Verification of chlorine production through seawater electrolysis using ion-exchange membrane electrolytic bath

open access: yesZhongguo Jianchuan Yanjiu, 2021
ObjectiveTo prevent the marine biofouling adhesion and corrosion of ship hulls and pipes, a system is designed which produces chlorine through seawater electrolysis using an ion-exchange membrane electrolytic bath.

Efficiency droop in InGaN/GaN multiple quantum well light-emitting diodes with nonuniform current spreading [PDF]

open access: yes, 2011
We demonstrate that the efficiency droop phenomenon in multiple quantum well InGaN/GaN light-emitting diodes (LEDs) may be connected to the current crowding effect.

Coverage and efficiency in current SNP chips [PDF]

open access: yesEuropean Journal of Human Genetics, 2014
To answer the question as to which commercial high-density SNP chip covers most of the human genome given a fixed budget, we compared the performance of 12 chips of different sizes released by Affymetrix and Illumina for the European, Asian, and African populations.

Efficient Magnetization Reversal with Noisy Currents

open access: yesPhysical Review Letters, 2006
We propose to accelerate reversal of the ferromagnetic order parameter in spin valves by electronic noise. By solving the stochastic equations of motion we show that the current-induced magnetization switching time is drastically reduced by a modest level of externally generated current (voltage) noise.

Brownian rectifiers in the presence of temporally asymmetric unbiased forces [PDF]

open access: yes, 2004
The efficiency of energy transduction in a temporally asymmetric rocked ratchet is studied. Time asymmetry favours current in one direction and suppresses it in the opposite direction due to which large efficiency ~ 50% is readily obtained.

Current-Drive Efficiency in a Degenerate Plasma [PDF]

open access: yesPhysical Review Letters, 2005
In a degenerate plasma, the rates of electron processes are much smaller than the classical model would predict, affecting the efficiencies of current generation by external noninductive means, such as by electromagnetic radiation or intense ion beams.

The Microstructure Properties of Ni-W Alloy Electrodeposition

open access: yesمجلة النهرين للعلوم الهندسية, 2018
The Electrodeposition process has been used to prepare Nickel-Tungsten alloys on low carbon steel substrate by using ammonical citrate bath. The influence of deposition condition by variation of current density (0.04-0.2 A/cm2) and solution temperature ...

A Study of Precision Current Efficiency Curve Measurement with a Casing-Type Anode

open access: yesApplied Sciences, 2021
Electrochemical machining (ECM) is a non-traditional machining technology that is widely used in the manufacturing of key components in the aviation industry. The current efficiency is defined as the ratio of the observed amount of dissolved metal to the

Comparison between unipolar and bipolar single phase grid-connected inverters for PV applications [PDF]

open access: yes, 2007
An inverter is essential for the interfacing of photovoltaic panels with the AC network. There are many possible inverter topologies and inverter switching schemes and each one will have its own relative advantages and disadvantages.
