Tio2/zro2 thin films synthesized by pld in low pressure n-, c- and/or o-containing gases: structural, optical and photocatalytic properties
(Inst Materials Physics, Bucharest, 2012)
Doped TiO2/ZrO2 films were obtained by Pulsed Laser Deposition method under different synthesis conditions. The onset of absorption spectra was red shifted for the films obtained in N-2 containing gas mixtures, while a ...
Novel composite scaffolds based on alginate and Mg-doped calcium phosphate fillers: Enhanced hydroxyapatite formation under biomimetic conditions
(Journal of Biomedical Materials Research Part B-Applied Biomaterials, 2021)
In the present study, we synthesized hydroxyapatite (HAP) powders followed by the production of alginate based macroporous scaffolds with the aim to imitate the natural bone structure. HAP powders were synthesized by using ...
The formation of oxide nanoparticles on the surface of natural clinoptilolite
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
Nanoparticles of NiO, ZnO and Cu(2)O crystallize when the Ni-, Zn- and Cu-exchanged natural clinoptilolite, respectively, are dehydrated by heating in air at 550 degrees C. The dehydration of Mn-exchanged clinoptilolite ...
Thermal, morphological, and mechanical properties of ethyl vanillin immobilized in polyvinyl alcohol by electrospinning process
(Springer, Dordrecht, 2014)
In this study, polyvinyl alcohol (PVA) nanofibers with ethyl vanillin as an active compound were prepared using electrospinning technique. The final products of electrospinning process were in the form of nanofibers films. ...
Structural and biological evaluation of lignin addition to simple and silver-doped hydroxyapatite thin films synthesized by matrix-assisted pulsed laser evaporation
(Springer, Dordrecht, 2015)
We report on thin film deposition by matrix-assisted pulsed laser evaporation of simple hydroxyapatite (HA) or silver (Ag) doped HA combined with the natural biopolymer organosolv lignin (Lig) (Ag:HA-Lig). Solid cryogenic ...
Differentiation between Pseudomonas and Stenotrophomonas species isolated from fish using molecular and MALDI-TOF method / Diferencijacija Pseudomonas i Stenotrophomonas vrsta izolovanih iz riba primenom molekularnih metoda i MALDI-TOF metode
(Univerzitet u Beogradu - Fakultet veterinarske medicine, Beograd, 2016)
For the purpose of precise antibiotic susceptibility testing it is necessary to clearly distinguish Pseudomonas and Stenotrophomonas genera, considering acquired resistance of Pseudomonas species, as well as the intrinsic ...
Design of biopolymer carriers enriched with natural emulsifiers for improved controlled release of thyme essential oil
(Wiley, Hoboken, 2020)
This work aims to characterize a novel system for thyme essential oil delivery based on the combination of natural emulsifiers (soy protein and soy lecithin) and alginate, produced using the extrusion technique. The ...
Synthesis, Structure and Properties of Nickel-Iron-Tungsten Alloy Electrodeposits PART I: Effect of Synthesis Parameters on Chemical Composition, Microstructure and Morphology
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2015)
Kinetic and operational electrolysis parameters determine the polarization characteristics, electrodeposition current efficiency, morphology, chemical composition and microstructure of nickel/iron/tungsten alloy deposits. ...
Electrochemical synthesis of nanosized hydroxyapatite/graphene composite powder
(Springer Japan Kk, Tokyo, 2015)
Electrochemical synthesis was employed to prepare a novel hydroxyapatite/graphene (HAP/Gr) composite powder suitable for medical applications as a hard tissue implant (scaffold). The synthesis was performed in a homogeneous ...
Optical properties CaWO4:Nd3+/PMMA composite layered structures
(Elsevier, Amsterdam, 2019)
In this article, we report characterization of the layered composite fabricated from Nd3+ doped calcium twigstate single crystal (CaWO4 :Nd3+) and poly(methyl methacrylate) - PMMA with various organic-inorganic interfaces: ...
