Mechanochemistry of Pterodactylane
Journal of the American Chemical Society, 2023Pterodactylane is a [4]-ladderane with substituents on the central rung. Comparing the mechanochemistry of the [4]-ladderane structure when pulled from the central rung versus the end rung revealed a striking difference in the threshold force of mechanoactivation: the threshold force is dramatically lowered from 1.9 nN when pulled on the end rung to 0 ...

Journal of the American Chemical Society, 2022
We report the mechanochemical reactivity of the highly strained pentacyclic hydrocarbon cubane. The mechanical reactivity of cubane is explored for three regioisomers with 1,2-, 1,3-, and 1,4-substituted pulling attachments. Whereas all compounds can be activated thermally, mechanical activation is observed via pulsed ultrasonication of cubane ...

Acta Biomaterialia, 2023
The collagen molecular family is the result of nearly one billion years of evolution. It is a unique family of proteins, the majority of which provide general mechanical support to biological tissues. Fibril forming collagens are the most abundant collagens in vertebrate animals and are generally found in positions that resist tensile loading.

The mechanochemistry of cytogels
Physica D: Nonlinear Phenomena, 1984We present a mechanochemical model for force generation by actomyosin cytogel. The model is built around the observation that calcium ions both solate actomyosin gels and stimulate active contraction of the gel. The model cytogel can mimic a variety of morphogenetic pattern-producing phenomena.

Mechanochemistry of Gaseous Reactants
Angewandte Chemie - International Edition, 2019Abstract In recent years, the application of mechanical energy to chemical systems has repeatedly proven beneficial to facilitate chemical transformations in various areas in chemistry. Today, a systematic body of evidence indicates that mechanochemistry holds great promise to become a game‐changer in chemical synthesis. Not only does
