ZnO/ZnS (hetero)structures: ab initio investigations of polytypic behavior of mixed ZnO and ZnS compounds
(Acta Crystallographica Section B Structural Science, Crystal Engineering and Materials, 2018)
The range of feasible ZnO/ZnS polytypes has been explored, predicting alternative structural arrangements compared with previously suggested or observed structural forms of ZnO/ZnS compounds, including bulk crystal structures, ...
Microwave assisted hydrothermal synthesis of (Fe,Co) 3 O 4 nanoparticles in the presence of surfactants and effects of Co/Fe ratio on microstructure and magnetism
(Ceramics International, 2018)
Microstructure and magnetic properties of nanoparticles can be tailored by optimising the synthesis procedure and changing chemical composition. In this study, a two-step procedure, i.e., coprecipitation in the presence ...
Niobium and zinc doped titanium-tin-oxide solid-solution ceramics: Synthesis, structure and electrical characterization
(Ceramics International, 2018)
This paper describes the processing, microstructure, optical and electrical properties of the nanocrystalline (NC) niobium and zinc doped titanium-tin-oxide (TTO:NZ) based ceramics. Variety of techniques was employed (X-ray ...
Formation of needle-like and honeycomb-like magnesium oxide/hydroxide structures by electrodeposition from magnesium nitrate melts
(Electrochimica Acta, 2018)
The processes of electrochemical deposition of magnesium oxide/hydroxide on glassy carbon (GC) electrode from magnesium nitrate hexahydrate melt have been investigated. A novel procedure predicting a possibility of direct ...
Demodulated standing solitary wave and DNA-RNA transcription
(Chaos, 2018)
Nonlinear dynamics of DNA molecule at segments where DNA-RNA transcription occurs is studied. Our basic idea is that the solitary wave, moving along the chain, transforms into a demodulated one at these segments. The second ...
Influence of Fe(III) doping on the crystal structure and properties of hydrothermally prepared β-Ni(OH) 2 nanostructures
(Journal of Alloys and Compounds, 2018)
This paper systematically examines the influence of the level of Fe(III) doping on the crystal structure and other properties of Ni(OH)(2). Reference beta-Ni(OH)(2) and Fe-doped Ni(OH)(2) samples were synthesized by ...
Multicolor-tunable emissions of YOF: Ln 3+ /Yb 3+ (Ln 3+ = Ho 3+ , Er 3+ , Tm 3+ ) nanophosphors
(Dyes and Pigments, 2018)
Color tuning of down-shifting and up-conversion emissions of YOF:Ln(3+)/Yb3+ (Ln(3+) = Er3+, Tm3+) nanophosphors is demonstrated. Nanophosphors were prepared by the modified sol-gel Pechini method and characterized by the ...
Potential Source Apportionment and Meteorological Conditions Involved in Airborne 131 I Detections in January/February 2017 in Europe
(Environmental Science and Technology, 2018)
Traces of particulate radioactive iodine (I-131) were detected in the European atmosphere in January/February 2017. Concentrations of this nuclear fission product were very low, ranging 0.1 to 10 mu Bq m(-3) except at one ...
General model of microtubules
(Nonlinear Dynamics, 2018)
In the present work, we deal with nonlinear dynamics of microtubules. A new model, describing nonlinear dynamics of microtubules, is introduced. Its advantages over two existing models are demonstrated. We show that dynamics ...
The combustion performances and thermo-oxidative degradation kinetics of plane tree seeds (PTS) (Platanus orientalis L.)
(Energy, 2018)
Combustion characteristics (reactivity and reactivity evaluation, ignition index (Di), burn-out index (Df), combustion performance index (S) and combustion stability index (RW)) and thermo-oxidative degradation kinetics ...
