Discrete One-Stage Mechanochemical Synthesis of Titanium-Nitride in a High-Energy Mill
Metals, 2021 Discrete (discontinuous) mechanochemical synthesis of titanium nitride was experimentally investigated. The experimental results show that mechanical activation intensifies the chemical conversion in the Ti-N system, and the discrete synthesis of the ...

On the mechanochemical activation by ultrasound [PDF]
Chemical Society Reviews, 2013 Chemists have discovered, and recently actively exploited, the fact that subjecting certain molecules to ultrasound waves can bring about transformations that give insight into the correlation between classical tribological processes and the mechanical action caused by collapsing microbubbles when sonic waves propagate through a liquid medium. Chemical

Mechanochemical ATPases and transcriptional activation [PDF]
Molecular Microbiology, 2002 SummaryTranscriptional activator proteins that act upon the σ54‐containing form of the bacterial RNA polymerase belong to the extensive AAA+ superfamily of ATPases, members of which are found in all three kingdoms of life and function in diverse cellular processes, often via chaperone‐like activities.

A Polymer with Mechanochemically Active Hidden Length [PDF]
Journal of the American Chemical Society, 2020 Incorporating hidden length into polymer chains can improve their mechanical properties, because release of the hidden length under mechanical loads enables localized strain relief without chain fracture. To date, the design of hidden length has focused primarily on the choice of the sacrificial bonds holding the hidden length together.

Mechanochemical bond scission for the activation of drugs
Nature Chemistry, 2021 Pharmaceutical drug therapy is often hindered by issues caused by poor drug selectivity, including unwanted side effects and drug resistance. Spatial and temporal control over drug activation in response to stimuli is a promising strategy to attenuate and circumvent these problems.
