Sep 20, 2021Sep 20, 2021However, the porosity of all ball-milled samples could be developed after annealing, as a result of new pore formation and partial volatilisation of carbon moieties and surface-adsorbed Sn. This effect was more noticeable when the annealing temperature increased from 500 to 750 C, whereas the samples annealed at 900 C displayed only small
In this work, we report using ball-milled low-cost silicon (Si) as the starting material and subsequent carbon coating to produce low-cost hierarchical carbon-coated (HCC) Si. The obtained particles prepared from different Si sources all show excellent cycling performance of over 1000 mAh/g after 1000 cycles.

Mar 23, 2021The wet grinding of the ball mill means that when the material enters the ball mill, it will be ground under the interaction of the alumina ball and the material itself to meet the needs of customers. In this process, there will also be liquids, such as water. The movement of material is in the ball mill needs to be driven by the liquid (water).
Ball milled activated carbon from the experiment had a pore radius ranging from 1.18 to 2.49 nm. The activated carbon that met the criteria of ANSI/AWWA B604-12 (2021) standard for moisture content, iodine number, and JIS K 1474 (1967) standard for methylene blue adsorption level and surface area were milled activated carbon with activator
Mar 25, 2021Mar 25, 2021Copper-doped BiVO4 nanoparticles were synthesized by a mechano-chemical method under optimized conditions to obtain a monoclinic scheelite structure. The crystal structure and its evolution with doping were investigated by X-ray powder diffraction, micro-Raman spectroscopy, field emission scanning electron m Editor's Collection: Mechanochemistry
ball-milled for 10 min. In contrast to the as-grown materials where entangled SWNT bundles are re-solved Fig. 2C, only densely-packed particles were . observed in the ball-milled materials at low resolu-tion. Close examination along the edges of these particles showed individual nanotubes and small SWNT bundles Fig. 2D,E . Observation of many .
Mar 01, 2021Mar 01, 2021Ball milled sugarcane bagasse biomass pyrolyzed at 450C (BMBG450) had the highest methylene blue sorption capacity thus was chosen for further study. Compared to unmilled bagasse biochar (BG450), BMBG450 had greater specific surface area, larger pore volume, smaller hydrodynamic radius, stronger negative zeta potential (about 1.6-fold increase

In this study, high-energy ball milling and high frequency induction sintering (HFIS) were used to produce bulk samples with refined microstructure. EXPERIMENTAL PROCEDURE The used material was a commercial aluminum powder (99.5% purity, -325 mesh); Al was milled in a high-energy ball mill (Spex 8000M) for 2h to produce
Selective laser sintering (SLS) is an additive manufacturing (AM) technique that uses a laser as the power source to sinter powdered material (typically nylon or polyamide), aiming the laser automatically at points in space defined by a 3D model, binding the material together to create a solid structure.It is similar to selective laser melting; the two are instantiations of the same concept

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
Characterization of microstructure, hydrogen storage
May 17, 2021May 17, 2021The coarse surface and refined particle in the ball-milled sample is favorable to the hydrogen absorption and desorption performances . To further characterize the microstructure of ball-milled Mg 90 Y 1.5 Ce 1.5 Ni 7 samples, the FETEM and corresponding SAED were analyzed by TEM, as presented in Fig. 2(d), (e), and (f
