the system.Therefore,the MEA must be optimized from the aspects of reducing cost and improving performance to promote the development of PEWEs.In this review,we first discuss the recent progress of the materials and design strategies of MEA,including the cost,activity,and stability of catalysts,distribution and thickness of ionomers,and ion transport efficiency of ion exchange membranes(IEMs).Then,the effects of all components and interlayer interfaces on the ions,electrons,and mass transfer in MEA and,consequently,the performance of PEWE are analyzed.Finally,we propose perspectives on developing MEA by optimizing the catalyst activity and stability of IEM,interface contact between adjacent components,and evaluation methods of performance. 展开更多
