Advanced Functional Materials, EarlyView.Electrochemical abuse transforms thermal runaway behavior in lithium‐ion batteries. Through systematic decoupling of degradation mechanisms, this study reveals that lithium plating lowers the onset temperature by 10 °C, electrolyte consumption delays high‐temperature reactions, and capacity fade reduces total heat generation. These mechanistic insights

Mesoporous Carbon Thin Films with Large Mesopores as Model Material for Electrochemical Applications
Advanced Functional Materials, EarlyView.Mesoporous carbon thin films possessing 70 nm mesopores are prepared on titanium substrates by soft templating of resol resins with a self‐synthesized poly(ethylene oxide)‐block‐poly(hexyl acrylate) block copolymer. A strategy to avoid corrosion of the metal substrate is presented, and the films are extensively characterized in terms of morphology ...

Introducing Pure Calcium Orthophosphate Gels and Aerogels
Advanced Functional Materials, EarlyView.The synthesis of calcium phosphate‐based gels and aerogels is reported, which exhibit highly porous structures built up of networks of nanoparticles. In case of amorphous aerogels, this leads to yet unmatched specific BET surface areas, making these materials especially interesting for biomedical applications.

Carbon Neutrality and Bioenergy: A Zero-Sum Game? [PDF]
Biomass, a renewable energy source, has been viewed as “carbon neutral”—that is, its use as energy is presumed not to release net carbon dioxide. However, this assumption of carbon neutrality has recently been challenged. In 2010 two letters were sent to
