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 ...
Pectin-based nanocomposite aerogels for potential insulated food packaging application
(Carbohydrate Polymers, 2018)
Environmental-friendly pectin-TiO2 nanocomposite aerogels were prepared via sol-gel process and subsequent drying under supercritical conditions. The first step includes dissolution of pectin in water, addition of proper ...
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 ...
