To reveal the interface band structure, surface-enhanced Raman spectroscopy (SERS) was employed to analyze the band structure of the TiO2–metal composites.
As an n-type semiconductor catalyst, the energy-band structure of TiO2 consists of a low-energy valence band and a high-energy conduction band.
This is most effective in scattering resonance photons as the size of the plasmonic structure is larger than 50 nm.
Fig. 3 (a) presents the surface structure of the TiO2 (60 nm)–Au nanocomposite prepared by the high-temperature reduction method.

Atomic Structure of Graphene Nanoribbon bandgap Structure (a) and (b) Armchair.
It has been found that the band structures are similar for the two sites in each case.
However it is only applicable for GNR structures in the bilayer form.
The GNR structure is affecting the bandgap opening but with smaller values.

Synthesis of Carbon nanofibers on Iron and Copper Catalysts by Chemical Vapor Deposition Yura Hyun1,a, Haesik Kim2,b and Chang-Seop Lee1,c,* 1Department of Chemistry, Keimyung University, Daegu, 704-701, Korea 2Korea E&S Co.
Introduction Carbon is a substance existing in variable shapes, and its structure and physical property differ from bonding types between carbon atoms.
According to kind of catalysts used and synthesis conditions, carbon nanofiber has various structures; helical architecture in which graphene sheets are coiled in concentric circles; panel structures oriented to fiber lines direction; and, herringbone structure oriented to fish-bone shape [1,2].
It has physical and chemical properties according to its structure.
Such materials range from diamond and graphite of well known carbon allotrope to Fullerene (C60), Graphene, complex-structured CNT (Carbon nanotube) and CNF (Carbon nanofiber) and they are all composed in C-C combination except for different orientation only.

The surface of FA was mainly smooth with some porous structure on the surface (Fig. 3a).
Rugged surface structure containing voids and cracks are suitable for Pb(II) adsorption [19].
This phenomenon resulted in more porous structure and rougher MFA surface.

The magnetic nanocomposite proposed in the present investigation are ferromagnetic nanoparticles with the structure of “iron core - carbon shell”.
The modification of iron-carbon surface by the carboxyl groups and amino groups was performed by a method of aryldiazonium chemistry [7].
Bimodal nanocomposites are formed on the base of fluorescent carbon quantum dots (CQD) and ferromagnetic nanoparticles with an “iron core-carbon shell” structure.

After that, the University of Florida has transformed the original sink, established a structure-similar, larger one.
These researches have contributed to further study on the annular flume hydrodynamic structure.
From a physical chemistry and sediment starting two aspects of theory, combined with the influence that the water flow has on the suspended matter and deposition, analyzed the reason leadingto the changes of TP concentration in each stage.
Scholars simulated or calculated the annular flume internal flow structures with computational fluid dynamicssoftware or numerical methods, opening up a new way for the annular flume experimental study.

The runoff depth variation can indirectly reveal the basin landscape structure change, precipitation, evapotranspiration, water resources use, and etc.
The industrial structure of agriculture in the catchment area has been adjusted, part of glebe is converted into rice field.
(2) The landscape structure change in the catchment area is one of key driving forces for runoff depth variation.
(3) Essentially, the runoff depth variation of the catchment area is a direct response of water balance structures to landscape structure change.

Powder X-ray diffraction patterns revealed that all the samples had cubic structure with Fd-3m space group.The lattice constant was observed to increase with increase in nickel substitution, thus altering the unit cell volume.
The crystalline structure and type of phase were identified using X-ray diffraction meter (Model Bruker AXS, D8 Advance) with Cu-Kα1 radiation.
