AB  - A new formulation that gradually released encapsulated Thuja plicata essential oil (TPEO) as an active component from a biopolymer matrix within a given period was obtained. Antimicrobial activity was determined in in-vitro tests where pure TPEO successfully inhibited the development of different Phytophthora species. The TPEO essential oil was encapsulated into the biopolymer matrix and an oil-in-water emulsion was formed. FTIR spectra analysis confirmed the formation of electrostatic interaction between these polymers, and hydrogen interactions between active components of TPEO and polymer chains. The stability of the emulsions was confirmed by zeta potential measurements, with a value of about 30 mV, even after 14 days of aging. UV-Vis spectra analysis revealed that  gt 60% of TPEO remained in the emulsion after 14 days of exposure to ambient conditions, whereas pure TPEO evaporated faster, and around 20 % remained after 6 days. Encapsulated TPEO almost completely inhibited the growth of Phytophthora species during the ten-day day's exposition being statistically significantly improved compared to fungicide treatment. It was demonstrated that the emulsion exhibited a prolonged antimicrobial effect and successfully suppressed the growth of Phytophthora species, and can be considered as a means of protection in forests and crops.

AB  - Dripping rainfall simulators (DRS) for soil research generate water drops with different types of drippers, but metal tubes are most commonly used, often in the form of hypodermic needles. However, scientific papers using dripping rainfall simulators are often incomplete in terms of data on hypodermic needle characteristics, as well as data on drops produced by hypodermic needles under different water pressures. This study determines which drop sizes and dripping speeds are generated by various hypodermic needles at different water pressures. For the purpose of this study, a dripping rainfall simulator was designed and constructed for laboratory use. Water drops were generated with 11 different needles, ranging in size from 16 G to 32 G (tube gauge number), at different water pressures. Measured water drop sizes ranged from 1.42 to 3.69 mm at a dripping speed between 10 and 360 drops per minute and water head from 14 to over 1970 mm. Measured drop sizes, supplemented with data from previous studies, provided information on the relation between drop sizes and the size of the hypodermic needles. Van Boxel's numerical model provided estimations of the fall velocity for different drop diameters and their kinetic energy for falling heights up to 11.5 m. The results of this research can be used to design dripping rainfall simulators for soil research.

AB  - The possibility of producing and designing bio-epoxides based on the natural polyphenol lignin/epoxidized lignin and tannic acids for application as wood adhesives is presented in this work. Lignin and tannic acids contain numerous reactive hydroxyl phenolic moieties capable of being efficiently involved in the reaction with commercial epoxy resins as a substitute for commercial, non-environmentally friendly, toxic amine-based hardeners. Furthermore, lignin was epoxidized in order to obtain an epoxy lignin that can be a replacement for diglycidyl ether bisphenol A (DGEBA). Cross-linking of bio-epoxy epoxides was investigated via FTIR spectroscopy and their prospects for wood adhesive application were evaluated. This study determined that the curing reaction of epoxy resin can be conducted using lignin/epoxy lignin or tannic acid. Tensile shear strength testing results showed that lignin and tannic acid can effectively replace amine hardeners in epoxy resins. Examination of the failure of the samples showed that all samples had a 100% fracture through the wood. All samples of bio-epoxy adhesives displayed significant tensile shear strength in the range of 5.84-10.87 MPa. This study presents an innovative approach to creating novel cross-linked networks of eco-friendly and high-performance wood bio-adhesives.

AB  - Styrene-butadiene (SBR) and acrylonitrile-butadiene (NBR) rubber blends with tetramethyl thiuram disulfide (TMTD) and tetramethyl thiuram monosulfide (TMTS) accelerators and environmentally friendly plasticizers, obtained from PET recycling and biobased resources (LA/PG/PET/EG/LA), were prepared. The mechanical properties of the obtained rubber products were tested and compared with those of commercial dioctyl terephthalate (DOTP). TMTS was prepared by simple and efficient one-pot synthesis from dimethylamine, carbon disulfide, potassium cyanide, and ammonium chloride as catalysts in recycled isopropanol/water azeotrope as solvent. In a comparative study, methoxide, ethoxide, iodide, and amide ions were also used. The two-step reaction mechanism of TMTS synthesis involves the oxidation of the amine salt of dimethyldithiocarbamic acid to TMTD by hydrogen peroxide and sulfur elimination from the TMTD disulfide bond. Potassium cyanide appears to be the most efficient nucleophile. The simplicity of operation, mild reaction conditions, solvent recycling, high yields, and applicability to the industrial level are the advantages of this process. Shore hardness, tensile strength, and compression test results of vulcanized blends before and after aging showed similar properties for both accelerators, while somewhat better results were obtained with LA/PG/PET/EG/LA plasticizer.

AB  - It is necessary to harmonize the needs of society in terms of agricultural production and land protection from various forms of degradation throughout sustainable land management. Assessing the justification of investment in sustainable management of land resources is an important step in this process. Consequently, an analysis of soil erosion risk was carried out in the suburban area of the morphological unit of the Baricka river watershed, using the Revised Universal Soil Loss Equation (RUSLE) method, with the existing and projected structure of agricultural production according to the Future Agricultural Production Structure Model from the Aspect of Preserving Land Resources for Mountain Catchment Areas of Serbia (FAPSMS). The value of the existing and projected production structure from an economic aspect was also examined using dynamic economic methods. In order to assess the risk and uncertainty of investments, a sensitive analysis of dynamic methods was carried out. The results show that soil erosion losses are already below tolerance values with the existing production structure and that they could be reduced even more by applying the designed structure. Economic indicators show that the investment is justified and that it is more sensitive to changes in income.

AB  - U ovom radu ispitivan je potencijal korišćenja akril-funkcionalizovanog kraft lignina (AKL) u smanjenju zapaljivosti polimernih kompozita na bazi recikliranih nezasićenih poliesterskih smola (NZPS). Akrilna funkcionalizacija kraft lignina je izvedena direktnom esterifikacijom slobodnih polifenolnih grupa sa akriloil hloridom, nakon čega je AKL umešan u NZP smolu sintetizovanu od poliola dobijenih katalitičkom depolimerizacijom otpadnog poli(etilen tereftalata). AKL je homogenizovan sa NZPS pri različitim masenim udelima: 2,5, 5,0, 7,5 i 12,5 mas.%. Strukturne i dinamičko-mehaničke karakteristike akril-funkcionalizovanog kraft lignina i kompozita određene su primenom FTIR spektroskopije, dinamičkomehaničke analize (DMA) i testova jednoosnog zatezanja. Proučavan je uticaj funkcionalizacije i masenog udela AKL na zatezna i termička svojstva NZPS. Vatrootporna svojstva kompozita su ispitivana prema standardnoj UL-94V metodi, na osnovu koje je kompozit sa 12,5 tež. % akril-funkcionalizovanog lignina dostigao najvišu kategorija toplotno otpornih materijala.
AB  - This paper investigates the using potential of acryl-functionalized kraft lignin (AKL) in reducing the flammability of polymer composites based on recycled unsaturated polyester resins (UPR). Acryl functionalization of kraft lignin was performed by direct esterification of free polyphenolic groups with acryloyl chloride, after what, the AKL was blended in UPR resin synthesized from the polyols obtained by catalytic depolymerization of waste poly(ethylene terephthalate). The AKL was homogenized in UPR resin in different weight ratios: 2.5, 5.0, 7.5, and 12.5 wt.%. Structural and dynamic-mechanical characteristics of acryl-functionalized kraft lignin and composites were determined using FTIR spectroscopy, dynamicmechanical analysis (DMA), and tensile tests. The influence of functionalization and mass fraction of AKL on tensile and thermal properties of UPR resin was studied. The thermal properties of the composite were tested according to the standard UL-94 method, based on which the highest category of heat-resistant materials is a composite with 12.5 wt.% acylfunctionalized lignin.

abstract = "U ovom radu ispitivan je potencijal korišćenja akril-funkcionalizovanog kraft lignina (AKL) u smanjenju zapaljivosti polimernih kompozita na bazi recikliranih nezasićenih poliesterskih smola (NZPS). Akrilna funkcionalizacija kraft lignina je izvedena direktnom esterifikacijom slobodnih polifenolnih grupa sa akriloil hloridom, nakon čega je AKL umešan u NZP smolu sintetizovanu od poliola dobijenih katalitičkom depolimerizacijom otpadnog poli(etilen tereftalata). AKL je homogenizovan sa NZPS pri različitim masenim udelima: 2,5, 5,0, 7,5 i 12,5 mas.%. Strukturne i dinamičko-mehaničke karakteristike akril-funkcionalizovanog kraft lignina i kompozita određene su primenom FTIR spektroskopije, dinamičkomehaničke analize (DMA) i testova jednoosnog zatezanja. Proučavan je uticaj funkcionalizacije i masenog udela AKL na zatezna i termička svojstva NZPS. Vatrootporna svojstva kompozita su ispitivana prema standardnoj UL-94V metodi, na osnovu koje je kompozit sa 12,5 tež. % akril-funkcionalizovanog lignina dostigao najvišu kategorija toplotno otpornih materijala., This paper investigates the using potential of acryl-functionalized kraft lignin (AKL) in reducing the flammability of polymer composites based on recycled unsaturated polyester resins (UPR). Acryl functionalization of kraft lignin was performed by direct esterification of free polyphenolic groups with acryloyl chloride, after what, the AKL was blended in UPR resin synthesized from the polyols obtained by catalytic depolymerization of waste poly(ethylene terephthalate). The AKL was homogenized in UPR resin in different weight ratios: 2.5, 5.0, 7.5, and 12.5 wt.%. Structural and dynamic-mechanical characteristics of acryl-functionalized kraft lignin and composites were determined using FTIR spectroscopy, dynamicmechanical analysis (DMA), and tensile tests.

AB  - The characterization and cleanup of groundwater contamination in hazardous-waste sites are of significant engineering and scientific importance. This study analyzes biodegradation fingerprints in groundwater, 25 years after the accidental leakage of kerosene (jet fuel) at the site in central Serbia. The long-term existence of hydrocarbon contamination and the presence of indigenous microbiological populations capable of biodegradation have been confirmed by the results of GCxGC-MS chromatography and microbiological characterization. Total petroleum hydrocarbons (TPH), geochemical indicators, and other parameters were spatially analyzed to provide insight into biodegradation occurrence. The lowest concentrations of electron acceptors (O-2, NO3-, and SO42-) and the highest concentrations of microbial metabolic products (Mn and Fe) overlap in the piezometers closest to the source of contamination, due to the occurrence of different biodegradation mechanisms. Based on the analysis of redox-sensitive compounds, the mixed oxic-anoxic processes in groundwater also correspond to the aforementioned zone, as confirmed by the redox potential (Eh) measurements. The results of cross-study analysis reveal further reduction of hydrocarbon contamination, the occurrence of less anoxic redox processes, and the increase of oxic conditions in groundwater. Overall, the results provide clear evidence of the biodegradation effects in groundwater and insight into their evolution under natural attenuation processes.

AB  - Derivatives of thiocarbohydrazone studied so far have shown great biological activity such as antioxidant, antimicrobial, and anticancer. Most of these compounds are bis-substituted derivatives, while monothiocarbohydrazones are much less investigated. Eighteen monothiocarbohydrazones were synthesized and subjected to physicochemical characterization in order to facilitate the examination of their potential biological activity and application in future studies. The structure of synthesized derivatives was confirmed with NMR and FT-IR spectroscopy, and with elemental analysis. For one of the compounds, single-crystal X-ray diffraction analysis was performed. Specific and non-specific molecular interactions were interpreted by LSER principles, using Catalan's model. For additional information about the dominance and influence of the interactions presented, correlations with Hansen's solubility parameters were calculated. Influence of the type and position of the substituent on absorption maxima was determined with LFER (linear free-energy relationship) principles, using Hammett's equation. Acidity constants of the synthesized compounds were theoretically calculated and experimentally determined. Moreover, the excitation of a molecule by a photon of UV-Vis light was interpreted by time-dependent density functional theory (TD-DFT) calculations of UV absorption bands, and intramolecular charge transfer (ICT) was quantified by calculations of the charge transfer distances (D-CT).
