Synthesis, densification and characterization of Ag doped ceria nanopowders
(Journal of the European Ceramic Society, 2020)
Nanosized Ag-doped ceria (Ce1-xAlxO2-δ)powders (0.1 ≤ x ≤ 0.04) were obtained by self-propagating room temperature reaction. The solid solubility of Ag into ceria lattice was the highest reported so far. X-ray diffraction ...
Mathematical modelling and optimisation of lignite and wheat straw co-combustion in 350 MWe boiler furnace
(Applied Energy, 2020)
In this paper pulverised lignite-fired 350 MWe boiler furnace is selected for numerical simulations performed by using in-house developed computer code to deepen understanding of complex processes during direct co-firing ...
Single‐Crystal Red Phosphors: Enhanced Optical Efficiency and Improved Chemical Stability for wLEDs
(Advanced Optical Materials, 2020)
Crystal phosphors have many unique advantages compared with powdery ones. Herein, room-temperature-grown millimeter-sized single-crystal phosphors of Cs2XF6:Mn4+ (X = Ge, Si, and Ti) with remarkably higher external quantum ...
Comparison of fine particulate matter level, chemical content and oxidative potential derived from two dissimilar urban environments
(Science of the Total Environment, 2020)
Urban airborne particles contain a wide spectrum of components, known to have harmful effects on human health. This study reports a detailed investigation of fine particulate matter (PM2.5), chemical content and oxidative ...
Surface-induced reversal of a phase transformation for the synthesis of ε-Fe2O3 nanoparticles with high coercivity
(Acta Materialia, 2020)
A metastable ε-polymorph of iron(III) oxide (ε-Fe2O3) is a very attractive material from the technological, engineering, and scientific points of view. In comparison with other iron oxides, it is characterized by unusual ...
Low total electron yield graphene coatings produced by electrophoretic deposition
(Applied Surface Science, 2020)
Stainless steel and copper technical substrates have been coated by free standing graphene using electrophoretic deposition technique, with the final goal to obtain chemically inert low secondary electron emission surfaces. ...
Activity concentrations of 137Cs, 40K, and 210Pb radionuclides in selected medicinal herbs from Central Serbia and their effective dose due to ingestion
(Science of The Total Environment, 2020)
Specific activity of 137Cs, 40K, and 210Pb radionuclides in fifteen selected medicinal herbs from three locations in Central Serbia (two mountains, Kopaonik and Zlatar, and a valley, Sokobanja) was measured using two ...
Structural and morphological characterization of iron-doped sol-gel derived mullite powders
(Ceramics International, 2020)
The structural and morphological properties of iron-doped mullite powders are the subject of the present study. The powders of undoped and iron-doped mullite in the composition range of 3–15 wt% Fe2O3 were synthesized by ...
Synthesis and characterization of pyrochlore lanthanide (Pr, Sm) zirconate ceramics
(Journal of the European Ceramic Society, 2020)
Three different lanthanide zirconate powders: Pr2Zr2O7, Sm2Zr2O7 and PrSmZr2O7 were prepared by combustion synthesis. The synthesis initially yielded amorphous powders, which crystallized after subsequent thermal treatment. ...
New application method of the zonal model for simulations of pulverized coal-fired furnaces based on correction of total exchange areas
(International Journal of Heat and Mass Transfer, 2020)
New application method of the zonal model in numerical simulations of pulverized coal-fired furnaces, continual corrections of the total exchange areas (CCTEA), is presented. The method is based on the corrections of the ...
