Mechanochemistry makes the next move in advancing organometallic synthesis. In their Research Article (e202305775), Riina Aav, Dzmitry G. Kananovich et al. report a mechanochemical adaptation of Mg-mediated Barbier reaction, which overcomes limitations classic solvent-based approach. Mechanochemical activation enables rapid generation Grignard reagents situ, making process resistant to air and ...

        Synthetic hydroxyapatite (HA) is the most helpful because of its similarity to natural bone in both crystalline structure and chemical composition. Recently, fluoridated hydroxyapatite (FHA) has been developed in dental and orthopedic application because it has lower solubility than pure HA, while maintaining the comparable bioactivity and biocompatibility. The aim of this study was to...

Chemical and structural transformations have long been carried out by milling. Such mechanochemical steps are now ubiquitous in a number of industries (such as the pharmaceutical, chemical and metallurgical industries), and are emerging as excellent environmentally friendly alternatives to solution-based syntheses. However, mechanochemical transformations are typically difficult to monitor in r...

Regarding the activation of chemical reactions, today’s chemist is used to thinking in terms of thermochemistry, electrochemistry, and photochemistry, which is reflected in the organization and content of the standard physical chemistry textbooks. The fourth way of chemical activation, mechanochemistry, is usually less well-known. The purpose of the present review is to give a survey of the cla...

The mechanochemical preparation of highly functionalized 3,5-disubstituted hydantoins was investigated in the presence of various poly(ethylene) glycols (PEGs), as safe grinding assisting agents (liquid-assisted grinding, LAG). A comparative study under dry-grinding conditions was also performed. The results showed that the cyclization reaction was influenced by the amount of the PEG grinding a...

We revealed the processes for activation, mechanically induced self-sustaining reaction (MSR) and crystal growth of Ag in mechanochemical reduction AgCl with Al by situ synchrotron X-ray diffraction.

Mechanical activation in mechanical removal of GaN using diamond tip and mechanochemical Al2O3 are described by the Archard equation mechanically assisted Arrhenius-type kinetic model, respectively. Evident material-removal under elastic contact occurs with assistance interfacial reactions. By analyzing reactions model Hertzian mechanics, critical volume barrier determined semiquantitatively. T...
