Carboxylic acids and polyethylene glycol assisted synthesis of nanocrystalline nickel ferrites
(Elsevier Sci Ltd, Oxford, 2013)
Different synthesis methods for the preparation of nanocrystalline nickel ferrites are reported: the thermal decomposition of precursors, made of: (i) metal-nitrate salts with carboxylic acids (citric, malonic and tartaric), ...
Lead immobilization by geopolymers based on mechanically activated fly ash
(Elsevier Sci Ltd, Oxford, 2014)
In this paper, the effectiveness of geopolymers based on initial and mechanically activated fly ash in immobilization of lead was investigated. Fly ash (FA) was firstly mechanically and then alkali activated at room ...
Spark plasma sintering of ZrC-SiC ceramics with LiYO2 additive
(Elsevier Sci Ltd, Oxford, 2013)
Spark plasma sintering (SPS) of ZrC-SiC composite powders in the presence of LiYO2 sintering additive was studied. The starting powders were obtained by a carbothermal reduction (CTR) of natural mineral zircon (ZrSiO4), ...
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 ...
The dependence of the photocatalytic activity of TiO2/carbon nanotubes nanocomposites on the modification of the carbon nanotubes
(Elsevier Sci Ltd, Oxford, 2014)
Nanostructural TiO2/modified multi-wall carbon nanotubes photocatalysts were prepared by hydrolysis of Ti(iso-OC3H7)(4) providing chemical bonding of anatase TiO2 nanoparticles onto oxidized- or amino-functionalized ...
Preparation of low cost alumina nanofibers via electrospinning of aluminium chloride hydroxide/poly (vinyl alcohol) solution
(Elsevier Sci Ltd, Oxford, 2013)
Alumina nanofibers are very suitable materials for use as reinforcement in a great variety of high performance composite materials. Nanosized alumina fibers were prepared from the aluminum chloride hydroxide/poly (vinyl ...
Substrate preheating and structural properties of power plasma sprayed hydroxyapatite coatings
(Elsevier Sci Ltd, Oxford, 2016)
The aim of the present study was to investigate the influence of substrate preheating on the structural properties of hydroxyapatite coatings (HACs) deposited by using the high power (52 kW) laminar plasma jet. The deposition ...
Highly ordered macroporous gamma-alumina prepared by a modified sol-gel method with a PMMA microsphere template for enhanced Pb2+, Ni2+ and Cd2+ removal
(Elsevier Sci Ltd, Oxford, 2017)
The adsorption performance of three-dimensionally ordered macroporous (3DOM) gamma-alumina was investigated for enhanced Pb2+, Ni2+ and Cd2+ removal. The synthesis was based on a modified sol-gel method using a colloidal ...
Composite nanostructured hydroxyapatite/yttrium stabilized zirconia dental inserts - The processing and application as dentin substitutes
(Elsevier Sci Ltd, Oxford, 2018)
The objective of the study was to process nano-structured hydroxyapatite/yttrium-stabilized zirconia bioceramic and to investigate the possibilities of its application as dentin replacement in the form of dental inserts. ...
Polycrystalline (Y0.7Gd0.3)(2)O-3:Eu3+ ceramics fabricated by Spark Plasma Sintering: Densification and microstructure development
(Elsevier Sci Ltd, Oxford, 2014)
Using Spark Plasma Sintering it is possible to produce polycrystalline ceramics of very fine microstructure and good mechanical properties. This work presents the fabrication of such ceramics using Eu3+-doped (Y0.7Gd0.3)(2)O-3 ...
