Sol-gel synthesis of alumina-titania nanostructure membrane: preparation and characterization
prepared in a sol-gel process. Thermogravimetric analysis showed that drying progress of the membrane layer is completed at about 560 °C. Scanning electron microscopy analysis displayed a smooth and defect-free layer of alumina-titania membrane after...
Structural and optical properties ofzinc oxide nanopowders doped with Mn
Pure ZnO and Zn1-xMnxO (x=0, 0.02, 0.06, 0.10, 0.15)
nanopowders have been synthesized by sol gel technique at
low temperatures. XRD results indicate that the powder has
a hexagonal polycrystalline ...
Sol-gel synthesis of alumina-titania ceramic membrane: Preparation and characterization
Alumina–titania ceramic membrane with mesopore and narrow pore size distribution was prepared by the sol–gel
process. Observations were based on membrane weight loss, morphology, pore size distribution and BET ...
SYNTHESIS AND STRUCTURE OF PURE AND Mn-DOPED ZINC OXIDE NANOPOWDERS
Zn1−xMnxO (x = 0, 0.02, 0.06, 0.10, 0.15) nanopowders were synthesized by the sol–gel technique
calcinated at low temperatures. By decreasing the grain size in ZnO, the solubility of
magnetic impurity has ...
Electrical and Optical Properties of Nanosized Perovskite-type La0.5Ca0.5MO3 (M=Co,Ni) prepared using a Sol-Gel Method
In this paper the uniformnanopowders of La0.5Ca0.5CoO3– and La0.5Ca0.5NiO3– (LCCO and LCNO) were synthesized fromnitrates of the constituent metal ion, citric acid (CA), and ethylene glycol (EG) by the combined citrate-ethylene ...
Synthesis and structure of PMN–PT ceramic nanopowder free from pyrochlore phase
Single-phase perovskite 0.65PMN–0.35PT nanopowders were synthesized at low temperature by the auto-combustion method. PMN–PT powder with 1 mol% of excess Pb(NO3)2 was prepared from the constituent nitrates and alkoxide ...
Effects of annealing temperature on some structural and optical properties of ZnO nanoparticles prepared by a modified sol–gel combustion method
Abstract
Plate-shaped zinc oxide nanoparticles (ZnO-NPs) were successfully synthesized by a modified sol–gel combustion method. Zinc acetate, pure
water and isopropanol were used as the starting materials. ...
Synthesis and Optical Characterization of Pyroelectric Nanopowders Based on PZT (95/5)
Pb(Zr1−x,Tix)O3 (x = 0.05) with pyroelectric properties have been synthesized by sol–gel technique
at low temperatures. XRD results indicate that the powder has perovskite structure without
secondary phases ...
