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...

The scientific community’s general interest in using mechanical energy to trigger or facilitate chemical reactivity has been growing at a speedy pace. In particular, in recent years, organic chemistry has witnessed a constant flow of examples where the use of mechanochemical techniques proved not only to outperform traditional solution-based methodologies, but also enabled access to otherwise i...

Mechanochemical reactions often result in 100% yields of single products, making purifying procedures obsolete. Mechanochemistry is also a sustainable and eco-friendly method. The ever increasing interest in this method is contrasted by a lack in mechanistic understanding of the mechanochemical reactivity and selectivity. Recent in situ investigations provided direct insight into formation path...
