植物生物技术在开发食品资源中的应用

粮食、豆类、油料、蔬菜、干鲜果等植物产品是人类食物的重要组成部分,是食品加工的重要原料.近年来,人们应用植物生物技术开发植物性食品.例如,运用茎尖培养除病毒,保持果实的风味;通过筛选突变体提高营养价值;操纵遗传密码,改进加工品质.植物次生物质是天然产物的重要来源,开发天然食品添加剂就是要合理利用植物次生物质.人们开始运用植物组织细胞培养乃至运用类似于微生物发酵的手段,通过植物细胞成批培养,固定化植物细胞和生物转化,生产出天然的调味剂、芳香剂、色素等.植物生物技术用于开发食品资源有着广阔的前景.

添加剂强化沸腾传热性能的综合评价及预测

用模糊数学的方法对添加剂强化沸腾传热的性能建立了评价及预测模型。对文献中及作者试验过的３７种添加剂强化沸腾传热的效果作了拟合评价，结果表明，有３３种添加剂的评价结果与实测结果相符合，准确率为８９．２％．此外，还对油酸钠和聚乙烯醇两种添加剂强化沸腾传热的能力作了预测，结果也与实测结果相吻合．     

油溶性有机钼添加剂的研究——二仲辛基二硫代磷酸钼性能的评定

本文研究了不同浓度的二仲辛基二硫代磷酸钼加入150~#中性油和10~#汽油机油中的基本性能。对其进行了抗摩、减磨及抗氧化试验。试验表明,油溶性二仲辛基二硫代磷酸钼作为滑润油添加剂,能够有效地降低滑动表面的摩擦和磨损,提高承载能力。特别是低浓度二仲辛基二硫代磷酸钼,直接加入全配方的10~# 汽油机油中,可以得到更好的减摩效果。     

BaCO3和SrCO3对水泥生料固硫行为的影响

针对水泥窑工艺,以合山东矿煤和贵州六盘水煤为研究对象,水泥生料为固硫剂,BaCO3和SrCO3为添加剂,进行燃烧固硫的试验研究,在讨论添加剂对水泥生料固硫效率影响的同时,借助XRD测试手段研究BaCO3和SrCO3对灰渣产物矿相组成的影响规律,并结合灰渣扫描电镜分析,探讨高温段添加剂对水泥生料的固硫效果的作用机理.结果表明水泥生料中添加BaCO3和SrCO3后,在较低温度下促使SOx的析出量增加,水泥生料固硫效率降低.但是随着温度的升高,添加剂的加入,促使灰渣结构更为密实,从而更好地抑制CaSO4的高温分解,固硫效果改善.其中钙与添加剂的质量比为7时效果最好,但对于不同煤来说,最佳添加剂比例不同.     

Influences of Electrolytes on Soap-Free P（ST-MMA-AA） Emulsion Polymerization

1 Introduction Functional polymer microspheres are kinds of polymer particles with special structures, morphologies or functional groups~([1]), and have been gained much attention because of their specific properties and their application since 1980s. Although some researches have investigated that the latex particle size and its distribution, as well as the stability of polymerization and the resultant latex were strongly influenced by introducing electrolyte into the emulsion polymerization …     

Tin Oxide and Carbon Composite （Sn6O4（OH）4/AG） as the Anode in a Lithium Ion Battery

A tin oxide and carbon composite （Sn6O4（OH）4/AG） with a Sn content of 0.15-0.30 was prepared by chemical deposition at normal pressures and temperatures. The structures of the artificial graphite （AG）, the Sn6O4（OH）4, and the Sn6O4（OH）4JAG were analyzed using X-ray diffraction. The electrochemical lithiation was investigated by measuring the galvanostatic charge and discharge ratio. The electrochemical capacities of the three materials during the first discharge were 310 mAh/g （AG）, 616 mAh/g （Sn6O4（OH）4/AG）, and 1090 mAh/g （Sn6O4（oa）4）. The discharge capacity of the Sn6O4（OH）4/AG was larger than the simple sum of the capacities provided by AG and Sn6O4（OH）4 with the same content. The cyclic performance of Sn6O4（OH）4/AG was also better than that of Sn6O4（OH）4 for voltages of 0 to 3 V. The results imply that the interaction between Sn and C in Sn6O4（OH）4/AG is very strong and effectively inhibits the volume expansion of the Sn.

Microporous polymer electrolyte based on PVDF-PEO

Since Wright et al. found that the complex of PEO/alkali metals salt had the ability of ionic conductivity in 1973, in-depth studies have been carried out about various polymer electrolytes, which were applied to replacing the liquid electrolytes in lithium ion battery. At present, polymer electrolytes mainly include three kinds:
