plasma electrolytic oxidation (peo) was performed on a 1010 aluminum alloy. to achieve thenanocomposite structure, si3n4 nanoparticles were added into the electrolyte. in an alkaline aqueoussuspension (silicate-based), the effect of adding niso4 on the applied voltage, microstructure,composition, wear, and corrosion resistance of peo coatings was investigated using scanningelectron microscopy (...

Hydrogen is a prospective energy carrier because there are practically no gaseous emissions of greenhouse gases in the atmosphere during its use as fuel. The great benefit hydrogen being inexhaustible carbon-free fuel makes it an attractive alternative to fossil fuels. I.e., circular process recovery and use. Another big advantage high content per unit mass compared Nowadays, broadly used trans...

Electrochemical reduction of CO2 into carbon-based products using excess clean electricity is a compelling method for producing sustainable fuels while lowering CO2 emissions. Previous electrolytic CO2 reduction studies all involve dioxygen production at the anode, yet this anodic reaction requires a large overpotential and yields a product bearing no economic value. We report here that the cat...

A remaining useful life prediction algorithm and degradation model for electrolytic capacitors is presented. Electrolytic capacitors are used in several applications ranging from power supplies on critical avionics equipment to power drivers for electro-mechanical actuators. These devices are known for their low reliability and given their criticality in electronics subsystems they are a good c...

A thin-film electrochemical sensor electrode capable of electrolytic conductivity, cyclic voltammetry, and temperature measurements of electrolyte solutions has been fabricated and characterized. The electrode fabrication and calibration is detailed, showing accuracies of 6 % for electrolytic conductivity measurements over the range of 0.1–100 mS cm 1 and temperature measurement within 2 C from...

In this paper, the necessity and key questions for detection of counterfeit components is being described. Main goal is to inform professionals from academic as well as from industry sector how to detect counterfeit parts and be confident with evaluation. For these purposes some standard and some more specific methods are described more in detail. Electrolytic capacitors are very often used in ...
