Effect of four lichen acids isolated from Hypogymnia physodes on viability of rat thymocytes
(Oxford : Pergamon-Elsevier Science Ltd, 2013)
Four lichen acids, physodalic acid (F1), physodic acid (F2), 3-hydroxyphysodic acid (F3), and isophysodic acid (F4), were isolated from Hypogymnia physodes methanol extract using preparative reversed-phase high performance ...
Characterization and electrochemical properties of organomodified and corresponding derived carbonized clay
(Oxford : Pergamon-Elsevier Science Ltd, 2019)
Series of alkylammonium modified smectites with different alkylammoinum/clay ratios was synthesized (H series). The obtained organoclays were used as precursors for carbon-clay composite materials (C series). Both set of ...
Brachybacterium sp CH-KOV3 isolated from an oil-polluted environment-a new producer of levan
(Elsevier, 2017)
Various microorganisms isolated from polluted environments, such as Pseudomonas sp. and Micrococcus sp. can synthesize exopolysaccharides (EPSs) which are natural, non-toxic and biodegradable polymers. EPSs play a key role ...
Fruit as a substrate for a wine: A case study of selected berry and drupe fruit wines
(Elsevier, 2019)
This study aimed to estimate the potential of the selected berry (strawberry) and drupe (apricot, plum and sweet cherry) fruits as the substrates for the production of new fruit wines enriched with phenolic compounds. Sweet ...
Electrodeposited AgPd alloy coatings as efficient catalysts for the ethanol oxidation reaction
(Oxford : Pergamon-Elsevier Science Ltd, 2018)
The Pd and three AgPd alloy layers (AgPd1, AgPd2 and AgPd3) were electrodeposited onto Au disc electrodes from the solution containing high concentration of chloride ions (>12 M). All coatings were investigated by scanning ...
Maximally Flat-Frequency-Response Multiple-Resonator-Based Harmonic Analysis
(Ieee-Inst Electrical Electronics Engineers Inc, Piscataway, 2017)
This paper presents an improved approach to the recently proposed multiple-resonator-based method for the harmonic analysis that has been provided in the previous papers. Previously, two inherent particular cases have been ...
Al,Fe-pillared clays in catalytic decolorization of aqueous tartrazine solutions
(Elsevier, 2012)
In this work Al,Fe-pillared clays (PILCs) were applied as heterogeneous catalysts in catalytic wet peroxide oxidation of tartrazine azo-dye in water. A series of We PILCs with different Fe3+ content were synthesized. The ...
Integer quantum Hall effect in single-layer graphene with tilted magnetic field
(Amer Inst Physics, Melville, 2013)
Analytical expression for the Hall conductivity sigma(yx) in graphene is derived in more general case, in which magnetic field is not perpendicular to the plane of the sample. The derivations were carried out using ...
Ab Initio Quantum Study of Nonadiabatic S-1-S-2 Photodynamics of s-trans-Butadiene
(American Chemical Society (ACS), 2013)
The nonadiabatic photodynamics of s-trans-butadiene in its lowest singlet excited states is studied theoretically, using a fully quantal approach. The coupled 1B(u) and 2A(g) states are considered in the calculation, ...
Mechanical and thermal properties of UV cured mixtures of linear and hyperbranched urethane acrylates
(Elsevier Science Sa, Lausanne, 2012)
The properties of urethane acrylate resin mixtures based on the linear and hyperbranched aliphatic polyesters were examined. Linear polyester was synthesized from neopentil glycol and adipic acid. Hyperbranched polyester ...
