摘要:通过 X 射线衍射和差示扫描量热法(dsc)研究了熔淬无定形 Al85Ce5Ni8Co2 合金的热稳定性和结晶动力学.玻璃化转变之后是过冷液态区(21 oc),然后是两步结晶过程.最终的微观结构包含 Al3Ce,α-Al,Al3Ni 和 Al9Co2 相.在 275-285 oc 范围内对淬火样品进行的等温退火表明,两个结晶反应都是通过成核和生长过程发生的.为了研究材料的结晶动力学和稳定性,还在预退火后进行了不同时间的连续加热 Dsc 测量.对等温 Dsc 曲线进行的 Avrami 分析表明,随着退火温度的升高,三维成核和生长过程变得更加主要.平均比晶界能量与高角度晶界相对应,表明存在独立的成核事件.

标题:Chemical amplification for the synthesis of patterned arrays

摘要:Radiation-activated catalysts (RACs), autocatalytic reactions, and protective groups are employed to achieve a highly sensitive, high resolution, radiation directed combinatorial synthesis of pattern arrays of diverse polymers. When irradiated, RACs produce catalysts that can react with enhancers, such as those involved in autocatalytic reactions. The autocatalytic reactions produce at least one product that removes protecting groups from synthesis intermediates. This invention has a wide variety of applications and is particularly useful for the solid phase combinatorial synthesis of polymers.

摘要:Methods and intermediates for the synthesis of selective inhibitors of dipeptidyl peptidase IV (DPP-IV) are provided. Coupling of a carboxylate salt with a boro-proline derivative provides a protected form of a DPP-IV inhibitor, which may be deblocked to yield the medicinal compound. The carboxylate salt can be a crystalline form of a sodium salt or a dicyclohexylammonium salt. The inhibitor can be used in the treatment of diabetes.
