Concave microlens arrays with tunable curvature for enhanced photodegradation of organic pollutants in water: A non-contact approach
Download2023-11-01
Lu, Qiuyun, Li, Yanan, Kassim, Kehinde, Xu, Ben Bin, El-Din, Mohamed Gamal, Zhang, Xuehua
Solar-driven photodegradation for water treatment faces challenges such as low energy conversion rates, high maintenance costs, and over-sensitivity to the environment. In this study, we develop reusable concave microlens arrays (MLAs) for more efficient solar photodegradation by optimizing light...

Quantifying the effects of dissolved nitrogen and carbon dioxide on drying pressure of hydrophobic nanopores
Download2023-05-26
Binyaminov, Hikmat, Elliott, Janet A. W.
The effects of a dissolved gas on the behavior of liquid in cylindrical nanopores are investigated in the framework of Gibbsian composite system thermodynamics and classical nucleation theory. An equation is derived relating the phase equilibrium of a mixture of a subcritical solvent and a...
