Polycarbonate Vitrimers and Dynamic Co‐Networks From Epoxide/Carbon Dioxide Copolymerization

Macromolecular Rapid Communications, EarlyView.
This work demonstrates how CO2‐derived poly(propylene carbonate) and poly(cyclohexene carbonate) backbones influence vitrimer thermo‐mechanical behavior. By tuning backbone composition, epoxide crosslinker chemistry and blend ratios, the crosslinked materials span a wide property window, from highly extensible to stiff, glassy networks, establishing an

Kinetics of ε‐Caprolactone Ring Opening Polymerization: Experimental and Modeling Study

Journal of Polymer Science, EarlyView.
We present a multi‐scale model for the ring‐opening polymerization of ε‐caprolactone to polycaprolactone (PCL), approximating final melt properties. We conducted batch experiments at various temperatures and reactant ratios. Using this data, we determined the kinetic parameters.

Investigating the Iron‐Steam Process for Coupling With SOEC and SOFC: A Step Toward Integrated Hydrogen and Electricity Storage

steel research international, EarlyView.
Fixed‐bed reactor experiments (10 L) validate the iron–steam redox process, bridging material‐scale research and industrial power‐to‐power applications. Coupled with SOEC/SOFC systems, this framework defines critical interfaces for heat and gas management. Results confirm reproducible hydrogen storage and release, demonstrating technical feasibility at

Effective Equilibrium Reaction Zone Modeling of Hydrogen Plasma Smelting Reduction: A Scenario Analysis

steel research international, EarlyView.
The study presents a dynamic zonal model for hydrogen plasma smelting reduction (HPSR) in direct current arc furnaces, predicting time‐dependent behavior of metal, slag, and off‐gas. The study considers various industrial scenarios to quantify energy demand, hydrogen utilization, degree of reduction, and other operational sensitivities.

Insights Into the Mechanistic Assessment of Plasmon‐Induced Aqueous Degradation of Pharmaceuticals by TiO2/Ag Nano‐Composite

Water and Environment Journal, EarlyView.
ABSTRACT Pharmaceutical contaminants in potable water sources are ubiquitous and have resulted in lowered water quality. Thus, two common broad‐spectrum pharmaceuticals (tetracycline‐TC and ciprofloxacin‐CPF) were comparatively photo‐degraded using Ag‐doped TiO2 photocatalyst species containing Ag nanoparticles at 2.5, 5, and 7.5 wt%.

Sustainability Assessment of Alternative Methods for Destruction of Per‐ and Polyfluoroalkyl Substances (PFAS) in Water

Remediation Journal, Volume 36, Issue 2, Spring 2026.
ABSTRACT Per‐ and polyfluoroalkyl substances (PFAS) are persistent environmental contaminants widely recognized for their resistance to degradation and potential adverse health effects. The treatment of PFAS‐contaminated aqueous media (e.g., drinking water, wastewater, and leachate) has been extensively studied in the published literature; however, the
