Functionalization‐Mediated Synthesis of Bridge‐Coordinated Fe Atoms on MoS2 Nanosheets for PEM Water Electrolyzers

open access: yesAngewandte Chemie, EarlyView.
We report a functionalization‐mediated strategy to synthesize robust iron (Fe) atoms selectively coordinated at bridge sites on molybdenum disulfide (MoS2) nanosheets. The resulting b‐Fe‐MoS2 catalyst exhibits enhanced activity and durability for the hydrogen evolution reaction in proton exchange membrane water electrolyzers compared to atop ...

Electrochemically Triggered Supramolecular Polymerization Under Kinetic Control

open access: yesAngewandte Chemie, EarlyView.
Chemical and electrochemical stimuli enable controlled supramolecular polymerization of perylene diimide–histidine (PDI–His). Redox processes mediate the transformation of kinetically trapped aggregates into thermodynamically stable nanofibers, thereby supporting seeded growth. This approach provides a strategy for regulating self‐assembly pathways and

Seismic Effect Produced by Detonation of Air-Fuel Mixture in a Borehole

Journal of Mining Science, 2003
Using laboratory, field, and numerical experiments, it is shown that detonation of air-fuel mixture in borehole located in dense rocks is an effective method for generating the transverse seismic wave. Different operation regimes are investigated, and the seismic efficiency is determined for the method in question.
