镀锌层上有机物无铬钝化涂层的耐蚀性

选择了一种无毒的水溶性丙烯酸树脂（AC）加入至钼酸盐、磷酸盐中（M）得到一种钝化液（ACM），对镀锌层进行钝化处理以代替有毒的铬酸盐钝化。通过盐雾试验、扫描电镜、电化学测试等手段，研究了该纯化膜的耐蚀性及耐蚀机理。结果表明，热浸镀锌层采用该无毒钝化液进行钝化，可以推迟镀锌层出现白锈的时间，其抗蚀性已接近铬酸盐钝化水平；ACM钝化膜耐蚀性的提高是由于钝化膜中的钼酸盐与丙烯酸树脂产生交联作用，抑制钝化膜裂纹的扩展，同时由于膜层中钼酸盐的缓蚀作用，提高了镀锌层的抗蚀性。

Activation of hydrogen storage materials in the Li–Mg–N–H system: Effect on storage properties

We investigate the thermodynamics, kinetics, and capacity of the hydrogen storage reaction: Li₂Mg(NH)₂ + 2H₂  Mg(NH₂)₂ + 2LiH. Starting with LiNH₂ and MgH₂, two distinct procedures have been previously proposed for activating samples to induce the reversible storage reaction. We clarify here the impact of these two activation procedures on the resulting capacity for the Li–Mg–N–H reaction. Additionally, we measure the temperature-dependent kinetic absorption data for this hydrogen storage system. Finally, our experiments confirm the previously reported formation enthalpy (ΔH), hydrogen capacity, and pressure–composition–isotherm (PCI) data, and suggest that this system represents a kinetically (but not thermodynamically) limited system for vehicular on-board storage applications.

Nafcillin release from poly(acrylic acid–co–methyl methacrylate) hydrogels

Summary Copolymeric poly(acrylic acid-co-methyl methacrylate) hydrogels for three different compositions: (90/10), (80/20) and (60/40), have been studied. Drug release has been examined as a function of the hydrogel composition by HPLC (High Pressure Liquid Cromatography). The release experiments were carried out at 37 °C. The fraction of available drug release was linear in t^1/2. The values of the diffusional coefficient (0.50<n<1.0) indicate that the nafcillin release mechanism from the hydrogels in study is non-Fickian. The diffusion coefficients for this drug release have been calculated. The molecular diffusion of nafcillin through hydrogels is controlled by the swelling.
