First-principles study of coupled effect of ripplocations and S-vacancies in MoS2
(Amer Inst Physics, 2019)
Recent experiments have revealed ripplocations, atomic-scale ripplelike defects on samples of MoS2 flakes. We use quantum mechanical calculations based on density functional theory to study the effect of ripplocations on ...
Enhanced efficiency of CdS/P3HT hybrid solar cells via interfacial modification
(Scientific Technical Research Council Turkey-Tubitak, 2019)
The present paper examines the effects of surface modification of CdS with diverse dyes on fabricated CdS-based hybrid solar cells. the X-ray diffraction results showed that CdS thin films had a hexagonal phase with a ...
Ab initio atomistic thermodynamics modeling of adsorption of oxygen on gold and gold-silver surfaces
(2019)
A theoretical study of oxygen adsorption on gold and gold-silver surfaces by means of density functional theory (DFT) calculations with an atomistic thermodynamic model is performed. The (111) and (211) facets of gold and ...
Determination of natural radioactivity levels and gamma radiation attenuation coefficients in propolis samples and the study of its antioxidant properties
(Walter de Gruyter Gmbh, 2020)
Thanks to its rich content, propolis has been used to protect the hive from all kinds of external influences and for disinfection by bees. Furthermore, it is an important marker for monitoring environmental pollution because ...
Impact of environmental conditions on heavy metal concentration in honey samples
(Scibulcom Ltd, 2020)
The aim of the present study is determination of heavy metals in honey samples with different botanic origin produced by Kosovo farmers and as well as the comparison of gathered results with the specific environmental ...
Characterization of Cu(In,Ga)(Te,S)(2) thin films grown on stainless steel foil substratesIo
(IOP Publishing, 2023)
In this study, Cu(In,Ga)(Te,S)(2) (CIGTS) thin films with [Ga]/([In] +/- [Ga]) atomic ratios in the ranges of 0.22-0.28 and 0.50-0.67 were fabricated using a two-stage technique. During the first stage of the technique, ...
Enhancing magnetic levitation and guidance force and weight efficiency of high-temperature superconducting maglev systems by using sliced bulk YBCO
(Wiley, 2023)
We aimed to enhance the magnetic force efficiency of Maglev systems without increasing total weight. For this aim, we divided YBCO bulks into three slices horizontally to utilize the YBCO-permanent magnetic guideway (PMG) ...
Thermal conductivity and phase-change properties of boron nitride-lead oxide nanoparticle-doped polymer nanocomposites
(MDPI, 2023)
Thermally conductive phase-change materials (PCMs) were produced using the crosslinked Poly (Styrene-block-Ethylene Glycol Di MethylMethacrylate) (PS-PEG DM) copolymer by employing boron nitride (BN)/lead oxide (PbO) ...
Dynamic hysteresis curves in a mixed spin ternary alloy system under the time-dependent magnetic field
(Institute of Physics, 2023)
The dynamic hysteresis features in mixed spins- (1/2,3/2,5/2) ternary alloy system with formula ABpC(1-p) was examined through Glauber-type stochastic dynamic and mean-field theory. The system includes two interpenetrating ...
