摘要

本文采用重量法和气体散射介质吸收光谱（GASMAS）两种不同的方法，研究了尺寸分布明显、平均孔径为50、80和150 nm的商用氧化铝圆盘中的水逸出和侵入动力学。在环境空气中进行测量之前，样品最初被放置在水饱和的环境中进行逃逸研究，而在入侵研究中，它们最初被放置在真空环境中。两种方法的结果一致，表明逃逸和侵入过程的时间常数与平均孔径成反比。然而，GASMAS方法具有区分样品中的水蒸气和液体含量并同时评估它们的能力。

Study of water escape and invasion in nanoporous alumina using GASMAS and gravimetric methods

This study investigates water escape and invasion dynamics in commercial alumina discs, which have sharp size distributions and average pore sizes of 50, 80, and 150 nm, using two different methods, namely, gravimetric and Gas in Scattering Media Absorption Spectroscopy (GASMAS). Before performing measurements in ambient air, the samples were initially placed in a water-saturated environment for the escape study, while for the invasion study, they were initially put in a vacuum environment. Both methods were found to agree and revealed that the time constants for escape and invasion processes were inversely proportional to the average pore sizes. However, the GASMAS method has the capability of distinguishing between water vapor and liquid content in the samples and assessing them simultaneously.

期刊介绍： Results in Physics is an open access journal offering authors the opportunity to publish in all fundamental and interdisciplinary areas of physics, materials science, and applied physics. Papers of a theoretical, computational, and experimental nature are all welcome. Results in Physics accepts papers that are scientifically sound, technically correct and provide valuable new knowledge to the physics community. Topics such as three-dimensional flow and magnetohydrodynamics are not within the scope of Results in Physics. Results in Physics welcomes three types of papers: 1. Full research papers 2. Microarticles: very short papers, no longer than two pages. They may consist of a single, but well-described piece of information, such as: - Data and/or a plot plus a description - Description of a new method or instrumentation - Negative results - Concept or design study 3. Letters to the Editor: Letters discussing a recent article published in Results in Physics are welcome. These are objective, constructive, or educational critiques of papers published in Results in Physics. Accepted letters will be sent to the author of the original paper for a response. Each letter and response is published together. Letters should be received within 8 weeks of the article''s publication. They should not exceed 750 words of text and 10 references.
