NSF-CGP Science Fellowship Program: Studies of Metal Boride Surfaces

9404687 Trenary该奖项资助伊利诺伊大学芝加哥分校化学系Michael Trenary博士在日本与东京早稻田大学应用物理系教授Chuhei Oshima进行一年的金属硼化物表面合作研究的海外旅费。金属硼化物是一种耐人寻味的材料；极硬，化学惰性，具有非常高的熔点。许多材料还具有独特的表面性质，这使得它们在各种应用中都很有用，例如用作各种电子光学设备中的电子发射阴极。大岛博士是稀土六硼化物表面科学领域公认的领导者。特伦纳里博士和他的学生最近对六硼化镧表面的原子结构进行了扫描隧道显微镜研究，并对氧化表面的氧化物蒸发进行了质谱学研究。将在早稻田大学进行的实验包括一氧化碳、水和氢在六硼化镧表面的吸附和解离，以及含硼和碳原子的类石墨单分子膜在金属二硼化物表面的生长和表征。将使用的主要技术是高分辨率电子能量损失谱。这项研究工作应该会在东京和芝加哥的两个研究小组之间产生长期的合作互动。该奖项是由日本基金会全球伙伴关系中心(CGP)根据NSF-CGP科学奖学金计划资助的。***

9404687 Trenary This award supports the foreign travel expenses for Dr. Michael Trenary, Chemistry Department at the University of Illinois at Chicago, to spend a year in Japan conducting collaborative research studies on metal boride surfaces with Professor Chuhei Oshima of the Department of Applied Physics at Waseda University in Tokyo. Metal borides are intriguing materials; extremely hard, chemically inert and possessing very high melting points. Many also have unique surface properties making them useful in various applications such as use as an electron emitting cathode in a variety of electron optical devices. Dr. Oshima is a recognized leader in the surface science of rare-earth hexaborides. Dr Trenary and his students have recently conducted a scanning tunneling microscopy study of the atomic structure of a lanthanum hexaboride surface and a mass spectrometric study of oxide evaporation from the oxidized surface. The experiments to be conducted at Waseda University consist of studies of adsorption and dissociation of carbon monoxide, water and hydrogen on the lanthanum hexaboride surface, and the growth and characterization on metal diboride surfaces of graphite-like monolayers containing boron and carbon atoms. The principle technique to be used will be high resolution electron energy loss spectroscopy. This research work should result in a long term collaborative interaction between the two research groups in Tokyo and Chicago. This award is funded under the auspices of the Center for Global Partnership (CGP) of the Japan Foundation under the NSF-CGP Science Fellowship Program. ***
