Hybrid Energy System - Optimization and New Concept
(Lublin University of Technology, 2014-09-16)Paper presents a research related to the design of a new concept of hybrid energy system. It describes actually used concepts and the benefits of new design. Subsequently, the problems of the proper systems setting and ... -
Electrochemical Behaviour of Nanoscale Ni Modified Screen-Printed Carbon Electrodes in Corrosion Tests and Hydrogen Evolution Electrocatalysis
(ESG, 2015-09-01)Corrosion resistence and electrocatalytic aktivity were examined for Ni nanoparticles ( NiNPs) coated screen printed carbon based electrodes ( SPCEs) being a novel alternative to unmodified electrodes. Corrosion as well ... -
The Influence of Solvents and Salts on the Properties of High-Voltage Cathode Materials
(ESG, 2015-07-24)Lithium - ion batteries play an increasingly important role in the battery industry and they have become the dominant source of energy in the recent years, especially for portable electronic devices due to their high ... -
Effect of Heat Treatment on the Corrosion and Mechanical Properties of Electrolytical Composite Ni-B Coatings
(ESG, 2014-08-01)Electrodeposition of composite coatings with nickel matrix and boron micro-particles was investigated. Nickel - boron layers were deposited potentiodynamically at 12.5 mV/s on cylindrical samples prepared from iron powder ... -
Effect of Compression on Negative Lead-Acid Battery Electrodes Doped with Glass Fibres
(ESG, 2015-11-04)Lead-acid battery with negative electrodes doped with microscopic glass fibres are comparable with those doped with carbon or titanium dioxide during accelerated PSoC cycling and reach a long cycle life. The performance ... -
Negative lead-acid battery electrodes doped with glass fibres
(ESG, 2015-03-01)Negative lead-acid battery electrodes doped with microscopic glass fibres show similar properties during accelerated partial state of charge cycling as those doped with carbon or titanium dioxide, including a long cycle ... -
Numerical simulation and experimental visualization of the separated cavitating boundary layer over NACA2412
(EDP Sciences, 2015-05-06)Cavitation is physical phenomenon of crucial impact on the operation range and service lifetime of the hydraulic machines (pumps, turbines, valves etc.). Experimental measurement of cavitation is expensive and time consuming ... -
Mathematical model of Mobile Circulatory Module for ex-vivo lungs perfusion
(IFAC, 2015-05-13)The article deals with mathematical modelling of a system for ex-vivo lung perfusion. The system which is modelled here is named Mobile Circulatory Module and is designed for transport of live lungs namely porcine or human ... -
Evaluation of different solutions of faulted phase earthing technique for an earth fault current limitation
(IET, 2017-06-12)The study is focused on evaluation of different types of prototypes of automatics for additional faulted phase earthing (FPE), which are used for earth fault (EF) current reduction in resonant earthed distribution network. ... -
Spatio-temporal description of the cavitating flow behavior around NACA 2412 hydrofoil
(IOP Publishing, 2015-12-06)Spatio-temporal description of the cavitating flow around hydrofoil with 8 degrees incidence using proper orthogonal decomposition (POD) is presented. POD is a suitable tool, which provides information not only about the ...
