The assessment of spontaneous ignition potential of coals using TGA–DTG technique
(Combustion and Flame, 2020)
During the utilization of coal in large power plants, one of the major logistical issues is related to spontaneous ignition of the coal. This characteristic of coal depends on the rank and type of the coal, the content of ...
Study of chitosan/xanthan gum polyelectrolyte complexes formation, solid state and influence on ibuprofen release kinetics
(International Journal of Biological Macromolecules, 2020)
This study investigated the combined influence of pH adjusting agent type (hydrochloric, acetic or lactic acid) and initial pH value (3.6, 4.6, and 5.6) on formation of biocompatible chitosan/xanthan polyelectrolyte complexes ...
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 ...
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. ...
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 ...
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 ...
Effect of Fe3+ ion doping on photocatalytic ability of nanozirconia ceramic to degrade 2, 4, 6- trichlorophenol
(Ceramics International, 2020)
Pure and a series of Fe3+ doped zirconia nanopowders were synthesized combining colloidal chemistry and solvothermal method from organometallic precursors in order to correlate doping and properties of zirconia matrix. ...
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 ...
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 ...
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 ...
