One-step synthesis of NIR-responsive NaYF4:Yb,Er"Chitosane nanoparticles for biomedical application
(Belgrade : Institute of Physics Belgrade, 2017)
There is a great technological interest in synthesis of lanthanide doped upconverting nanoparticles with specific morphological characteristics and efficient luminescence response suitable for biomedical use [1]. A ...
Degradation behaviour of PCL/PEO/PCL and PCL/PEO block copolymers under controlled hydrolytic, enzymatic and composting conditions
(Elsevier Sci Ltd, Oxford, 2017)
Short-term hydrolytic and enzymatic degradation of poly(epsilon-caprolactone) (PCL), one series of triblock (PCL/PEO/PCL) and the other of diblock (PCL/PEO) copolymers, with a low content of hydrophilic PEO segments is ...
Re-formation of metastable epsilon-Fe2O3 in post-annealing of Fe2O3/SiO2 nanostructure: Synthesis, computational particle shape analysis in micrographs and magnetic properties
(Ceramics International, 2017)
Several Fe2O3/SiO2 nanostructures were synthesized by the combination of the microemulsion and a sol-gel methods. Based on X-ray powder diffraction (XRD) and magnetic measurements (giant coercivity similar to 2.13 T) we ...
In-vitro visualization of primary tumor cells using up-conversion nanophosphors
(Belgrade : Serbian Ceramic Society, 2017)
For such purpose, Ln-UCNPs should have specific morphological characteristics and efficient luminescence response. In this work, a biocompatible and water dispersible NaYF4:Yb,Er"PLGA nanoparticles synthesized using a ...
Development of low calorie jams with increased content of natural dietary fibre made from tomato pomace
(Elsevier Sci Ltd, Oxford, 2017)
In this study, four jam formulations were developed, starting with the basic formulation (Jam 1) containing sucrose and without added pectin. Sucrose was partially (50%) replaced by stevioside in formulations of Jam 2 and ...
Technological analysis for machining of the reformers for fuel cells testing
(Innovation Center of Faculty of Mechanical Engineering, 2017)
Reformer is an integral component of the polymeric electrolyte membrane (PEM) fuel cell and it is used for
experimental combustion testing. By analyzing the geometry of the experimental reformer, it consists of three
plates, ...
Preparation and characterization of bismuth germanium oxide (BGO) polymer composites
(Elsevier Science Sa, Lausanne, 2017)
Bismuth germanium oxide Bi12GeO20 (BGO) has very interesting electrical, optical and magnetic properties. In order to make devices based on this material more flexible, its powder was used for preparing polymer composites. ...
Fractographic analysis of biomedical Ti-based alloys with acicular microstructures
(Ruđer Bošković Institute and Croatian Microscopy Society, 2017)
Thermal Shock Properties of Glass-ceramics Synthesized From a Glass Frit
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2017)
In this study, the behavior of glass-ceramics synthesized from a glass frit of FFW (Final Flotation Waste) originated from the RTB Bor Company was investigated. Thermal shock resistance was monitored in order to assess the ...
Structural Properties of the Multiwall Carbon Nanotubes/Poly(Methyl Methacrylate) Nanocomposites: Effect of the Multiwall Carbon Nanotubes Covalent Functionalization
(Wiley, Hoboken, 2017)
The structural characteristics of polymer nanocomposites with functionalized multiwall carbon nanotubes (MWCNTs) in poly(methyl methacrylate) matrix have been studied in relation to nanofiller loading and surface functionality. ...
