Background and objective: The conventional chemical and physical methods for water disinfection include the application of ultraviolet (UV), chlorination, and ozonation. Water disinfection by electrochemical methods has been increasingly carried out recently. The goal of this applied - analytical research is to investigate the removal of E. coli bacteria, as the index of water microbial contami...

Pre-electrolysis at the boiling point in open Pd|D2O cells is an effective method to activate a palladium cathode, which can produce excess power in subsequent electrolysis in closed systems for several months. The reproducibility is 23/45. Another characteristic of excess heat is the apparent resistance of electrolytic cell changes irreversibly with temperature.

A facile unipolar pulse electrodeposition combined with the thermal oxidation method was applied for fabrication of CuO/Co3O4 composites on carbon electrode for water electrolysis, and it was found that the sea anemone-like one with a 3D hierarchical structure formed at -0.8 V exhibited excellent performance for water electrolysis at a low overpotential with high stability.

Surface studies of 40 μm thick Pd foils after electrolysis in D 2 O / H 2 SO 4 electrolyte for six minutes found inversions in isotopic ratios. Anomalous isotopic ratios were also found on the surface of a 350 μm thick Pd foil after electrolysis in the same electrolyte for 74 hours.

This review makes the case for cheaper and more efficient water electrolysis technology. In particular, the potential advantages of zero gap, alkaline water electrolysers based on hydroxide ion conducting membranes are highlighted. Following a brief introduction into the thermodynamics and kinetics of water electrolysis, recent developments in oxygen evolving anodes, hydrogen evolving cathodes ...

Samples of palladium sheet supplied by IMRA Japan were tested for anomalous energy production using electrolysis in heavy water and a sensitive calorimeter. Several samples were found to produce significant power above that being applied to produce electrolysis. This behavior was found to correlate with certain properties of the palladium metal. In addition, the anomalous heat was shown to orig...

The aim of this work is to study the degradation and mineralization of antibiotic ofloxacin in aqueous medium using the Electro-Fenton method as advanced oxidation technology. In this context, Pt/carbon-felt cell was used to investigate the influence of various parameters including initial pH, different supporting electrolytes, different metal ions as a catalyst and antibiotic concentration ove...

Presented here are results of research performed at Portland State University during the period 1994 to 1996. Excess heat was produced at the rate of about 1.2 watts during electrolysis of heavy water with a titanium cathode weighing 0.0625g. Analysis of the electrodes before and after electrolysis with a scanning electron microscopy (SEM) and an energy dispersive spectrometer (EDS) revealed th...

The molten carbonate fuel cell (MCFC) has evolved to current megawatt-scale commercial power plants. When using the fuel cell for electrolysis (MCEC), it provides a promising option for producing fuel gases such as hydrogen, via water electrolysis, and syngas, via co-electrolysis of water and carbon dioxide. The molten carbonate cell can thereby operate reversibly as a dual energy converter for...
