A mechanical ball milling method for ultrafast synthesis of a nickelbased metal organic framework (NiMOF) has been proposed. The NiMOF was successfully synthesized in merely one minute without any solvent, additives, or preliminary preparation. The effect of milling time, mechanofrequency, type of assistant liquid, and amount of assistant water were systematically explored.

One of the great challenges in the use of nanomaterials is their production at low costs and high yields. In this work aluminum nanoparticles, from aluminum powder, were produced by wet mechanical milling through a combination of different attrition milling conditions such as ballpowder ratio (BPR) and the amount of solvent used. It was observed that at 600 rpm with a BPR of 500/30 g for 12 h ...

Ball milling experiments were done in a high energy planetary ball mill at a rotating speed of 300 rpm. To avoid the occurrence of any undesirable polluted phases, the ballmilling experiments were halted periodically (every ks) and then restarted when the temperature of the vial reached about 300 K.

In this paper, a durable triboelectric nanogenerator inspired by a ball mill was designed by using metal balls in hollow drums as carriers for charge generation and transfer. Composite nanofibers were deposited onto the balls, increasing the triboelectrification with the interdigital electrodes in the inner surface of the drum for higher output ...

In the dry ball milling process [30,31], BN (1 g), sugar (5 g), and zirconia balls (60 g) were loaded into a 500 mL grinding jar. The zirconia balls were divided into three kinds with diameters of 10 mm, 5 mm, and 1 mm in a weight ratio of 2:5:3. The mixture was ball milled at 500 rpm for 24 h using a planetary ball mill (YXQM2L, MITR, China).
