As a class of bottomup viewpoint in nanoparticle synthesis, inert gas condensation is a perfectly developed and popular nanoparticle synthesis technique owing to its capability and flexibility to control the synthesis process. Briefly, the material is evaporated under the pure helium atmosphere with the helium atoms serving as a cooling agent condensing the atoms to finalize the formation of ...
Skyspring Nanomaterials, Inc. It is a ball milling process where a powder mixture placed in the ball mill is subjected to highenergy collision from the balls. This process was developed by Benjamin and his coworkers at the International Nickel Company in the late of 1960. It was found that this method, termed mechanical alloying, could ...

For dispersing nanoparticles in oil, the planetary ball mill method was used. The stability of fullerene nanoparticles in oil was reported to be acceptable, as after 720 h, there were no precipitation observed. It was also pointed out that fullerene resulted in the lowest thermal conductivity increase amongst all other carbon nanomaterials.
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.

Specifically, a planetary ball mill was used to grind silica nanoparticles and dodecyltrichlorosilane in a milling jar to obtain a superhydrophobic powder within 5 min. The use of ball milling in this application eliminates the need for solvent, which reduces waste and makes the process environmentalfriendly.
Given the increasing demand for multilayer ceramic capacitors (MLCCs) for miniaturization of electronic parts, a narrow nanoparticle size distribution is crucial to optimize MLCC performance and stability. We explored the sintering behavior of nickel powder with the goal of controlling particle size. A microsized nickel oxide powder was milled to uniform size ( ± nm) using a ...

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 ...
