华裔科学家对陶氏化学公司成长所作的贡献
关键字:华裔科学家 改善人民生活 近年来,多个跨国公司 包括陶氏化学先后宣布在中国成立研发中心,国内科研人员对跨国公司的企业文化,薪资报酬,以及 生涯规划等议题的讨论不绝于耳。但我门要问,当下中国科学家应该追求是什么?它的最高奖励又为何?最近的五位诺贝尔奖得主在访华临别记者招待会上给了中国科学家的一个建议 :现阶段中国不需要诺贝尔奖,中国需要能为改善人民生活和增进人民身体健康的科学家。非常有趣的是,这个建议和陶氏化学公...

美国麦克公司仪器在CO2温室气体贮存中的应用
关键字:压汞仪 能源 二氧化碳 许多与能源相关的二氧化碳管理办法,包括低碳能源(例如核能,太阳能,风能,地热能,和生物质能)。科学家们也开始寻求提高能源转换效率的方法,这样使用较少的矿物燃料就可满足相同能量输出需要。然而,尽管有希望,目前这些选择对矿物燃料的需求和使用影响相对较小。矿物燃料继续提供世界大部分能源消耗。日益增长的能源需求,选择替代能源的落后,全球经济仍然依赖矿物燃料且其相对较低的成本和高获得性,意味着矿物燃料的使用将...

Investigation on properties of P((MAA-co-DMAEMA)-
P((MAA-co-DMAEMA)-g-EG) polyampholyte nanogels (PANGs) were prepared by distillationdispersion copolymerization of poly(ethylene glycol) methyl ether methacrylate (MPEGMA), N,N-dimethylaminoethyl methacrylate (DMAEMA), and methacrylic acid (MAA) using acetonitrile (AN) as dispersion medium. The results of FTIR spectra indicate that the composition of P((MAA-co-DMAEMA)-g-EG) PANGs is consistent wit...

Self-polymerization and Co-polymerization Kinetics of Gadolinium Methacrylate
Gadolinium methacrylate (Gd(MAA)3) was synthesized by using gadolinium oxide and methacrylic acid as the starting materials and its self-polymerization kinetic was studied based on non-isothermal and isothermal analysis. Moreover, the monomer reactivity ratios of methyl methacrylate (MMA) and Gd(MAA)3 were evaluated by using Kelen-Tüd?s method. The thermal neutron shielding properties of PMMA a...

Statistically Syndioselective Coordination (Co)polymerization of 4-Methylthiostyrene
The homopolymerization of a polar monomer, 4-methylthiostyrene (MTS), was successfully achieved by a rare-earth metal based catalyst in the highest activity of 45.1 × 104 g molY–1 h–1and the excellent syndioselectivity (rrrr > 99%). The polymerization was rather controllable that the resultant poly(methylthiostyrene)s (PMTS) had molecular weights comparable to the theor...
