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...

Thermophysical properties and containerless 2 solidification of Al-22.5wt%Cu in reduced gravity using the ISS-EML
Download2023-01-01
Champdoizeau, Q., Valloton, J., Henein, H.
A hypoeutectic Al–22.5 wt pctCu sample was processed using the Electro-Magnetic Levitator on board of the International Space Station within the frame of the European Space Agency projects NEQUISOL and THERMOLAB. In total, 21 cycles of melting and cooling were carried out, with the last cycle...

Investigation of the Accelerated Thermal Aging Behavior of Polyetherimide and Lifetime Prediction at Elevated Temperature
Download2023-01-01
Cho C., Nam S.L., de la Mata P.A., Harynuk J.J., Elias A., Chung H-J, Dolez P.I.
Fire-protective clothing are manufactured using heat and flame resistant fibers that are made of high-performance polymers. These polymers exhibit a gradual reduction in their performance after long-term exposure under various aging conditions. This study investigates the thermal aging behavior...

Binyaminov, Hikmat, Elliott, Janet A. W.
This paper presents an exploration of a specific type of a generalized multicomponent solution model, which appears to be first given by Saulov in the current explicit form. The assumptions of the underlying theory and a brief derivation of the main equation have been provided preliminarily for...

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...

Billet, Romain, Zeng, Binglin, Wu, Hongyan, Lockhart, James, Gattrel, Mike, Zhao, Hongying, Zhang, Xuehua
Switchable hydrophilicity solvents (SHSs) are a unique class of chemical compounds that can be switched between their hydrophobic and hydrophilic forms. The switchable characteristics allow SHSs to be used as emerging, green solvents for sustainable extraction and separation technology. In the...

Sustainable ultra-strong thermally conductive wood-based antibacterial structural materials with anti-corrosion and ultraviolet shielding
Download2023-09-01
Ye, Haoran, Shi, Yang, Xu, Ben Bin, Guo, Zhanhu, Fan, Wei, Zhang, Zhongfeng, Mulvihill, Daniel M., Zhang, Xuehua, Shi, Pengju, He, Ximin, Ge, Shengbo
In light of the uprising global development on sustainability, an innovative and environmental friendly wood-based material derived from natural pinewood has been developed as a high-performance alternative to petrochemical-based materials. The wood-based functional material, named as BC-CaCl2,...

Effects of Gas Type, Oil, Salts and Detergent on Formation and Stability of Air and Carbon Dioxide Bubbles Produced by Using a Nanobubble Generator
Download2023-04-01
Zhou, Kaiyu, Maugard, Vincent, Zhang, Wenming, Zhou, Joe, Zhang, Xuehua
Recent developments in ultrafine bubble generation have opened up new possibilities for applications in various fields. Herein, we investigated how substances in water affect the size distribution and stability of microbubbles generated by a common nanobubble generator. By combining light...
