Bio‐Derived Carbon Nanoparticles: A Green Amendment for Alleviating Heavy Metals in Soil–Plant Systems

Land Degradation &Development, EarlyView.
ABSTRACT Heavy metal (HM) contamination of soil–plant systems poses persistent ecological and health risks, driving interest in nanoparticle‐based remediation. Although conventional chemically synthesized nanoparticles (CSNPs) are effective, their energy‐intensive production and residual toxicity limit sustainable deployment.

Dimensionality‐Driven Carbon Reconstruction Activates MXene Quantum Dots for Dechlorination

Small, EarlyView.
Finite Ti2CO2${\rm Ti}_2{\rm CO}_2$ MXene quantum dots exhibit a reconstruction‐induced activation mechanism absent in extended two‐dimensional MXenes. Carbon‐sublattice reconstruction generates electronically active motifs that facilitate charge redistribution and promote dechlorination of chlorinated hydrocarbons, revealing a new route for activating
