Preparation and characterization of poly(vinyl butyral) electrospun nanocomposite fibers reinforced with ultrasonically functionalized sepiolite
(Elsevier Sci Ltd, Oxford, 2014)
This study presents an investigation of the effects of the processing conditions on the uniformity, morphology and structure of patterned nanofibrous mats of electrospun poly(vinyl butyral)/sepiolite (PVB/Sep) nanocomposite ...
Core-shell superparamagnetic iron oxide nanoparticle (SPION) clusters: TEM micrograph analysis, particle design and shape analysis
(Elsevier, 2016)
For the first time, particle shape analysis of silica coated iron oxide (maghemite/magnetite) nanoparticle clusters (core-shell nanostructures) is discussed using computational methods. We analyzed three samples of core-shell ...
Crystallization behavior and sintering of cordierite synthesized by an aqueous sol-gel route
(Elsevier Sci Ltd, Oxford, 2012)
The purpose of the research was to investigate crystallization behavior and sintering of cordierite synthesized by a low-price aqueous sol gel route starting from silicic acid and magnesium and aluminum salts. Viscous ...
Visible-light active mesoporous, nanocrystalline N,S-doped and co-doped titania photocatalysts synthesized by non-hydrolytic sol-gel route
(Elsevier Sci Ltd, Oxford, 2016)
Visible-light active mesoporous N,S-doped and co-doped anatase TiO2 powders were synthesized by non-hydrolytic sol-gel route, starting from TiCl4 and Ti((OPr)-Pr-i)(4) dissolved in cyclohexane or dimethyl sulfoxide, later ...
Influence of different pore-forming agents on wollastonite microstructures and adsorption capacities
(Elsevier Sci Ltd, Oxford, 2017)
In this study, porous macro- and micro-cellular wollastonite-based ceramics was synthesized. A ceramic precursor, methylhydrocyclosiloxane, together with micro-sized CaCO3, was used as a starting material. After 20 min of ...
CdS quantum dots sensitized TiO2 nanotubes by matrix assisted pulsed laser evaporation method
(Elsevier Sci Ltd, Oxford, 2016)
Within this study a matrix assisted pulsed laser evaporation technique was employed for deposition of CdS quantum dots onto TiO2 nanotubes. The number of laser pulses and laser fluence were varied to control the amount of ...
Change in structural, ferroelectric, and magnetic properties of bismuth ferrite induced by doping with gadolinium
(Elsevier Sci Ltd, Oxford, 2019)
Bismuth ferrite, BiFeO3, was doped with a wide range of concentrations (0-30%) of Gd in order to investigate structural, ferroelectric, and magnetic properties and their correlation. Powder samples of Bi1-xGdxFeO3 (x = ...
Structure and luminescence properties of Eu3+ doped TiO2 nanocrystals and prolate nanospheroids synthesized by the hydrothermal processing
(Elsevier Sci Ltd, Oxford, 2012)
We report on a new approach to the synthesis of Eu3+ doped TiO2 nanocrystals and prolate nanospheroids. They were synthesized by shape transformation of hydrothermally treated titania nanotubes at different pH and in the ...
Bioactive glass-ceramics prepared by powder sintering and crystallization of polyphosphate glass containing strontium
(Elsevier Sci Ltd, Oxford, 2017)
Melt-quenching method was employed for obtaining a glass-ceramic with the following composition 42P(2)O(5). 40CaO.5SrO.10Na(2)O.3TiO(2) (mol%) glass. The crystallization and sintering behavior of glass have been studied ...
Mg/Cu co-substituted hydroxyapatite - Biocompatibility, mechanical properties and antimicrobial activity
(Elsevier Sci Ltd, Oxford, 2019)
The aim of this study was to improve the mechanical properties and to optimize antimicrobial activity of hydroxyapatite (HAP) by simultaneous doping with Mg and Cu ions in order to obtain material that would be able to ...
