Mechanically induced pyrogallol[4]arene hexamer …

The first example of milling induced guest encapsulation, appearing in 2016, is Szumna's use of ball milling to facilitate the encapsulation of C 60 or C 70 in peptidic, dimeric molecular capsules based on a resorcin[4]arene platform. 11 Milling facilitated quantitative complexation, but the same encapsulation complexes could be prepared also ...

Ball milling induced crystallization of amorphous Fe90Zr10 ...

Crystallization of amorphous Fe 90 Zr 10 under ball milling may be either a deformation-induced process or linked to local temperature rises during ball collisions. At low milling speeds such as 300 and 400 rpm the temperature rise under milling is presumably not more than 200 °C following the results of ref. . Hence, thermally induced ...

Ball milling induced the formation of nanocrystalline and amorphization phase in Fe–25.68% Dy2O3 powder mixtures (mass fraction, %). The microstructure was investigated by using X-ray diffraction and transmission electron microscopy. The transformation of Dy2O3 from cubic to monoclinic crystal structure and then to the amorphization was observed during ball milling. A few Dy atoms were ...

Self-sustaining reactions induced by ball milling ...

Ball milling induces self-sustaining reactions in many sufficiently exothermic powder mixtures. The process begins with an activation period, during which size reduction, mixing, and defect formation take place. The MSR (mechanically induced self-propagating reaction) is ignited when the powder reaches a well defined critical state.

Ball mass is an important parameter that is known to have an influence on the outcome of a mechanochemical reaction induced by ball-milling. A standard way of modifying the ball mass is to change the size of the ball made of the same material. In this case, however, a change in mass is accompanied by a simul Editor's Collection: Mechanochemistry The Solid State of Pharmaceuticals

A set of Bragg peaks consistent with a hexagonal Bravais lattice was observed in the x-ray powder diffraction pattern of cubic pyrochlore rubidium tungstoniobate (RbNbWO6) subjected to high-energy ball milling. The calculated lattice parameters for this hexagonal phase are similar to those of compounds with tungsten bronze structure. In fact, the powder pattern of the hexagonal phase could be ...
