AB  - Vaccinium myrtillus L.(Ericaceae), a perennial, wild, and small deciduous shrub that grows in the mountains and forests of Europe, contains anthocyanins, phenolic acids, flavonoids, fatty acids, stilbenes, iridoid glycosides, dietary fibers, vitamins, and minerals. The leaves' extracts are widely used in traditional medicine due to their astringent, antiseptic, antioxidant, anti-inflammatory, skin-rejuvenating, lipid-lowering, hypolipidemic, and hypoglycemic activities. The novel extraction techniques, including ultrasound-assisted extraction, provide various benefits, such as reducing solvent consumption and extraction time and increasing extraction yield, and quality. Hence, in the present study, V. myrtillus extracts were prepared using dried leaves (0.66 g), 50% ethanol as the extraction solvent (20 mL), and maceration (60 min) or ultrasound-assisted extraction (ultrasound probe, amplitude of 60% for 5 min). The obtained extracts were examined in terms of total polyphenol content (TPC) and antioxidant activity (ABTS, DPPH, FRAP, and CUPRAC assays). The TPC of the extract prepared using maceration was 55.2±0.7 mg gallic acid equivalents (GAE)/g of plant material, while the TPC of the extract prepared using an ultrasound probe was 55.6±1.0 mg GAE/g. The DPPH radical scavenging activities of the extracts correlated with the TPC and amounted to 1.81±0.05 mg/mL for macerate and 1.79±0.02 mg/mL for the extract obtained using an ultrasound probe, whereas ABTS antioxidant capacity did not correlate with the polyphenol concentration, 31.4±0.9 µmol Trolox equivalents (TE)/g for the macerate and 43.4±1.1 µmol TE/g for the extract from the ultrasound-assisted extraction. According to the results of FRAP and CUPRAC assays, the antioxidant potential was similar for both extracts (15.3±0.2 and 15.5±0.2 µmol Fe2+/g and 45.7±0.5 and 46.0±0.7 µmol TE/g, respectively). Due to higher ABTS radical scavenging potential and significantly shorter extraction time, V. myrtillus extract prepared using an ultrasound probe was favored. The present research was an initial step in the preparation of V. myrtillus extracts which can be potentially implemented in food, pharmaceutical, and cosmetic formulations.

AB  - Liposome-encapsulated folic acid was incorporated into the films made from sodium carboxymethyl cellulose (CMC) (2 mas%) and a mixture of carboxymethyl cellulose and solagum (9:1 w/w) using the film-forming cast solution method. Histidine was used to increase solubility for folic acid in liposomes (1-5 mg/ml), and propylene glycol was used as a film plasticizer (2.6 mas%). The obtained films (50-60 µm tick) containing 3.12-20.19 mg of folic acid per gram of film are envisaged to be used as patches for transdermal delivery of folic acid. Therefore, some physical, mechanical, release and structural attributes of the films were scrutinized. Folic acid gave yellow color to the films and contributed to stronger chemical bonds which resulted in improved strength of the film. Liposomes prolonged the release of folic acid from films to 24 h without adverse effects on mechanical properties of the films, but degraded homogeneity of the films, which could be ascribed to its agglomeration within the film matrix as revealed by AFM. According to the release at pH 5.5, the film formulation based on a blend of CMC and solagum containing 3 mg/ml liposome-encapsulated folic acid is recommended from the point of view of release kinetics determined by its solubility.  Practical application: Folic acid is effective in reducing oxidative stress levels in the skin and neutralizing the harmful free radicals and is also essential for various metabolic reactions in the body. However, the limited solubility of folic acid linked with its poor absorption in an organism, low storage stability, short half-life upon oral consumption, specific food preferences of some people, extensive liver metabolism, and pregnancy-induced vomiting point to a large potential in transdermal usage of folic acid. This has motivated us to design new multicomponent polymer-lipid systems as an alternative solution to overcome some of these drawbacks. The results obtained for these multicomponent films pointed to their potential for prolonged release of folic acid to 24 h, which can also be useful for scientists interested in encapsulating similar poorly soluble compounds in CMC patches. The finding can be also valuable information for pharmaceutical manufacturers and scientists worldwide.

AB  - U ovom radu prikazana je ekstrakcija latica hibrida Paeonia lactiflora "Činija lepote" i Calendula officinalis L. pomoću mikrotalasnog reaktora i ultarazvuka u sistemu etanol-voda, kao i izolacija etarskog ulja latica Calendula officinalis L. hidrodestilacijom. Određen je ukupan sadržaj fenola i flavonoida u ekstraktima i ulju, i procenjena je antioksidativna aktivnost. Antioksidativna aktivnost je određena korišćenjem standardnih, antioksidativnih in vitro DPPH • i ABTS •+ testova. Najveći ukupni sadržaj fenola utvrđen je kod ekstrakata P. lactiflora i C. officinalis L. dobijenih ultrazvučnom ekstrakcijom (83,16 i 114,47 mg GA/g, redom), dok je najveći sadržaj flavonoida dobijen ekstrakcijom uz pomoć mikrotalasnog reaktora (123,48 i 65,29 mg QE/g, redom). Najveća antioksidativna aktivnost za ekstrakt hibrida Paeonia lactiflora "Činija lepote" dobijena je mikrotalasnom ekstrakcijom (79% i 83%), dok je za ekstrakt Calendula officinalis L. dobijena ultrazvučnom ekstrakcijom (45% i 49%) u DPPH • i ABTS •+ , redom. U cilju poboljšanja antioksidativne aktivnosti oba tipa ispitivanih analita (ekstrakta i etarskog ulja), pektinski biopolimerni film, (u formi nosača), u procesu enzimski potpomognute katalize, je pripremljen. Za karakterizaciju dobijenih filmova korišćena je optička mikroskopija i FTIR spektroskopija. Filmovi sa esencijalnim uljem C. officinalis L. i galnom kiselinom, pokazali su značajno povećan procenat inhibicije u DPPH • i ABTS •+ testu (91% i 95%, redom) nakon 10 minuta. Rezultati su, takođe, pokazali da se sve formulacije pektinskog biopolimernog filma, modifikovanog galnom kiselinom, mogu uspešno primenjivati kao nosač za oba tipa ingredijenata.
AB  - In this study, the petals collected from peony hybrid Paeonia lactiflora "Bowl of Beauty" and Calendula officinalis L. were extracted using an ethanol-water mixture assisted with microwave and ultrasonic treatment. The isolation of Calendula officinalis L. essential oil was done by hydrodistillation as well. The total phenolic and flavonoids content in the extracts and oil were determined and their antioxidant activity was evaluated. The highest total phenolic content was found for the extracts of hybrid Paeonia lactiflora and Calendula officinalis L. obtained by ultrasound extraction (83.16 and 114.47 mg GA/g, respectively), while the flavonoid content obtained by microwave-assisted extraction was relatively high (123.48 and 65.29 mg QE/g, respectively). The highest antioxidant activity was obtained in DPPH • and ABTS •+ assay for the microwave-assisted extraction of hybrid P. lactiflora (79% and 83%) and ultrasound-assisted extraction of C. officinalis L. (45% and 49%), respectively. To improve antioxidant activity of both types of examined analytes (extracts and essential oil), the pectin biopolymer film (as a carrier) was prepared in the process of enzymatically assisted catalysis. Optical microscopy and FTIR spectroscopy were used for the characterization of obtained materials. The films, with essential oil of C. officinalis L. and gallic acid, showed significantly increased percentage inhibition in DPPH • and ABTS •+ test (91% and 95%, respectively) after 10 minutes. The results, also, showed that all formulations of pectin biopolymer film, modified with gallic acid, can be successfully applied as a carrier for both types of ingredients.

AB  - The aim of this study was to investigate covalent immobilization of horseradish peroxidase (HRP) on magnetic nanoparticles (Mag) encapsulated in calcium alginate beads (MABs) for color degradation, combining easy and fast removal of biocatalyst from the reaction mixture due to its magnetic properties and strong binding due to surface alginate functional groups. MABs obtained by extrusion techniques were analyzed by optical microscopy, FEG-SEM and characterized regarding mechanical properties, magnetization and HRP binding. HRP with initial concentration of 10 mg/gcarrier was successfully covalently bonded on MABs (diameter ~1 mm, magnetite/alginate ratio 1:4), with protein loading of 8.9 mg/gcarrier, immobilization yield 96.9% and activity 32.8 U/g. Immobilized HRP on MABs (HRP-MABs) was then used to catalyze degradation of two anthraquinonic dyes, Acid Blue 225 (AB225) and Acid Violet 109 (AV109), as models for wastewater pollutants. HRP-MABs decolorized 77.3% and 76.1% of AV109 and AB225, respectively after 15 min under optimal conditions (0.097 mM H2O2, 200 mg of HRP-MABs (8.9 mg/gcarrier), 0.08 and 0.1 g/mg beads/dye ratio for AV109 and AB225, respectively). Biocatalyst was used for 7 repeated cycles retaining 75% and 51% of initial activity for AB225 and AV109, respectively, showing potential for use in large scale applications for colored wastewater treatment.

AB  - Enzymatic hydrolysis of food proteins is convenient method to improve their functional properties and physiological activity. Herein, the successful covalent attachment of alcalase on alginate micron and submicron beads using the carbodiimide based chemistry reaction and the subsequent application of the beads for egg white and soy proteins hydrolysis were studied. In addition to the electrostatic extrusion technique (EE) previously used by others, the potential utilization of a novel ultrasonic spray atomization technique without drying (UA) and with drying (UAD) for alginate submicron beads production has been attempted. The immobilization parameters were optimized on microbeads obtained by EE technique (803 +/- 23 mu m) with respect to enzyme loading and alcalase activity. UA and UAD techniques resulted in much smaller particles (607 +/- 103 nm and 394 +/- 51 nm in diameter, respectively), enabling even higher enzyme loading of 671.6 +/- 4 mg g(-1) on the carrier and the highest immobilized alcalase activity of 2716.1 IU g(-1) in the standard reaction. The UAD biocatalyst exhibited also better performances in the real food system based on egg white or soy proteins. It has been shown that the immobilized alcalase can be reused in seven successive soy protein hydrolysis cycles with a little decrease in the activity.

AB  - In this study, development of folic acid-loaded liposomes using a basic amino acid, histidine as a solubilizing agent for folic acid was presented, which tackled the poor solubility of this vitamin. The effect of the liposomal membrane modifiers, cholesterol and SPAN 20 on the characteristics of the final formulations was examined. Liposomes prepared from a commercially available purified soybean lecithin (Phospholipon 90G) by proliposome method were between 503 and 877 nm in average diameter, where cholesterol induced enlargement and SPAN.20 reduction of vesicles. High encapsulation efficiency of 84% and drug loading of 0.123 mg g−1 were achieved, irrespective to the composition. According to AFM images, folic acid-loaded liposomes of a fraction with a nano size were flattened compared to globular empty liposomes. FTIR analysis revealed possible interactions between phospholipids and histidine, while DSC study suggested interactions between folic acid and lipids during heating. Release study done by a Franz diffusion cell showed prolonged release of folic acid from liposomes and the release rate was determined by folic acid solubility.

AB  - In order to reduce the usage of fossil fuels in industrial sectors by meeting the requirements of production processes, new heat integration and heat recovery approaches are developed. The goal of this study is to develop an approach to increase energy efficiency of an industrial zone by recovering and reusing waste heat via indirect heat integration. Industrial zones usually consist of multiple independent plants, where each plant is supplied by an independent utility system, as a decentralized system. In this study, a new approach is developed to target minimum energy requirements where an industrial zone would be supplied by a centralized utility system instead of decentralized utility system. The approach assumes that all process plants in an industrial zone are linked through the central utility system. This method is formulated as a linear programming problem (LP). Moreover, the proposed method may be used for decision making related to energy integration strategy of an industrial zone. In addition, the proposed method was applied on a case study. The results revealed that saving of fossil fuel could be achieved.

AB  - In this study, alcalase (protease from Bacillus licheniformis) immobilization by adsorption, enzyme crosslinking and covalent enzyme binding to activated chitosan microbeads were examined. The biocatalysts highest activity was obtained by covalent immobilization of alcalase onto a solid support. The alcalase covalent immobilization onto different types of chitosan beads obtained by inverse emulsion technique and electrostatic extrusion was studied. Parameters examined under different conditions were beads diameter, enzyme loading, enzyme capacity yield, and biocatalyst activity. The highest activity and enzyme loading of 23.6 IU/mg protein and 340.2 mg/g, respectively, were achieved by the enzyme immobilized onto chitosan microbeads obtained by the electrostatic extrusion technique. FT-IR analysis was used to confirm formation of alcalase-chitosan conjugates. The activity of optimally produced alcalase-chitosan microbeads was then verified in the industrially feasible reaction systems of egg white and soy protein hydrolysis. The high degree of hydrolysis of 29.85 +/- 0.967% after 180 min and five successive reuses obtained under real conditions (50 A degrees C, pH 8) verified the covalently bound alcalase to chitosan beads a promising candidate for use in industrial egg white protein hydrolysis process.

AB  - Despite the fact that Thymus serpyllum is well-known medicinal plant and its chemical profile and biological activity have been investigated, there is no detailed study regarding the influence of different techniques and conditions on the extraction of polyphenolic compounds from Serpylli herba. The aim of this study was optimization of the extraction parameters that improves the efficiency of polyphenols extraction from T. serpyllum: particle size, solid-to-solvent ratio, solvent type and extraction time, by using maceration, heat- and ultrasound-assisted extraction (HAE and UAE). The extraction efficiency was expressed via total polyphenol content (TPC) and total flavonoid content (TFC). The statistical analysis (one-way ANOVA and full factorial design) has revealed that the optimal conditions for achieving the best polyphenols yield were particle size of 0.3 mm, 1:30 solid-to-solvent ratio and 50% ethanol, as environmentally friendly extraction medium, while extraction time has not shown statistically significant influence on polyphenols concentration, in all procedures. Under these conditions, the measured TPC was 26.6 mg GAE/L in maceration, 29.8 mg GAE/L in HAE and 32.7 mg GAE/L in UAE, which was in agreement with the predicted values, while TFC was 143 mg CE/L, 12.4 mg CE/L and 16.7 mg CE/L for maceration, HAE and UAE, respectively. According to total polyphenols yield, the efficiency of the extraction methods for all variables was ranked by significance in the following order: UAE > HAE > maceration, whereas total flavonoids yield was the highest in UAE, although there was no statistically significant difference between maceration and HAE. According to our results, UAE could be selected as the most successful and suitable technique for extraction of bioactive polyphenolic compounds from Serpylli herba. Using LC/MS and HPLC analysis, 9 polyphenolic compounds were identified and quantified: 6,8-Di-C-glucosylapigenin, chlorogenic acid, 6-hydroxyluteolin 7-O-glucoside, caffeic acid, luteolin 7-O-glucuronide, apigenin glucuronide, salvianolic acid g isomer, rosmarinic acid and salvianolic acid I. This study was an initial step in production of polyphenols-rich wild thyme extracts aimed to be used for formulation of foodstuffs and medicines.

AB  - The interactions of model system with pi-bonds are important and have been studied with interest. Presence of pi-bonds can affect the properties and behavior of various systems and processes. For example, fatty acids, which contain molecules with pi-bonds, and have a significant role in living organisms and influence human health.
Previous study performed calculations for different interactions of cis- and trans-unsaturated molecules. We used three groups of non-covalent interactions: (1) interactions of cis- and trans-2-butene dimers, (2) interactions between 2-butene and butane, and (3) interactions of butane dimers. SAPT decomposition analysis of interaction energies showed some different nature between the three groups of the studied model systems. Hence, one can assume that different methods should be used to study these three groups of systems. This study is based on detailed benchmark study using MP2 and large number of DFT-D methods, with various basis sets.
In benchmark study eleven methods: MP2, BLYP-D3, BP86-D3, M05-D3, M052X-D3, M06-D3, M06HF-D3, TPSS-D3, PBE1PBE-D3, B3LYP-D3 and B2PLYP-D3 and four basis sets: cc-pVDZ, cc-pVTZ, aug-cc-pVDZ and 6-311++G** for each of the method have been analyzed. The results obtained with these methods were compared with high level accurate CCSD(T) method at complete basis set (CBS) approximation.
The geometries used for calculations have been studied in all possible parallel and displaced parallel interactions. All calculations on interaction energies have been performed in Gaussian 09 (version D.01). RMTD values represent the results that have the best agreement with CCSD (T)/CBS values. As it was expected, different set of method with basis set for each of the model systems groups showed the best agreement with CCSD (T)/CBS values. For (1) interactions of 2-butene the best agreement showed method B3LYP-D3/cc - pVTZ with RMTD value of 0.0318, for (2) interactions between 2-butene and butane the best method was B2PLYP-D3/cc-pVTZ with value or RMTD 0.0293, and (3) interactions of butane dimers the best agreement has B2PLYP-D3/6-311++G** method with RMTD value of 0.0734. These results show which methods should be used to study systems with double and single bonds.

AB  - Handkea utriformis (HU), H. excipuliformis (HE) and Vascellum pratense (VP) mature fruiting bodies methanol extracts were tested for biological activities and active compounds. The extracts showed prominent radical scavenging, reducing, antioxidative and chelating abilities. Scavenging ability was correlated with phenolic (ABTS assay) or phenolic and/or sugar/beta-glucan content (DPPH). Antioxidative and Fe3+-reducing ability of VP extract was the highest, and was best correlated with flavonoid content. The same extract exhibited the best angiotensin-converting enzyme inhibitory activity. HU and HE showed selectivity toward tumor cell lines in cytotoxicity analysis. The extracts exhibited various antimicrobial activity, the best being against Listeria monocytogenes (HE, MIC-0.625 mg/mL); fatty acid content was particularly high in HU (37.25 mg/g), with linoleic acid making up more than 57% in all samples. Phenolics were present in considerable amount, as well as beta-glucans (HU, 16.67%). Although these mushrooms are inedible after autolysis process, they were still a good source of biologically active products.

AB  - Influences of the vinyl modified nanosilica Aerosil (R) 380, i.e., vinyl and methacryloyl silane coupling agent and linseed oil fatty acids (BD) reactive residues, on the mechanical properties of the unsaturated polyester resins (UPes) based nanocomposites, was studied. The polycondensation of maleic anhydride and products of poly(ethylene terephthalate) (PET) depolymerization with propylene glycol, with and without separation of ethylene glycol, yields UPe1 and UPe2 resin, respectively. The hydroxyl terminated PET depolymerization products (glycolyzates) and UPes were characterized by acid and hydroxyl values, Fourier Transform Infrared (FTIR) and nuclear magneti resonance (NMR) spectroscopies. Transmission electron microscopy (TEM) confirmed that silica nanoparticles formed domains of aggregates in the polymer matrix. An increase from 195 to 247% of stress at break (sigma(b)), and from 109 to 131% of impact strength (sigma(i)) of UPes based nanocomposites was obtained for 1 wt% addition of vinyl modified silica. Flexural strength (sigma(f)) increase from 106 to 156% for both UPes based nanocomposites with 1 wt% addition of BD modified silica. Cross-linking density (nu), storage modulus (G'), tan delta and T-g of the nanocomposite were determined from the dynamic mechanical testing and discussed in relation to the structure of silica modification.

AB  - Noncovalent interactions of cis- and trans-2-butene, as the smallest model systems of molecules with cis and trans double bonds, were studied to find potential differences in interactions of these molecules. The study was performed using quantum chemical methods including very accurate CCSD(T)/CBS method. We studied parallel and displaced parallel interactions in 2-butene dimers, in butane dimers, and between 2-butene and saturated butane. The results show the trend that interactions of 2-butene with butane are the strongest, followed by interactions in butane dimers, whereas the interaction in 2-butene dimers are the weakest. The strongest calculated interaction energy is between trans-2-butene and butane, with a CCSD(T)/CBS energy of -2.80kcalmol(-1). Interactions in cis-2-butene dimers are stronger than interactions in trans-2-butene dimers. Interestingly, some of the interactions involving 2-butene are as strong as interactions in a benzene dimer. These insights into interactions of cis- and trans-2-butene can improve understanding of the properties and processes that involve molecules with cis and trans double bonds, such as fatty acids and polymers.

AB  - In this study, calcium alginate beads immobilizing D-limonene (solid systems) have been manufactured starting from emulsions of this flavor in sodium alginate (liquid systems). The effects of alginate concentration (0.02 and 0.03 g/mL) and flavor content (5 and 10 % w/w) on viscosity, conductivity and stability of emulsions were investigated. The flavor droplets in emulsions are bigger as polymer solution is more concentrated and contains more of the flavor. When emulsions have been subjected to electrostatic extrusion and upon Na+-Ca2+ ion exchange, smaller (similar to 960 to similar to 1450 mm) and less spherical beads were obtained (sphericity factor 0.003-0.21) compared to beads produced by simple dripping technique (without electrostatic field). When wet beads were air dried, they shrunk less if they had higher content of the flavor. Novel mathematical model describing swelling kinetics of dried beads is developed. In this work, D-limonene was efficiently immobilized within Ca-alginate beads (immobilization efficiency similar to 50 to similar to 77%) and its thermal stability was confirmed by TG/MS analysis.

AB  - The aim of this paper is to obtain microbeads of natural polymers such as alginate and chitosan. These microbeads were used as potential carriers for the active ingredients so that in this study the diffusion of various substances from them is analyzed. Alginate microbeads were obtained by electrostatic droplet method. In the resulting microbeads was performed absorption of three tracer indicators with different molecular weight (acridine orange, blue dextran, methylene blue). The goal of the experiment is to monitor indicators release kinetics from microbeads. Based on these measurements the layoffs curve should give an answer on the impact of the molecular size of the three indicators on the diffusion rate of microbeads. In order to achieve the slow release of indicators alginate microbeads were coated with chitosan. Chitosan has an impact on reducing the porosity of gel, which further led to lower release tracer indicators of microbeads. Comparative analysis of the obtained layoffs curves answers about the impact on the process of obtaining micro diffusion rate indicator.
AB  - U ovom radu je prikazan proces sinteze mikročestica od prirodnih polimera, alginata i hitozana, kao i neka njihova svojstva. Osnovna primena ovih mikročestica je da se koriste kao potencijalni nosači za aktivne supstance. U tom smislu je ispitivana i difuzija različitih supstanci iz njih. Na alginatne mikročestice dobijene metodom elektrostatičke ekstruzije vršena je apsorpcija tri trejserska indikatora sa različitim molekulskim masama: akridin oranž, plavi dekstran i metilensko plavo. Praćenjem kinetike otpuštanja indikatora iz mikročestica konstruisane su krive otpuštanja koje daju informaciju o uticaju veličine molekula svakog od indikatora na brzinu difuzije iz mikročestica. Da bi se postiglo što sporije otpuštanje indikatora alginatne mikročestice su oblagane hitozanom. Hitozan ima uticaj na smanjenje poroznosti gela, što dovodi do sporijeg otpuštanja trejsersikh indikatora iz mikročestica. Uporedna analiza dobijenih krivih otpuštanja daje odgovor o uticaju postupka dobijanja mikročestica na brzinu difuzije indikatora.

AB  - In this study, calcium alginate beads immobilizing D-limonene (solid systems) have been manufactured starting from emulsions of this flavor in sodium alginate (liquid systems). The effects of alginate concentration (0.02 and 0.03 g/mL) and flavor content (5 and 10 % w/w) on viscosity, conductivity and stability of emulsions were investigated. The flavor droplets in emulsions are bigger as polymer solution is more concentrated and contains more of the flavor. When emulsions have been subjected to electrostatic extrusion and upon Na+-Ca2+ ion exchange, smaller (similar to 960 to similar to 1450 mm) and less spherical beads were obtained (sphericity factor 0.003-0.21) compared to beads produced by simple dripping technique (without electrostatic field). When wet beads were air dried, they shrunk less if they had higher content of the flavor. Novel mathematical model describing swelling kinetics of dried beads is developed. In this work, D-limonene was efficiently immobilized within Ca-alginate beads (immobilization efficiency similar to 50 to similar to 77%) and its thermal stability was confirmed by TG/MS analysis.

AB  - In production of cigarettes a lot of tobacco waste, with nicotine, goes into the environment. Hence, there is a need for an economic and efficient method to diminish the discharge of hazardous materials from tobacco wastewaters. Bioaugmentation using specialized bacteria strains could improve the efficiency of tobacco wastewater treatment. In this review paper we present bioaugmentation methods for tobacco wastewater treatment that were published in last few years. Bioaugmentation systems have proven to be very effective in removal of nicotine and TOC; it was shown that Pseudomonas sp. HF-1 and TW bacteria strains can be successfully used in reactors. Recent studies showed that controlling pH in the reactors can improve reactor performance in removing nicotine and TOC from tobacco wastewater.

AB  - Novel soy alkyd-based nanocomposites (NCs) were prepared using TiO2 nanoparticles (NPs) surface modified with different gallates, and for the first time with imine obtained from 3,4-dihydroxybenzaldehyde and oleylamine (DHBAOA). Unmodified and surface modified anatase TiO2 NPs were characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and ultraviolet-visible (UV-Vis) spectroscopy, while the amount of adsorbed ligands was calculated from thermogravimetric analysis (TGA) results. Surface modification of TiO2 NPs was confirmed by FTIR and UV-Vis spectra. The influence of the TiO2 surface modification on the dispersion of TiO2 NPs in alkyd resin, thermal, barrier and mechanical properties and chemical resistance of alkyd resin/TiO2 NC coatings was investigated. The obtained results revealed that glass transition temperature of all investigated NCs is lower than for pure resin, that the presence of TiO2 NPs surface modified with gallates had no significant influence on the thermooxidative stability of alkyd resin, while TiO2-DHBAOA NPs slightly improved alkyd resin thermooxidative stability. Also, the presence of surface modified TiO2 NPs improved barrier properties, increased stress and strain at break and hardness and chemical resistance and decreased modulus of elasticity and abrasion resistance of alkyd resin.

AB  - A full three level factorial design was implemented for optimization of extraction parameters in order to maximize total phenolic (TP) yield from stinging nettle leaf. Factors considered were percentage of methanol in solvent (X-1 : 50-100% methanol) and extraction time (X-2: 30-90 min), and maceration was used as extraction method. A second-order polynomial model was applied for fitting experimental data and predicting the response, and this mathematical model produced a satisfactory fit (R-2 = 0.993,p LT 0.01). The optimal extraction conditions were 54% aqueous methanol and 38 min extraction time, while maximal theoretical TP yield was 8.9 mg GAE/g DW. Solvent composition significantly affected extraction efficiency causing decrease of TP yield with increase of methanol percentage. On the other hand, extraction time did not influence significantly efficiency of extraction. Using LC/MS and HPLC analysis we detected and quantified three most abundant phenolic compounds: 2-O-caffeoyl malic acid, chlorogenic acid, and rutin. Comparison between maceration and ultrasound-assisted extraction (UAE) obtained extracts based on TP content as well as antiradical activity and HPLC results, showed that UAE have a better extraction capability affecting yield and time of extraction. Of all tested extracts, 54% aqueous methanolic extracts obtained with UAE and 38 min extraction time had the highest TP content.
