AB  - In the last two decades, the Turija oil field (SE Pannonian Basin, Serbia) has attracted attention through oil discoveries in new wells. The source rocks of the Turija oil are still unknown. In this study, potential lower Miocene (Ottnangian-Karpatian) to upper Miocene (Pannonian) source rocks from some boreholes near the Turija oil field were investigated to determine the origin, depositional environment, hydrocarbon potential and maturity of organic matter (OM). The Rock-Eval method, biomarker and carbon isotope analyses were used. The obtained results indicate a mixed aquatic-terrestrial (Ottnangian-Karpatian and Badenian) and predominantly aquatic (Badenian and Pannonian) origin of OM, deposited under variable, reducing to oxic conditions. The majority of studied samples show a good oil generation potential. Numerous maturity indicators imply that maturity of OM varies from immature to mature. The large heterogeneity (facies and maturity) of the Badenian samples is consistent with remarkable environmental changes caused by the uplift of the Alps and Carpathians in the middle to late Badenian.

AB  - The paper describes an investigation of structural and geochemical properties of genetically similar crude oils from the Turija-sever field located in the South-Eastern Pannonian Basin, Serbia. Samples from 56 wells were examined by infrared spectroscopy (IR) and gas chromatography (GC). The IR spectral region of 2800– 3000 cm–1 was modeled by the sum of Lorentzian functions to reveal the contributions of aliphatic stretching vibrations, from which the alkane branching factor was evaluated. Being dependent on the aliphatic chain branching, the CH2 absorption peaks shifted by 3–4 cm–1 towards high frequencies when passing from the least-branched to the most-branched oil samples. This is associated with an increase in the fraction of gauche-conformations in polymethylene fragments. GC data shows the similarity of Turija-sever oils in thermal maturity, corresponding to to the early stage of liquid hydrocarbon generation and revealing a mixed aquatic-terrigenous origin of the precursor organic matter (OM) generated in a transitional reducing to weakly oxidizing depositional environment. In view of a significant correlation revealed between the alkane branching and the geochemistry, the samples were readily divided into two groups. Specifically, oils of Group I have a higher contribution of algae to the precursor OM and were generated under more reducing conditions than oils of Group II. The obtained data demonstrates in practice the advantage of the GC-IR combination to explain the structural and geochemical properties of sedimentary OM.
AB  - Целью работы являлось изучение структурно-геохимических характеристик генетически сходных нефтей месторождения Турия-север, расположенного в юго-восточной части Паннонского бассейна на территории Сербии. Методами инфракрасной спектроскопии (ИК) и газожидкостной хроматографии (ГЖХ) были исследованы образцы из 56 скважин. Моделированием области ИК-спектра 2800-3000 см-1 суммой функций Лоренца были выделены вклады валентных колебаний алифатических групп, на основании которых рассчитывалась степень разветвления алканов. Положение пиков поглощения групп CH2 зависит от разветвленности алифатических цепей, смещаясь на 3-4 см-1 в сторону высоких частот при переходе от минимальной к максимальной степени разветвления для рассматриваемой коллекции нефтей, что связано с сопутствующим увеличением доли гош-конформаций в полиметиленовых фрагментах. Согласно данным ГЖХ, нефти месторождения Турия-север близки по степени термической преобразованности, которая соответствует ранней стадии генерирования жидких углеводородов и характеризуются смешанным аквагенно-терригенным происхождением исходного органического вещества (ОВ), сформировавшегося в переходной восстановительно-слабоокислительной обстановке осадконакопления. Степень разветвления алканов показала значимую корреляцию с геохимическими параметрами, позволяя разделить образцы на две группы: нефти группы I с повышенным вкладом водорослей в исходном ОВ и сформировавшиеся в более восстановительных условиях по сравнению с группой II. Полученные результаты на практике демонстрируют преимущество сочетания методов ГЖХ и ИК-спектроскопии для выяснения структуры и геохимических особенностей осадочного ОВ.

AB  - Cellobiose dehydrogenase (CDH, EC 1.1.99.18) from white rot fungi Phanerochaete chrysosporium can be used for constructing biosensors and biofuel cells, for bleaching cotton in textile industry, and recently, the enzyme has found an important application in biomedicine as an antimicrobial and antibiofilm agent. Stability and activity of the wild-type (wt) CDH and mutants at methionine residues in the presence of hydrogen peroxide were investigated. Saturation mutagenesis libraries were made at the only methionine in heme domain M65 and two methionines M685 and M738 in the flavin domain that were closest to the active site. After screening the libraries, three mutants with increased activity and stability in the presence of peroxide were found, M65F with 70% of residual activity after 6 h of incubation in 0.3 M hydrogen peroxide, M738S with 80% of residual activity and M685Y with over 90% of residual activity compared to wild-type CDH that retained 40% of original activity. Combined mutants showed no activity. The most stable mutant M685Y with 5.8 times increased half-life in the presence of peroxide showed also 2.5 times increased kcat for lactose compared to wtCDH and could be good candidate for applications in biofuel cells and biocatalysis for lactobionic acid production.

AB  - The triplet excited-state formation efficiency in a flavin derivative was increased by the introduction of iodine into the molecular framework. The transient absorption measurements showed that the intersystem crossing rate was 1.1 X 10(10) s(-1) significantly faster than in the parent flavin compound. Furthermore, the photocatalytic efficiency of iodoflavin was evaluated using the oxidation of benzyl alcohol as a model reaction. The benzaldehyde product yields were higher when iodoflavin was used as a photocatalyst, showing that the increased triplet yield directly translates into improved photocatalysis. The iodoflavin catalyst also allowed the use of higher substrate concentrations (since the undesired electron transfer from singlet excited state was minimized), which is expected to improve the practical aspects of photocatalysis by flavins.

AB  - The triplet excited-state formation efficiency in a flavin derivative was increased by the introduction of iodine into the molecular framework. The transient absorption measurements showed that the intersystem crossing rate was 1.1 X 10(10) s(-1) significantly faster than in the parent flavin compound. Furthermore, the photocatalytic efficiency of iodoflavin was evaluated using the oxidation of benzyl alcohol as a model reaction. The benzaldehyde product yields were higher when iodoflavin was used as a photocatalyst, showing that the increased triplet yield directly translates into improved photocatalysis. The iodoflavin catalyst also allowed the use of higher substrate concentrations (since the undesired electron transfer from singlet excited state was minimized), which is expected to improve the practical aspects of photocatalysis by flavins.

AB  - We synthesized three dumbbell-like compounds 2a-c, each containing two C-60 groups at the periphery and pyromellitic diimide (PMDI) in the middle, and examined their electronic as well as assembly characteristics with both experimental and computational methods. Cyclic voltammetry (CV) measurements revealed that each of three electron-accepting (AAA) triads could accommodate up to eight electrons. Computational studies (density functional theory, DFT) of 2a-c at PBEPBE/6-311G(d, p) level of theory, with B3LYP/6-31G(d) optimized geometries, revealed that HOMO-LUMO energy gaps are similar to those of the model compound [6,6]-phenyl-C-61-butyric acid methyl ester (PCBM). Compounds 2a-c were also found to assemble into vesicles and nanoparticles on the copper grid (100-300 nm, TEM), while giving more sizeable aggregates after a deposition on the glass (SEM,  gt  5 mm). Understanding the packing of 2a-c on various solid substrates, as well as the assembly characteristics in general, is important for tuning the properties and fabrication of electronic/optical devices. On the basis of the results of conformational analysis (MM and DFT calculations), we deduced that different alkyl spacers in 2a-c ought to play a role in pi-pi interactions between the aromatic components of the triad to guide the packing and therefore morphology of the material.
