The electronic transmission and conductance of Dirac electrons in an armchair graphene nanoribbon under external voltage are investigated with the transfer matrix method. We investigate velocity nanoribbons presence single multiple barriers show that coefficients can be modulated by varying order mode, number carbon atoms, barrier velocities. In particular, we find appears to fully transparent ...

When detecting the presence of partial discharge (PD) activity in insulation system high-voltage equipment, excitation voltages at variable frequency have been widely used instead power-frequency (50/60 Hz) sinusoidal voltage order to reduce charging power. This work reviews relevant research on PD very low (VLF) method, including or cosine-rectangular shape, and damped AC (DAC) method. Based h...

The linear sweep voltammetry potentiostatic approach was employed to electrochemically synthesize the conjugated copolymers P(3HT-random-HPDTP) at three distinct applied voltages (1.4, 1.435, 1.6 V). In relation their synthesis conditions, chemical structural, optical, and electrical properties were investigated compared using Fourier transform infrared (FTIR) spectroscopy, UV‒Vis absorption cy...

A non-thermal atmospheric pressure argon plasma jet for medical applications has been generated using a high-voltage pulse generator and a homemade dielectric barrier discharge (DBD) reactor with a cylindrical configuration. A plasma jet of about 6 cm of length has been created in argon gas at atmospheric pressure with an applied peak to peak voltage and a frequency of 10 kV and 50 kHz, respect...

Electroosmotic flow has been shown to be controlled via an applied radial voltage. Many factors determine the effectiveness of this control, and one major factor is buffer pH. In this study the effectiveness of the applied radial voltage for controlling electroosmotic flow while varying buffer pH is examined. Previously developed theory is applied and compared to experimental results for a pH r...
