High concentration of hematite nanoparticles in a silica matrix: Structural and magnetic properties
(Journal of Magnetism and Magnetic Materials, 2009)
The alpha-Fe(2)O(3)/SiO(2) nanocomposite containing 45 wt% of hematite was prepared by the sol-gel method followed by heating in air at 200 degrees C. The so-obtained composite of iron(III) nanoparticles dissolved in glassy ...
Biopolymer-protected CdSe nanoparticles
(Carbohydrate Research, 2009)
A synthetic procedure for the encapsulation of cadmium selenide (CdSe) nanoparticles in a sago starch matrix is introduced. The nanocomposite was investigated using structural, spectroscopic and thermal, methods. TEM ...
Monochromatic imaging technique used to study dc arc plasma under the influence of a transverse magnetic field
(Plasma Sources Science and Technology, 2009)
The monochromatic imaging technique was used for diagnosing atmospheric pressure direct-current (dc) arc plasma with continuous aerosol analyte supply. The arc plasma was subjected to transverse sine wave variable magnetic ...
Synthesis and characterization of silver-poly(methylmethacrylate) nanocomposites
(Colloid and Polymer Science, 2009)
The optical properties of silver nanoparticles embedded in poly(methylmethacrylate) (PMMA) was investigated as well as the influence of silver nanoparticles on the thermal properties of polymer matrix. The average size and ...
Kinetic Study of Sr2+Sorption by Bone Char
(Separation Science and Technology, 2009)
The effect of particle size, bone char mass, initial pH, and metal concentration on the kinetics of Sr2+ sorption by bone char was studied and discussed. Considering the sorbed amounts of Sr2+, solution pH changes, changes ...
The ultrasonic and image analysis method for non-destructive quantification of the thermal shock damage in refractory specimens
(Materials and Design, 2009)
In the present work, Mg-exchanged zeolit and silicon carbide were used as starting materials for obtaining cordierite/SiC composite ceramics with weight ratio 50:50. Samples were exposed to the water quench test from 950 ...
High efficiency production and purification of (86)Y based on electrochemical separation
(Applied Radiation and Isotopes, 2009)
As an intermediate half-life positron emitter (86)Y is an attractive radioisotope for positron emission tomography (PET) studies, particularly for patient specific dosimetry planning of (90)Y-based radiotherapy procedures. ...
Preparation of Porous Silica Ceramics Using the Wood Template
(Materials and Manufacturing Processes, 2009)
Porous silica (SiO(2)) ceramic with a wood-like structure was prepared by wet impregnation tetraethyl orthosilicate (TEOS) into biological template that was derived from linden wood (tilia amurensis). After repeated pressure ...
