Phase Evolution and Compositional Homogenization in Mechanochemically Activated High‐Entropy Manganite Perovskites

Journal of the American Ceramic Society, Volume 109, Issue 8, August 2026.
ABSTRACT The synthesis of single‐phase La0.35Gd0.35Ca0.3(Mn0.5Co0.1Cu0.1Fe0.1Ni0.1Mg0.1)O3 high‐entropy perovskite oxides was investigated using mechanochemical activation followed by thermal treatments. The influence of milling time (1–150 h) and post‐milling annealing temperature on phase formation, compositional homogeneity, and structural evolution

Tailored Nanogel Network Topology Enables Clinical Ultrasound‐Induced Mechanochemical Activation for In Vivo Therapy

Angewandte Chemie, Volume 138, Issue 30, 20 July 2026.
The strategy of engineering nanogel network topology is developed to achieve iterative activation of mechanophores upon high‐frequency and low‐intensity ultrasound. This places the nanogel system among the systems that can respond to the ultrasound with the highest frequency and lowest intensity as well as have the fastest activation rate so far.

Kinetic Insights Into Boron–Carbon Interaction Under Programmed Heating

Journal of the American Ceramic Society, Volume 109, Issue 8, August 2026.
This work demonstrates the decisive role of the heating rate and short‐term mechanical activation in governing the boron–carbon interaction. The combined effect of rapid heating and mechanical activation enables the 4B + C reaction to proceed at significantly lower temperatures. For the first time, the effective activation energy of the 4B + C reaction

Mechanically Regulated Nanozymes for Remote Metabolic Reprogramming and Precise Cancer Therapy

Angewandte Chemie, Volume 138, Issue 30, 20 July 2026.
Inspired by mechanoenzymes, a ferrocene‐based mechanically regulated nanozyme converts acoustic shear force into enhanced peroxidase‐like activity by decreasing electron density and alleviating steric hindrance at the Fe active sites, thereby rewiring redox homeostasis. Leveraging this remote regulatory mechanism, a multienzyme‐regulated nanoreactor is

Identification of Pyrazolidine‐3‐One Derivatives as a Novel Structural Scaffold for ATP Synthase Inhibitors

ChemMedChem, Volume 21, Issue 14, 29 July 2026.
Following the discovery of oxadiazin‐5‐ones as partial inhibitors of the ATP synthase, we herein report the synthesis of a library of pyrazolidine‐3‐ones and pyrazol‐3‐ones, designed by reducing the six‐membered N–N heterocycles to five‐membered rings.

Influence of Si Content and Milling Duration on the Microstructure and Mechanical–Tribological Properties of AlCoCrFeNiSi High‐Entropy Alloys

Advanced Engineering Materials, Volume 28, Issue 14, 22 July 2026.
Si‐doped AlCoCrFeNi high‐entropy alloys are synthesized by mechanical alloying to reveal the effect of Si content and milling time on phase evolution, microstructural refinement, and tribological behavior. A transition from FCC to BCC structure, significant grain refinement, and enhanced hardness and wear resistance are achieved, with the 4 at% Si ...
