To ensure safe drinking water and reduce the harmful impact of wastewater on the environment, pollutants are removed using various water treatment procedures such as oxidation, adsorption, filtration, and biological processes. However, conventional methods only partially remove pesticides, pharmaceuticals, and other organic micropollutants from wat...

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 ...

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 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...

Water electrolysis, powered by sustainable energy sources, represents a key technology for a green hydrogen production, offering a clean and renewable energy solution. However, the efficiency of this process is primarily constrained by the sluggish kinetics of the oxygen evolution reaction (OER), which significantly increases the overall energy dem...

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 ...

Edible oils undergo undesirable changes over time or during thermal treatment due to enzymatic, microbial, and chemical processes, leading to spoilage. In this study, the oxidative state of sunflower oil was assessed by determining the peroxide value (PV), anisidine value (AV), and Totox value (TV) using standard methods. The oil was heated at temp...

Due to intensive food production, the generation of agricultural waste leads to a significant environmental impact. Nuts, such as hazelnuts, walnuts, and pistachios, are produced in millions of tons annually, given their proven health benefits in human nutrition. However, their consumption implies separation of edible part from the shell, which rem...
