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. ...
Integer Codes Correcting Double Errors and Triple-Adjacent Errors Within a Byte
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
This article presents a class of integer codes that are suitable for use in optical computer networks in which the data are transmitted serially. The presented codes are constructed with the help of a computer and have ...
Up-converting nanoparticles synthesis using hydroxyl-carboxyl chelating agents: Fluoride source effect
(American Institute of Physics, 2020)
The synthesis of lanthanide doped up-converting nanoparticles (UCNPs), whose morphological, structural, and luminescence properties are well suited for applications in optoelectronics, forensics, security, or biomedicine, ...
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 ...
The fractal nature as new frontier in microstructural characterization and relativization of scale sizes within space
(World Scientific, 2020)
Today in the age of advanced ceramic civilization, there are a variety of applications for modern ceramics materials with specific properties. Our up-to date research recognizes that ceramics have a fractal configuration ...
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 ...
Modification of TiO2 and ZnO Particles Under Mechanical Stress with Polypropylene
(Springer Netherlands, 2020)
Solid-state process of introducing oxygen vacancies into the structure of TiO2 and ZnO particles was studied. The phase transformations of metal oxides throughout the process were examined by X-ray diffraction (XRD). The ...
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 ...
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 ...
