Rhombohedral Symmetry

AbstractTin(II) ethylene glycolate is prepared from freshly precipitated “tin(II)-hydroxide” on heating in ethylene glycol under reflux. The colourless single crystals, slightly distorted cubes, exhibit rhombohedral symmetry (R3̄-C3i2, ah = 1547.7 pm, cn= 871.6 pm, Z = 18). The structure is a 3-dimensional networks of linked tin(II) ethylene glycol chelates.

Morphology Changes

The superhydrophobicity of polyvinylidene fluoride (PVDF) membranes can be achieved by adding a small amount of hexagonal boron nitride nanosheets ( h-BNNSs) during the preparation process. The h-BNNSs can be fabricated by two steps of facile ultrasonication of commercial h-BN powders in water and subsequent centrifugation process. The introduction of a small amount of h-BNNSs into PVDF will result in structure and morphology changes of final PVDF membranes. The changes of the structure and morphology can significantly reduce the surface wettability of PVDF membranes, even generating superhydrophobicity. However, the superoleophilicity of PVDF membranes is well kept, which is not influenced by the introduction of h-BNNSs. The excellent superhydrophobicity and superoleophilicity make these porous h-BNNS/PVDF composites to be promising candidates for separating oil and water as membranes in practical oil-polluted waste water treatment.

The Eu

To improve the photocatalytic properties of titania photocatalyst by incorporated Eu element during electrochemical oxidation, Eu-doped titanium oxide nanotube was synthesized by anodic process in an ethylene glycol electrolyte with Eu (NO3)3 as an additive. The crystalline structure and surface characteristics of Eu-doped titania nanotube were investigated. The XPS results indicate the migration of the europium element into the titania nanotube layer from mixture electrolyte during electrochemical oxidation. The Eu-doped titania nanotubes show much higher activity of dye degradation.
