Formation kinetics and cation inversion in mechanically activated MgAl2O4 spinel ceramics
(Springer, 2020)
Solid-state mechanical activation of MgO and α-Al2O3 powders was used to produce MgAl2O4. The cation site occupancy in the resulting MgAl2O4 spinel was investigated using different methods. Differential thermal analysis ...
Stochastic measurement of wind power using a two-bit A/D converter
(Elsevier, 2020)
This paper presents a new method for stochastic measurement of wind power and energy. Compared to the existing approaches, this method has two advantages: first, it is much simpler and cheaper to implement, and second, it ...
Electrochemical and structural study on cycling performance of γ-LiV2O5 cathode
(Elsevier BV, 2021)
Electrochemical and structural properties of LiV2O5 cathode were investigated. Obtained by solid state reaction at high temperature the material crystallized as gamma polymorph phase, γ-LiV2O5. The gamma structure provides ...
Experimental study of an implantable fiber-optic microphone on human cadavers
(Elsevier BV, 2021)
In this paper, we present the results of an experimental study about a novel fiber optical vibrometer, aimed to be used as a totally implantable fiber-optic microphone for hearing aids. The sensor head, implanted inside ...
Methoxy-Substituted Hydroxychalcone Reduces Biofilm Production,Adhesion and Surface Motility of Acinetobacter baumannii byInhibiting ompA Gene Expression
(Wiley-VCH, 2021)
An increasing lack of available therapeutic options against Acinetobacter baumannii urged researchers to seek alternative ways to fight this extremely resistant nosocomial pathogen. Targeting its virulence appears to be a ...
Anodizing/Anaphoretic Electrodeposition of Nano-Calcium Phosphate/Chitosan Lactate Multifunctional Coatings on Titanium with Advanced Corrosion Resistance, Bioactivity, and Antibacterial Properties
(American Chemical Society (ACS), 2021)
The aim of this work was to investigate corrosion resistivity, bioactivity, and antibacterial activity of novel nano-amorphous calcium phosphate (ACP) potentially multifunctional composite coatings with and without chitosan ...
Properties of different types of dry electrodes for wearable smart monitoring devices
(Walter de Gruyter GmbH, 2020)
Wearable smart monitors (WSMs) applied for the estimation of electrophysiological signals are of utmost interest for a non-stressed life. WSM which records heart muscle activities could signalize timely a life-threatening ...
The gadolinium effect on crystallization behavior and luminescence of β-NaYF4:Yb,Er phase
(Wiley, 2020)
Single phase β-NaY0.8-xGdxYb0.18Er0.02F4 nanoparticles with different concentrations of gadolinium ions were prepared via PVP-assisted solvothermal treating at 200°C (PVP- polyvinylpyrrolidone). With the increase in Gd3+ ...
Valorization of walnut shell ash as a catalyst for biodiesel production
(Elsevier, 2020)
The catalytic activity of the walnut shell ash was investigated in the biodiesel production by the sunflower oil methanolysis. The catalyst was characterized by the TG-DTA, XRD, Hg porosimetry, N2 physisorption, SEM, and ...
Graph theory applied to microelectronics intergranular relations
(Taylor & Francis Group, 2021)
The focus of this study is on the control of layers between grains by applying graph theory. We performed modification of BaTiO3 nanoparticles with Y2O3. The results of capacitance change on submicron level are the part ...
