ABSTRACT This paper delves into the phenomenon of catch‐up innovation in China, examining it through institutional framework local government competition. Our theoretical modeling indicates that order to perform well performance appraisals and obtain a greater probability promotion, governments tend implement excessive policy incentives, ultimately sparking an intense competition for among regions China. Empirical analyses corroborate effectiveness supportive policies fostering innovation....
Special carbon encapsulated Fe core-shell nanoparticles with a size range of 15–40 nm were successfully prepared via confined arc plasma method. The composition, morphology, microstructure, specific surface area, particle the product by this process characterized X-ray diffraction (XRD), transmission electron microscopy (TEM), high resolution (HRTEM), energy dispersive spectrometry (XEDS) and BET N 2 adsorption. experiment results shown that clear structure, core particles is body centered...
Helical structure ZnS were successfully prepared via solvothermal method by the reaction of zinc acetate and sodium sulphide. The composition, morphology, microstructure sample characterized X-ray diffraction (XRD), high resolution transmission electron microscopy (HRTEM), corresponding selected area (SAED) energy spectrum (EDS). experiment results show that is 1-D hexagonal crystal grows along [002] direction, helical structure, with lengths in range 100-200 nm, diameter about 5-15 pitch 20nm.
