Nov 11, 2014 The ball-mill was a Retsch MM 2000 swing mill with a 10 cm 3 stainless steel, double-walled beaker with fittings for circulating coolants. Two stainless steel balls of 12 mm diameter were used. Ball-milling was performed at 20,225 Hz frequency, usually at room temperature without circulating liquid and the temperature did not rise above 30 C.

Ball-milling utilizes mechanical stress to modify properties of carbon nanotubes CNTs including size, capping, and functionalization. Ball-milling, however, may introduce structural defects resulting in altered CNT-biomolecule interactions. Nanomaterial-biomolecule interactions result in the formation of the biocorona BC, which alters nanomaterial properties, function, and biological ...
Using a ball mill, rapid, atom-economic coupling between adenosine-5-phosphoromorpholidate and phosphorylated ribose derivatives as their sodium or barium salts was achieved. Facile purification by reversed-phase HPLC enabled product isolation within hours.
High-energy ball milling is usually used in three main applications 1 mechanical alloying, 2 reactive milling, and 3 particle deformation, the latter of which will be the focus of this paper. Zoz and Ren used yttria-stabilized ZrO2 balls to mill SiC powder with a starting particle size of 850 m.18 After 10 min of milling, the particle size
Aug 16, 2017 Following incubation in normal mouse serum, quantitative label-free mass spectrometry identified differences in the biomolecular content of the BC resulting from the ball-milling process. Further, incubation in cholesterol-rich mouse serum resulted in the formation of unique BCs compared to SWCNTs incubated in normal serum.
