Efficient charge stage

On charging with a current of 0.1 A/Ah, the gas evolution voltage is 2.35 to 2.40 V at 75% state of charge. This characteristic point marks the end of the efficient charge stage, and it can be checked by a voltage monitoring relay circuit. The duration of the... 

Performance The grinding-media diameter should preferably be 10 times that of the feed and should not exceed 100 times the feed diameter. To obtain improved efficiency when reducing size by several orders of magnitude, several stages should be used with different media diameters. As fine grinding proceeds, rheological factors alter the charge ratio, and power requirements may increase.

A number of experimental in vivo gene therapy trials on animals using PAMAM dendrimers are in their preliminary stages. Numerous in vivo experiments are currently being conducted in order to optimize the dendrimer generation, concentration, and complex charge ratio to obtain optimal transfection efficiency.
