The effects of ionizing radiation on the structure and antioxidative and metal-binding capacity of the cell wall of microalga Chlorella sorokiniana
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
The impact of ionizing radiation on microorganisms such as microalgae is a topic of increasing importance for understanding the dynamics of aquatic ecosystems in response to environmental radiation, and for the development ...
Ultra-thin layers of iridium electrodeposited on Ti2AlC support as cost effective catalysts for hydrogen production by water electrolysis
(Elsevier Science Sa, Lausanne, 2020)
The hydrogen evolution reaction (HER) was investigated in 0.5 M H2SO4 at thin iridium layers electrodeposited on Ti2AlC substrate. Five samples, varying in thickness from 4.5 nm to 255 nm, were electrodeposited from the ...
Comparative study of lignocellulosic biomass and its components as electrode modifiers for detection of lead and copper ions
(Elsevier Science Sa, Lausanne, 2020)
Cellulose, xylan and lignin, as well as maize cell wall, were used as modifiers of carbon paste electrode. Comparative analysis of electrochemical performance of each modifier toward heavy metal detection was performed. A ...
Slow 0.1 Hz Breathing and Body Posture Induced Perturbations of RRI and Respiratory Signal Complexity and Cardiorespiratory Coupling
(Frontiers Media Sa, Lausanne, 2020)
Objective: We explored the physiological background of the non-linear operating mode of cardiorespiratory oscillators as the fundamental question of cardiorespiratory homeodynamics and as a prerequisite for the understanding ...
Leaf Soluble Sugars and Free Amino Acids as Important Components of Abscisic Acid-Mediated Drought Response in Tomato
(MDPI, Basel, 2020)
Water deficit has a global impact on plant growth and crop yield. Climate changes are going to increase the intensity, duration and frequency of severe droughts, particularly in southern and south-eastern Europe, elevating ...
Fabrication and characterization of luminescent Pr3+ doped fluorapatite nanocrystals as bioimaging contrast agents
(Amsterdam : Elsevier, 2020)
Fluorapatite doped with rare-earth elements has a wide-range of biomedical applications. Here, a new type of fluorapatite nanocrystals doped with praseodymium (FAP-Pr) with excitation-emission profiles in visible part of ...
Permanent disposal of Cs ions in the form of dense pollucite ceramics having low thermal expansion coefficient
(Korean Nuclear Soc, Daejeon, 2020)
A promising method for removal of Cs ions from water and their incorporation into stable crystal structure ready for safe and permanent disposal was described. Cs-exchanged X zeolite was hot-pressed at temperature ranging ...
Biochemical and histological characterization of succulent plant Tacitus bellus response to Fusarium verticillioides infection in vitro
(Elsevier Gmbh, Munich, 2020)
We present changes in Tacitus bellus antioxidative system that specifically correspond to subsequent phases of hemibiotroph Fusarium verticillioides infection revealed by histological analysis. T. bellus response to spore ...
Ferrous iron binding to epinephrine promotes the oxidation of iron and impedes activation of adrenergic receptors
(Elsevier Science Inc, New York, 2020)
Upon release in response to stress, epinephrine (Epi) may interact with labile iron pool in human plasma with potentially important (patho)physiological consequences. We have shown that Epi and Fe3+ build stable 1:1 high-spin ...
Effect of encapsulated lemongrass (Cymbopogon citratus L.) essential oil against potato tuber moth Phthorimaea operculella
(Elsevier Sci Ltd, Oxford, 2020)
The study reported the development of biodegradable, environment- and eco-friendly material based on natural polymers and lemongrass (Cymbopogon citratus L.) essential oil (LEO) for application as a green pesticide. The ...
