Synthesis of CaOSiO2 compounds and their testing as heterogeneous catalysts for transesterification of sunflower oil
(Elsevier, 2019)
The powder mixtures of calcium oxide (CaO) and silica gel (SiO2) in molar ratios of 1:1, 1.5:1, 2:1 and 3:1 were mechanochemically treated with the addition of water, and were subsequently calcined with a goal of synthesizing ...
Directed growth of nanoarchitected hybrid phosphor particles synthesized at low temperature
(Elsevier, 2014)
Sub-micronic particles are of considerable interest for a wide variety of applications, such as catalyst or optical ceramics, due to their unique properties determined by size, composition and structure. In this work, we ...
The processing of optically active functional hierarchical nanoparticles
(Elsevier, 2017)
Global climate changes and the aroused environmentally-energy problems categorically moved the research efforts towards programmed processing of a novel class of hierarchical materials having well defined phase, compositional ...
Effect of processing parameters on structural, morphological and optical Y2O3:Yb3+/Ho3+ powders characteristics
(Elsevier, 2014)
Rod-like and flake-like up-converting Y2O3:Yb3+/Ho3+ particles which are composed of nanoparticles with size less than 100 nm, are prepared by a simple hydrothermal processing at 473 K (3 h) followed by additional thermal ...
Aerosol route as a feasible bottom-up chemical approach for up-converting phosphor particles processing
(Elsevier, 2013)
The opportunities of the hot wall aerosol synthesis, i.e. conventional spray pyrolysis (CSP) method are demonstrated for the generation of highly spherical three-dimensional (3D) nanostructured phosphor particles with ...
PEG and PVP assisted solvothermal synthesis of NaYF4:Yb3+/Er3+ up-conversion nanoparticles
(Elsevier, 2016)
Owing to their unique optical properties, up-converting rare earth fluorides have attracted extensive attention in recent years. Varieties of synthesis procedures which generate nano- and micro-crystals with controllable ...
Atomic scale study of the dehydration/structural transformation in micro and nanostructured brucite (Mg(OH)2) particles: Influence of the hydrothermal synthesis conditions
(Elsevier, 2017)
Micro and nanostructured brucite (Mg(OH2)) particles synthesized by hydrothermal method from solutions with high content of hydrazine (0.14 M) and nitrate (0.24 g) were compared with samples obtained from low hydrazine ...
Structural and functional properties of ZnO thin films grown on Si substrates by air assisted USP method from non-aqueous solutions at low-temperature
(Advanced Powder Technology, 2017)
In this work, we deals with the processing and characterization of transparent conducting ZnO thin films on p-type Silicon substrates (1 0 0) by air assisted Ultrasonic Spray Pyrolysis (USP) method. The thin films from ...
Compositional and structural dependence of up-converting rare earth fluorides obtained through EDTA assisted hydro/solvothermal synthesis
(Elsevier, 2017)
In this feature article, we highlight our works on compositional and structural dependence of up-converting rare earth (RE) fluorides obtained through ethylenediamine tetraacetic acid (EDTA) assisted hydrothermal synthesis. ...
TEM-STEM study of europium doped gadolinium oxide nanoparticles synthesized by spray pyrolysis
(Elsevier, 2013)
Scanning-Transmission and Transmission Electron Microscopy techniques (STEM and TEM) have been applied to the characterization of nanostructured gadolinium oxides doped with europium synthesized by spray pyrolysis. The ...
