1. Small lymphocytes in serum at 37 degrees C. migrate toward the anode under experimental conditions described. 2. The electromotive force of 0.8 volt per cm. under the same conditions produced a straight line velocity which approximated that reported by McCutcheon for spontaneous velocity after his preparation had been studied over 5 hours. 3. Keeping the lymphocytes on ice up to 30 hours did not produce an appreciable difference in velocity of straight line migration from that speed determined if the cells were studied immediately. 4. The possible relationships between the type and order of magnitude of the electromotive force passing between injured and normal tissues and the electromotive force used experimentally are briefly discussed.

Recently, ionic thermoelectric supercapacitors have gained attention because of their high open circuit voltages, even for ions that are redox inactive. As a source of open circuit voltage (electromotive force), an asymmetry in electric double layers developed by the adsorption of ions at the electrode surfaces kept at different temperatures has previously been proposed. As another source, the Eastman entropy of transfer, which is related to the Soret coefficient, has been considered.

The sensorless vector control method of synchronous reluctance motors (SynRMs), based on extended back electromotive force (EMF) or flux observation, has been widely applied in the medium- or high-speed range. However, in the low-speed and low-current range, the extended back-EMF and flux are nearly zero. The use of the current frequency () control method can enable the motor to pass through the low-speed region, thereby ensuring that the back-EMF and flux reach a large value.

Dissecting current rectification through asymmetric nanopores.

Rectification, the tendency of bidirectional ionic conductors to favor ion flow in a specific direction, is an intrinsic property of many ion channels and synthetic nanopores. Despite its frequent occurrence in ion channels and its phenomenological explanation using Eyring's rate theory, a quantitative relationship between the rectified current and the underlying ion-specific and voltage-dependent free energy profile has been lacking. In this study, we designed nanopores in which potassium and chloride current rectification can be manipulated by altering the electrostatic pore polarity.

Existing TAI systems mostly use metal wires to calibrate their spatial resolution. However, research on the imaging mechanism of the metal wire and the setting of the wire parameters that can affect the system's spatial resolution is not sufficient in this context. In general, there is a lack of understanding of the factors affecting spatial resolution.
