Synthesis and characterization of nanocrystalline polyhedral oligo silsesquioxanes (POSS) with cross-linkable functionalities
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
A facile synthesis was employed for three polyhedral oligo silsequioxanes (POSS), obtaining incompletely condensed structures with fern-like and cubic morphologies. Proton nuclear magnetic resonance spectroscopy (H-1 NMR) ...
Recyclability of technology metals from E-waste: Case study of in and Ga recovery from magnetic fraction
(Association of Metallurgical Engineers of Serbia, 2019)
This study presents the results of the theoretical assessment and a preliminary experimental investigation of technology metals (TM) recovery from magnetic fraction obtained after mechanical treatment of waste printed ...
New spirohydantoins derived from beta-tetralone: design, synthesis and evaluation of their pharmacokinetically relevant propertie
(Savez hemijskih inženjera, Beograd, 2019)
To create new anticonvulsant drugs, two series of spirohydantoins derived from beta-tetralone bearing a 4-substituted benzyl group (1a-1g) or a 2-(4-substituted phenyl)-2-oxoethyl group (2a-2f) in position 3 of the hydantoin ...
Influence of 1,2,3,4-butanetetracarboxylic acid concentration on in situ synthesis of cuo/cu2o nanoparticles on cotton and viscose rayon fabrics
(Editura Acad Romane, Bucuresti, 2019)
This study discusses the possibility of in situ synthesis of Cu-based nanoparticles (NPs) on cotton and viscose rayon fabrics previously modified with 1,2,3,4-butanetetracarboxylic acid (BTCA) of different concentrations, ...
Improving the synthesis process of tribological materials based on tin sulphides by adding graphite as additive
(Srpsko hemijsko društvo, Beograd, 2019)
The aim of this research was to study the effect of graphite addition in the process of synthesis of tribological materials based on tin sulphides. The tin sulphides powders were synthesized from selected precursors by ...
Synthesis of novel wo3/zrsio4 catalysts for dehalogenation of halogenated hydrocarbons
(Savez inženjera metalurgije Srbije, Beograd, 2019)
This research aimed to develop a novel catalyst based on WO3/ZrSiO4 system for halogenated hydrocarbons processing. The production method of this catalyst involved extrusion and as such was simplified compared to thermo-chemical ...
Kinetic models of swelling and thermal stability of silver/poly(vinyl Check far alcohol)/chitosan/graphene hydrogels
(Elsevier Science Inc, New York, 2019)
Silver nanoparticles (AgNPs) were synthesized by in situ electrochemical reduction of Ag+ ions in poly (vinyl alcohol)/chitosan/graphene (PVA/CHI/Gr) hydrogel matrices with different concentrations of chitosan. The ...
PREPARATION, CHARACTERIZATION AND ANTIBACTERIAL ACTIVITY OF CLINOPTILOLITE/THYMOL COMPOSITES
(Srpsko zeolitsko drustvo, Beograd, 2019)
Composites based on natural zeolite – clinoptilolite and thymol were prepared using
two different approaches: 1) wet impregnation (WI) and supercritical solvent impregnation
(SSI). The SSI was more superior since it ...
Nitrogen plasma surface treatment for improving polar ink adhesion on micro/nanofibrillated cellulose films
(Springer, Dordrecht, 2019)
We find that nitrogen plasma treatment of micro/nanofibrillated cellulose films increases wettability of the surface by both liquid polar water and nonpolar hexadecane. The increased wetting effect is more pronounced in ...
