查询词典 lactic amide

The blends of PE-g-MAH and gelatin were prepared by melting process and the compatibility of PE-g-MAH and gelatin in blends were characterized. The results of FTIR showed that the characteristic absorption band peaks of amine and amide groups of gelatin were shifted in PE-g-MAH/Gelatin blends, the equilibrium values of torque were higher with the increase of blending temperature, which proved that graft copolymer PE-g-MAH-g-gelatin was formed during the preparation process, and the amount of PE-g-MAH-g-gelatin was increased with increasing the amount of PE-g-MAH. SEM micrographs exhibited that there was PE-g-MAH-g-gelatin formed in surface of gelatin phase.

通过红外光谱分析、HAAKE流变分析、抽提等实验证明：共混物中明胶的氨基、酰胺基团吸收峰峰位发生了明显的变化；在熔融共混过程中，随着温度的提高，平衡扭矩增大；明胶与PE-g-MAH发生了反应形成PE-g-MAH-g-明胶接枝共聚物，而且随着PE-g-MAH用量的增加，形成接枝共聚物的量也提高；SEM的实验结果表明，在明胶的表面确有接枝物形成；通过DMA测试共混物的玻璃化转变温度，发现两组分的玻璃化转变温度差值减小，二者的相容性提高，实现了共混体系的自增容。

In this research, mixed SAM of HS-(CH2)15-CH3 and HS-(CH2)15-COOH was immobilized on gold substrate through chemical bond, and PEG and PMB were in sequence linked to the –COOH terminal groups on the SAM sureface by EDC/NHS amide coupling. The PMB immobilized surface was applied to study its specific and nonspecific interactions with LPS by ellipsometry and by SPR spectroscopy. The modified surface is characterized by FTIR, XPS, ellipsometry and contact angle measurements.

This research utilized the method of organic synthesis, researching different amounts and positions of hydroxy-substituted benzoic acid and serotonin into amide reaction, so as to produce a series of polyhydroxy substituted N-benzoylserotonin derivatives (compound 1-10). Accordingly, this study conducts the following four tests. I. The activity of antioxidant and the experiment of ability to scavenge DPPH free radical, II. The ability of overall antioxidant—the activity of TEAC, III. The activity test of inhibit Tyrosinase, and IV. The study of absorbing UV / VIS Spectrophotometers. This study use trolox, arbutin, and octyl salicylate as the control groups, and to test the ability of anti-oxidation, the activity of inhibit Tyrosinase, and the ability of absorbing UV. This research ultimately intends to investigate the applied value of those compounds into cosmetics.
