Ball milling was performed with a Spex 8000 mill with hardened steel vial and balls. The temperature obtained during cryo-milling was estimated to be 85 K by Klassen et al. . Thereafter we refer to this temperature as LN2. The powders were first pre-alloyed by milling at room temperature for 24 h, and then milled for 5 h at low temperature.

The characterization of guaiacyl (G) and syringyl (S) units in the switchgrass ball-milled lignin was identified by the peaks in the regions δ 125–110 and δ 109–103 ppm, respectively. Higuchi et al. has reported that grass lignins are composed of syringyl, guaiacyl, and p -hydroxyl phenyl units and considerable proportion of p -coumaric ...

Saquinavir is an anti-retroviral drug with very low oral bioavailability (e.g. 0.7-4.0%) due to its affinity toward efflux transporters (P-gp) and metabolic enzymes (CYP3A4). The aim of this study was to characterize the effects of high-energy ball milling on saquinavir solid-state characteristics a …

The XRD powder patterns recorded from unmilled and ball-milled (BPMR=40:1) homogeneous powder mixtures are shown in Fig. 1.The powder pattern of unmilled mixture contains only the individual reflections of NiO (ICDD PDF #04-0835), ZnO (ICDD PDF #36-1451), and α-Fe 2 O 3 (ICDD PDF #33-0664) phases only. It is evident from the figure that in the …

Effect of ball-milled treatment done by high-frequency oscillatory-type mill for different time on structure and antiobesity of konjac flour was investigated. Konjac flour granules became smoother and remained its original shape in the first 1.5 h treatment, however its grain size changed from 657.3 (d50) to 23.7 μm (d50) after 4 h treatment, which meant that the …

Ball-milled and enzyme lignins were isolated from the trunks of oil palms and subsequently studied. The lignins were fractionated into pure milled lignin (PML), pure enzyme lignin (PEL), lignin rich enzyme lignin (LREL), hemicellulose rich milled lignin (HRML), and solubilized lignin obtained during enzyme treatment (SLET) fractions by a two-step …

Homogenous Ni–Al2O3 nanocomposite powders with uniform distribution of Al2O3 nanoparticles were obtained through ball milling of Ni and Al2O3 powders for 9 hours. Field emission scanning electron microscopy and X-ray mapping were used to characterize the ball milled powders and Al2O3 nanoparticles' dispersion, respectively. The evolution of crystallite …

The phase transformation kinetics of high-energy ball-milled monoclinic ZrO2 have been studied in detail by Rietveld powder structure refinement analysis. In the present study, no stabilizing compound was required to obtain the cubic phase. The fine-grain powder was milled in a planetary ball mill for up to several hours at different BPMRs (ball to powder mass ratios): …

Microstructure characterization of unmilled, ball milled and post-annealed samples of CaO and a-TiO 2 equimolar powder mixture clearly reveals the following important features: (i) Orthorhombic polymorph of CaTiO 3 in nanocrystalline form can be obtained by ball milling the equimolar powder mixture of CaO and a-TiO 2. (ii)
