Mechanochemistry Meets Catalysis: Metal Complexes for Greener Organic Transformations
Angewandte Chemie, EarlyView.Mechanochemistry is redefining metal catalysis by controlling catalyst formulation, speciation, and deployment. This Review shows how milling, LAG, RAM, and TSE enable rapid metal‐complex assembly, distinctive catalytic manifolds, and scalable synthesis beyond solution chemistry.

Advanced Science, EarlyView.Tensile‐strained bismuth nanosheets (TS‐BiNs) achieve a formate Faradaic efficiency of 92% at −1000 mA cm−2 and enable stable production of pure formic acid (HCOOH) in a solid‐state electrolyte reactor. Theoretical calculations reveal that the introduced strain lowers the energy barrier for *OCHO intermediate formation, fundamentally enhancing the ...

Structural and magnetic properties of mechanochemically synthesized nanocrystalline titanium monoxide [PDF]
, 2012 Nano-sized titanium monoxide (TiO) powder was prepared by mechanochemical synthesis. A mixture of commercial Ti and TiO2 (rutile) powders with the molar ratio of 1:1 was milled in a planetary ball mill for 5, 10, 20, 30 and 60 min under argon atmosphere.

Angewandte Chemie, EarlyView.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.

Mechanically Regulated Nanozymes for Remote Metabolic Reprogramming and Precise Cancer Therapy
Angewandte Chemie, EarlyView.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
