An alternative strategy for the mechanochemical defluorinative acylation of ortho-hydroxyarylenaminones has been developed to synthesise 3-acylchromones utilizing CF3-compounds via activation C−F bound trifluoromethyl group in presence ytterbia (Yb2O3). The current protocol tolerated a wide range coupling substrates access library diversely substituted under mechanochemically induced domino cyc...

Silver, Frederick H., Dale DeVore, and Lorraine M. Siperko. Invited Review: Role of mechanophysiology in aging of ECM: effects of changes in mechanochemical transduction. J Appl Physiol 95: 2134–2141, 2003; 10.1152/japplphysiol.00429.2003.—Mechanical forces play a role in the development and evolution of extracellular matrices (ECMs) found in connective tissue. Gravitational forces acting on ma...

Three Bi-doped vanadyl pyrophosphate catalysts were prepared via dihydrate route (VPD method), which consisted of different preparation methods including mechanosynthesis, mechanochemical treatment, and the conventional reflux method. The catalysts produced by the above three methods were characterized by x-ray diffraction (XRD), scanning electron microscopy (SEM), and temperature programmed re...

Mechanophore-linked linear poly(methyl methacrylate) (PMMA) was synthesized using bisfunctionalized spiropyran (SP) as an atom transfer radical polymerization initiator. The resulting polymer had a Tg of 127 C and molecular weight greater than 250 kDa. SP-cleavage experiments confirmed the incorporation of SP molecules approximately into the center of the polymer chain. Force-induced reaction o...

The effect of mechanical milling on the thermal behavior pyrophyllite ore from a deposit in Parsovici, Bosnia and Herzegovina, was characterized by X-ray powder diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy, Particle size distribution. material followed thermogravimetric differential analysis correlated to its microstructural properties. Williamson-Hall mode...
