Room‐Temperature Gas‐Phase CO2‐to‐C3 Coupling by a 4f‐Aromatic Cluster

Angewandte Chemie, EarlyView.
We engineered a 4f metalla aromatic cluster, PrB2C2−, that enables efficient sequential C−C coupling with CO2 at room temperature, yielding a linear C3 backbone. This system provides a complete theoretical catalytic cycle and establishes a new design principle for lanthanide mediated CO2 activation.

Synthesis of Highly Crystalline Graphite from Spontaneous Ignition of In Situ Derived Acetylene and Chlorine at Ambient Conditions

Molecules, 2020
We exploited a classic chemistry demonstration experiment based on the reaction of acetylene with chlorine to obtain highly crystalline graphite at ambient conditions. Acetylene and chlorine were generated in-situ by the addition of calcium carbide (CaC2)

One‐Step Radical‐Intensified Selective Etching (RISE) Strategy for High‐Yield Synthesis of Monolayer MXene with Tailored Nanoholes

Angewandte Chemie, EarlyView.
Radical‐intensified selective etching (RISE) delivers monolayer MXenes with >80% yield in just 3 h etching process. Controlled ·OH dosage enables one‐step access to holey MXenes with abundant nanopores or defect‐lean flakes. This mild, safe strategy couple ultrafast kinetics with structural tunability, advancing precision design of MXene architectures.

Advanced Dental Composite Technology via Bisilanized Dual‐Action Nanofillers for Biofilm Control

Advanced Science, EarlyView.
A multimodal research strategy has led to the development of an innovative resin‐based composite (RBC) with dual antibacterial action. The S_CM‐RBC formula showed strong antibiofilm activity, excellent mechanical strength, and biosafety. It effectively controlled oral bacteria in prevention of caries recurrence, and maintained pulp health in a rat ...

Intercalated Rare-Earth Metals under Graphene on SiC [PDF]

, 2018
Intercalation of rare earth metals ($RE$ = Eu, Dy, and Gd) is achieved by depositing the $RE$ metal on graphene that is grown on silicon-carbide (SiC) and by subsequent annealing at high temperatures to promote intercalation.
