Far-infrared spectroscopic study of CeO2 nanocrystals Abstract: We present the far-infrared reflectivity spectra of 5 nm-sized pure and copper-doped Ce1−x Cu xO2−y (x = 0; 0.01 and 0.10) nanocrystals measured at room temperature in the 50–650 cm−1spectral range. Reflectivity spectra were analyzed using […]
Silver Molybdate and Silver Tungstate Nanocomposites with Enhanced Photoluminescence Abstract: Silver molybdate (Ag2MoO4) and silver tungstate (Ag2WO4) nanomaterials were prepared using two complementary methods, microwave assisted hydrothermal synthesis (MAH) (pH 7, 140 °C) and co-precipitation (pH […]
Rietveld refinement and optical properties of SrWO4:Eu3+ powders prepared by the non-hydrolytic sol-gel method Abstract: We investigated the effect of annealing time on the structure and optical properties of SrWO4:Eu3+ powders prepared by the non-hydrolytic sol-gel method […]
Rapid hydrothermal synthesis and pH-dependent photocatalysis of strontium titanate microspheres Abstract: This manuscript describes a methodology for a rapid hydrothermal conventional synthesis of SrTiO3. The time of synthesis and use of mechanical stirring are related to […]
Light emission during electric field-assisted sintering of electroceramics Abstract: Electric field-assisted sintering has been shown to occur in ion, electron conducting as well as in insulating polycrystalline ceramics. Considerable linear shrinkage with microstructure control at temperatures lower than […]
Anomalous remnant magnetization in dilute antiferromagnetic Gd1−xYxB4 Abstract: Magnetic properties of dilute single crystals of Gd1−xYxB4 (x=0, 0.2, and 0.4) were systematically studied. These antiferromagnetic Shastry-Sutherland compounds display a remnant magnetization MRwhen field cooled below the Néel temperature TN. The […]
Fabrication and structural characterization of bismuth niobate thin films grown by chemical solution deposition Abstract: Bi3NbO7 (BNO) thin films were deposited on Pt/TiO2/SiO2/Si (100) substrates at room temperature from the polymeric precursor method. X-ray powder diffraction and […]
Glucose Biosensor Based on the Hexacyanoferrate 11-Mercaptoundecyl-N ‘,N ”,N ”’-trimethylammonium/6-(Ferrocenyl)hexanethiol Abstract: An amperometric glucose biosensor based on on hexacyanoferrate 11-mercaptoundecyl-N’,N”,N”’-trimethylammonium (HMA)/6-(ferrocenyl)hexanethiol (FT)/GOx modified gold electrode was fabricated and evaluated. The GOx/HMA/FT/Au electrode was characterized using cyclic […]
Crystallinity, morphology and high dielectric permittivity of NiO nanosheets filling Poly(vinylidene fluoride) Abstract: Composite films based on Poly(vinylidene fluoride) (PVDF) polymer filled with Nickel oxide (NiO) nanosheets were prepared via the solution casting method. The […]
Electrical and mechanical characterization of a flexible conducting composite Abstract: Composite films made of poly(vinylidene fluoride) (PVDF) and conducting particles of carbon black (CB) were prepared using a hot press. Using different volume fractions of […]
