XRD showed that the peaks of α-Fe 0 (PDF#06–0696) are located at 2θ = 44.67°, 65.02°, and 82.33°, and α-Fe 0 is the dominant phase in all modified particles (Fig. 1 l). The N or Ni doping modification did not cause significant changes in the crystalline phase of mZVI particles, and the characteristic diffraction peaks of Ni or melamine were not detected.
Mechanochemical sulfidation is a facile and promising approach for sulfidating microscale zero-valent iron (mZVI). Compared to simple ball-milling of mZVI that reduces particle size and exposes reactive Fe 0 surface, ball-milling of mZVI with S 0 results in sulfidation and at the same time greater size reduction [15].The rate and electron efficiency of TCE …

To prepare the ball-milled biochar (BMBC), typically, 10 g of BC was placed into ball grinder with zirconium oxide jars and milled at 1600 rpm for 30 times (each run for 60 s). The nal product, ball-milled biochar, was marked as BMBC. 2.3 Batch adsorbing experiments The effect of biochar dosage on Pb(II) and sorption was tested
Smaller ball-milled seeds exhibited better induction effect for membrane crystallization. When using the ball-milled seeds with average particles size of ∼0.3 μm, high quality of NaA zeolite membrane could be synthesized at 373–383 K for 4 h. The ball-milling method for preparing submicron-size NaA zeolite seed is of high productivity ...
Enhanced superconducting properties in bulk MgB 2 through spark plasma sintering of ball‑milled and sieved crystalline boron Malik Shadab1, Yiteng Xing 2, Jacques Noudem2, and Muralidhar Miryala1,* 1 Materials for Energy and Environmental Laboratory, Graduate School of Engineering and Science, Shibaura Institute of Technology,
The equivalent creep properties between powder source samples and wrought ones suggest that powder metallurgy is a viable approach for attaining equivalent high temperature properties in the refractory metals and alloys [2], [3]. Ball-milling is one of various techniques for the synthesis of nanocrystalline alloys.
The mixture was then ball-milled for 2 h at 400 rpm using a planetary ball mill (QM-3SP04, Nanjing University, China). Finally, the powder was collected and dried at 80 °C for 12 h. Pristine g-C 3 N 4 underwent the same balling procedure was also prepared and used as the reference for the comparison of the characterization and HER test results.
grinding bowl and balls made up of stainless steel (316L) and zirconium dioxide. We show that the type of materials employed as grinding bowls and balls can produce nanographite with large disparities in their metallic contents. The catalytic abilities of these two types of ball-milled sulfur-
Various operational factors of ball milling can alter the properties of ball-milled biochar. For example, Peterson et al. (2013) described that media-to-biochar mass ratio and solvent properties for ball milling process were proportional to the surface area of resultant biochar. The ultrafine biochar did not show limitation of high dispersion ...

Finally, the solid material obtained after centrifugation and washing with Milli-Q water was dried in a freeze-drying vacuum oven at − 50 ℃ and named as LDH. To prepare the ball-milled LDH, 3.0 g LDH was accurately weighed and placed into a grinding jar with a planetary ball miller operating at the speed of 500 rpm for 6 h.
The LaSi as-cast ingot was ground to powder and mixed to Fe, Co and Si powders. The ball milling was performed in a planetary Fritsch P7. The as-milled powders were sealed in a silica tube under argon and annealed at 1150 (^circ ) C for 30 min. Moreover, a few part of the as-milled powder was sintered using "Sinter 515S Syntex machine" at temperature …
High-energy ball milling was employed to fabricate LiMnPO 4 coated with varying carbon ratios (3%wt, 7%wt, and 10%wt), using glucose as a carbon source. The process involved pre-milling of LiMnPO 4 precursors, followed by granulation through high-energy ball milling at 270 rpm for 2 h, and subsequent calcination at 700 °C without an inert gas flow. .
