Vaccinium myrtillus fruits and leaves show significant economic importance due to their application in food, functional food, pharmaceutical, cosmetic, and healthcare products. Bilberry leaves contain valuable components, such as phenolic acids, flavonoids, procyanidins, anthocyanins, fatty acids, and dietary fibers. The mentioned compounds possess...

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...

Amaranth belogs to the group of pseudocereals. This pseudocereal is rich in proteins and does not contain gluten. Therefore, it is suitable for people on a gluten-free diet. In recent years, the number of people suffering from celiac disease or who are allergic to gluten has been increasing every day. The aim of this paper was to examine how the pa...

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, ...

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...

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...

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 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...

The Plavica deposit is located in the northwestern part of the Zletovo ore field, which belongs to the central part of the Kratovo-Zletovo volcanic area in the Republic of North Macedonia. Two mineralogical-geochemical ore zones have been formed in the deposit: upper one - oxide (secondary) with an Au content of 0.8 to 2 gr/t and lower one - sulfid...
