Transparent and conductive CdS:Ca thin films for optoelectronic applications
(Springer Heidelberg, 2020)
This paper presents the structural, morphological, optical and electrical evolution of Ca-doped CdS thin films. Non-doped and Ca-doped CdS samples with various amounts of Ca atoms (from 0 to 10 at.% with an increasing step ...
Effects of silver doping on magnetic levitation performance of MgB2 superconductors
(Elsevier Sci Ltd, 2020)
MgB2 bulk samples with the silver contents of 0, 1.5, 3.0, 4.5, 6.0, 9.0 and 12.0 wt% were fabricated at 775 degrees C for 3 h in Ar atmosphere by solid-state reaction method. the structural and electromagnetic properties ...
A case study on pollution and a human health risk assessment of heavy metals in agricultural soils around Sinop province, Turkey
(Pergamon-Elsevier Science Ltd, 2020)
In the present study, the concentration levels of heavy metals such as Cr, Fe, Ni, Cu, Zn, As and Pb in soil samples collected from 88 sampling locations around Sinop Province, Turkey were measured using energy dispersive ...
Quantum emitter interacting with graphene coating in the strong-coupling regime
(Amer Physical Soc, 2020)
We demonstrate the strong coupling of a quantum dot and a graphene spherical shell coating it. Our simulations are based on solutions of three-dimensional Maxwell equations, using a boundary element method approach. ...
Density functional theory investigation of oxidation intermediates on gold and gold-silver surfaces
(Amer Chemical Soc, 2020)
Gold and gold-silver alloys can be active and selective oxidation catalysts. Previous work has suggested that O-2 dissociation occurs at bimetallic step sites on gold-silver alloys, but the site responsible for the rest ...
Dynamic critical phenomena in a multilayer Ising system
(Elsevier, 2020)
Using the mixed-spin system, we precisely calculate the dynamic critical phenomena, namely dynamic compensation behaviors, dynamic phase diagrams and dynamic hysteresis loops in a multilayer Ising system that composes of ...
First-principles investigation of CO and CO2 adsorption on gamma-Al2O3 supported monoatomic and diatomic Pt clusters
(Elsevier, 2020)
Supported clusters of transition metal atoms are key components of heterogeneous catalysts. Understanding their interaction with small molecular species is therefore an important step in catalyst design. in this work, we ...
The effects of the intense laser field on the resonant tunneling properties of the symmetric triple inverse parabolic barrier double well structure
(Elsevier, 2020)
Transmission properties of an electron in the symmetric triple inverse parabolic barrier double well structure have been investigated under the intense laser field. We have found that the laser field has effects on tunneling ...
Trapped magnetic field and levitation force properties of multi-seeded YBCO superconductors with different seed distance
(Elsevier Science Sa, 2020)
The performance of large grain (RE)BCO superconducting bulks has the significant potential for magnetic-force based applications such as trapped field magnets and magnetic levitation devices. These materials can trap high ...
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 ...
