Activation of Metal Complexes With Ultrasound Waves for Targeted Anticancer Therapy

Angewandte Chemie International Edition, EarlyView.
Ultrasound enables non‐invasive activation of metal‐based therapeutics deep within tumors. Acoustic cavitation can drive sonodynamic reactive oxygen species generation or mechanochemical metal–ligand bond dissociation, enabling controlled release of bioactive payloads.

A narrow bandgap Schottky heterojunction Fe2N/CeO2 microneedle triggering sonodynamic reactive oxygen species storm for drug‐resistance‐free skin fungal infection

BMEMat, EarlyView.
Inorganic sonosensitizers suffer from inefficient electron‐hole separation, rapid recombination, and wide bandgaps in anti‐fungal applications. We propose MN@Fe2N/CeO2 to directly eliminate fungi without drug resistance. Combining semiconductor CeO2's advantages with Fe2N's high work function and activity enables efficient Schottky heterojunctions ...

An all‐in‐one fucosylated gold nanocluster probe enables NIR‐II imaging and multi‐mechanistic therapy of acute kidney injury

BMEMat, EarlyView.
This study developed a fucoside‐targeted gold nanocluster probe that enables early NIR‐II imaging and multi‐mechanistic therapy for acute kidney injury, effectively mitigating oxidative stress, modulating inflammatory responses, and inhibiting ferroptosis to improve renal outcomes. Abstract Acute kidney injury (AKI) remains a life‐threatening condition

Locking Ni Atoms in Ordered PtNi for Durable Hydrogen Production: From Electrocatalyst Design to Practical AEMWE Stack Validation

Carbon Energy, EarlyView.
DFT‐guided atomic ordering of PtNi intermetallic catalysts enhances HER activity and durability by optimizing hydrogen adsorption and increasing dissolution potential. Experimental validation from half‐cell to practical AEMWE stack demonstrates outstanding performance with less than 2% degradation over 3,000 h.

Coupled Photocatalytic Hydrogen Production With Selective Biomass Valorization via Active Sites Construction and Electron Transport Channels Engineering

Carbon Energy, EarlyView.
A ternary CdS/1T‐WS2/CNTs heterojunction is in‐situ constructed via hydrothermal method, which is used for photocatalytic biomass reforming (biomass‐derived alcohols, lignin). It exhibits outstanding performance: H2 production rate of 26.17 mmol/g/h for benzyl alcohol (BA), benzaldehyde (BD) generation rate of 8.29 mmol/g/h, 90.06% BD selectivity, 100%
