STTR Phase II: A Simple and Innovative Approach to the Synthesis of Metal, Alloy, Metal Oxide, and Mixed-Metal Oxide Nanoparticles

这个小型企业技术转移(STTR)第二阶段项目旨在开发一种合成金属氧化物、硫化物和其他纳米颗粒的制造工艺。主体法只是简单地混合普通的干化学原料，并将得到的前体材料加热到适度的温度。其目的是证明这种低成本制造工艺的可行性和可扩展性。还将研究在水和极性溶剂中分散聚集粒子的方法。该项目的更广泛的商业影响将是提供一种具有成本效益和环境友好的工艺来生产广泛的高质量纳米颗粒。目前制造纳米粒子的方法涉及大量能源消耗、大量废物和/或净化问题。该项目中的合成方法有可能成为在许多低技术到高技术应用中提供新型纳米颗粒的选择方法。预计将获得粒径小于15 nm、尺寸变化在±10-20%内、纯度高达99.9999%的纳米颗粒。

This Small Business Technology Transfer (STTR) Phase II project aims to develop a manufacturing process to synthesize metal oxide, sulfide and other nanoparticles. The subject method simply involves mixing of common dry chemical starting materials and heating the resulting precursor material to a modest temperature. The objective is to demonstrate feasibility and scalability of this low-cost manufacturing process. Methods of dispersing aggregated particles in aqueous and polar solvents will be also be investigated.The broader/commercial impact of this project will be the potential to offer a cost-effective and environmentally-friendly process to produce a broad spectrum of high quality nanoparticles. Current methods of making nanoparticles involve heavy energy consumption, large amounts of waste, and/or purification problems. The synthetic approach in this project has the potential to become the method of choice to supply novel nanoparticles in many low to high technology applications. It is anticipated to obtain nanoparticles with particle sizes less than 15 nm, size variations within ±10-20%, and purities as high as 99.9999%.
