This study prepared compression-molded products from ball-milled wood by thermally plasticizing lignin without adhesives or resins. Wet ball milling for 120 min produced smooth, creamy slurries. The resultant products were hot-pressed at 180 °C and exhibited a plastic-like glossy surface and a high Young's modulus (7.9 GPa), which was ...

Ball-milled material showed an increase in porosity and was significantly more compactible than the unmilled granulation from the same batch. Conclusions: The decrease in MCC compactibility after granulation is associated with the decrease in MCC primary particle porosity and in some cases with the formation of large dense granules as well.

hand, in ball milled systems, high amount of PP results very low crystallinity in HDPE. An inverse relation between crystallinity content of polymers, as PP amount increases, can be figured out. The change in HDPE crystallinity is more clear. 4.CONCLUSIONS : In this study effect of ball milling on HDPE and PP mixtures were examined.

In this study, an advanced Sn-functionalised biochar catalyst was synthesised via a novel solvent-free ball milling protocol to facilitate the isomerisation of glucose to fructose. Raw wood biomass (W) and its derived biochars pyrolysed at low (LB, 400 °C) and high (HB, 750 °C) temperatures were investigated as catalyst supports.

12%In the present study, we observed the several major physical and chemical changes of milled fly ash during the high-energy ball-milling process. Significantly, large particles of the original fly ash, regularly in an average of 5 μm, were broke down into much smaller particles, in an average particle size of about 300 nm.

The results of the line broadening analysis, performed using Rietveld refinements of the ball-milling products with powder-to-ball weight ratio (R) 1:10, indicated a decrease in the crystallite size and an increase in the microstrains with an increase in the ball-milling time up to 3 h.

The study confirms that the ball milled h-BN could be used as a holes transfer promoter for ZnO. However, the finial photocatalytic performance of h-BN/ZnO is determined by the superposition of the two effects for a specific degradation process. This is the reason why the enhancement of ball milled h-BN is only effective for cationic dyes.

To study the effects of ball milling on hydrogen mobility in TiH2 with C, B, and BN additives, we have measured the 1H and 11B nuclear magnetic resonance (NMR) spectra and spin−lattice relaxation rates in these nanostructured systems over the temperature range 11−384 K. It is found that for the ball-milled TiH2 without any additives and with C and B additives, the hydrogen jump rates ...
