Ammonium Salts as Curing Agents to Obtain Ionic Epoxy Resins With a Thermoplastic‐to‐Thermoset Transition

open access: yesAdvanced Materials, EarlyView.
Ionic epoxy networks are prepared using ammonium salts as hardeners, leading to a two‐stage curing process with a thermoplastic‐like intermediate. This uncommon behavior enables extrusion and fabrication of thermoplastic prepregs that can be cured into thermoset composites.

Recent Studies on DNA Adducts Resulting from Human Exposure to Tobacco Smoke

open access: yesToxics, 2019
DNA adducts are believed to play a central role in the induction of cancer in cigarette smokers and are proposed as being potential biomarkers of cancer risk. We have summarized research conducted since 2012 on DNA adduct formation in smokers.

De Rerum Natura: How Do Halide Perovskites Self‐Heal From Damage?

open access: yesAdvanced Materials, EarlyView.
How can lead‐halide‐perovskites self‐heal after damage from light, heat, mechanical strain, or radiation? We show that reversible chemical defects underly performance losses and recovery, highlighting the roles of halide and proton migration, redox‐driven reactions, and acid‐base equilibria.

Inter‐Atomic Synergy on Single‐Atom Alloy Promotes Cyclohexanone Oxime Electrosynthesis

open access: yesAdvanced Materials, EarlyView.
Electrosynthesis of cyclohexanone oxime using renewable electricity offers a greener alternative to traditional energy‐intensive methods. Here, we develop a Fe1Bi single‐atom alloy that delivers 70.9% Faradaic efficiency and 0.94 mmol cm−2 h−1 yield rate through the atomic‐scale synergistic mechanism.
