In comparison, the ball-mill reaction afforded 66% of the product (Table 4, entries 5–7). The Michael addition of aldehyde 6c gave under dry stirring products 8e and 8f in 76 and 79% yield with comparable diastereoselectivity and enantioselectivity (Table 4, entries 8 and 9).

After milling, the ball‐mill container was opened inside argon‐filled glove box, and nanosilicon was collected and stored inside glove box under argon atmosphere. This nanosilicon sample is referred as PV nano‐Si. To produce PV nano‐Si/graphite hybrid, the same planetary ball mill (PULVERISETTE P5 5/4 classic line) was used.

South America-focused Equus Mining has raised $3.3 million in a placement managed by Taylor Collison. The raising was priced at 17c, a 6% discount. Equus recently completed the acquisition of the Cerro Bayo project. Great Northern Minerals has received commitments to raise $3 million at 0.6c per share, a 23% discount to the 15-day VWAP.
The transfer from mill pass to pass was done by hand tongs and walking around the mill with the object or passing it over the mill for additional passes. Two similar in-line mills for alternate passes or three-high mills with alternate passes in lower and higher slots decreased the time so that no reheating was necessary (McQueen, 2009; McQueen ...

By ball milling graphite with Cl 2, Br 2, and I 2, a series of edge-selectively halogenated GnPs (XGnPs, X = Cl, Br, I) have been prepared . Although the electron negativities of halogen atoms are in the order of Cl (x = 3.16) > Br (x = 2.96) > I (x = 2.66), the experimentally observed electrocatalytic activities for ORR are in the order of ...

The ball mill is a device consisting of a revolving steel cylinder in which iron or steel balls do the crushing. The pulverized charcoal and sulfur are then stirred into a saturated solution of saltpeter at a temperature of about 130 C (265 F) . The mass is then spread on a floor to cool, after which e0 it is ready for incorporation . The lumps ...

The EJ201 and EJ202 engines had an aluminium alloy cylinder head with cross-flow cooling. Unlike the EJ20 engine, the intake ports for the EJ201 and EJ202 engines created a 'tumble swirl' motion for air as it entered the cylinder for better mixing of the air and fuel for more uniform flame travel and faster combustion.
Grinding Studies. Two kinds of mills, BBM and LBM, were used to achieve the desired P 80 passing percentage of 150 μm with an acceptable range of hematite liberation (> 75%) at optimum grinding time. The BBM is a standard ball mill having a length and diameter of 300 mm × 300 mm with smooth liner as shown in Fig. 2.A rotating drum is attached to a …
