Facets of Crises: How Problem Indicators and Public Perceptions Affect Policy Change
ABSTRACT Crises are widely acknowledged as catalysts for policy change. Yet, our understanding of the policy effects of crises remains limited. Why do only some crises lead to major changes, while significant policy changes also occur during seemingly non‐crisis periods?

VO2 Hollow Nano‐Reactor: Enabling Near‐Room‐Temperature and Ultrafast Hydrogen Release From α‐AlH3
ABSTRACT α‐phase aluminum trihydride (α‐AlH3) is a promising high‐capacity hydrogen storage material, but its practical application is limited by slow dehydrogenation kinetics and high reaction temperatures. This study demonstrates, for the first time, effective modulation of the hydrogen release kinetics of AlH3 by employing a hollow nanostructured ...
