Predicting effects of air staging application on existing coal-fired power steam boiler
(Applied Thermal Engineering, 2019)
The results of an extended research performed with the aim of investigating influence air staging application on processes occurred in boiler furnace have been presented in this paper. This subject was developed as a result ...
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, ...
The Genomic Impact of European Colonization of the Americas
(Current Biology, 2019)
The complexity of the admixture dynamics that shaped American populations is unveiled by Ongaro et al., where genetic data for more than 12,000 individuals from the continents are investigated. This study evaluates the ...
High harmonic generation and the billiards
(Chaos, Solitons and Fractals, 2019)
The problem of underlying classical dynamics chaotic and regular in quantum and classical billiards and their influence on high-order harmonic generation are investigated. The results concerning the Bunimovich stadium and ...
Full-scale CFD investigation of gas-particle flow, interactions and combustion in tangentially fired pulverized coal furnace
(Energy, 2019)
Investigations suggest the need for better understanding of reactive gas-particle turbulent flow phenomena in full-scale energy systems. Numerical study was done in 350 MWe utility boiler tangentially fired furnace to ...
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 ...
The effect of ceria and zirconia nanoparticles on the corrosion behaviour of cataphoretic epoxy coatings on AA6060 alloy
(Progress in Organic Coatings, 2019)
In this work an attempt was made to produce epoxy coating doped with ceria (CeO2) and/or zirconia (ZrO2) nanoparticles, in single step electrophoretric deposition process. Deposition was carried out on AA6060 cataforetically ...
