Polyurethane/ferrite nanocomposites: preparation and physical properties
(Society of Physical Chemists of Serbia, 2018)
In the present study, polyurethane/ferrite composites (PU-NFs) were prepared using silver ferrite, copper ferrite and zinc ferrite (1 wt.%) by in situ two-step polymerization in solution. PU-NFs based on poly(dimethylsiloxane) ...
A possible mechanism of formation of flower-like MgO/Mg(OH)2 structures by galvanostatic molten salt electrolysis: The concept of local diffusion fields
(Elsevier, 2019)
The processes of electrodeposition from magnesium nitrate hexahydrate melt by galvanostatic regime of electrolysis
have been analyzed. The structure of the formed particles was examined by X-ray diffraction (XRD),
which ...

Brzine nagrizanja kristalografskih ravni silicijuma u vodenom rastvoru TMAH koncentracije 25 tež. % / Etch rates of Si crystallographic planes in a 25 wt % TMAH water solution
(ETRAN Society, 2013)
Nagrizane su silicijumske strukture koje su na
početku nagrizanja definisane kvadratnim ostrvima od
termičkog silicijum dioksida. Stranice kvadrata su projektovane
u različitim kristalografskim pravcima. Određene su ...
Asymmetric polyethersulfone membranes with crosslinked poly(glycidyl methacrylate) particles
(Belgrade : Serbian Chemical Society, 2013)
Polyethersulfone (PES) is frequently used for high-performance ultrafiltration membranes. Functionalization of PES membranes is required to introduce new groups for specific applications, such as affinity membranes for ...
Novel asymmetric polyethersulfone membranes for ultrafiltration application
(Belgrade : Materials Research Society of Serbia; Institute of Technical Sciences of SASA; Vinča Institute of Nuclear Sciences, University of Belgrade, 2012)
Ultrafiltration has recently become popular as a promising separation method in many industrial processes covering fractionation and concentration steps in the food, pharmaceutical and biotechnology industries as much as ...
Novel negatively-charged ultrafiltration membranes made by a combination of immersion precipitation and photopolymerization
(Belgrade : Serbian Chemical Society, 2013)
Ultrafiltration (UF) membranes are currently used in industry for the concentration of proteins and other macromolecules. Performance of UF membranes is generally limited by a trade-off between permeability and selectivity ...
Moisture Mapping of Aeronautical Museum Depot and Galleries by IR Thermography
(Belgrade, Serbia: Military Technical Institute, Belgrade, 2012)
The paper presents the results of moisture detection in the depot and galleries of the Aeronautical Museum in Belgrade. The moisture and changeable temperature conditions are the main causes for corrosion in historical ...
The effect of chlorine dioxide on organophosphorous pesticide degradation
(Serbian Chemical Society, 2019)
This study investigates degradation of organophosphorus pesticide, such as fenitrothion, with chlorine dioxide in deionized water and in real water system (water from River Sava).
Role of electronic excitations in FEBID processes
(Chemistry for Electron-Induced Nanofabrication (CELINA) COST Action CM1301, 2017)
Four mechanisms contribute to the electron-driven degradation of the FEBID precursors: dissociative electron attachment (DEA), dissociative ionization (DI), neutral dissociation (ND) and dipolar dissociation (DD). Thorough ...
