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 ...
Sol-gel Synthesis of Anatase Nanopowders for Efficient Photocatalytic Degradation of Herbicide Clomazone in Aqueous Media
(Science of Sintering, 2017)
TiO2 nanopowders were produced by sol-gel technique using TiCl4 as a starting material. For the preparation of crystalline anatase with developed surface area, this aqueous solution has been mixed with 0.05 M or 0.07 M ...
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 ...
Gamma ray-assisted irradiation of few-layer graphene films: a Raman spectroscopy study
(Physica Scripta, 2014)
This paper represents results of a Raman spectroscopy study of gamma-irradiated few-layer graphene thin films at three different doses: 25, 50 and 110 kGy. Graphene thin films were deposited by the vacuum filtration method ...
Covalent Modification of Single Wall Carbon Nanotubes Upon Gamma Irradiation in Aqueous Media
(Hemijska industrija, 2011)
Single wall carbon nanotubes (SWCNTs) were exposed to gamma radiation, absorbing the doses of 25, 50 and 100 kGy in aqueous environment. After the irradiation treatment, the changes in the structure were studied using ...
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 ...
