Analysis of the Influence of Competitive Adsorption and Mass Transfer on Adsorbed Mass Fluctuations in Affinity-Based Biosensors
(Elsevier, 2012)
We analyze the fluctuations of the equilibrium adsorbed mass in affinity-based biosensors, caused by both the random nature of adsorption-desorption and mass transfer processes of two molecular species (the target and the ...
Structural, electrical and magnetic properties of mechanically activated manganese and zinc ferrite
(Belgrade : Institute for Multidisciplinary Research of the University of Belgrade, 2017)
Starting hematite (Fe2O3), zinc oxide (ZnO) and manganese carbonate (MnCO3) powders were homogenized in a planetary ball mill in stainless steel bowls with stainless steel balls for 15 min, calcined in air at 1000 C for ...
Hydro/solvo-thermal synthesis of surface modified NaYF4 co-doped Yb3+/Er3+ up-conversion nanoparticles
(Belgrade : Institute of Technical Sciences of SASA, 2015)
Surface modified up-conversion rare earth fluorides have attracted attention in recent years. Owing to their unique optical properties they can be used for biomedical application such as bio-detection, fluorescene imaging ...
Kreiranje morfologije i veličine čestica ZnO prahova
(Beograd : Savez inženjera i tehničara Srbije, 2012)
U ovom tekstu objašnjeni su postupci sinteze prahova ZnO i mogućnosti da se tim sintezama morfologija i srednja veličina čestica kreiraju od mikrometarskih štapića do nanometarskih sfernih čestica. Primenjene su dve metode ...
Characterization of mechanically activated ZnO powder
(Belgrade : Serbian Ceramic Society, 2013)
Materials based on ZnO structure have more frequently application as fillers in polymer ceramics nanocompozites. Performances of these materials depends on fillers morphology, surfaces texture and particles size. According ...
One-pot synthesis of biocompatible NaYF4:Yb,Er nanoparticles for cell labeling
(Belgrade : Materials Research Society of Serbia, 2018)
In modern medical research, great attention has been focused to the development of the new biomarkers which include up-converting nanoparticles (UCNPs). Their optical response is triggered by NIR radiation that achieves ...
Properties of Magnesium Titanate Ceramic Obtained by Two Stage Sintering
(Belgrade : Serbian Ceramic Society, 2014)
The aim of this paper was investigation of structural and electrical properties of magnesium titanate ceramic obtained mechanochemically and subjected to two stage sintering process. Mixtures of MgO and TiO2 were treated ...
Partitioning and purification of cellulases in aqueous two-phase system
(Tatranské Matliare : Slovak Society of Chemical Engineering, 2012)
Aqueous two-phase systems can be formed by mixing the solutions of two mutually incompatible polymers or polymer and salt above critical concentrations and represent media that are very well suited for the separation and ...
Biodiesel synthesis and kinetic analysis based on MnCO3/Na silicate as heterogeneous catalyst
(Belgrade : Serbian Chemical Society, 2018)
Тhe MnCO3/Na silicate (Mn/Na/Si mole ratio of 4.65:1:1.65) catalyst in the form of solid particles with diameter of 0.99–1.99 mm was used as a catalyst for transesterification of soybean oil in batch autoclave at different ...
Exploring fractality of microcrystalline diamond films
(American Institute of Physics, 2018)
Diamond is renowned as a material with superlative physical qualities, most of which originate from the strong covalent bonding between its atoms. The possibility to deposit polycrystalline diamond films via chemical vapor ...
