Oct 29, 2021 · The powders were ball milled in a zirconia (ZrO 2) jar ( L), using zirconia balls in an ambient atmosphere; the mechanical milling was performed in a ball mill, model S/1 1000B (Ceramic Instruments, Sassuolo Modena, Italy), operating at 390 rpm. The particles were finely reduced to nanometric scale thanks to the highenergy collisions ...
Aug 16, 2017 · Following incubation in normal mouse serum, quantitative labelfree mass spectrometry identified differences in the biomolecular content of the BC resulting from the ballmilling process. Further, incubation in cholesterolrich mouse serum resulted in the formation of unique BCs compared to SWCNTs incubated in normal serum.
Processing science for nanocrystalline metals has largely focused on farfromequilibrium methods that can generate many grain boundaries with excess defect energy. Conversely, the science of stabilizing nanocrystalline alloys has largely focused on the lowering of that excess defect energy through grain boundary segregation, bringing nanocrystalline structures closer to equilibrium. With ...
