Testing the behavior of polymeric materials during heating, especially when it comes to materials that have wide practical application and therefore large commercial importance, such as polyurethanes, is essential. Results obtained by investigating thermal stability and thermal decomposition of polymers, including kinetic modeling, can help to unde...

Bauxite residue, commonly known as red mud is byproduct of the Bayer process for alumina production. It presents both environmental challenge as well as opportunity for resource recovery.  With high content of iron, titanium, and other valuable metals such as gallium, scandium and vanadium, red mud has gathered significant attention as a poten...

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...

Dyeing of polyester fabrics is usually done at high temperatures with the use of carriers and dispersants, which are often toxic. Standard dyeing methods not only consume large amounts of energy but also contribute significantly to environmental pollution. In this work, standard and alternative methods of dyeing polyester fabric with Disperse Red 6...

The Draft Tube Spout-Fluid Bed (DTSFB) is obtained by inserting a draft tube into a bed and introducing an auxiliary gas flow for aeration in the annular region. A specific modification of this system is a hydraulic barrier, which is an extension of the column from the bottom and whose diameter is smaller than the diameter of the column. The barrie...

Agricultural waste holds significant potential as a source of nutritionally valuable components but remains largely underutilized. Oilseed crop leaves, in particular, are rich in proteins, with the enzyme RuBisCO comprising a major portion of the protein fraction. However, RuBisCO extracted using standard methods often exhibits limited solubility, ...

Emulsifiers play a crucial role in modern cosmetic formulations, ensuring stability and enhancing the sensory properties of emulsions. Glyceryl Stearate Citrate (GSC) is a novel, naturally derived, biodegradable, and mild anionic emulsifier that has gained attention due to its excellent biocompatibility and multifunctionality. It is synthesized thr...

This study investigates the valorization of burnt IQOS cigarette waste into biochar and its subsequent activation to enhance structural porosity and surface area for environmental applications. Initiated by pyrolyzing the residual waste at high temperatures, the process yields a carbon-rich biochar, which is then subjected to a chemical activation ...

Cholesterol has garnered significant attention in research due to its role in both the structure and the fluidity/rigidity of phospholipid membranes. This property makes it an essential component in liposome formulation. Finding the right ratio of phospholipid-to-cholesterol is important for making a liposome formulation that is stable and works we...
