NER: Large-Scale Synthesis of Boron-containing Nanostructures

本研究的目的是制造氮化硼（BN）和硼碳氮化物（BCN）纳米结构在大规模的高产率和高单分散性的大小（直径），组成，并使用一组简单的实验协议。我们的目标是通过使用传统的无机化学原理来合理地开发适当的合成策略来产生大规模数量的BN和BCN纳米结构。该方法是开发（a）新的基板空间限制的反应过程，并诱导单分散性;（B）新的，可调的催化剂;和（c）易于加工的富含硼的有机金属和聚合物衍生的前体。采用两段炉系统的化学气相沉积技术将用于制造过程，因为这些技术适用于快速和高通量筛选拟议的催化剂，基底和前体。由于BN和BCN纳米结构对于高强度轻质材料，场发射器，光致发光器件，热稳定润滑剂，以及微波和红外透明材料。此外，这些材料具有工业上有用的气体储存和催化能力。产生的研究成果将被导入现有的研究生水平的表面科学课程，该课程已经突出了能源部布鲁克海文国家实验室科学家的前沿研究。最重要的是，这个项目将激发创建一个跨学科的联合斯托尼布鲁克- BNL纳米科学周日，向公众开放，这将不仅涉及领先的纳米研究人员，而且研究生，本科生，社区学院和高中参与者从当地社区。

The objective of this research is to manufacture boron nitride (BN) and boron carbon nitride (BCN) nanostructures on a large scale in high yield and with high monodispersity in size (diameter), composition, and alignment using a simple set of experimental protocols. The goal is to generate large-scale quantities of BN and BCN nanostructures by using traditional inorganic chemistry principles to rationally develop appropriate synthetic strategies. The approach is to develop (a) novel substrates to spatially constrain the reaction process and to induce monodispersity; (b) novel, tunable catalysts; and (c) readily processable boron-rich organometallic and polymer-derived precursors. Chemical vapor deposition techniques using a two-stage furnace system will employed for the manufacturing processes as these are appropriate for the rapid and high-throughput screening of the proposed catalysts, substrates and precursors.The research is of high societal benefit because of the importance of BN and BCN nanostructures for the practical development of high-strength lightweight materials, field emitters, photoluminescent devices, thermally stable lubricants, and microwave and infrared-transparent materials. Moreover, these materials possess industrially useful gas storage and catalytic capabilities. Generated research results will be channeled into an existing graduate-level surface science course, that already highlights cutting edge research from the Department of Energy's Brookhaven National Laboratory scientists. Most importantly, this project will inspire the creation of an interdisciplinary joint Stony Brook - BNL Nanoscience Sunday, open to the general public, which will involve not only leading nanoscale researchers but also graduate, undergraduate, community college, and high-school participants from the local community.
