Synthesis of Pt Carbon Aerogel Electrocatalysts with Multiscale Porosity Derived from Cellulose and Chitosan Biopolymer Aerogels via Supercritical Deposition for Hydrogen Evolution Reaction

Advanced Energy and Sustainability Research, EarlyView.
The synthesis of platinumcarbon aerogel electrocatalysts with multiscale porosity derived from biopolymer aerogels via supercritical deposition is presented. The electrocatalysts demonstrate similar overpotentials to commercial alternatives with significantly higher platinum loadings, while exhibiting superior stability due to enhanced porosity ...

Comments on Van der Waals supercritical fluid: Exact formulas for special lines [J. Chem. Phys. 135, 084503 (2011)] [PDF]

arXiv, 2018
The equations for Widom lines for the supercritical van der Waals fluid were considered in the paper J. Chem. Phys. 135, 084503 (2011). But the equations for the speed of sound and its special Widom line were incorrect. The correct equations are obtained.

A semi‐implicit finite volume scheme for a simplified hydrostatic model for fluid‐structure interaction

International Journal for Numerical Methods in Fluids, Volume 95, Issue 1, Page 107-142, January 2023., 2023
In this article, a novel mass and momentum conservative semi‐implicit finite volume scheme is developed for the coupled solution of hydrostatic shallow water flow and the movement of one or more floating rigid bodies. The coupling is achieved via a nonlinear volume function in the mass conservation equation that depends on the coordinates of the ...

Characterization of ultrasonically extracted flaxseed polysaccharide gum and assessing its lipid‐lowering potential in a rat model

Food Science &Nutrition, Volume 11, Issue 1, Page 137-147, January 2023., 2023
On the basis of current research it was suggested that FPG have anti‐hyperlipidemic potential. Still, the mechanism of actions of FPG as anti‐hyperlipidemic and other therapeutic potential have yet to be explored. Abstract Flaxseed polysaccharide gum (FPG) was extracted through the ultrasound‐assisted process using water as a solvent with a yield ...

Preparation of Carbon Fiber–Reinforced Polymer Using Oxidatively Degradable Matrix Polymer: Recovery and Reuse of Carbon Fiber Sheet

Journal of Applied Polymer Science, EarlyView.
Carbon fiber–reinforced polymer (CFRP) was prepared from carbon fiber (CF) sheet with a diacylhydrazine‐crosslinked matrix polymer. The CF sheet was recovered without damage when the CFRP plate was treated with sodium hypochlorite NaClO solution.
