标题:在 193 Nm 光子照射下,在 295 K 下吸附的碲和烷基镉物质的光解
摘要:已经使用 X 射线光电子能谱研究了在超高真空条件下在 295 K 下吸附碲和烷基镉形成的物质的光解分解.已观测到吸附在多晶金基材上的亚单层覆盖的二甲基碲在 193 Nm 处经历几乎定量的光解分解,形成金属碲.分解中产生的碳氢化合物光碎片导致金表面上的碳污染可忽略不计.吸附在无定形 Sio2 上的二甲基镉既解吸又分解形成金属副产物.在这种情况下,大部分碳仍为碳氢化合物和碳化物污染物.在 Si(100) 和 Gaas(100) 表面上形成的两种金属的单甲基化合物在低通量 (0. 25 Mj Cm−2) 用于这些实验;然而,观测到大量解吸.

标题:Greener Synthesis of Nanoparticles Using Fine Tuned Hydrothermal Routes
发明人：MAYE MATHEW
权利人:MAYE MATHEW; UNIV SYRACUSE
摘要:The synthesis of energy and sensor relevant nanomaterials that involves the colloidal synthesis of quantum dots (e.g. CdSe, CdS, ZnS, CdSe/ZnS) under well-controlled hydrothermal conditions (100-200 degrees C.) using simple inorganic precursors. The resulting nanomaterials are of high quality, and are easily processed depending upon application, and their synthesis is scalable. Scalability is provided by the use of a synthetic microwave reactor, which employs dielectric heating for the rapid and controllable heating.
