The polymerization of 1-vinyl-2-pyrrolidone (VP) mechanochemically initiated by grinding silica was investigated in a wet stirred media mill. The polymerization itself proceeds from the silica grinding without any additional initiator. We have found that the amount of grafted polymer increases with an increase in total ground silica surface.
Laser-assisted milling and grinding are an emerging manufacturing technology that combines the advantages of traditional machining techniques with the precision and control of laser technology. In this process, a laser beam is used to preheat the workpiece material, which softens and reduces its strength, making it easier to mill …
Under ball mill neat grinding conditions, the equilibrium is reproducibly represented by homodimers and Form A of the heterodimer in a molar ratio of 1 to 4. The heterodimer crystallizes in two different polymorphic forms, Form A and Form B, which can be interconverted by changing the milling conditions between neat grinding and liquid …
Mitochondria can be isolated rapidly from Neurospora crassa with high yields by disrupting the hyphae suspension between the two grinding wheels of a simple mill. The isolated mitochondria respire with pyruvate + malate, succinate, and with NADH and NADPH in high rates and well coupled to oxidative phosphorylation.

Three methods of pulverisation, each followed by the same extraction protocol, were compared. The first approach consisted of the lyophilisation of the sample in order to remove the excess of water before grinding, the second one used a cryogenic mill and the control one a mortar grinding of frozen tissue.

Disruption of the Hyphue by the Grind-Mill The suspended hyphae were disrupted by the grind-mill (Fig. 1). The lower grind wheel is rotated by an electric motor. The upper wheel is fixed at the bottom of the reservoir cylinder. An outlet neck at the bottom of the cylinder extends through the central hole of the upper wheel.

An experimental and numerical study on the grinding media dynamics inside a baffled ball mill under different solid-flow regimes, namely, cascading, cataracting, and centrifuging, is described. The Eulerian approach was used for all simulations and the boundary condition at the drum wall was investigated by means of the specularity coefficient ...

This problem can be addressed by maintaining the continuous low temperature within the mill thereby retaining most of the flavor strength per unit mass of spice. During development of low-temperature grinding mill, firstly design of cooling coil (evaporator) was done by considering the dimension of grinding chamber.
Introduction. Sunflower press cake (SPC) is the by-product of sunflower oil processing that is rich in protein (20–50 g 100 g −1), that contains a reasonable amount of dietary fibre and, after cold pressing, between 7 and 17 g 100 g −1 residual fat. Compared to soybeans, sunflower seeds are processed more regionally in central Europe so that …
The results of this study provided clear evidence that fine grinding can ensure high MIR model performance (0.6 < R 2 < 0.92, see Supplemental Table S1 for detailed statistics). However, the recommendation to apply fine grinding in sample processing for a project can be influenced by several factors.
