Conducting properties of mixed reverse micelles
Colloids and Surfaces A: Physicochemical and Engineering Aspects, 1999Abstract The conducting properties of mixed reverse micelles formed with AOT and other surfactants have been investigated, with the emphasis on the effect of solvents and surfactant composition. The phenomena observed were interpreted according to the formerly proposed physical meaning of W0,max, which stands for the molar ratio of water to ...

Power MOSFETs reverse conduction revisited
PESC '91 Record 22nd Annual IEEE Power Electronics Specialists Conference, 2002A contribution to the characterization of power MOS transistors under optimized switching behavior is presented. Reverse conduction through the channel resistance is imposed, avoiding the problem of integral diode recovery time without using external diodes. The control circuit design is discussed.

Study on the Reverse Conduction of Synchronous Rectifiers
TENCON 2006 - 2006 IEEE Region 10 Conference, 2006A study on the reverse current phenomenon in synchronous rectifiers is presented in this paper. For loss reduction, the synchronous rectifiers composed of MOSFETs have recently been employed to replace the conventional rectifiers with diodes in low voltage and high current applications.

Reversing the Conductance Evolution of Azobenzene Derivatives in Photoisomerization
Physical Review LettersPhotoisomeric azobenzene derivatives with distinguished conductance in trans and cis states have gained extensive attention for their potential application in fabricating light-controlled electronic switches, which, however, faces great challenges due to the quenching effect once they are coupled to the electrode.

Current Reversal and Negative Conductance for a Super-Conducting Junctions Device
Communications in Theoretical Physics, 2009In the paper, we study a super-conducting junctions device subject to an input periodic signal and a constant force. It is shown that, for this device, we can get current reversals for the current of the electron pairs versus the frequency of the periodic signal and negative conductance for the current of the electron pairs as a function of the ...

Reversible, Nanometer-Scale Conductance Transitions in an Organic Complex
Physical Review Letters, 2000Reversible conductance transitions are demonstrated on the molecular scale in a complex of 3-nitrobenzal malononitrile and 1, 4-phenylenediamine, by application of local electric field pulses. Both macroscopic and local current-voltage (I/V) measurements show similar electrical bistability behavior.

Reversible Block of Nerve Conduction by Ultrasound
Archives of Neurology, 1961Introduction In recent years ultrasound has found a number of important applications to biological problems. In particular, its destructive effects on the nervous system promise to be of experimental as well as practical value. 1-4 In appropriate dosage it may enhance or depress the functional activity of the central nervous system.

Acetazolamide reversibly inhibits water conduction by aquaporin-4
Journal of Structural Biology, 2009Aquaporin-4 (AQP4) has been implicated in cytotoxic brain edema resulting from water intoxication, brain ischemia or meningitis. AQP4 inhibitors suitable for clinical use would thus be expected to help protect against brain edema. Here, we report the effect of inhibitors on water conduction by AQP4 and AQP1 reconstituted into liposomes.

Reversible Conductance Switching of Single Diarylethenes on a Gold Surface
Advanced Materials, 2006Light-controlled conductance switching of diarylethenes attached to Au(111) is reported (see figure). First, scanning tunneling microscopy is used to demonstrate reversible photoswitching for individual molecules. Second, reversible switching in self-assembled monolayers is established by means of optical spectroscopy.
