Electronic Double-Layer Capacitors (EDLC), called Supercapacitors (SC), are electronic devices that are capable to store a relatively high amount of energy in a small volume comparing to other types of capacitors. They are composed of an activated ca

Degradation of Supercapacitors (SC) is quantified by accelerated ageing tests. Energy cycling tests and calendar life tests are used since they address the real operating modes. The periodic characterization is used to analyse evolution of the SC par

Nitrogen dioxide represents threat to human health even at low concentrations. A new amperometric sensor with three-electrode topology (platinum/solid polymer electrolytes/carbon) was developed to overcome limitations of standard solid NO 2 sensors b

A new method for the determination of parameters for an equivalent electrical circuit model of supercapacitors is proposed. The method is based on the evaluation of the time dependence of voltage measured on the supercapacitor terminals after its cha

2017 30th International Vacuum Nanoelectronics Conference (IVNC).
The paper describes electrical noise of experimental field emission cathodes based on “polymer” pencil leads which have a high content of hybridized carbon with a low degree of surface oxidation and silicon monoxide (SiO). Charge transport within

2015 International Conference on Noise and Fluctuations (ICNF).
Noise diagnostics were performed on a tungsten hair-pin cathode operating in a vacuum (3 · 10−3 Pa). The cathode operates in thermal emission mode at several temperatures based on the level of heating. Several acceleration voltages have been used
