The aim of this research is to present a simple online condition monitoring system to predict failure of the aluminum electrolytic capacitors used in the output LC filter of the switched mode DC–DC buck converters. Equivalent Series Resistance (ESR) is the best indicator of the failure of the aluminium electrolytic capacitors. The main idea of the proposed method is to monitor the ESR value and...

I N THE previous paper a technique for the determination of the electrolytic resistance of the blood clot was presented (I). The present paper deals with the variations in the electrolytic resistance of the blood clot over a 40. to &-hour period, and with the physiological significance of certain measurements of the resistance. The curve of the resistance against time will be called the electro...

appeared a report on Electrolytic Chlorogen by Captain W. Hodgkinson, r.e., and Mr. C. M. Hutchinson, c.i.ii., Imperial Agricultural Bacteriologist of the Agricultural Research Institute, Pusa. The principal objects of this enquiry, which were carried out under the auspices of the Army Department (Simla), were to determine the possibility of preparing in India from indigenous materials and by s...

We have developed a novel electrolytic cell pressurized by D2 in which deuterium loading ratio in a palladium cathode can be determined in-situ during the calorimetric measurements of excess heat. A gas diffusion type fuel cell anode is partially immersed in the electrolyte solution to act as a counter electrode, at which electrochemical oxidation of deuterium gas molecules to deuterium ions ta...

In this theoretical investigation, a hybrid power generation system utilizing wind energy and hydrogen storage is presented. Firstly, the available wind energy is determined, which is followed by evaluating the e$ciency of the wind energy conversion system. A revised model of windmill is proposed from which wind power density and electric power output are determined. When the load demand is les...

Hydrogen permeation reduces a material’s properties and increases the risk of brittle fracture, which causes potential safety hazard. A workpiece’s hydrogen resistance could be improved by improving its surface integrity through processing. This paper studies low-alloy steel’s in production reactor, using electrochemical cathodic hydrogen-charging method to carry out experiments. After specimen...

Water-fed photo-electrolysis cells equipped with perfluorosulfonic acid (Nafion® 115) and quaternary ammonium-based (Fumatech® FAA3) ion exchange membranes as separator for hydrogen and oxygen evolution reactions were investigated. Protonic or anionic ionomer dispersions were deposited on the electrodes to extend the interface with the electrolyte. The photo-anode consisted of a large band-gap ...

Metallic aluminum is widely used in propellants, energy-containing materials, and batteries due to its high energy density. In addition burning the air, can react with water generate hydrogen. Aluminum carbon-free solid-phase products be recycled easily after reaction. Micron powder stable air enables global trade. metal considered a viable recyclable carrier for clean energy. Based on reaction...
