The number average degree of polymerization and polydispersity i…
The results of studying properties of the ceramic coatings: aluminum oxide, aluminum oxide with 13% of titanium, and magnesium aluminum spinel (obtained using the method for plasma spraying on the substrates made of the alloy Inconel 718 and the steel 316L(N)) are given. The tribological tests of the plasma coatings h…
Poly(dimethylsiloxane) (PDMS) based pentablock copolymers have been synthesized via atom transfer radical polymerization (ATRP) of methyl methacrylate (MMA) and vinyl acetate (VAc) telomer at 60°C in the presence of CuCl/PMDETA as the catalyst system. The vinyl acetate telomer was prepared from controlled radical telo…
研究了温度范围在723-908K的LiCl-KCl熔盐体系中MgCl2的电化学行为和热力学性质.循环伏安和方波伏安法研究表明镁离子的电化学还原过程为包含了两个电子转移的一步反应.利用Berzins和Delahay方程计算了不同温度下的镁离子的扩散系数,并通过Arrhenius公式计算了镁离子在LiCl-KCl熔盐体系中的扩散活化能.采用开路计时电位法得到了不同温度下的Mg(II)/Mg(0)体系的平衡电位,并结合电动势法计算了在LiCl-KCl熔盐体系中Mg(II)/Mg(0)体系的标准形式电位.根据不同温度下的标准形式电位,计算得到了MgCl2在LiCl-KCl熔盐体系中的熵变和焓变以及不同温度下的活度系数.
Driven by a good combination of strength and ductility, austenitic stainless steels have attracted much interest in the past decade. These metastable alloys fall into the category of transformation induced plasticity (TRIP) steels in which high strength and excellent ductility can be achieved due to their strain-induc…
In an effort to improve the operability of a weak nitric acid recovery unit operated by the Innovative Plastics division of Saudi Basic Industries Corporation (SABIC), a technology team from SABIC initiated a study to understand the root cause of the occasional loss of adequate control of the operating temperature and…
1,4-Bis(1-piperidineethyl)piperazine tetradentate N4 type of ligand synthesized from piperazine and 1-(2-chloroethyl)piperidine HCl. The Cu(II), Pd(II), Fe(III) and Mn(II) complexes of ligand N4 were synthesized by taking 1:1 ration of M:N4. The ligand and complexes have been characterized by elemental analyses, H-NMR…

采用固相反应法将五水硝酸铟(In(NO3)3·5H2O)、硝酸银(AgNO3)混合作为前驱体,在室温下研磨反应得到混合物颗粒,在600℃的温度下煅烧2h,可得银掺杂的In2O3的纳米颗粒,然后组装成气敏传感器。利用X-射线衍射仪(XRD)、扫描电子显微镜(SEM)、X-射线光电子能谱仪(XPS)、气敏测试系统(WS-30A)对薄膜进行表征及气敏性能测试。结果表明,制备的银掺杂In2O3的纳米颗粒直径约为80nm,银颗粒在煅烧过程中已经渗透进立方晶型的In2O3晶格中。相比较纯的In2O3传感器,银掺杂后的In2O3传感器对乙醇显示了更高的灵敏度、更高的选择性以及理想的工作温度。对银掺杂的含量、乙醇蒸汽的浓度以及工作温度对气敏性能的…
Effects of corrosion on military equipment and weapons is one of the key factors in the terms of safety, economy and ecology. Corrosion activity can be stopped or prevented by applying anti-corrosion coatings and coating formation, which primarily creates a barrier to the corrosive environment. Most of the anticorrosi…
Fibrous entangled media are interesting architectured materials because of their numerous different applications, such as thermal insulation, mechanical reinforcement, filtration and biomedicine. Entangled materials have recently been more investigated, due to the poor mechanic properties (such as frailness) that usua…
The work is devoted to theoretical investigations of the characteristics of a tetrahedral (square), hex and cylindrical (circular) honeycomb. Evidence of theoretical researches allows to determine the carrying capacity of sandwich beams (TB), square, hexagonal and a cylindrical paper honeycomb and compare beam with an…
Growth by interface motion takes place in many different systems ranging from mesoscopic scales (solidification) to geophysical scales (earth crust formation). Despite this diversity, it displays a number of similar features that refer to a common understanding. They include the segregation of compositions by fraction…
Catalytic partial oxidation (CPO) is considered to be a promising route to produce synthesis gas from methane. In this work cobalt supported on CeO2−Al2O3 nanocomposites calcined at temperatures ranging from 1173 K to 1473 K have been characterized and tested in a lab-scale reactor. The characterization techniques app…
