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...

Nuclear energy can be used as the primary energy source in centralized hydrogen production through high-temperature thermochemical processes, water electrolysis, or high-temperature steam electrolysis. Energy efficiency is important in providing hydrogen economically and in a climate friendly manner. High operating temperatures are needed for more efficient thermochemical and electrochemical hy...

In recent years, substantial improvements reactor design have significantly improved the economic viability this technology; thus, field has experienced rapid increase research interest. Among factors related to design, ion exchan...

The separator is a critical component for the performance of alkaline water electrolysis as it ensures ionic contact between electrodes and prevents product gases from mixing. While conductivity affects cell voltage, permeability dissolved influences gas impurity. Currently, diaphragms are used separators, pore system which filled with electrolyte solution to enable exchange ions. breakthrough ...

BACKGROUND/AIMS Three methods of electrical energy-based depilation were compared for safety and efficacy. METHODS Ten volunteers had one treatment with each device followed by weekly observations up to 9 weeks. The protocol used was basically that of the International Guild of Professional Electrologists, which is used to define "permanent" hair removal. RESULTS Radio frequency tweezers, d...

Hydrogen loading of 99.98% pure natural uranium foils (0.18 mm thick) was performed by aqueous electrolysis in order to compare with glow discharge results. Alpha, beta, and gamma specific radioactivity were measured after hydrogen loading and compared with the control. Some of the samples revealed an increase of the specific radioactivity of up to 20%. Gamma ray spectroscopy was also performed...

The use of electrochemically active bacteria to break down organic matter, combined with the addition of a small voltage (> 0.2 V in practice) in specially designed microbial electrolysis cells (MECs), can result in a high yield of hydrogen gas. While microbial electrolysis was invented only a few years ago, rapid developments have led to hydrogen yields approaching 100%, energy yields based on...
