Heavy metals are natural components of the Earth's crust. They are highly persistent, so the total amount of their emissions from both natural and human technological activities accumulates in the soil and water. Due to their persistence, high toxicity, and tendency to accumulate in ecosystems, heavy metals pose a threat to living organisms. The ...

About 20% of the world's clean water pollution is considered to be caused by the textile industry's dyeing and finishing processes. Therefore, it is necessary to develop an environmentally acceptable but also economically profitable dyeing process. Wool is a natural fiber with a high content of keratin (about 80%) and sulfur and has specific proper...

The alumina nanoparticles (Al₂O₃) were synthesized using the sol-gel technique from an inorganic solution. The obtained nanoparticles had a microstructure of corundum after calcination at 1000°C. For characterization of alumina nanoparticles, use the FE-SEM/EDS method with mapping software, XRD, and TEM. The α-Al₂O₃ phase was detected wit...

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...

In this work, the inverse heat transfer analysis (IHTA) utilizing the Finite Element Method (FEM) has been used to detect the thermal properties of the soil where in situ soil temperature (ST) measurements together with that obtained theoretically are used in the solution. The initial values of the unknowns such as the soil thermal diffusivity are ...

Cancer is a serious risk to human life. Some predictions show a considerable increase in new cases and deaths by 2050. Chemotherapy and other conventional treatments encounter issues with a lack of specificity, leading to severe side effects on healthy tissues and drug resistance. Nanotechnology with targeted drug delivery shows improved diagnostic...
