Influence of the electron donor properties of hypericin on its sensitizing ability in DSSCs
(Royal Soc Chemistry, Cambridge, 2019)
Rising demands for renewable energy sources have led to the development of dye sensitized solar cells. It is a challenge to find a good and low cost sensitizer, which has a low environmental impact. In this work, we conducted ...
Low-Energy Strawberry Fruits of Joly Cultivar, the First Step Towards a Novel, Food-Based Solution for the Obese Population
(MDPI, Basel, 2019)
This study aimed to produce low-energy strawberries of the Joly cultivar by breeding them under different growing conditions. The efficacy of such a process was screened by the means of common physico-chemical parameters ...
The conformation of epinephrine in polar solvents: an NMR study
(Springer/Plenum Publishers, New York, 2018)
Epinephrine (Epi) is a physiologically important catecholamine. Molecular conformation of Epi controls the interactions with other molecules and its biological effects. There have been a number of theoretical studies ...
Mn-Zn ferrite line EMI suppressor for power switching noise in the impulse/high current bias regime
(Tubitak Scientific & Technical Research Council Turkey, Ankara, 2018)
Ferrite cores 50 mm long were formed from large ferrite tubes obtained using fine Mn-Zn ferrite powder (M-30-IHIS) extruded and sintered at 1280 degrees C for 2 h. Core impedance was measured in the HF range (0.1-100 MHz), ...
Silicon Alleviates Iron Deficiency in Barley by Enhancing Expression of Strategy II Genes and Metal Redistribution
(Frontiers Media Sa, Lausanne, 2019)
The beneficial effects of silicon (Si) have been shown on plants using reduction-based strategy for iron (Fe) acquisition. Here we investigated the influence of Si on Fe deficiency stress alleviation in barley (Hordeum ...
Biliverdin-copper complex at physiological pH
(Royal Soc Chemistry, Cambridge, 2019)
Biliverdin (BV), a product of heme catabolism, is known to interact with transition metals, but the details of such interactions under physiological conditions are scarce. Herein, we examined coordinate/redox interactions ...
Influence of starting powder milling on structural properties, complex impedance, electrical conductivity and permeability of Mn-Zn ferrite
(Springer, Dordrecht, 2016)
In this work we have analyzed how milling starting commercial Mn-Zn powder prior to the sintering process has an influence on electrical conductivity, relative permittivity and complex impedance in the frequency range from ...
The polysaccharide extracts from the fungi Coprinus comatus and Coprinellus truncorum do exhibit AChE inhibitory activity
(Taylor & Francis Ltd, Abingdon, 2019)
The polysaccharide (PSH) extracts from the edible mushroom species Coprinus comatus and Coprinellus truncorum were screened in liquid for their acetylcholinesterase inhibitory (AChE) activity. Both extracts were found to ...
Tyramine modified alginates via periodate oxidation for peroxidase induced hydrogel formation and immobilization
(Elsevier Science Bv, Amsterdam, 2015)
Phenol and amino groups were introduced into alginate to different degrees via oxidation with 2.5, 5, 10, 15 and 20 mol% of periodate and reductive amination by tyramine. Modification of alginate with tyramine was confirmed ...
Comparison of Photoacoustic Signals in Photosynthetic and Nonphotosynthetic Leaf Tissues of Variegated Pelargonium zonale
(Springer/Plenum Publishers, New York, 2016)
Green-white variegated leaves of Pelargonium zonale were studied using the photoacoustic method. Our aim was to characterize photosynthetically active green tissue and nonphotosynthetically active white tissue by the ...
