The World Health Organization (WHO) estimates that around 70–80% of the world’s population relies on non-conventional medications, most of which are derived from plant-based medicines. Dandelion (Taraxacum officinale) is a widely used medicinal plant in traditional medicine. In recent years, numerous studies have been conducted to impro...

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...

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 primary aim of this study is to develop a membrane from treated waste hemp fibers using a dimethyl sulfoxide/tetra-n-butylammonium hydroxide (DMSO/TBAOH) solvent system and citric acid (CA) as an efficient adsorbent for the removal of cations and cationic dyes from water. The bio-renewable membrane (cHM) was prepared at the appropriate molar ra...

The extraction of gallic acid from the pomegranate peel was carried out in a column with a diameter of 40 mm, in which pomegranate peel grains with a diameter of 2 mm were placed in a packed bed. The extraction fluid is recirculated through the system using a centrifugal pump. The fluids used in the extraction are: water, ethanol:water=50:50 and et...
