Ultrafast Biodiesel Synthesis via K2CO3‐Supported Mg‐Al Hydrotalcite Catalyst With Tailored Basicity and Mesoporous Structure

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT With the increasing global energy demand and the growing prominence of environmental issues, biodiesel has garnered significant attention as a renewable, low‐emission green energy source. Conventional hydrotalcite‐based catalysts often suffer from insufficient basicity and limited accessibility of active sites, leading to relatively long ...

Mechanochromic Organic Materials: Molecular Mechanisms and Multidimensional Applications

Advanced Physics Research, EarlyView.
Mechanochromic (MC) organic materials change color in response to mechanical force. This review elucidates the molecular mechanisms (e.g., aggregation‐induced emission, AIE) and explores their multidimensional applications in sensors, anti‐counterfeiting, biomedical devices, and structural health monitoring, providing a roadmap for future smart ...
