Enlarged‐TriQuinoline (Enl‐TQ): Disparity in Chemical Behaviors by Geometric Scaling of the Trimeric Quinoline Ring System

Chemistry – An Asian Journal, EarlyView.
TriQuinoline (TQ), a quasi‐planar cyclic quinoline trimer in a head‐to‐tail arrangement, strongly captures a proton and exhibits unusual physicochemical properties. In this study, we designed and synthesized its expanded analog, Enlarged‐TriQuinoline (Enl‐TQ), in which three alkyne units are embedded between three quinoline units to acquire an expanded

Engineering Photolabile Cyclopentane‐Fused Coumarins: From One‐Pot Synthesis to Mechanistic Study for Visible Light‐Triggered Photolysis

Chemistry – An Asian Journal, EarlyView.
Cyclopentane fusion in coumarin photocages transforms their behavior from rapid SN1‐mediated release (minutes) to a slower elimination pathway (hours), accompanied by dramatic spectral changes upon photolysis, providing complementary tools for controlled‐release applications requiring different payload delivery rates.

Biochar in the circular bioeconomy: a bibliometric analysis of technologies, applications, and trends

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Biochar has attracted considerable attention in recent years for its wide‐ranging applications, particularly its role in carbon sequestration as a strategy to mitigate greenhouse gas emissions. Its emerging uses within the circular bioeconomy also position it as a valuable tool for environmental management, and ongoing research continues to ...
