Synthesis of CaOSiO2 compounds and their testing as heterogeneous catalysts for transesterification of sunflower oil
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
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
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
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
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 ...
Plasmon enhanced luminescence in hierarchically structured Ag@ (Y0.95Eu0.05)2O3 nanocomposites synthesized by ultrasonic spray pyrolysis
Ag@ (Y0.95 Eu0.05)2O3 nanocomposites were synthesized by single step Ultrasonic Spray Pyrolysis (USP). 800 °C synthesis temperature and 1.5 l/ min air flow were determined as optimal USP parameters. A detailed parametric ...
PEG and PVP assisted solvothermal synthesis of NaYF4:Yb3+/Er3+ up-conversion nanoparticles
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
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 ...
