· Mechanism of ball millinginduced crystallization Temperature. In order to understand the mechanism of mechanical deformationinduced nanocrystal formation in amorphous alloys, it is useful to review some aspects of the solidstate amor phization by mechanical alloying or ball milling .
The aim of this study was to compare three different analytical methods to detect and quantify the amount of crystalline disorder/ amorphousness in two milled model drugs. Xray powder diffraction (XRPD), differential scanning calorimetry (DSC) and Raman spectroscopy were used as analytical methods and indomethacin and simvastatin were chosen as the model compounds.
A feasible approach for the production of xylose and xylooligomer from corncob was developed using oxalic acidassisted ball milling, followed by the microwaveinduced hydrothermal treatment. Parameters such as milling time, the amount of oxalic acid, hydrothermal treatment time and temperature were evaluated. Results showed that most of hemicelluloses in the cell wall could be .

Phase transformation induced by ballmilling was studied in this work. It was found that amorphous Fe90Zr10 ribbons undergo crystallization into BCC αFe(Zr) under milling in an AGO2 mill. The decomposition degree of the amorphous phase increased with increasing milling time and intensity. Analyses of samples milled at different speeds suggested that the observed crystallization is a ...

Mechanical alloying using a highenergy ball milling technique was used to fabrie a single glassy phase of Zr 70 Pd 20 Ni 10 alloy powders after 100 h milling time. Annealing the glassy powders at a temperature just below the crystallization onset temperature led to thermally enhanced devitrifiion and the formation of a metastable bigcube phase with a lattice constant of nm.

· For 2 hour ball milling time, less defects are induced thus less nuclei form, favoring relatively high growth rate along the <001> (FIG. 4c ), whereas more defects induced by 10 hour ball milling increase the number of nuclei at the interface, so that the growth along the <00l> orientation is retained, enabling the relatively high growth rate along
· 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 resorcinarene platform. 11 Milling facilitated quantitative complexation, but the same encapsulation complexes could be prepared also by refluxing solutions of host and guest.
