Henrique Gasparetto describes how hydrogen temperature-programmed reduction can be used to probe metal–support interactions in catalysts.

An article in Environmental Science & Technology describes the potential effect of technology optimization and decarbonization measures on lithium extraction from brine impacts.

Earth observation can provide key information for planning, operations and independent monitoring with verification but is often underused in energy governance. Earth observation approaches should be embedded in energy policy and technical capacity to leverage this information for the clean energy transition.

Carbon dioxide removal has been described both as a mitigation necessity and as a risk to mitigation ambition or sustainability in the academic literature. This Comment examines the assumptions underlying carbon dioxide removal narratives and investigates whether they are reconcilable to inform the focus of research and policy.

Lan Wen discusses how high-performance liquid chromatography can be used to monitor products and yields in photoelectrochemical systems.

Shwetha Prakash explains how in situ Raman spectroscopy can be used to study electrochemical processes in real time.
