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

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.

Although the history of mechanochemistry goes back centuries, with the rapid growth of articles about it, it is becoming clear that this once arcane discipline is becoming increasingly useful.

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 for Synthesis
Angewandte Chemie, 2019AbstractMechanochemical solvent‐free reactions by milling, grinding or other types of mechanical action have emerged as a viable alternative to solution chemistry. Mechanochemistry offers not only a possibility to eliminate the need for bulk solvent use, and reduce the generation of waste, but it also unlocks the door to a different reaction ...

Mechanochemistry: The Effect of Dynamics
The Journal of Physical Chemistry A, 2014Dynamical effects on the mechanochemistry of linear alkane chains, mimicking polyethylene, are studied by means of molecular dynamics simulations. Butane and octane are studied using density-functional theory (DFT), whereas higher homologues are studied using a simple one-dimensional model in which the molecules are represented by a linear chain of ...

The Mechanochemistry of Kinesin
Molecular and Chemical Neuropathology, 1990The mechanochemical protein kinesin is believed to play an important role in intracellular vesicle movements, including the anterograde motion of axoplasmic transport. This article reviews some of the pharmacological and biochemical information about kinesin, particularly with respect to the properties of nucleotide-dependent microtubule binding ...
