WAXS监测氖在介孔二氧化硅玻璃中的单层吸附
Monolayer sorption of neon in mesoporous silica glass as monitored by WAXS
摘要:
我们报告的X射线散射强度的测量中孔玻璃充满氖。我们概述了一个简单的模型,以占的非线性增加的第一个峰的强度在一个液体样的衍射图案作为一个单层形成。这使我们能够展示一种不依赖于热力学模型的表面积测定方法,因此与现有模型是互补的。
英文摘要:
We report measurements of the x-ray scattering intensity as mesoporous glasses are filled with Neon. We outline a simple model to account for the non-linear increase in the intensity of the first peak in a liquid-like diffraction pattern as a monolayer is formed. This allows us to demonstrate an approach for surface area determination which does not rely on thermodynamic models, and is therefore complimentary to existing models.
