AB  - Indocyanine green (ICG) is the FDA-approved fluorescent dye used for in vivo medical imaging, diagnostics, and photothermal therapy. However, this dye is easily degradable in the human vascular system, and therefore its stabilization is preferable. In this work, ICG molecules were stabilized by their adsorption on the surface of the L-methionine-capped Ag and Au nanoparticles (Ag and Au @LM NPs) in aqueous colloidal dispersions. The result is the formation of hybrid metal core/ICG shell NPs in colloidal dispersions. Additionally, colloidal dispersions were stabilized, indicating a double effect of ICG adsorption. The obtained hybrid NPs were studied experimentally (UV–Vis spectrophotometry, HRTEM, DLS, FTIR) and theoretically (DFT calculations). HRTEM revealed that the interplanar spacing between adjacent planes of NPs decreases after the dye adsorption. The results obtained from the DFT study confirmed the formation of a covalent bond between the oxygen from ICG dye SO3− group and metal NPs. Considering the characteristics of both components of the NPs/ICG hybrid system, the authors assume that this hybrid system can exhibit the synergistic effect that could lead to more successful theranostic treatment of cancer in nanomedicine.

AB  - In this research, a composite based on montmorillonite (K10) modified with HDTMABr was used. The characterization of the pure K10, NaMMT and OMMT was performed using XRD, FTIR-ATR, SEM, TG, DTG, and DTA. Ion exchange capacity (CEC) and specific surface area (SSA) were also determined. The sulfite method was used to determine free and liberated formaldehyde (FA) from synthesized urea-formaldehyde/montmorillonite (UF/ MMT) composites. This research aims to demonstrate the bifunctionality of OMMT and that it can be used both for the capture of FA from the synthesized cross-linked UF resin and for the adsorption of the anionic dye Acid Red 183 (AR183) from aquatic medium. SEM analysis showed that there are changes in the morphology of the OMMT and the formation of a hollow network, which affects the absorption capacity of the clay. The calculated values of free and liberated FA in the UF/OMMT composites are drastically reduced and amount to 0.12% and 0.96%, respectively, compared to the composites with K10 (0.6% and 2.04%, respectively). Also, very promising results were obtained of the adsorption of AR183 dyes from the aquatic medium using OMMT. The results show that OMMT (0.5 g OMMT/50 cm3 aqueous dye solution, c=20 mgdm− 3 ) managed to remove 85.95% of AR183 dye (pH dye=7). The adsorption mechanism of AR183 on OMMT follows the Freundlich isotherm and proceeds according to the pseudo-first-order kinetic model. Overall, the findings of this work indicate that the use of the obtained OMMT has great potential in removing pollutants from two totally different systems.

AB  - The silver and gold L-methionine capped nanoparticles (Ag and Au @LM NPs) were analyzed as prospective acetylcholinesterase (AChE) inhibitors to test their potential in the treatment of cognitive impairment in depression and Alzheimer's disease. The stability of NPs, and their ability to inhibit AChE were studied by UV-Vis and FTIR spectrophotometry. At the same time, TEM and SEM measurements, DLS, and zeta potential measurements were employed in the structural characterization of NPs. Nearly spherical, negatively charged Ag and Au @LM NPs, with 17 nm and 31 nm in diameter, respectively, showed moderate inhibitory potential toward AChE in the given frame of investigated concentrations. For both NPs IC50 is not reached. Furthermore, the adsorption of enzyme molecules on the surface of Ag and Au @LM NPs was demonstrated. Hence, our assumption is that inhibition of AChE is caused by blockage of the enzyme‘s active site due to the steric hindrance of NPs.

AB  - In this work, betaine (trimethyl glycine) and tannin (complex biomolecules of polyphenolic nature) were used as bio-fillers. Urea-formaldehyde (UF) resin with a molar ratio of formaldehyde versus urea (FA/U) of 0.8 was synthesized in situ with tannin and betaine as bio-fillers, to obtain UF resin with reduced free FA content and increased hydrolytic and thermal stability by the principles of sustainability. The samples TUF (with tannin) and BUF (with betaine) were characterized by using X-ray diffraction analysis (XRD), non-isothermal thermogravimetric analysis (TGA), and differential thermal analysis (DTA), supported by data from Fourier Transform Infrared spectroscopy (FTIR) and Scanning electron microscopy (SEM). The percentage of free FA in modified BUF resin is 0.1%, while the percentage of free FA in tannin-modified resin is 0.8%. The hydrolytic stability of the modified UF resins was determined by measuring the concentration of liberated FA in the modified UF resins, after acid hydrolysis. The modified BUF resin is hydrolytically more stable because the content of released FA is 3.6% compared to the modified TUF resin, where it was 7.4%. Based on the value for T5%, the more thermally stable resin is the modified TUF resin (T5% = 123.1°C), while the value of the T5% for the BUF resin is 83.1°C. This work showed how UF bio-composite with reduced free FA content and increased hydrolytic and thermal stability can be obtained using tannin and betaine as bio-fillers.

The samples TUF (with tannin) and BUF (with betaine) were characterized by using X-ray diffraction analysis (XRD), non-isothermal thermogravimetric analysis (TGA), and differential thermal analysis (DTA), supported by data from Fourier Transform Infrared spectroscopy (FTIR) and Scanning electron microscopy (SEM). The percentage of free FA in modified BUF resin is 0.1%, while the percentage of free FA in tannin-modified resin is 0.8%. The hydrolytic stability of the modified UF resins was determined by measuring the concentration of liberated FA in the modified UF resins, after acid hydrolysis. The modified BUF resin is hydrolytically more stable because the content of released FA is 3.6% compared to the modified TUF resin, where it was 7.4%. Based on the value for T5%, the more thermally stable resin is the modified TUF resin (T5% = 123.1°C), while the value of the T5% for the BUF resin is 83.1°C. This work showed how UF bio-composite with reduced free FA content and increased hydrolytic and thermal stability can be obtained using tannin and betaine as bio-fillers.",

AB  - In this paper, the synthesis of modified urea-formaldehyde (UF) composites with differently activated montmorillonite KSF (UF/KSF) was performed. Two types of montmorillonite (MMT) KSF were used: sample activated with sulfuric acid-KSF(H2SO4) and sample activated with acid and stirring-KSF(H2SO4+stirrer). In order to examine the effect of KSF activation mode on the thermal and hydrolytic stability of UF resins, thermogravimetric analysis (TGA) was performed, as well as A determination of the amount of liberated formaldehyde (FA) after acid hydrolysis. Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) analysis were used to characterize the samples of modified UF/KSF composites and differently activated KSF. Activation of KSF led to a decrease in its specific surface area (SSA) and to an increase in cation exchange capacity (CEC). SEM analysis showed that in the KSF(H2SO4+stirrer) sample, the layered microstructure was disrupted. Free formaldehyde was not detected in the sample of UF resin with KSF(H2SO4), and in the sample with KSF(H2SO4+stirrer) it was 0.06%. The UF/KSF(H2SO4) composite showed higher hydrolytic stability (3.9%) compared to UF/KSF(H2SO4+stirrer) (4.62%), but lower compared to the UF/KSF(inactive) (1.23%). TG analysis showed that the KSF(H2SO4) sample had better thermal stability than the KSF(H2SO4+stirrer) sample, but this did not contribute to the better thermal stability of UF/KSF(H2SO4) compared to UF/KSF(H2SO4+stirrer), both samples had a T5% value of 112 °C.

AB  - Urea-formaldehyde (UF) resins are the leading adhesive in the wood industry. Their disadvantages are low water resistance and formaldehyde (FA) emissions from wood panels due to the low stability of the amino-methylene bond. Since FA has a detrimental effect on the environment and human health, the main goal of the modern adhesives industry is to produce efficient UF adhesives with low amounts of emitted, if not without, FA. One way to achieve this is to add a formaldehyde scavenger. In this work, UF resins modified with zeolite type ZSM-5 and bentonite as free FA scavengers are analyzed and compared. A total of three UF resins were synthesized: pure UF resin (UF), UF composite containing zeolite (ZUF), and bentonite (BUF) under the same conditions. Specific surface area (SSA) and cation exchange capacity (CEC) for bentonite and zeolite were determined. SSA (Sears' method) for bentonite is 19.9 m2/g and for zeolite 39.1 m2/g. The CEC of bentonite is 0.68 mol/kg, and that of zeolite is 0.1 mol/kg. The disulfide method was used to determine free FA in modified UF resins. The amount of free FA in the ZUF composite is 0.06%, while in the BUF composite is 0.18%. The hydrolytic stability of modified UF resins was determined by measuring the amount of liberated FA in the modified UF resins after acid hydrolysis. The results show that the amount of released FA in the ZUF composite is 4.08%, while in the BUF resin, it is 4.8%. Based on the obtained results, it can be concluded that zeolite is a better scavenger of free FA than bentonite and that its ZUF composite is hydrolytically more stable than the BUF composite.

AB  - In this study, the thermal and hydrolytic properties of composite systems based on the urea–formaldehyde resin (UF) and eco-friendly montmorillonite (K10) as formaldehyde (FA) scavenger were examined. UF resin with molar ratio FA:U = 0.8 was synthesized in situ with inactivated, and activated K10. K10 was activated by sulfuric acid (H2SO4) with and without magnetic stirring. The samples are marked with $${\mathrm{K}10}_{\left({\mathrm{H}}_{2}{\mathrm{SO}}_{4}\right)}$$,$${\mathrm{K}10}_{{\left({\mathrm{H}}_{2}{\mathrm{SO}}_{4 }\right)}_{\mathrm{ST}}}$$, $${\mathrm{UF}/\mathrm{K}10}_{\left({\mathrm{H}}_{2}{\mathrm{SO}}_{4 }\right)}$$, and $${\mathrm{UF}/\mathrm{K}10}_{{\left({\mathrm{H}}_{2}{\mathrm{SO}}_{4 }\right)}_{\mathrm{ST}}}$$, respectively. X-ray diffraction analysis and non-isothermal thermogravimetric analysis, supported by data from Fourier transform infrared spectroscopy and scanning electron microscopy were used to characterize the samples. Based on the measurement of specific surface area (SSA), the degree of activation was determined. Measurement of the SSA shows that higher values were obtained for modified K10 compared to inactive K10. The amount of free and liberated FA was 0.06% and 4.6% for $${\mathrm{UF}/\mathrm{K}10}_{\left({\mathrm{H}}_{2}{\mathrm{SO}}_{4 }\right)}$$and 0.12% and 4% for $${\mathrm{UF}/\mathrm{K}10}_{{\left({\mathrm{H}}_{2}{\mathrm{SO}}_{4 }\right)}_{\mathrm{ST}}}$$. This research showed that the $${\mathrm{UF}/\mathrm{K}10}_{\left({\mathrm{H}}_{2}{\mathrm{SO}}_{4 }\right)}$$composite has a lesser amount of free FA (0.06%) in comparison to the $${\mathrm{UF}/\mathrm{K}10}_{{\left({\mathrm{H}}_{2}{\mathrm{SO}}_{4 }\right)}_{\mathrm{ST}}}$$composite (0.12%). The $${\mathrm{UF}/\mathrm{K}10}_{{\left({\mathrm{H}}_{2}{\mathrm{SO}}_{4 }\right)}_{\mathrm{ST}}}$$composite has a higher resistance to acidic hydrolysis. The modified $${\mathrm{UF}/\mathrm{K}10}_{\left({\mathrm{H}}_{2}{\mathrm{SO}}_{4}\right)}$$composite is more thermally stable than $${\mathrm{UF}/\mathrm{K}10}_{{\left({\mathrm{H}}_{2}{\mathrm{SO}}_{4 }\right)}_{\mathrm{ST}}}$$composite.

AB  - Fig (Ficus carica L.) is a fruit of the Moraceae family, which is mostly grown in subtropical regions, but also grows in Serbia. Fig trees are usually grown in warm and dry climates. According to the FAO world production of figs is stable, with a decade-long average of about 1.1 million tons a year. Fig pomace are formed after fermentation of this fruit which is used for the preparation of brandy. The brandy industry generates huge amounts of pomace as industrial waste, so pyrolysis as thermochemical technologies was used for organic agro-industrial waste treatment. Biochar produced by pyrolysis of fig pomace at 500 °C were characterized and investigated as adsorbents for the removal of Pb2+ ions from aqueous solution. Fig pomace before and after pyrolysis was characterized using proximate, inorganic and elemental analysis, Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), X-ray diffraction (XRD), thermogravimetric analysis (TGA) and differential thermal analysis (DTA). Biochar has a carbon matrix with a high degree of porosity and large surface area, suggesting that it can be used as a surface adsorbent and thus have a significant role in controlling environmental contaminants. The surface modification by gamma irradiation was done to enhance the adsorption capacity of biochar. The Pb2+ ions contents in aqueous solution were analyzed using ICP-OES. The adsorption capacity was estimated using the Freundlich and Langmuir model. The results of this work suggest that pyrolysis and irradiation of biomass is a promising way to produce efficient heavy metal sorbents for waste-water treatment.

AB  - The effect of different montmorillonites (KSF and K10) and their modifications (Na-KSF, Na-K10) on content of formaldehyde-FA (free and liberated) modified urea-formaldehyde (UF) composites was investigated. KSF and K10 were modified by sodium chloride (NaCl). A total of four samples were synthesized, with the designations UF/KSF, UF/Na-KSF, UF/K10, and UF/Na-K10, under the same conditions. The content of free FA was determined by the bisulfite method. The hydrolytic stability of modified UF resin was determined by measuring the concentration of liberated FA of modified UF composites after acid hydrolysis. The specific surface area of the tested montmorillonites was determined by the Sear's method. Higher values of specific surface area were obtained for pure KSF (149.4 m2/g) compared to modified Na-KSF (48.6 m2/g). Specific surface area for pure K10 was 111 m 2/g, compared to value of 71 m2/g for modified Na-K10. The amount of free and liberated FA was 0.4%, 0.12% and 1.2% and 2.3%, respectively for UF/KSF and UF/Na-KSF composite. The values for free FA for UF/K10 and UF/Na-K10 composite are the same and amount to 0.6%. It was concluded that the UF/Na-KSF composite has a smaller content of free FA (0.12%) compared to other UF composites. The UF/KSF composite has a higher resistance to acidic hydrolysis and lower liberated FA percent (1.2%).

AB  - Urea-formaldehyde (UF) composites with a formaldehyde/urea (FA/U) ratio = 0.8 and different particle sizes of montmorillonite (MMT), namely UF/KSF and UF/K10 were synthesized. The hydrolytic stability of modified UF composites was determined by measuring the content of the liberated formaldehyde of modified UF composites after acid hydrolysis. The synthesized modified UF composites were irradiated (50 kGy) and the effect of γ–irradiation was evaluated on the basis of these thermal behaviors. The thermal behavior was studied by non-isothermal thermo-gravimetric analysis (TG), differential thermo-gravimetry (DTG), and differential thermal analysis (DTA) supported by data from Fourier transform infrared spectroscopy (FTIR). The minimum percentages of free (0.4%) and liberated (1.2%) formaldehyde were obtained in the UF/KSF composite. The modified UF/KSF composite shows better radiation resistance than the modified UF/K10 composite. The shift of temperature values for the selected mass losses (T5%) to higher temperatures indicates an increase in the thermal stability of the UF/K10 composite after γ–irradiation. γ–irradiation causes a decrease in the absorption intensity of bands in the FTIR spectrum of a modified UF/KSF composite and an increase in the absorption intensity of bands in the FTIR spectrum of a modified UF/K10 composite. © 2022 Elsevier Ltd

AB  - The homemade, porous carbon material, thermolysis prepared from Novolac phenol-formaldehyde resin, in situ modified with Co3O4 nanoparticles and mixed with single-wall carbon nanotubes, was used in selective sensing of prominent antioxidant α-lipoic acid (LA). XRD, SEM and EIS measurements were used for characterization of material composition, structure, morphology and improved conductivity. The quantification of LA at TPCo3O4&SWCNTCPE was done by a square-wave voltammetric technique in BR buffer solution at pH 6. The linear working range was recorded from 2 to 100 μM of LA and the proposed electrode material was successfully applied in the determination of LA in dietary supplements.

AB  - The goal of this work was to develop green electrode material that unites all advantages of domestic made, synthesized porous carbon powder and ceria dioxide nanoparticles known due to exceptional catalytic properties. Thermal decomposition of Novolac phenol-formaldehyde resin and cerium sulfate resulting in producing a high-performance CeO2 porous carbon material highly sensitive to dopamine (DA) electrooxidation. Morphological and structural characteristics of the material were determined by SEM and XRD measurements, while electrochemical characterization was performed by EIS and CV. The sensitivity of DA determination on the proposed CeO2-doped carbon material was enhanced by adding multi-wall carbon nanotubes to finally prepare a mixture for a specific carbon paste electrode (TPCeO2&MWCNT@CPE). SWV technique was used for quantification of dopamine in Britton-Robinson buffer pH 6 in the concentration range of 0.5-100 μM of DA, with the detection limit of 0.14 μM and quantification limit of 0.44 μM. Good selectivity overstudied bioactive compounds enables the successful and efficient application of the proposed electrode and developed an analytical procedure for the determination of dopamine in spiked urine samples.

AB  - Urea-formaldehyde resin (F/U ratio of 0.8)/thermally activated montmorillonite (UF/Delta TK10) nanocomposite was synthesized. The hydrolytical, thermal, and UV radiation stability of UF/Delta TK10 nanocomposites are determined. UF hybrid nanocomposites have been irradiated with UV light with a wavelength of 254 nm and 366 nm, and after that, their radiation stability was evaluated. The free formaldehyde (FA) percentage in all prepared samples was determined. The sample was characterized by using X-ray diffraction analysis (XRD), nonisothermal thermogravimetric analysis (TGA), differential thermal analysis (DTA), and differential thermal gravimetry (DTG), with infrared (FTIR) spectroscopy. Crosslinked UF/Delta TK10 nanocomposite shows the highest resistance to acid hydrolysis after UV irradiation at a wavelength of 254 nm. The values for T-5% are identical for the unirradiated and UV irradiated (wavelength of 366 nm) UF/Delta TK10 nanocomposite. It can be concluded that this sample is thermally most stable and shows good resistance to UV irradiation.
