A process for charging a discharged electrochemical cell includes applying a voltage bias to the discharged electrochemical cell; and illuminating the cathode with a light source.

Photo-assisted fast charging of lithium manganese oxide spinel (LiMnO) in lithium-ion batteries

An intramuscular stimulation needling device for chronic pain relief. The needling device can include a stepper motor, a needle, and a control unit. The needle can poke an affected muscle tissue and driven by a stepper motor in reciprocating manner. In each cycle, the needle moves a pre-determined distance forwardly in a first half cycle and retracts to original position in a second half cycle. The control unit can accelerate of the needle one or more times in the first half cycle at spaced intervals and decrease the velocity in the reverse pattern in the second half cycle.

Photo-assisted fast charging of lithium manganese oxide spinel (LiMn2O4) in lithium-ion batteries

An electrochemical cell includes a cathode, an anode, a non-aqueous electrolyte, and a cathode illumination source.

A porous membrane provides enhanced filtration of pollutants and particles by coating the membrane with conformal thin films of doped titanium dioxide via atomic layer deposition or, alternatively, sequential infiltration synthesis. The membrane can either be organic or inorganic, and the doping of the membrane, usually with nitrogen, is an important feature that shifts the optical absorption of the TiOfrom the UV range into the visible-light range. This enables the use of lower energy light, including sunlight, to activate the photocatalytic function of the film. The coating described in the present invention is compatible with virtually any porous membrane and allows for precise tuning of the pore size with molecular precision. The present invention presents a new coating process and chemical structure that provides catalytic activity, strongly enhanced by light, to both mitigate fouling and break down various organic pollutants in the process stream.
