Apr 09, 2021· The number of transferred electrons was similar in both 0.1 M HClO 4 and 0.1 M KOH, ranging from 3.3 to 3.7, again indicating that both catalysts allow the almost complete reduction of O 2 to H 2 O. From the results of the ORR study in 0.1 M KOH, we hypothesized that inherent impurities might overshadow the effect of aspect ratio and N-doping.

Mill (grinding) - Wikipedia

Ball mill. A typical type of fine grinder is the ball mill.A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.
