Surface Engineering of Ti3C2Tx MXenes via Silanol Functionalization for Improved Electrochemical Performance

Small, EarlyView.
This study explores the covalent functionalization of Ti3C2Tx using 5,5′‐bis(triisopropoxysilyl)‐2,2′‐bipyridine in different solvents, revealing that only m‐xylene enables effective covalent bonding, ensuring structural stability and preventing layer swelling.

Rhodium Cluster Catalysts Enable Efficient Catalytic Hydroformylation in Mild Conditions: Cluster Size Dependence

Small, EarlyView.
Nanometer‐sized Rh clusters provide a specific reaction environment that facilitates the balanced co‐adsorption of styrene, CO, and H, thereby promoting hydroformylation. ABSTRACT The size of the reactive metal domain, termed an ‘ensemble’, in supported metal catalysts critically influences their catalytic activity.

Sprayable MXene Hydrogels With Composition‐Driven Interfacial Stabilization and on‐Skin Gelation for Conformal Postsurgical Photothermal Therapy

Small, EarlyView.
A sprayable MXene‐loaded thermosensitive hydrogel was developed for postoperative melanoma treatment. Molecular simulations combined with experimental analyses demonstrated that polymer composition regulates MXene oxidation. The optimized hydrogel effectively preserved photothermal performance under physiological conditions, enabling efficient near ...

Ultrafast Mechanochemical Synthesis of Plasmonic Transition Metal Nitride Nanoparticles

Small, EarlyView.
Mechanochemistry enables ultrafast synthesis of plasmonic transition metal nitride nanoparticles in minutes rather than hours without external heat supply. The resulting mono‐ and mixed‐metal nitrides display tunable plasmonic absorption, demonstrating a potentially scalable route to refractory plasmonic materials.
