BUCKNALL 2 1 State Key Laboratory of Applied Organic Chemistry, College of Chemistry and Chemical Engineering, Lanzhou University, Lanzhou, 730000, China 2 Department of Materials, Oxford University, Parks Road, Oxford, OX1 3PH, UK *Email: Haoli.Zhang@lzu.edu.cn Keywords Soft-lithogarphy; Nano-scale pattern; Polymer blend; Phase separation Abstract In this work, we have investigated phase separation behavior in PS/PVP polymer blend thin films on gold substrates that have chemical stripes of different periods made by microcontact printing.
Anisotropic dewetting [6] and phase separation [7] are attractive self-organizational processes for guiding these instabilities to form structures from nano- to micrometer length scales.
Steiner and colleagues showed that the domains of a phase-separating mixture of polymers in a thin film can be guided into arbitrary structures by a surface with a prepatterned variation of surface energies[7].

Preparation of graphene/Fe3O4/polypyrrole nanocomposite and its adsorption for Cr(VI) ions Wei Yao, Yun Lu* Department of Polymer Science and Engineering, State Key Laboratory of Coordination Chemistry, School of Chemistry and Chemical Engineering, Nanjing University, Nanjing 210093, China yunlu@nju.edu.cn Keywords: nanocomposite, graphene; polypyrrole, Fe3O4, magnetic adsorbent, heavy metal ions Abstract.
Adsorbents possessing activated functionalized surface or hierarchical porous structure with high surface area, show excellent adsorption capacity, such as graphene [5], metal oxides [6], biomaterials [7] and so on, and have been widely used for Cr(VI) removal.
The formation of such novel structure for the Fe3O4@PPy nanospheres may be because the Fe3O4 nanospheres are etched under the acidic condition to form small nanoparticles, and at the same time the Fe3+ ions on/around the nanoparticles oxidize promptly the surrounding monomers to obtain PPy.

The structure and morphology of as-prepared samples were characterized by Raman, SEM, and TEM.
PAA is a slightly crosslinked hydrophilic polymer with a network structure, which is able to absorb hundreds to thousands times water of its own mass to form a stable hydrogel, and integrate with other compounds by its hydrophiolic groups and network structure to form a stable composite.
Based on the unique absorbent characters and three-dimensional network structure of PAA, novel PAA/TiO2 nanocomposites with photocatalytic activity were prepared.
The structure of PAA/TiO2 nanocomposites was determined by FT-Raman spectra.

Abstract: An improved Adler pre-mixed method based on a TFA-catalyzed condensation reaction between aldehydes and pyrroles was developed to synthesize a series of nitro-functionalized A3B-type tetraphenylporphyrins, and all the structures of A3B-type tetraphenylporphyrins were characterized by melting point analysis, electronic absorption spectroscopy, infrared spectroscopy, high-resolution mass spectroscopy, 1H NMR spectroscopy, and elemental analysis.
Porphyrin compounds have planar and conjugated structures, and exhibit strong absorption in visible and near infrared region.
In recent years, porphyrin compounds with various structures have been extensively used as sensitizers for DSCs [3,6].
The nitro-functionalized A3B-type tetraphenylporphyrins (A3B-TPP) compounds give their special asymmetrical structures in the porphyrin macro ring and could be modified directly by other functional groups, which can be used as important precursors to make them applicable in DSCs.

UVand XRD analysis The IR spectrum is a method used to investigate the structure of heteropoly anions widely.
The character peak of the heteropoly salts with Keggin structure appears fingerprint region at the range of the 700-1100cm-1[5].
Combined with IR and UV spectra, it was sure that Na6[Ni(ZrMo11)O39]•20H2O possessed Keggin structure.
The results showed it possessed Keggin structure and had a good thermal stability.

The XRD patterns showed amorphous structure in the BAU-CL sample and had low crystallinity (as FeOOH and Fe2O3 phases) in the BAU-HA and BAU-OA samples.
In addition, ACs have high surface areas, easy control of the surface chemistry, high porosity and the ability for recovering of active metal phase by burning the carbon support.
The results suggest that the formation of Fe-phase particles inside the porous structure of the BAU resulted in a sharp reduction in the SBET and Vt values.
The XRD pattern of the BAU sample shows broad halos, which are typically observed in amorphous materials, at 2θ=25° and 44°, corresponding to the micrographitic structure of ACs [7].

Ru2Si3 crystallizes into two different types of structures: the tetragonal Ru2Sn3-type high-temperature (HT) phase and the orthorhombic Ru2Ge3-type low-temperature (LT) phase.
The crystal structure and/or defect structure are then expected to be controlled by alloying with a substitutional element, especially when the number of valence electrons of alloying element is different from that of the component atoms.
Inspection of crystal structures for phases present in the samples was made by X-ray diffraction (XRD) and electron diffraction in the TEM.
All three SAED patterns exhibit the characteristics of the chimney-ladder structure, which are composed of diffraction spots from the M and X subcells.
