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...

Abstract This study presents an investigation on the specific electrical conductivity of cathode materials used in aluminium electrolysis cell over a temperature range between room and 950 °C. Those are subjected to diffusion related aging process due high operating cell, leading change chemical composition microstructure. The were investigated both initial state before use after period 5 years...

The development of high efficient and low energy consumption approaches for the transformation of cellulose is of high significance for a sustainable production of high value-added feedstocks. Herein, electrocatalytic oxidation technique was employed for the selective conversion of cellulose to gluconate in alkaline medium by using concentrated HNO3 pretreated carbon aerogel (CA) supported Au n...

Molten salt electrolysis is a proven technology for the extraction of metals -all the world's primary aluminum is produced in this manner. The unique properties of molten salts also make them excellent media in which to treat a variety of forms of waste. Of special note in this regard is electrolysis in molten oxides, a concept put forward by the author, initially as a "clean technology" for pr...

We performed a ultra—short width high voltage pulse electrolysis using a thin Pd wire cathode; a diluted electrolytic solution of D2O+LiOD was used in a peculiar wire—turned electrodes geometry. The deuterated Pd loading was evaluated by the D/Pd normalised electric resistance curve (R/Ro). After a long time of electrolysis a very high D/Pd loading (1:1 or more) was reached. Very low R/Ro (< 0....

A composite cathode based on redox-stable La0.2Sr0.8TiO(3+δ) (LSTO) can perform direct carbon dioxide electrolysis; however, the insufficient electro-catalytic activity limits the electrode performances and current efficiencies. In this work, catalytically active scandium is doped into LSTO to enhance the electro-catalytic activity for CO2 electrolysis. The structures, electronic conductivities...

This paper presents a neural network model based on the cell resistance signal. In the model, the anode current spectral energy is set as the input vector; the normal production, anode anomaly and metal wave are set as the output sample. By using genetic algorithm to optimize the initial weights and thresholds of the network, the model realized the diagnosis of the anode anomaly and metal wave ...

On electrolysis of NAD+ in aqueous solution at a potential corresponding to the initial one-electron reduction of NAD+ to a free radical, a greenish-yellow color appears which fades when electrolysis is complete. Literature ultraviolet absorption data for the resulting dimer show considerable variation. When the electrolysis is conducted in darkness, the colored product has epsilon 340 of appro...
