SGER: Gas phase nucleation of diamond: synthesis of nano-diamond powders

翻译后摘要：本建议的主要目的是确定是否由PI开发的新型微等离子体反应器可以提供一种方法，纳米级金刚石晶体的均匀气相成核。 将尝试三种类型的分子筛：笼状烃分子金刚烷，烃生成的石墨烟灰，和硅烷生成的硅。 这三条路线都有成功的假设原因，但需要进行测试以探索科学和技术的可行性。 此外，PI的大气压微等离子体已显示出希望，但尚未为此目的进行测试。 拟议工作的预期更广泛的影响是创造一种新形式的钻石，可以印在表面上或更容易衍生，提供电子，传感器和生物医学应用。

Abstract:The main objective of this proposal is to determine whether novel microplasma reactors developed by the PI can provide a method for homogeneous gas-phase nucleation of nanoscale diamond crystals. Three types of molecular seedings will be attempted: the cagelike hydrocarbon molecule adamantane, hydrocarbon-generated graphitic soot, and silane-generated silicon. All three routes have hypothetical reasons for success, but testing will be required to explore the science and technological feasibility. Furthermore, the PI's atmospheric-pressure microplasmas have shown promise but have not been tested for these purposes. The intended broader impact of the proposed work is creating a new form of diamond that could be imprinted onto surfaces or more easily derivatized, offering electronic, sensor, and biomedical applications.
