Enhancement of Chemical Stability of Sulfonated Polyvinylidene Fluoride Proton‐Conducting Membranes by Ceria Incorporation

Journal of Polymer Science, EarlyView.
The chemical stability of SPVDF membranes was examined using Fenton's reagent test. It was found that the chemical stability of membranes was enhanced from around 80% to 96% by integration of ceria in the membranes. The ability of ceria to toggle between the two oxidation states was responsible for this enhancement.

Gas–liquid mass transfer enhancement in the presence of nanoparticles under slug flow in microreactors

AIChE Journal, Volume 72, Issue 10, October 2026.
Abstract Nanofluids containing nanoparticles represent a promising solvent or reaction system for gas–liquid operations. Herein, the effect of nanoparticle (Al2O3 and SiO2) addition on gas–liquid slug flow pattern and mass transfer enhancement was investigated during CO2 absorption into water in microreactors.

A Review on Polymer Bonding Through Interdiffusion and Role of Deformation‐Acceleration

Macromolecular Materials and Engineering, Volume 311, Issue 9, September 2026.
Polymer bonding is reframed through deformation‐induced bonding, an energy‐efficient route that joins polymer films without conventional heat‐intensive or adhesive‐based processing. By comparing established bonding methods with deformation‐induced bonding, this review highlights potential energy and cost savings while identifying opportunities across ...
