AB  - Polymethyl methacrylate (PMMA) is a polymer material widely used in dental applications due to its excellent biocompatibility, stable physicochemical properties, easy manipulation, and low cost. The combination of biocompatible polymers and ceramics has great potential for the development of materials in the dental industry with improved mechanical properties. The addition of Al2O3 nanoparticles to PMMA can significantly improve its compressive and flexural strengths and wear resistance. Since this material is used in dental applications, it requires a high degree of product sterility. This can easily be achieved with gamma radiation treatment. Gamma radiation not only ensures the sterility of the product but can also affects changes in numerous material properties. The aim of this paper is to determine the influence of different doses of gamma radiation on the microbiological purity and changes in the mechanical and thermal properties of the PMMA/Al2O3 composite as well as the microstructural and color changes. It was found that the dose of radiation of 25 kGy is sufficient for complete sterilization of the product. This radiation dose improves the mechanical properties of the material and thermal stability. On the other hand, the dose of 25 kGy does not affect the morphology of the exposed sample and has small effect on the color change.

AB  - The removal of environmental pollutants is significant because of their harmful effects on living organisms. Biochar is favorable as a natural adsorbent of environmental pollutants due to its advantages, such as environmental acceptability and economic profitability. This study evaluated the potential of pyrolyzed plum pomace (PyrPP) as an adsorbent for environmental pollutants: Pb2+ ions, pesticides (chlorpyrifos and malathion), as well as organic pollutants BTEX. In order to ameliorate the adsorption capacity of PyrPP, modification by gamma irradiation was performed. Irradiated plum pomace biochar (IrPyrPP) has been shown to be an effective adsorbent, and the material is also sterilized by irradiation, which makes this material potentially sterile adsorbents of the most environmental pollutants from water. The irradiated biochar showed better adsorption performances for the removal of Pb2+ ions, BTEX, and chlorpyrifos. Maximum adsorption capacity (Qmax) of PyrPP for Pb2+, BTEX, chlorpyrifos, and malathion adsorption was 157.0, 17.6, 0.219, and 1.067 mg g− 1 , while Qmax of IrPyrPP for Pb2+, BTEX, chlorpyrifos and malathion was 271.0, 48.0, 0.428 and 0.593 mg g− 1 , respectively. The results obtained during this research suggest that biomass pyrolysis and modification of this biomass by irradiation is a promising way to produce efficient natural sterile sorbents for wastewater treatment.

AB  - Polymeric materials are widely used in the chemical and optical industries, the packaging materials industry, and biomedicine. New technologies and the search for innovative and sustainable solutions have contributed to the development of polymer sensors and smart materials. Poly(vinyl-alcohol) (PVA) is a thermoplastic polymer soluble in water. It belongs to the group of non-toxic and completely biodegradable polymers, with excellent thermal and mechanical properties. Polymer-colored films have great potential as sensor systems, primarily due to their visual color change, which makes them easy to use. Azo dyes, which are used for coloring polymer films, represent the most important class of synthetic dyes, and their exceptional properties are reflected in high extinction coefficients, as well as excellent fastness to light and wet processing. Traditionally, azo dyes are used in the food and cosmetic industries, and are also used as pH indicators.
In this work, in addition to the synthesis of azo pyridone dyes, polymeric films were also synthesized. The first series of films were synthesized based on PVA and newly synthesized azo dyes, and the sensory properties of the new films were tested. The second series of films were synthesized in order to test the films as dosimeters for γ-radiation, and for this reason, TTC was added to their synthesis. The dye used in the experiments were characterized by ATR-FTIR, NMR and UV-Vis spectra. The chemical structure of the synthesized films was analyzed by ATR-FTIR spectroscopy. The sensory properties of the film were tested in solutions of different pH values, while the possibility for application in dosimetry was tested at different doses of γ-radiation at the 60Co source. Changes in the color of the films were monitored spectrophotometrically by recording reflection spectra.

AB  - The heterocyclic azo dyes represent significant synthetic organic colorants. In addition to their exceptional coloration properties, heterocyclic azo compounds exhibit antibacterial, antifungal, an-tiviral, antioxidant, anti-inflammatory and anticancer properties. The antimicrobial resistance is one of the major problems for global public health. Therefore, finding new organic structures with anti-microbial properties represents a challenging research field. In this study, antimicrobial screening of two Biginelli-based azo pyridone dyes has been carried out. The antimicrobial activity of synthe-tized dyes wasstudied against bacteria (Staphylococcus aureus, Escherichia coli) and yeast (Candida albicans), using agar diffusion method. The preliminary research results indicate the antimicrobial potential of the investigated compounds.

AB  - Halloysite nanotubes (HNTs), naturally occurring as aluminosilicate nanoclay mineral, have recently emerged as a possible nanomaterial for countless applications due to their specific chemical structure, tubular shape, high aspect ratio, biocompatibility and low toxicity. In this study, HNTs were incorporated into the epoxy resin matrix to improve its mechanical properties and thermal stability. However, heterogeneous size, surface charge and surface hydrogen bond formation, result in aggregation of HNTs in epoxies to a certain extent. Three specific techniques were used to integrate HNTs into neat epoxy resin (NE). The structure and morphology of the embedded nanotubes were confirmed by Fourier-transform infrared (FTIR) spectroscopy and X-ray diffraction (XRD). Tensile testing was carried out and the fractured surface of the tested specimen was analysed using scanning electron microscopy (SEM). The thermal stability of the prepared nanocomposite materials was investigated by thermogravimetric (TG) and derivative thermogravimetry (DTG) studies. The obtained results indicated that improved properties of HNTs/epoxy nanocomposite materials were related to the unique properties of well-dispersed HNTs, agglomerate scale, and reduced void presence, and could be controlled by the manufacturing processes.

The structure and morphology of the embedded nanotubes were confirmed by Fourier-transform infrared (FTIR) spectroscopy and X-ray diffraction (XRD). Tensile testing was carried out and the fractured surface of the tested specimen was analysed using scanning electron microscopy (SEM). The thermal stability of the prepared nanocomposite materials was investigated by thermogravimetric (TG) and derivative thermogravimetry (DTG) studies. The obtained results indicated that improved properties of HNTs/epoxy nanocomposite materials were related to the unique properties of well-dispersed HNTs, agglomerate scale, and reduced void presence, and could be controlled by the manufacturing processes.",

AB  - A series of nine 5-(4-substituted phenylazo)-3-amido-6-hydroxy-4-methyl-2-pyridones were synthesized and characterized by FT-IR, H-1 and C-13 NMR, UV-Vis, and PL spectroscopy. Photophysical properties of the dyes were examined in solvents of various polarities and at different pH values. The solvent effects on the absorbance and emission spectral shift were analyzed using Lippert-Mataga, Reichardt-Dimroth and Kamlet-Taft equations. Moreover, UV-Vis absorption and emission frequencies were correlated with Hammett substituent constants applying the linear free energy relationships. DFT calculations of the investigated dyes were accomplished to determine their structural and electronic properties.

AB  - Photocatalytic degradation of the carbamate insecticide methomyl and its commercial product Lannate-90 in aqueous suspension of TiO2 and ZnO using an Osram ultra-vitalux lamp (315-400 nm) was investigated. The objective of the investigation was to study and compare the rates of photochemical degradation of the pure active compound and its formulated product in order to find out the impact of inert ingredients on degradation processes. The photo-chemical degradation of pure methomyl was found to be slower than the degradation of its commercial product Lannate-90. Photodegradation was investigated by UV-Vis spectrometry and HPLC, while mineralization was monitored using IC and TOC analyses. Light absorption capabilities of catalysts were characterized by ultraviolet-visible diffuse reflectance spectroscopy method, while the stability of catalysts was studied by infrared analyses. Degradation products of methomyl and its formulated product were identified by high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) results and tentative photodegradation pathways were proposed.

AB  - Thermal degradation properties of 5-(4-substitutedphenylazo)-3-amido-6-hydroxy-4-methy1-2-pyridones and 5-(4-substitutedphenylazo)-3-cyano-6-hydroxy-4-methy1-2-pyridones dyes, differing in electron withdrawing and electron donating substitttents in para-position of diazo components were examined. The structure of the synthesized compourtds has been confirmed by H-1 NMR,C-13 NMR, FITR, UV-Vis and XRD analysis techniques. The results obtained with thermogravimetric analysis (TGA) - derivative thermogravimetry (DTG) and differential thermal analysis (DTA) were combined with GC-mass spectral fragmentation to obtain thermal decomposition mechanism. Non-isothermal kinetics were monitored by application of TGA-DTG-DTA. For Kinetic behavior of the investigated dyes during their degradation in an inert atmosphere, Kissinger, Ozawa, Flynn-Wall-Ozawa (FWO) and Kissinger-Alcahira-Sunose (KAS) isoconversional (model-free) methods were applied. It was found that different thermal stabilities of investigated dyes are the consequence of their different chemical structures, including diverse substituents.
