AB  - Bacterial nanocellulose (BNC) emerged as an attractive advanced biomaterial that provides desirable properties such as high strength, lightweight, tailorable surface chemistry, hydrophilicity, and biodegradability. BNC was successfully obtained from a wide range of carbon sources including sugars derived from grass biomass using Komagataeibacter medellinensis ID13488 strain with yields up to 6 g L-1 in static fermentation. Produced BNC was utilized in straightforward catalyst preparation as a solid support for two different transition metals, palladium and copper with metal loading of 20 and 3 wt%, respectively. Sustainable catalysts were applied in the synthesis of valuable fine chemicals, such as biphenyl-4-amine and 4'-fluorobiphenyl-4-amine, used in drug discovery, perfumes and dye industries with excellent product yields of up to 99%. Pd/BNC catalyst was reused 4 times and applied in two consecutive reactions, Suzuki-Miyaura cross-coupling reaction followed by hydrogenation of nitro to amino group while Cu/BNC catalyst was examined in Chan-Lam coupling reaction. Overall, the environmentally benign process of obtaining nanocellulose from biomass, followed by its utilisation as a solid support in metal-catalysed reactions and its recovery has been described. These findings reveal that BNC is a good support material, and it can be used as a support for different catalytic systems.

AB  - Kaempferol, one of the most bioactive plant flavonoids was theoretically (at M05-2X/6-311G(d,p) level of theory) investigated for its ability scavange potentially highly damaging hydroxyl and superoxide anion radicals. Theoretical calculations point to HAT and SPLET mechanisms as operative for kaempferol in all solvents under investigations.
AB  - Teoretski (na M05-2X/6-311G(d,p) nivou teorije) je ispitivana sposobnost kempferola, važnog bioaktivnog biljnog jedinjenja flavonoida, da reaguje sa potencijalno veoma štetnim hidroksi radikalom i superoksid radikal anjonom. Proračuni su pokazali da su HAT i SPLET mogući mehanizmi u svim rastvaračima.

AB  - Density functional theory calculations were performed to evaluate the antioxidant activity of alizarin red S molecule. The conformational behavior of molecule were analysed at the M06-2X/6-311++G(d,p) method. The most stable conformer of alizarin red S has two IHBs. The expected antioxidant activity of alizarin red S was justified from ionization potential (IPs) and homolytic O-H bond dissociation enthalpy (BDEs) values. Heterolytic O-H bond cleavages (proton dissociation enthalpies, PDEs) were also computed. Calculated IP, BDE, and PA values suggested that one-step H atom transfer (HAT), rather than SPLET or SET-PT, would be the most favored mechanism for explaining the antioxidant activity of alizarin red S in gas phase. In aqueous solution all of three mechanisms were competitive.
AB  - Upotrebom DFT metode vršena su izračunavanja u cilju određivanja antioksidativne aktivnosti alizarina red S. Konformaciona priroda molekula analizirana ispitana je primenom M06-2X/6-311++G(d,p) metoda. Najstabilniji konformer alizarina red S ima dve unutrašnje vodonične veze. Očekivana antioksidativna aktivnost alizarina red S određena je izračunavanjem vrednosti jonizacionih potencijala (IP) i i vrednosti entalpija homolitičkog raskidanja O-H veza (BDE). Vrednosti entalpije heterolitičkog raskidanja O-H veza (entalpije disocijacije protona, PDE), su takođe izračunate. Izračunate IP, BDE i PA vrednosti ukazuju na to da je jednostepeni transfer H-atoma (HAT), pre nego SPLET ili SET-PT mehanizam, favorizovan u pogledu antioksidativne aktivnosti alizarina red S u gasnoj fazi. U vodenom rastvoru, sva tri mehanizma su konkurentna.

AB  - In this paper are investigated the ΔHBDE, ΔHIP, and ΔHPA values of the corresponding reactions in the solvents of different polarity (water and pentylethanoate). An approach based on the enthalpies of the reactions related to the HAT, SPLET, and SET-PT mechanisms of gallic acid with some radicals (•OO-, •OH, and CH3OO•) is applied. The results show that thermodynamically favored mechanism depends on the polarity of reaction media and properties of free radical reactive species.
AB  - U ovom radu su ispitivane ΔHBDE, ΔHIP, i ΔHPA vrednosti odgovarajućih reakcija u rastvaračima različite (voda i pentiletanoat). Primenjen je pristup zasnovan na entalpijama reakcija povezanih sa HAT, SPLET, i SET-PT mehanizmima galne kiseline sa određenim radikalima (•OO-, •OH, i CH3OO•). Rezultati pokazuju da termodinamički favorizovan mehanizam zavisi od polarnosti rastvarača u kome se reakcija odvija i osobina slobodno radikalske vrste koja reaguje.

AB  - In this paper antioxidative mechanisms HAT, SPLET and SET-PT of the carboxylate anion of gallic acid (GA¯) with different radicals (OO−, OH, and CH3OO) were investigated. For this reason were examined ΔHBDE, ΔHIP and ΔHPA values of the corresponding reactions in water and pentyl ethanoate as solvents. For this purpose the M052X/6-311++G(d,p) theoretical models was applied. It was found that SET-PT is not favorable reaction path for all anions of GA (GA¯) in both solvents. On the other hand, HAT and SPLET mechanisms are competitive in all cases. Which of mentioned reaction path is predominant depends on the properties of anions, radicals and solvents.
