The radiative models used in the numerical simulations of the pulverized coal-fired furnaces can be divided into flux and zonal models. For the zonal models, furnace volume and walls are divided into volume and surface zones. For the calculations of the heat exchange, the direct and total exchange areas for each pair of the zones are needed. The pr...

Modified carbon electrodes with TiO2 nanoparticles exhibit several advantages over other electrode materials. The electrochemical characteristics of the electrode material depend on various factors, including the type and size of carbon particles, the size of modifier particles, the choice of binder, the preparation method, and the surface morpholo...

The semi-rigorous model without holdups and the semi-rigorous model with minimum holdups give almost the same results. However, the former uses integration step 0.1 h and the latter integration step 0.00001 h. This, and the fact that a semi-rigorous model describes the dynamics of the batch distillation process more reliably than a shortcut model, ...

Laccases are essential enzymes in various industrial applications, playing a vital role in numerous industrial processes. When immobilized, laccases demonstrate enhanced resistance to environmental changes and offer the added benefit of being easily recoverable and recyclable, which makes them superior to their free forms. Immobilization primarily ...

Conductive polymer composites offer innovative solutions for real-time food quality monitoring by enabling direct interaction with spoilage indicators. In this study, polyaniline (PANI) doped with trifluoromethanesulfonic acid (TFMS) was synthesized via oxidative polymerization and incorporated into biopolymer matrices—polylactide (PLA) and p...

This work investigates the process of forming metallic coatings of nickel on copper using electrolytic deposition. By focusing on the optimization of deposition parameters, such as current density, electrolyte temperature and deposition time, high-quality coatings can be achieved in terms of corrosion resistance, strength, adhesion and aesthetic ap...

The consecutive microwave-assisted hydrothermal shelling combined with aerosol-assisted calcination was applied as a synthesis route for IrO2-shelled CoCeY oxide core composites, designed as potential high-efficiency catalysts for the oxygen evolution reaction (OER) with a reduced iridium content. The search for such efficient OER catalysts is of g...

The characteristics of nickel coatings obtained by electrochemical deposition on steel samples of known chemical composition were investigated. The chemical composition of the steel was examined using the XRF method (X-ray fluorescence spectrometry) before and after the deposition of the coatings. The effect of current density and deposition time o...

The inhibitory effect of Thyme (Thymus serpillum) extract (TSE) on the corrosion of two steel types in 4% HCl solutions was investigated (Steel 1 - DC01 and Steel 2 - X5 CrNi 18-10). Steel samples were chemically prepared followed by the examination of corrosion rate in both uninhibited and inhibited HCl solutions. Four solutions were used: Solutio...

In this paper, the influence of steel type, inhibitor concentration, and time on the inhibitory effect of dandelion root extract in a 4% HCl solution was investigated. Two types of steel of known composition were used, and the inhibitory effect was monitored in a time interval of 2, 4, 6, 24 and 48 hours. Dandelion root extract was obtained by the ...
