Optimization of process of the honeycomb-like structure formation by the regime of reversing current (RC) in the second range
(Springer, New York, 2020)
Formation of the honeycomb-like electrodes of copper by the regime of reversing current (RC) in the second range has been investigated. Morphological and structural characteristics of this electrode type obtained by various ...
Asymmetry of Cardiac Interbeat Intervals in Heart Failure
(Institute of Electrical and Electronics Engineers Inc., 2020)
Heart rate (HR) asymmetry is a dynamic phenomenon related to the interplay of dominant regulatory mechanisms of cardiovascular system which operate over different scales of observation. The aim of this work is to examine ...
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 ...
Nanocrystalline Nickel Manganite Synthesis by Sol-Gel Combustion for Flexible Temperature Sensors
(Institute of Electrical and Electronics Engineers Inc., 2020)
Nanocrystalline nickel manganite (NiMn2O4) was obtained by sol-gel combustion using glycine as fuel, followed by calcination at 800°C. X-ray diffraction (XRD) analysis confirmed the formation of a pure cubic spinel structure ...
Central nervous system-infiltrated immune cells induce calcium increase in astrocytes via astroglial purinergic signaling
(Wiley, Hoboken, 2020)
Interaction between autoreactive immune cells and astroglia is an important part of the pathologic processes that fuel neurodegeneration in multiple sclerosis. In this inflammatory disease, immune cells enter into the ...
Physical and mechanical properties of hemp fibre reinforced alkali-activated fly ash and fly ash/slag mortars
(Elsevier Sci Ltd, Oxford, 2020)
Two alkali-activated mortars with different solid prime materials were analysed. The first mortar contained fly ash, had lower density, higher water absorption, lower compactness, lower compressive strength, similar flexural ...
Selenium activates components of iron acquisition machinery in oilseed rape roots
(Springer, Dordrecht, 2020)
Aims Beneficial elements may stimulate plant growth by favoring the availability of essential nutrients for metabolic processes. This study addresses the still unexplored question whether the beneficial action of selenium ...
Identification and first insights into the structure of chitin from the endemic freshwater demosponge Ochridaspongia rotunda (Arndt, 1937)
(Elsevier, Amsterdam, 2020)
Studies on the identification, properties and function of chitin in sponges (Porifera), which are recognized as the first multicellular organisms on Earth, continue to be of fundamental scientific interest. The occurrence ...
Anthropogenic Pressures on Watercourses of the Danube River Basin in Montenegro
(Springer, 2020)
The surface area of Montenegro’s portion of the Black Sea drainage basin is 7075 km2, or 0.9% of the entire basin, and is made up of the rivers Tara, Piva, Lim, Ćehotina and Ibar, and Lake Plav. The major polluters of ...
Liposomal integration method for assessing antioxidative activity of water insoluble compounds towards biologically relevant free radicals: example of avarol
(Taylor & Francis Ltd, Abingdon, 2020)
The liposomal integration method, in conjunction with electron paramagnetic resonance (EPR) spectroscopy, has been presented for the investigation of antioxidant activity of selected water-insoluble compound towards ...
