Cobalt (Co)-modified brownmillerite KBiFe2O5 (KBFO; [KBiFe2(1−x)Co2xO5 (x = 0, 0.05)]) polycrystalline is synthesized following the solid-state reaction route. Rietveld refinement of X-ray diffraction data confirmed the phase purity of KBFO and KBiFe1.9Co
随着现代社会的发展,电视新闻工作者的工作内容不仅是为广播站服务,还需要在一些媒体上面进行一些新闻的发布以及一些其他的工作,但是按照以前的工作模式很难完成这样的工作,因此媒体融合的重要性就显现出来了.
The microstructural properties and electrochemical performance of zinc (Zn) sacrificial anodes during strain-induced melt activation (SIMA) were investigated in this study. The samples were subjected to a compressive ratio of 20%–50% at various temperatur
MnO2/biomass carbon nanocomposite was synthesized by a facile hydrothermal reaction. Silkworm excrement acted as a carbon precursor, which was activated by ZnCl2 and FeCl3 combining chemical agents under Ar atmosphere. Thin and flower-like MnO2 nanowires
Reaction-bonded B4C–SiC composites are highly promising materials for numerous advanced technological applications. However, their microstructure evolution mechanism remains unclear. Herein, B4C–SiC composites were fabricated through the Si-melt infiltrat
3Y-TZP/3wt% Al2O3 powder was coated with varying amounts of BN using the urea and borate reaction sintering method, and then multiphase ceramics were prepared by hot pressing sintering. The micro-topography and the compositional analysis of synthesized ce
Functionalized ionic liquids (FILs) as extractants were employed for the separation of tungsten and molybdenum from a sulfate solution for the first time. The effects of initial pH, extractant concentration, metal concentrations in the feed were comprehen
基于我国经济的急速转型和各项政策调整供需关系的改革,政府职能在逐步转变中持续深入,各层级的政府不仅仅在经济发展进行调整,同时在资源配置中优化.基层税务承担各项税法以及税收的落实和执行工作,通过税务方式来影响整体经济发展,可以说越是基层税务对国家经济核心作用就越强.因此,对基层税务加强预算绩效管理是必须环节,也是对现有税务职能持续优化的必然选择.但是,在实际进行预算绩效管理中,基层税务还存在很多问题,需要通过现状分析其原因,提出可改善的意见,促进基层税务更好服务于社会经济发展中.
近年来,随着我国城市化快速发展,在城市建设中违法建筑物屡见不鲜,违法建筑在设计和地理位置上都会影响到城市的发展、城市的形象.在城市快速发展中,社会对于城区违法建筑问题关注度更高,还有些地区纷纷出台了一系列的治理办法,从政策到法律形成了一套严谨而高效的城市开发建设制度.
在个人工作中,人事档案不仅是重要的来源证明,而且与福利待遇、选拔任用密切相关.加强人事档案管理,全面、有效地实施人事档案管理,对全社会及个人发展具有重要意义.
