This project aims to study the nano-structured silica formation under microgravity conditions using a sol-gel process. In the absence of gravitional forces and associated free convective disturbances, the sol reaction in our preliminary testing with NASA has revealed fundamental reorganisation in nano properties (i.e. fractal dimension, pore size, surface area and pore volume) as compared to tests carried out under normal gravity conditions. This is a key feature of scientific interest for the production of nanomaterials for applications such as linear and non-linear optical materials and quantum materials.

本项目旨在研究微重力条件下使用溶胶-凝胶工艺形成纳米结构二氧化硅。 在重力和相关的自由对流扰动的情况下，溶胶反应在我们的初步测试与美国宇航局揭示了基本重组纳米性能（即分形维数，孔径，表面积和孔体积）相比，在正常重力条件下进行的测试。 这是生产用于线性和非线性光学材料和量子材料等应用的纳米材料的科学兴趣的一个关键特征。
