Synthesis and characterization of porous tungsten carbide with added tungsten silicides
(Elsevier Sci Ltd, Oxford, 2018)
Porous materials made of commercial tungsten carbide (WC) with the addition of thermally obtained tungsten silicides (WSi2 and W5Si3) were made. The main research's contribution is firstly finding optimal conditions for ...
Comparative analysis of mathematical models for supercritical extraction simulation from industrially valuable lamiaceae herbs
(Wiley, Hoboken, 2014)
The present study was aimed to compare different mathematical models used to simulate process of supercritical extraction from commercially important Lamiaceae herbs. Supercritical extractions with carbon dioxide from ...
Utilization of agro-industrial waste for removal of copper ions from aqueous solutions and mining-wastewater
(Elsevier Science Inc, New York, 2019)
In this study, unmodified lemon peel, as agro-industrial waste, was used to investigate removal efficiency of copper ions from aqueous solutions and mining wastewater. The effects of solution pH, adsorption time, metal ion ...
New surface characterization tools for alumina based refractory material exposed to cavitation - Image analysis and pattern recognition approach
(Elsevier Science Inc, New York, 2018)
The aim of this study was to examine the influence of cavitation erosion on the morphology of defects formed on the surfaces of alumina-based materials. The alumina-based samples were exposed to cavitation erosion for 42 ...
Modelling, simulation and optimisation of pulse-reverse regime of copper, silver and gold electrodeposition
(Carl Hanser Verlag, 2018)
Pulse-reverse power modes are used in galvanotechniques in order to obtain coatings with better characteristics in terms of gloss, adhesion, tracking sharp edges and uniform distribution of deposits on complex shape objects, ...
The Prediction of Heavy Metal Permeate Flux in Complexation-Microfiltration Process: Polynomial Neural Network Approach
(Springer International Publishing Ag, Cham, 2019)
Membrane filtration techniques are distinguished among methods for wastewater treatment and fully correspond to the requirements of the green concept of chemistry and production. The limiting factor for greater application ...
Comparison of cavitation erosion behavior of cordierite and zircon based samples using image and morphological analyses
(Elsevier Science Bv, Amsterdam, 2018)
In this study the resistance of cordierite and zircon to the cavitation erosion was investigated with the aim of possible spreading their application. Cavitation erosion test was applied using standard ultrasonic vibratory ...
