The influence of the starch coating on the magnetic properties of nanosized cobalt ferrites obtained by different synthetic methods
(Elsevier, 2021)
To investigate the magnetic behavior of starch-coated cobalt ferrites, well-established synthetic methods, i.e., coprecipitation, mechanochemical, ultrasonically assisted coprecipitation, microemulsion, and microwave-assisted ...
Microsized fayalite Fe2SiO4 as anode material: the structure, electrochemical properties and working mechanism
(Springer Science and Business Media LLC, 2021)
Fayalite Fe2SiO4 is synthesized by the solid-state reaction without ball milling. The obtained powder is further structurally and electrochemically examined. Field emission scanning electron microscopy (FESEM) showed that ...
Thermogravimetric insight in the reduction of xCuO – (1-x)MoO3 oxide system (0.1 ≤ x ≤ 0.9) by hydrogen
(Elsevier BV, 2021)
The oxide mixtures xCuO-(1-x) MoO3 were synthesized by gel-combustion procedure. The existence of phase mixture CuO + Cu3Mo2O9 and MoO3 + CuMoO4 in CuO-rich and MoO3 -rich composition region, respectively, were evidenced. ...
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 ...
Changes in long-term properties and natural cycles of the Danube river level and flow induced by damming
(Elsevier BV, 2021)
In this paper we assessed changes in scaling properties of the river Danube level and flow data, associated with building of Djerdap/Iron Gates hydrological power plants positioned on the border of Romania and Serbia. We ...
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 ...
Assessment of Grain Size and Grain Refinement Efficiency by Calculation of Released Heat Attributed to Formation of Primary Aluminum Crystals During Solidification of Al7Si4Cu Alloy
(Springer Science and Business Media LLC, 2021)
Assessing heat released only related to the formation of primary crystals provides results with a significantly higher sensitivity than a traditional assessment of undercooling value. In this work, two similar Ti5B1 master ...
Thermodynamic and kinetics investigation of elemental evaporation from molten Al7Si4Cu alloy
(Elsevier BV, 2021)
Treatment of liquid aluminum alloys in low vacuum conditions is often applied for parts production in the automotive and aerospace industry because of its effectiveness in removing dissolved gases. Because of the low vapour ...
Integer codes correcting single asymmetric errors
(Springer Science and Business Media LLC, 2021)
This paper presents a class of integer codes capable of correcting single asymmetric errors. The presented codes are defined over the ring of integers modulo 2b– 1 and are constructed with the help of a computer. The results ...
Methoxy‐Substituted Hydroxychalcone Reduces Biofilm Production, Adhesion and Surface Motility of Acinetobacter baumannii by Inhibiting ompA Gene Expression
(Wiley, 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 ...
