Ball milling: The main principle of mechanical milling can be described as the exploitation of high energy grinding to reduce the particle size. In general, the high energy ball milling route is used to yield nanosized particles, especially for metallic PNPs synthesis [45]. To initiate the size reduction process, bulk samples of the NPs are ...

Milling was then performed in 80% ethanol for 30120 minutes using a highenergy ball mill. The mechanical treatment resulted in a reduction of the fibre length and diameter, probably due to degradation of the cellulose amorphous regions. Fibrillation was helped by the wet environment, which facilitated the intrafibre swelling.

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 ...

Ball milling. Ball milling is another technique which was reported very recently for the production of NFC. In this method, a cellulose suspension is placed in a hollow cylindrical container, partially filled with balls (, ceramic, zirconia, or metal). While the container rotates, cellulose is disintegrated by the high energy ...
