Estimation of fractal representation of wind speed fluctuation by artificial neural network with different training algorothms
(Elsevier, 2017)
Since the wind speed fluctuation could cause large instability in wind energy systems it is crucial to develop a method for precise estimation of the wind speed fluctuation. Fractal interpolation of the wind speed could ...
The gadolinium effect on crystallization behavior and luminescence of β-NaYF4:Yb,Er phase
(Wiley, 2019)
Single phase β-NaY0.8-xGdxYb0.18Er0.02F4 nanoparticles with different concentrations of gadolinium ions were prepared via PVP-assisted solvothermal treating at 200°C (PVP- polyvinylpyrrolidone). With the increase in Gd3+ ...
Choline chloride-based deep eutectic solvents in CaO-catalyzed ethanolysis of expired sunflower oil
(Journal of Molecular Liquids, 2018)
Choline chloride (ChCl)-based deep eutectic solvents (DESs) with different amides or polyols as hydrogen bond donors were tested as cosolvents in the ethanolysis of expired sunflower oil catalyzed by either calcined or ...
Development of lyophilized spherical particles of poly(epsilon-caprolactone) and examination of their morphology, cytocompatibility and influence on the formation of reactive oxygen species
(Paris : Association de pharmacie galenique industrielle, 2014)
A common limitation of using polymeric micro- and nanoparticles in long-term conservation is due to their poor physical and chemical stability. Freeze-drying is one of the most convenient methods that enable further ...
Hydroxyapatite nanopowders prepared in the presence of zirconium ions
(Elsevier, 2014)
Hydroxyapatite nanopowders were prepared in the presence of different concentrations of zirconium ions. Such crystallization conditions yielded significantly reduced particle size and increased specific surface area. Cell ...
Effects of different mechanical treatments on structural changes of lignocellulosic waste biomass and subsequent Cu(II) removal kinetics
(Elsevier, 2016)
In this paper, the character of structural changes induced by different mechanical treatments to Prunus persica stones (PSs), and its subsequent effect on biosorption kinetics of Cu(II) were investigated. PSs were processed ...
Inert atmosphere processing of hydroxyapatite in the presence of lithium iron phosphate
(Journal of the European Ceramic Society, 2018)
The present study describes sintering behaviour of hydroxyapatite (HAp) upon addition of lithium iron phosphate (LFP) (1-10 wt.%) system in inert (Ar) atmosphere. The interaction between materials and melting of LFP ...
Dry-pressed anodized titania nanotube/CH3NH3PbI3 single crystal heterojunctions: The beneficial role of N doping
(Elsevier, 2019)
Highly ordered, anodically grown TiO 2 nanotubes on titanium supports were annealed in ammonia atmosphere in order to incorporate nitrogen doping (≤2 at.%) in the titanium oxide lattice. FESEM micrographs revealed nanotubes ...
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 ...
Preparation of LiFePO4/C composites by co-precipitation in molten stearic acid
(Journal of Power Sources, 2011)
The olivine type LiFePO4 is synthesized via a simple and inexpensive route by aqueous co-precipitation of an Fe(II) precursor material in molten stearic acid and subsequent heat treatment at different temperatures. Stearic ...
