Copper – Zinc and Copper-Iron Binary Electrode for Hydrogen Evolution Reaction
(SAKARYA ÜNİV., 2018)
The different coatings with high hydrogen evolution reaction (HER) durability activity were prepared by
electrodeposition. Iron, copper and zinc alloys were deposited on graphite electrode. The binary coating
prepared ...
Prediction Of Surface Hardness in a Burnishing Process Using Taguchi Methot, Fuzzy Logic Model and Regression Analysis
(Yıldız Technical Univ, Yıldız Campus, Besiktas, Istanbul, 34349, TURKEY, 2018)
The available work is aimed for comparison and estimation of surface hardness in ball burnishing process of aluminum alloy based upon the Taguchi technique, Fuzzy logic and regression models. The ball burnishing parameters ...
Numerical investigation of flow and heat transfer in communicating converging and diverging channels
(Yildiz Technical University, 2018)
Fluid flow and heat transfer in communicating converging and diverging channel has been numerically investigated. Channels are assumed to be at constant wall temperature and the flow is assumed to be steady state and ...
Power optimization in partially shaded ohotovoltaic systems
(UNIV NORTH., 2018)
The Power-Voltage characteristic of a photovoltaic (PV) array exhibits non-linear behaviour when exposed to uniform solar irradiance. Maximum Power Point (MPP) tracking is challenging due to the varying climatic conditions ...
A review study on energy harvesting systems for vechiles
(UNIV NORTH., 2018)
The widespread and increasing consumption of fossil-based fuels as an energy source causes a rapid decrease of these natural sources, as well as an increase of pollution in the atmosphere. Fuel oil, one of the products of ...
Forced vibration analysis of inhomogeneous rods with non-uniform cross-section
(Academic Publication Council, 2018)
Forced vibration analysis of cantilever rods is presented that have material properties and cross-section areas that arbitrarily vary in the axial direction, solved using Laplace transform in time domain and complementary ...
Energy and exergy analysis of an organic Rankine-Brayton combined cycle
(GAZI UNIV, 2018)
In this study, thermodynamic analysis of reheat and intercooled Brayton cycle combined with organic Rankine cycle (ORC) using waste heat from intercooler in Brayton cycle as heat source is presented. The effects of different ...
Fe-Cu coated nickel mesh usage as cathode catalyst for hydrogen evolution reaction
(ELSEVİER, 2018)
Nickel mesh electrodes were used as the working electrode. Iron and copper were electrochemically
deposited on the nickel mesh in different amounts. When electrochemical
coatings had been carried out, different currents ...
Rapid transformation of heterocyclic building blocks into nanoporous carbons for high-performance supercapacitors
(Royal Society of Chemistry, 2018)
The ever-increasing global energy consumption necessitates the development of efficient energy conversion and storage devices. Nitrogen-doped porous carbons as electrode materials for supercapacitors feature superior ...
Performance improvement potentials of low global warming potential refrigerants for intercity bus air conditioning system
(Serbian Society of Heat Transfer Engineers, 2018)
In this study, theoretical investigation of two evaporator ejector refrigeration system was carried out based on energy and exergy analysis using R134a and low global warming potential refrigerants (namely R1234yf and ...
