Guiding of protons through radially deformed triple-wall carbon nanotubes
(European Physical Journal D. Atoms, Molecules, Clusters and Optical Physics, 2021)
Abstract: Subject of this study is a theoretical investigation of the channeling of high energy protons with the radially deformed triple-wall carbon nanotubes (TWNTs). Specifically, we chose a proton energy of 1 GeV and ...
Constraining theories of gravity by fundamental plane of elliptical galaxies
(Physics of the Dark Universe, 2020)
We show that fundamental plane of elliptical galaxies can be used to obtain observational constraints on metric theories of gravity. Being it connected to global properties of ellipticals, it can fix parameters of modified ...
Characterization of PM2.5 sources in a Belgrade suburban area: a multi-scale receptor-oriented approach
(Environmental Science and Pollution Research, 2020)
Designated as the most harmful for health, PM2.5 aerosol fraction was a subject of our study. It was collected for all four seasons during 2014/15 in the suburban area of Belgrade (Serbia) and analysed for Al, Si, P, S, ...
Influence of bulk mass distribution on orbital precession of S2 star in Yukawa gravity
(European Physical Journal D. Atoms, Molecules, Clusters and Optical PhysicsEuropean Physical Journal D. Atoms, Molecules, Clusters and Optical Physics, 2021)
In this study we investigate possible applications of observed S2 orbit around Galactic Center for constraining the Yukawa gravity at scales in the range between several tens and several thousands astronomical units (AU) ...
Ferromagnetism in intermetallic Hf6Co23 alloy
(Journal of Magnetism and Magnetic Materials, 2021)
Ferromagnetism in Hf6Co23 intermetallic alloy at room temperature has been confirmed from perturbed angular correlation measurements using 181Hf probe. The strength of hyperfine magnetic field at room temperature for this ...
A novel nonenzymatic hydrogen peroxide amperometric sensor based on AgNp@GNR nanocomposites modified screen-printed carbon electrode
(Journal of Electroanalytical Chemistry, 2020)
A nonenzymatic hydrogen-peroxide sensor was developed by utilization of silver nanoparticles and graphene nanoribbons. The mentioned composite was inflicted on a screen-printed carbon electrode which provides disposable, ...
Investigation of a new way of synthesis for Nano crystallites of La2O2S & 1%Ln3+ (Ln = Pr, Eu, Tb, Dy, Er) doped La2O2S and study their structural and optical properties
(Journal of Alloys and Compounds, 2021)
Nano-crystallite Lanthanum oxysulfide (La2O2S), a versatile compound with a wide range of applications, has been synthesized by the Solid State, Hydrothermal, and a novel Furnace Combustion technique. The last one limits ...
Microstructure and Wear Behavior of MMC Coatings Deposited by Plasma Transferred Arc Welding and Thermal Flame Spraying Processes
(Transactions of the Indian Institute of Metals, 2020)
In this study, two erosion protection MMC coatings with WC particles were deposited by the plasma transferred arc (PTA) welding. One of the coatings with tungsten carbide WC in the NiBSi matrix (WC/NiBSi), and the second ...
Photoluminescence of ZrO2:Gd3+ and ZrO2:Dy3+ coatings formed by the plasma electrolytic oxidation
(Journal of Alloys and Compounds, 2020)
Zirconia (ZrO2) coatings, doped with Gd3+ and Dy3+ in various concentrations, were created by the plasma electrolytic oxidation (PEO) process of zirconium by the addition of Gd2O3 and Dy2O3 particles to the supporting ...
Study of MW-scale biogas-fed SOFC-WGS-TSA-PEMFC hybrid power technology as distributed energy system: Thermodynamic, exergetic and thermo-economic evaluation
(International Journal of Hydrogen Energy, 2021)
Advanced biogas power generation technology has been attracting attentions, which contributes to the waste disposal and the mitigation of greenhouse gas emissions. This work proposes and models a novel biogas-fed hybrid ...
