Nano-sized starch particles were prepared from potato starch via high-energy ball milling, which is a purely physical method. Scanning electron microscopy, transmission electron microscopy, Fourier transform infrared spectroscopy, differential scanning calorimetry, and viscometer were used to analyze the morphology and characteristics of the as-prepared nanoparticles.
Synthesis of nanomaterials by a simple, low cost and in high yield has been a great challenge since the very early development of nanoscience. Various bottom and top down approaches have been developed so far, for the commercial production of nanomaterials. Among all top down approaches, high energy ball milling, has been widely exploited for the synthesis of various
These results demonstrate that mechanical milling is a good preparation method for GNSs/Al composite and an optimal ball milling process need to be researched for the purpose of longer ball milling time (better dispersion) but little damage to graphene in the future.
milling and boron additions, will be combined to test the sintering properties and determine if they are improved upon even further compared to the individual processes. Multiple samples of pure alumina, 0.2 weight percent boron, and 1.0 weight percent boron are batched and processed in a ball mill for different time intervals. These
scale, and the large-scale preparation of nanoscale ener-getic materials involves great difficulties. Mechanical ball milling (also known as ball milling) is a desirable choice because it is suitable for massive and continuous prepar-ation of uniform morphology crystals that maintained the original crystal form.
