Chemical kinetic analysis of hydrogen-air ignition and reaction times [PDF]

open access: yes
An anaytical study of hydrogen air kinetics was performed. Calculations were made over a range of pressure from 0.2 to 4.0 atm, temperatures from 850 to 2000 K, and mixture equivalence ratios from 0.2 to 2.0.

Plastics of the Future? An Interdisciplinary Review on Biobased and Biodegradable Polymers: Progress in Chemistry, Societal Views, and Environmental Implications

open access: yesAngewandte Chemie International Edition, EarlyView.
This interdisciplinary article explores the potential of biodegradable and biobased polymers (BBPs) to address plastic pollution and microplastic generation. It examines feedstock selection, chemical modification, use, and end‐of‐life scenarios, including biodegradation and environmental impact of BBPs.

Impact of Aluminum Diethyl Phosphinate (DEPAL) Flame Retardant on the Thermal, Mechanical, and Fire‐Resistance Properties of an Amine‐Cured Epoxy Resin

open access: yesJournal of Applied Polymer Science, Volume 142, Issue 21, June 5, 2025.
In this paper, an epoxy is blended with a phosphorus‐based flame retardant, DEPAL (OP935). Several thermomechanical (thermogravimetric analysis, dynamic mechanical analysis, three‐point bending, Charpy impact test) and flammability (cone calorimeter, UL94) methods are used to evaluate the effect of the flame retardant on these performance aspects ...
