and Studies of Titanium Dioxide Nanoparticles with Galactose Coating as a Prospective Drug Carrier.

In today's medicine, progress often depends on new products with special qualities. Nanotechnology focuses on the creation of materials tailored to fulfill specific therapeutic requirements. This study aims to elucidate the potential of nanoparticles, particularly titanium dioxide nanoparticles, as carriers for pharmaceutical agents.

Antimicrobial properties of WCO-based composites enriched with hops and curly sorrel for green building solutions.

Modern production of vegetable oils has reached impressive levels, and the ever-growing quantities of waste cooking oil (WCO) provide a local source of raw materials for innovative materials. The WCO composite production process involves a series of reactions, including polymerisation, esterification, and transesterification, which lead to the hardening of composite materials. In light of the growing problem of bacterial and fungal diseases, materials with high strength properties and biocidal properties are being sought.

Bio-enriched composite materials derived from waste cooking oil for selective reduction of odour intensity.

Currently, pathogenic microorganisms are becoming more active in public utility areas like parking lots and waste shelters due to the accumulation of organic waste. This uncontrolled waste leads to decay, altering its composition and presenting a microbiological risk to public health. Additionally, it emits unpleasant odors containing chemicals that irritate the mucous membranes, causing discomfort in the nose, throat, and eyes by stimulating the trigeminal nerve.

Effect of Waste Cooking Oil-Based Composite Materials on Radish Growth and Biochemical Responses.

Waste cooking oil poses a serious threat to human health and the environment, both in households and in larger communities. One of the applications of waste cooking oil is composite materials called vegeblocks, which can be used for construction purposes. These composites are formed by the process of polymerisation, esterification and polyesterification.

Assessment of the Environmental Impact of Solid Oil Materials Based on Pyrolysis Oil.

One method of managing used car tires is decomposition by thermochemical conversion methods. By conducting the process at temperatures of 450-750 °C, three fractions are obtained from tires: oil, gas, and solid. The liquid product of the pyrolysis of used car tires is pyrolysis oil, which consists of aromatic, polyaromatic, and aliphatic hydrocarbons.

Synergistic effect of sorption and photocatalysis on the degree of dye removal in single and multicomponent systems on ZnO-SnO.

The paper presents the photodegradation process of one-, two- and three-component dye mixtures by ZnO-SnO nanoparticles. After 60 min of running the processes, the dye removal efficiencies of 76.44, 72.

Antimicrobial properties of nanoparticles in the context of advantages and potential risks of their use.

The popularity of nanotechnology results from the possibility of obtaining materials that have better chemical, electrical, thermal, mechanical, or optical properties. Nano-sized materials are characterized by an increased surface area, which improves their chemical reactivity and mobility. Due to their enhanced reactivity and appropriately small size, some nanoparticles are used as antimicrobial and antifungal agents.

Preparation and of PVA-based compositions with embedded silver, copper and zinc oxide nanoparticles and assessment of their antibacterial properties.

A series of poly(vinyl alcohol) (PVA) based liquid compositions with addition of zinc oxide, silver and copper nanoparticles has been prepared. The compositions also contained other consistency-forming organic components. The physico-chemical properties of the products have been determined.

Obtaining of oil blocks as a way to manage hazardous asbestos.

In the second half of the 20th century, asbestos extraction was up to 4 Mt/year. Due to its high strength and insulation properties, this mineral was used as an additive in building materials. Over time these materials were destroyed by the process of weathering and leaching.

Analysis of the Exposure of Organisms to the Action of Nanomaterials.

The rapid development of the production of materials containing metal nanoparticles and metal oxides is a potential risk to the environment. The degree of exposure of organisms to nanoparticles increases from year to year, and its effects are not fully known. This is due to the fact that the range of nanoparticle interactions on cells, tissues and the environment requires careful analysis.

Methods for Reducing the Toxicity of Metal and Metal Oxide NPs as Biomedicine.

The rapid development of medicine has forced equally rapid progress in the field of pharmaceuticals. In connection with the expensive and time-consuming process of finding new drugs, great emphasis is put on the design and use of metal and metal oxides nanoparticles in nanomedicine. The main focus is on comprehensive presentation of both physicochemical properties and the possibilities of using, in particular, silver (Ag) and gold (Au) nanoparticles, as well as zinc oxide (ZnO) and titanium oxide (TiO) nanoparticles as drug carriers and in the treatment of cancer.

Studies on CWL with glycerol for combustion process.

Findings of more efficient energy recovery methods are focused on composite fuels consisting of coal, water, and waste materials. The use of such slurry fuels has enormous environmental benefits due to the potential for waste utilization and low emissions of harmful oxides to the atmosphere during the combustion process. In this study, we report the effect of waste glycerol on the rheological properties of coal-water fuel (CWS).

Residues from the thermal conversion of waste from the meat industry as a source of valuable macro- and micronutrients.

The increased consumption of meat (including poultry) observed over the last decade has led to the intensification of its production. With the production increase, the amount of generated waste also increases. Appropriate disposal of waste from the meat industry will significantly reduce the amount of such waste and its negative impact on the environment.
