(Academic Press Inc Elsevier Science, San Diego, 2013)
Glucose oxidase (GOx) catalyzes the oxidation of glucose to form gluconic acid and hydrogen peroxide, a reaction with important applications in food preservation, the manufacture of cosmetics and pharmaceuticals, and the ...
First record of a hybrid striped bass (Morone saxatilisxMorone chrysops) in the Danube River
(Wiley-Blackwell, Hoboken, 2013)
Decomposition of Complex Fluorescence Spectra Containing Components with Close Emission Maxima Positions and Similar Quantum Yields. Application to Fluorescence Spectra of Proteins
(Springer/Plenum Publishers, New York, 2013)
Despite of widely application of multivariate analysis in chemometrics, problem of resolving closely positioned components in the fluorescence spectra remained unsolved, thus limiting the usage of fluorescence spectroscopy ...
Fluorescence lifetime imaging of lignin autofluorescence in normal and compression wood
(Wiley-Blackwell, Hoboken, 2013)
Wood cell walls fluoresce as a result of UV and visible light excitation due to the presence of lignin. Fluorescence spectroscopy has revealed characteristic spectral differences in various wood types, notably normal and ...
A universal fluid cell for the imaging of biological specimens in the atomic force microscope
(Wiley-Blackwell, Hoboken, 2013)
Recently, atomic force microscope (AFM) manufacturers have begun producing instruments specifically designed to image biological specimens. In most instances, they are integrated with an inverted optical microscope, which ...
SYNTHESIS PROCEDURE AND PROPERTIES OF NiFe2O4 – BaTiO3 COMPOSITES
(Institute for Multidisciplinary Research, University of Belgrade Kneza Višeslava 1, 11000 Belgrade, Serbia, 2013)
NiFe2O4 (NF) powder was prepared by auto combustion method starting from nickel and iron nitrates. After the process of self-ignition, fine precursor powder was thermally treated and forming the nickel ferrite powder. XRD ...
La-doped and La/Mn-co-doped Barium Titanate Ceramics
(Acta Physica Polonica A, 2013)
Barium titanate ceramics doped with 0.3 mol.% lanthanum and co-doped with 0.3 mol.% lanthanum and 0.05 mol.% manganese were investigated. The powders were prepared by a modified polymeric precursor method based on the ...
Profiling antioxidant activity of two primocane fruiting red raspberry cultivars (Autumn bliss and Polka)
(Academic Press Inc Elsevier Science, San Diego, 2013)
Fruit extracts of two raspberry (Rubus idaeus L) cultivars (Autumn Bliss and Polka) were analysed for total phenolic (TPC) and anthocyanin (TACY) content. Correlation of TPC with total antioxidant capacity (TAC) showed ...
The interactions of vanadium with Phycomyces blakesleeanus mycelium: enzymatic reduction, transport and metabolic effects
(Elsevier Science Bv, Amsterdam, 2013)
The biological and chemical basis of vanadium action and transport in fungi is relatively poorly understood. In this study we investigated the interactions of vanadium in physiologically-relevant redox states: vanadate ...
