in this research fe-tio2 nanocomposites with different molar ratios of fe/ti were prepared as nano-photocatalyst using a modified sol-gel process at ambient temperature. crystallographic properties of nanocomposites were characterized by x-ray diffraction (xrd). surface morphology and mean particle size of nanocomposites were specified by field emission scanning electron microscopy (fesem) and ...

Abstract: composition of MgO and nano boehmite. The reactant and potassium chloride, as the reaction media, were fired at800-1000 °C at different dwell times (0.5-5 h) in the ambient atmosphere. After washing and filtration, the spinel nanopowder was characterized by X-ray diffraction (XRD), Scanning electron microscopy (SEM), and Brunauer-Emmett-Teller (BET) techniques. It was demonstrated tha...

Silica sol nano-abrasives with large particle are prepared and characterized by TEM, PCS and Zeta potential in this paper. Results show that the silica sol nano-abrasives about 100nm are of higher stability (Zeta potential: -65mV) and narrow distribution of particle size. And then alkali CMP slurries for tungsten containing self-made silica sol nanoabrasives are prepared and applied. CMP result...

Bio-based membranes were obtained using Polyamide 11 (PA11) from renewable sources and a nano-hybrid composed of halloysite nanotubes (HNTs) filled with lysozyme (50 wt % of lysozyme), as a natural antimicrobial molecule. Composites were prepared using an electrospinning process, varying the nano-hybrid loading (i.e., 1.0, 2.5, 5.0 wt %). The morphology of the membranes was investigated through...

An H-shaped nano-aperture used as a high efficient near-field radiator is demonstrated. The transfer efficiency higher than unity and nanoscale radiation spot can be achieved simultaneously in the near field compared with regular apertures. The radiation enhancement is ascribed to the fundamental electric–magnetic field propagating in the TE10 mode concentrated in the gap between the ridges, wh...

The optimal conditions of inkjet-printed nano-silver suspension and silver nitrate solution for fabricating continuous narrow conductive lines on a polyimide substrate are investigated. In addition, the effects of driving pulse voltage and droplet coverage on the bulging of as-printed conductive lines are also examined.

In this paper dielectric properties of LiNbO3:Gd single crystals at temperatures ~ 290–490 K at narrow frequency range (0.5–10 6 Hz) are presented. The influence of growth conditions was also investigated. The anomalies on dielectric plots depend on the development of the microand nano-domain structure.

The refraction of a localized narrow beam is significantly different from that of a plane wave. As the beam width decreases to be in the order of the wavelength, the refraction behavior deviates noticeably from Snel’s law, and when the width of a light beam is smaller than about one fifth of the wavelength of the incident light, finite-difference time-domain simulations demonstrate that refract...

Ultrathin metal coordination Prussian blue (PB) nanoribbons with tunable width have been successfully synthesized. The morphology and microstructure of PB nanoribbons are characterized using UV-vis, FT-IR, AFM, TEM and XRD. PB nanoribbons synthesized possess an ultrathin thickness of approximately 1 nm and narrow width. The width of PB ribbons can be tuned by varying the chain length of polymer...
