Layered TiO2 sheets with high Cr(VI) photoreduction ability were prepared by template free solvothermal method using ethylene glycol (EG) as structure directing agent. EG linking function in the layered confirmed SEM, TEM, FTIR, XPS and so on. Moreover, obtained large sized (20~50 μm length, about 5~10μm width) assembled N‐doped thin 1.2nm gap between, resulting very surface area (327.5 m2/g) a...

The three dimensional perovskite manganites R1−xAxMnO3 in the range of holedoping x > 0.5 are studied in detail using a double exchange model with degenerate eg orbitals including intraand inter-orbital correlations and near-neighbour Coulomb repulsion. We show that such a model captures the observed phase diagram and orbital-ordering in the intermediate to large band-width regime. It is argued...

In this study we developed a spatial reasoning-based method of automatically extracting roads in a densely populated suburb of Auckland, New Zealand from IKONOS data. First, all of the four multispectral bands were grouped into 20 clusters in an unsupervised classification, two of which corresponded to road networks. This intermediate result was then converted into a binary image of road and no...

We prove that if a group G is systolic, i.e. if it acts properly and cocompactly on a systolic complex X, then an appropriate Rips complex constructed from X is a finite model for EG.

We review the solvothermal synthesis, using a mixture of ethylene glycol (EG) and water as the solvent, of zinc oxide (ZnO) particles having spherical and flower-like shapes and hierarchical nanostructures. The preparation conditions of the ZnO particles and the microscopic characterization of the morphology are summarized. We found the following three effects of the ratio of EG to water on the...

dutch elm disease is one of the most destructive vascular wilt diseases in the world. ophiosatoma ulmi and o. novo-ulmi had been the most important causal agents of the dutch elm disease in the last century. so, in order to manage of disease, their identification and distinction is necessary. these fungal species were distinguished based on morphological, physiological and molecular characters....
