Ex situ integration of iron oxide nanoparticles onto exfoliated expanded graphite flakes in aqueous suspension
(Journal of the Serbian Chemical Society, 2014)
Hybrid structures composed of exfoliated expanded graphite (EG) and iron oxide nanocrystals were produced by an ex situ process. The iron oxide nanoparticles coated with meso-2,3-dimercaptosuccinic acid (DMSA), or poly(acrylic ...
Raman Study of Vanadium-Doped Titania Nanopowders Synthesized By Sol-Gel Method
(International Journal of Modern Physics B, 2010)
Pure titania (TiO(2)) nanopowders and TiO(2) doped with 10 mol % of vanadium ions (V(3+)) are synthesized by sol-gel method. The dependence of structural characteristics of nanopowders on synthesis conditions is investigated ...
Raman spectroscopy of graphene nanoribbons synthesized by longitudinal unzipping of multiwall carbon nanotubes
(Physica Scripta, 2014)
Graphene nanoribbons (GNRs) were synthesized by longitudinal unzipping of multiwall carbon nanotubes (MWCNTs), and changes in Raman spectra were followed. Transmission electron microscopy was used to investigate the ...
Yttrium Orthoferrite Powder Obtained by the Mechanochemical Synthesis
(Science of Sintering, 2017)
Yttrium orthoferrite (YFeO3) powder was prepared by a mechanochemical synthesis from a mixture of Y2O3 and alpha-Fe2O3 powders in a planetary ball mill for 2.5 h. The obtained YFeO3 powder sample was characterized by X-ray ...
OPO laser light absorption and evolutionary behaviour of SWCNT thin films
(Journal of Optoelectronics and Advanced Materials, 2012)
In this paper we report a systematic study on the properties of irradiated SWCNT films by high power, pulsed visible irradiation of OPO laser in the range from 430 nm to 800 nm. Raman analysis showed that metallic and ...
Monolayer graphene films through nickel catalyzed transformation of fullerol and graphene quantum dots: a Raman spectroscopy study
(Physica Scripta, 2014)
In this paper we present synthesis of monolayer graphene islands. These films are deposited through nickel catalyzed transformation of fullerol and graphene quantum dots. Carbon doped nickel films are produced by autocatalytic ...
Analysis of SiO2 thin film deposited by reactive sputtering
(Materials Science Forum, 2006)
SiO2 layers were deposited by reactive d.c ion sputtering (using 1 keV Ar+ ion gun) from a high purity silicon target in an oxygen ambient. The base pressure in the deposition chamber was 4.7-10(-9) mbar, and the substrate ...
The Effect of Oxidation on Structural and Electrical Properties of Single Wall Carbon Nanotubes
(Hemijska industrija, 2011)
Single wall carbon nanotubes (SWCNTs) represent an important group of nanomaterials with attractive electrical, chemical, and mechanical properties. In this work we have investigated the structural, optical and electrical ...
Cd1-xMnxS nanoparticles: Far-infrared phonon spectroscopy
(Materials Science Forum, 2005)
Phonon spectra of Cd1-xMnxS (x = 0; 0.01; 0.05; 0.1; 0.15; 0.3) nanoparticles (d similar to 4.5 rim) have been investigated by far-infrared reflection (FIR) (spectral range 40 - 600 cm(-1), temperature range 80-300 K) and ...
