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.

摘要：本提案的主要目的是确定 PI 开发的新型微等离子体反应器是否可以提供纳米级金刚石晶体均匀气相成核的方法。 将尝试三种类型的分子晶种：笼状碳氢化合物分子金刚烷、碳氢化合物生成的石墨烟灰和硅烷生成的硅。 这三种路线都有假设的成功原因，但需要进行测试来探索科学和技术的可行性。 此外，PI 的常压微等离子体已显示出前景，但尚未针对这些目的进行测试。 拟议工作的预期更广泛影响是创造一种新形式的金刚石，可以压印到表面或更容易衍生化，提供电子、传感器和生物医学应用。
