Polyaniline(Pani) film was applied onto AZ91 magnesium alloy in aqueous solutions containing oxalic acid and aniline monomer by cyclic voltammetry(CV) technique, which then was characterized by means of IR and SEM technique. Furthermore, the corrosion performance of the coating was evaluated in 3.5% Na Cl solution thr…
High performance fibers impregnated by shear thickening fluids(STFs) have been recognized as a kind of latent stab-resistant materials. In our work, the rheological properties of various nano-silica particles in diffierent carriers were first investigated, some of which showed the typical characteristic of shear thick…
Cardiotoxicity as a result of cancer treatment is a novel and serious public health issue that has a significant impact on a cancer patient’s management and outcome.The coexistence of cancer and cardiac disease in the same patient is more common because of aging population and improvements in the efficacy of antitumor…
AC adsorbent is prepared respectively with HNO3,high pressure hydrothermal and NaOH.The experimental equipment is used to evaluate desulfurization and denitrification performance and the samples are characterized by proximate and ultimate analysis,SEM,FT- IR and BET.The results show that the removing effect of AC modi…
Pure K2Ti4O9 whiskers were prepared by KDC(Kneading-Drying-Calcination) method with TiO2 and K2CO3 as raw materials. The influences of TiO2/K2CO3 molar ratio(RT/K), calcination temperature(TC) and cooling process on phase composition and morphology of the whiskers were investigated by TG-DSC(thermo gravimetric-differe…
The Al/Pb–0.8%Ag and Al/Pb–0.75%Ag–0.03%Co(in mass fraction) anodes used in zinc electrowinning are prepared through the electrodeposition of lead methanesulfonate electrolyte onto an aluminum matrix.The results of anode polarization curves,Tafel curves,and EIS characterizations indicated that the Al/Pb–0.75%Ag–0.03%C…
以便在微观结构和房间温度上调查 N 的效果新型的高硅 martensitic 的机械性质耐热的钢，包含 N 满足的 C 和 N 满意却不同的一样的总数的三钢根据 thermo 计算计算被设计了并且准备。热力学的计算和实验显示由 N 代替 C 改变类型和体积部分显著地高 Si martensitic 钢猛抛。与增加的 N 内容一起，在在 750 以后的样品的 precipitates？？
裂缝洞应力的精确决心具有中央重要性基于裂缝闭合模型使裂缝生长分析和生活预言疲劳。这份报纸为中心裂缝和边裂缝紧张标本学习裂缝洞行为。裂缝洞压力被裂缝尖端元素影响，这被发现。由考虑裂缝尖端元素，一个修改裂缝洞压力方程为中心裂缝紧张标本被给。为在在遥远的一致紧张和部分分布式的压力下面的一个半无限的盘子中的一个边裂缝的裂缝表面排水量方程被使用重量功能方法导出。把排水量基于这些，为在在一致紧张下面的一个半无限的盘子中的一个边裂缝的一个裂缝洞压力方程被开发了。学习证明裂缝开始压力是几何学依赖者，并且重量功能方法提供一个有效、可靠的工具处理如此的几何学依赖。
Shape-memory effect(SME) is the ability of a material to change its dimension in a predefined way in response to an external stimulus. Polymers that exhibit SME are an important class of materials in medicine, especially for minimally invasive deployment of devices. However, the rate of translation of the concept to a…
Further development of the photovoltaic industry is restricted by the productivity of mono-crystalline silicon technology due to its requirements of low cost and high efficient photocells.The heat shield is not only the important part of the thermal field in Czochralski(Cz)mono-crystalline silicon furnace,but also one…
TiC–TiB2 /Cu composites were prepared by self-propagating high-temperature synthesis with pseudo hot isostatic pressing using Ti, B4 C, and Cu powders. The compressive deformation of the composites at high temperature was investigated. It is found that the maximum compressive strength decreases with the increase of te…
Previous studies have shown that chrysophanol protects against learning and memory impairments in lead-exposed adult mice. In the present study, we investigated whether chrysophanol can alleviate learning and memory dysfunction and hippocampal neuronal injury in lead-exposed neonatal mice. At the end of lactation, chr…
A series of mesoporous phosphotungstic acid/alumina composites(HPW/Al2O3) with various HPW contents were synthesized by evaporation-induced self-assembly method. These composites were characterized by nitrogen adsorption-desorption, TEM, FTIR, and UV-vis, and were tested as catalysts in oxidation desulfurization of mo…
机能上地分级(FG ) 碳 nanotubes (CNT ) 和 nano 硅碳化物(nSiC ) 增强了铝(艾尔) 矩阵 composites 成功地用列在后面由的高精力的球 milling 被制作了固态火花血浆 sintering 过程。CNT 作为一个稳固的混合代理人在用 nSiC 的艾尔粒子是分散得好的。多围的 CNT 的二种不同类型被用来在一样的体积增加 CNT 的不同数量。球 milled Al–CNT–nSiC 和 Al–CNT 粉末混合物充分被使增加密度并且在 FG 以内没有严肃的 microcracks 和毛孔表明了好粘附多层合成。每层包含了 CNT 的不同数量，并且 nSiC 增加显示出不同微观结构和坚硬。控制…
水供应是一个城市的系统的主要元素。由于快速的都市化和水缺乏，坚持说一个马厩和安全的水供应成为了挑战到许多城市，而大量水从分发系统的管子被失去。水漏是水资源的浪费不仅，而且招致大社会经济的费用。这篇文章在潜在的水漏控制途径上介绍全面评论并且明确地讨论各个的好处到环境保存。水漏能被通过仪器的预兆的建模并且监视的联合改进漏察觉能力进一步减少，这被结束，优化管子维护策略，并且开发一个立刻的压力规定系统。因为水积蓄和精力消费的减小，环境能象温室气体排出物一样得益于这些行动。
