One‐Step, High‐Yield Deconstruction of Kraft Lignin Into a Redox‐Active Small Molecule Using Sonicated Emulsive Water Microdroplets

open access: yesSmall, EarlyView.
This study reports a rapid (∼20 min), uncatalyzed deconstruction of Kraft lignin (∼14.2 kDa) using sonicated emulsive water microdroplets (SEWMs) in the presence of 2.5 M HNO3. The work demonstrates the combined synergistic effect of sonochemical excitation and microdroplet redox chemistry to induce C─C bond cleavage and reductive nitration to ...

A Dynamic Surface Metal‐Organic Framework Electrocatalyst: Potential‐Driven Activation of Atomically Defined Au Sites for the Hydrogen Evolution Reaction

open access: yesSmall, EarlyView.
Operando EC‐STM reveals that an NHC‐based SMOF on Au(111), initially frozen in interconnected 1D chains, dynamically reconfigures under cathodic bias into a fluxional structure bearing undercoordinated Au sites while abstracting Au atoms from the support.

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

open access: yesSmall, 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 ...

Synthesis, modification, and chlorhexidine loading of polymer modified‐HM‐HAP particles: In vivo antibacterial analysis and cell cytotoxicity assessment

open access: yesSmart Molecules, EarlyView.
This study presents the synthesis of hollow mesoporous hydroxyapatite (HM‐HAP) particles modified with different weights PEG and PEI. Chlorhexidine was loaded onto the particles. SEM analysis confirmed no significant morphological changes. Antibacterial activity was tested in vitro and in vivo using mouse oral bacteria, demonstrating promising results.
