Preparation of highly conductive carbon cryogel based on pristine graphene
(Synthetic Metals, 2012)
In this paper we report fabrication and characterization of highly conductive carbon cryogel. The carbon cryogels were prepared by the sol-gel polymerization of resorcinol and formaldehyde in an aqueous surfactant stabilized ...
Synthesis and characterization of the nanometric Pr-doped ceria
(Journal of Alloys and Compounds, 2010)
In this paper nanometric powders of solid solution of the host compound ceria (CeO(2)) with Pr dopant in the lattice were synthesized by self-propagating room temperature (SPRT) synthesis with composition (Ce(0.9)Pr(0.1) ...
Effects of O2+ ions beam irradiation on crystal structure of rare earth sesquioxides
(Applied Surface Science, 2009)
We report the results of ion irradiation influence on rare earth sesquioxides structure, which are materials of practical importance as a radiation resistant ceramics in nuclear applications. Y2O3, Gd2O3 and Er2O3 sesquioxides ...
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 ...
Photocatalytic degradation of metoprolol in water suspension of TiO2 nanopowders prepared using sol-gel route
(Journal of Sol-gel Science and Technology, 2012)
Nanocrystalline titanium dioxide (TiO2) powders have been synthesized by sol-gel method using titanium tetrachloride (TiCl4) or tetrabutyl titanate (Ti(OC4H9)(4) as precursors, different alcohols and calcination temperatures ...
Improved efficiency of sol-gel synthesized mesoporous anatase nanopowders in photocatalytic degradation of metoprolol
(Materials Research Bulletin, 2013)
The structural and morphological properties of mesoporous anatase nanopowders, synthesized by sol-gel method, have been modified by varying the duration of calcination, in order to obtain more efficient photocatalyst than ...
In-Situ and Real-time Monitoring of Mechanochemical Preparation of Li2Mg(NH2BH3)(4) and Na2Mg(NH2BH3)(4) and Their Thermal Dehydrogenation
(Chemistry. A European Journal, 2017)
For the first time, in situ monitoring of uninterrupted mechanochemical synthesis of two bimetallic amidoboranes, M2Mg(NH2BH3)(4) (M=Li, Na), by means of Raman spectroscopy, has been applied. This approach allowed real-time ...
Gamma ray assisted fabrication of fluorescent oligographene nanoribbons
(Materials Research Bulletin, 2012)
In this paper, facile low cost method for production of oligographene nanoribbons is presented. Nanoribbons are produced by gamma ray assisted cutting of oligographene dispersed in cyclopentanone. Width and height of the ...
Characterization of potassium salts of 12-tungstophosphoric acid
(Materials Research Bulletin, 2010)
Potassium salts of 12-tungstophosphoric acid with varying amounts of cation, KxH3 - xPW12O40(x = 1, 2, 3) have been prepared and their characteristics investigated by thermal analyses. FT-IR and micro-Raman spectroscopy ...
Raman study of single wall carbon nanotube thin films treated by laser irradiation and dynamic and isothermal oxidation
(Journal of Raman Spectroscopy, 2012)
The effect of visible and infrared irradiation on the structure of single wall carbon nanotubes (SWCNTs) is still an insufficiently resolved subject. In this paper, we report a detailed study of two types of SWCNT thin ...
