Effects of fluorination on the structure, magnetic and electrochemical properties of the P2-type NaxCoO2 powder
(Journal of Alloys and Compounds, 2019)
The main goal of this research has been to investigate for the first time the effects of fluorination on the crystal structure, magnetic, and electrochemical properties of the P2-type NaxCoO2 powder. Sodium cobalt oxide ...
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 ...
NPD in small manufacturing enterprises in Serbia
(Tehnički vjesnik, 2015)
New product development in small manufacturing enterprises on the territory of Serbia was investigated on a representative sample of micro and small enterprises covering a broad range of businesses. It was found that market ...
Fluctuations of the number of adsorbed molecules due to adsorption–desorption processes coupled with mass transfer and surface diffusion in bio/chemical MEMS sensors
(Elsevier, 2014)
In this study we have developed, for the first time, the comprehensive theoretical model of the fluctuations of the number of adsorbed molecules in MEMS chemical and biological sensors, taking into account the processes ...
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 ...
Optical characterization of a novel miniature microwave ICP plasma source in nitrogen flow
(IOP Publishing, 2018)
Abstract A Miniature Microwave (MMW) Inductively Coupled Plasma Source (ICP) is characterized by optical emission spectroscopy and by optical imaging of nitrogen plasma. The MWW source operates in two different modes (H – ...
The initial characteristics of the polypyrrole based aqueous rechargeable batteries with supercapattery characteristics
(Elsevier, 2019)
The electrochemically synthesized polypyrrole (PPy) is investigated as a possible active material of the low-cost aqueous based secondary power sources in combination with zinc, lead oxide, and lead sulfate. The discharge ...
NIR photo-driven upconversion in NaYF4:Yb,Er/PLGA particles for in vitro bioimaging of cancer cells
(Elsevier, 2018)
Lanthanide-doped fluoride up-converting nanoparticles (UCNPs) represent the new class of imaging contrast agents which hold great potential for overcoming existing problems associated with traditionally used dyes, proteins ...
Compressive strength and microstructure of ordinary cured and autoclaved cement-based composites with mechanically activated kaolins
(Elsevier, 2018)
The effects of two different mechanically activated kaolins, AKV (61% kaolinite, 14% quartz and 16% mica) and AKG (51.6% kaolinite and 40.6% quartz) on the compressive strength of cement composites and microstructure of ...
Tesla's Fountain – Modeling and simulation in ceramics technology
(Elsevier, 2018)
In this paper, we present Tesla's Fountain in ceramics technology reconstruction from basic 3D model, simulation of the engine, light and fluids till the real materialization. As the one of the most important model purposes, ...
