This study explores the hypothesis that Magnetic Resonance Imaging (MRI) can image the process of electrolysis by detecting pH fronts. The study has relevance to real time control of cell ablation with electrolysis. To investigate the hypothesis we compare the following MR imaging sequences: T1 weighted, T2 weighted and Proton Density (PD), with optical images acquired using pH-sensitive dyes e...

Electrochemical machining (ECM) has been increasingly recognized for the potential for machining, while the precision of the machined profile is a concern of its application. A process to erode a hole of hundreds of micrometers on the metal surface is analyzed in the current paper. A theoretical and computational model is presented to illustrate how the machined profile evolves as the time elap...

Perovskite oxides are attractive candidates as catalysts for the electrolysis of water in alkaline energy storage and conversion systems. However, the rational design of active catalysts has been hampered by the lack of understanding of the mechanism of water electrolysis on perovskite surfaces. Key parameters that have been overlooked include the role of oxygen vacancies, B-O bond covalency, a...

To be regarded as environmentally friendly and economical, an industrial process using 2,2,6,6-tetramethylpiperidine 1-oxyl (TEMPO) oxidation requires recycling and/or recovery of chemicals. In this work, hypochlorite recycling via electrolysis was evaluated and potential means for TEMPO recovery were explored. The most important variable affecting electrochemical hypochlorite conversion was th...

Recombination of electrolysis gases (oxidation of hydrogen and reduction of oxygen) is an important factor in operation efficiency of devices employing electrolysis such as actuators and also unitized regenerative fuel cells. Several methods of improving recombination speed and repeatability were developed for application to electrolysis microactuators with Nafion®-coated catalytic electrodes. ...

It is well known that electro-hydrodynamical effects in freely suspended liquid films can flow the liquid. Here we report a purely electrically driven rotation in water and some other liquid suspended films with full control on the velocity and the chirality of the rotating vortices. The device, which is called “film motor”, consists of a quasi two-dimensional electrolysis cell in an external i...

In carrying out the plasma electrolysis of water like experiments, lot of heat is emitted. This heat has a serious life hazards. A numerical studied has been carried out to investigate the Acute paronychia infection and other heat injuries, during plasma electrolysis of water experiments. The parametric dependence of the infection as a function of conductive, convective and radiative heat fluxe...

Electrolysis, a permanent hair-removal technique, involves the Molluscum contagiosum is a communicable viral disease that use of any of three different methods: galvanic electrolysis, theris confined to the skin. Molluscum contagiosum manifests itself molysis, or the blend method. In galvanic electrolysis, a needle as smooth-surfaced, firm, spherical papules with umbilication of (0.005–0.015 mm...

A sensitive open-type calorimeter was used to measure excess heat production during electrolysis in Li2SO4/H2O solution with Pt-anode and Pd-Ni thin film cathodes 9000 Å thick, sputtered on Al2O3 substrate. In order to estimate the actual performance and possible measurement errors during electrolysis in the calorimeter used, including heat convection, bubbling and possible H2+O2 recombination,...

The idea of hydrogen production by water electrolysis from renewable sources is one of the most obvious methods. It could not only lead to a significant reduction in greenhouse gas emissions, but also to increase the security of energy supply due to the method of clean storage. In this paper, we have borrowed a new method for hydrogen production by adapting the electrolysis to a photovoltaic (P...
