europium (eu) doped zno microsphere based nano-sheets were synthesized through hydrothermal method. effects of different concentrations of europium on structural and optical properties of zno nano-sheets were investigated in detail. prepared un-doped and eu-doped zno samples were characterized using x-ray diffraction (xrd), energy dispersive x-ray spectroscopy (edx), scanning electron microscop...

development of an eco-friendly, low cost and high energy density limnpo4 cathode material has attracted much attention due to its high operating voltage vs. li falling within the electrochemical stability window of conventional electrolyte solutions and offers more safety features due to the presence of a strong p-o covalent bond.synthesis of battery materials integrates the battery technology ...

The crystal structure solution of modulated compounds is often very challenging, even using the well established methodology of single-crystal X-ray crystallography. This task becomes even more difficult for materials that cannot be prepared in a single-crystal form, so that only polycrystalline powders are available. This paper illustrates that the combined application of transmission electron...

The Fe nanowires were prepared by Ac electrodeposition method. The two steps anodized aluminum oxides (alumina) were used as templates for electrodeposition of magnetic nanowires. Sulfuric acid was used to anodize aluminum. The pours diameter and growth rate of alumina were investigated. The FeSO4 electrolyte was used for growth of nanowires. The prepared magnetic nanowires were characterized b...

The photoinduced structural dynamics of the atomic wire system on the Si(111)-In surface has been studied by ultrafast electron diffraction in reflection geometry. Upon intense fs-laser excitation, this system can be driven in around 1 ps from the insulating [Formula: see text] reconstructed low temperature phase to a metastable metallic [Formula: see text] reconstructed high temperature phase....

Catalyst-free growth of boron carbide nanowires is achieved by pyrolysis of diborane and methane at 650–750 -C and around 500 mTorr in a quartz tube furnace. Electron-diffraction analysis using a novel diffraction-scanning transmission electron microscopy (D-STEM) technique indicates that the crystalline nanowires are single-crystal orthorhombic boron carbide. TEM images show that the nanowires...

zns  nanoparticles  were  synthesized  via  a  simple  surfactant  free microwave  route.  in  this  synthesis, thioacetamide  was  used  as sulfur  source.  the effects  of different  parameters  such  as  type of zinc precursor,  time  and  power  of  irradiation  on  the  morphology and  particle  size  of  the  products  have been  investigated.  the nanostructures  were  characterized  by ...

We have measured the structure and chemical composition of ultrathin Pd films on Cu 001 using lowenergy electron microscopy. We determine their local stoichiometry and structure, with 8.5 nm lateral spatial resolution, by quantitatively analyzing the scattered electron intensity and comparing it to dynamical scattering calculations, as in a conventional low-energy electron diffraction LEED -IV ...
