In this study, we investigated the effect of the sulfur content in the NiCl2 precursor on the shape of nickel nanoparticles (NiNPs) prepared by chemical vapor synthesis. We obtained spherical NiNPs when using anhydrous NiCl2 mixed with NiSO4 or Na2SO4 with a molar ratio of as precursors without changing any other process parameters whereas faceted NiNPs when using only anhydrous NiCl2 ...

In this study, silica nanoparticles (SiO2 NPs) were fabricated using a handmade ball mill as a novel, simple, rapid, costeffective, and green approach. The solgel method was also used to produce these NPs as a comparative method. The SiO2 NPs produced by both methods were characterized using highresolution transmission electron microscopy (HRTEM), dynamic light scattering (DLS), energy ...

The current production method of nanobiochar (NBC), an emerging, environmentally friendly nanocarbon material, is tedious and lengthy. Therefore, in this study we aimed to improve the productivity of NBC via highenergy ball milling by manipulating the grinding media and processing time. The particle size distribution of the resulting NBC measured using dynamic light scattering showed that ...

Here, we present all dry fabrication of superhydrophobic surfaces through mechanochemical grafting of silicone. The entire process consists of agitating silicone and nanoparticles in a planetary ball mill for a duration on the order of minutes. A lowcost and biocompatible silicone is employed for lowering the surface energy of nanoparticles.
