A novel type of 1D nanostructure with characteristics between those of a solid nanowire and a hollow nanotube, i.e. a peashell-like nanostructure comprising a 1D wire with periodically embedded hollow nanobubbles, is presented for the first time; as an example, MgO peashell-like nanostructures exhibit extraordinary dielectric and magnetization properties.

In recent years, a number of research groups have begun developing nanofabrication methods based on DNA self-assembly. Here we review our recent experimental progress to utilize novel DNA nanostructures for self-assembly as well as for templates in the fabrication of functional nano-patterned materials. We have prototyped a new DNA nanostructure known as a cross structure. This nanostructure ha...

A variety of patterns of well-ordered perovskite-type complex oxide nanostructures were obtained by pulsed laser deposition (PLD) on conductive single crystalline substrates through latex sphere monolayer and double-layer masks. Patterns obtained via deposition through hexagonally close packed (hcp) latex sphere monolayers include the usual arrays of hexagonally ordered nanoislands, hexagonal a...

we report on the synthesis, morphology, chemically and structurally of la2o3-co3o4-zro2 nanostructure. the la2o3-co3o4-zro2 nanostructure was synthesized by a method based on the co-precipitation. composite powders have been characterized by xrd (x-ray diffraction), sem (scanning electron microscopy) and bet (brunauer-emmett-teller). x-ray diffraction showed the formation of nano crystalline, l...

In this work, PbSe and PbTe sensitized TiO2 solar cells were fabricated. PbSe and PbTe nanostructure was deposited on the TiO2 surface via a drop cast method. The fabricated surfaces were examined by atomic force microscopy (AFM). Also the optical properties of the layers were studied by diffuse reflectance spectroscopy (DRS) spectra. The morphology of the surfaces was obtained by scanning elec...

BiOCl microflowers were synthesized using bismuth nitrate pentahydrate and sodium chloride by microwave (MW) assisted synthesis method for 23 minutes at 180 W. Scanning electron microscopy (SEM) studies revealed a unique morphology of flower-like assemblies comprised of nanosheets. The X-ray diffraction (XRD) pattern showed that a highly pure and crystalline phase has been obtained. The energy ...

A simple, time effective and cost effective, methos was reported for synthesis of nickel oxide nanostructure. The NiO nanostructure was synthesized by gamma-irradiation method from NiSO4 precursor. The solution was irradiated by 60Co gamma-ray source at the dose rate of 40 Gy/min for determined time. The synthesized powders are characterized by means of X-ray powder diffraction (XRD), Energy-di...

In the present investigation, a ZnO nanostructure was synthesized by means of precipitation and sonochemical methods. The X-ray diffraction (XRD) pattern indicated that the wurtzite structure of ZnO had a hexagonal symmetry and there was no impurity. The average ZnO particles crystallite size was calculated at about 41 nm. The SEM and TEM images revealed nanostructure ZnO particles with a cauli...
