After 90 minutes sonoelectrochemical anodization at 20 V in 1 wt % HF the nanotubular structure was formed with an orderly self-aligned with an average length of nanotubular structure approximately 6.8 um (Fig. 3a).
Meanwhile the inner diameter of nanotubular structure obtained within (45 – 64) nm (Fig. 3b).
On top of that, it could change the morphology, composition and reactivity of the TiO2 nanotubular structure [15].

N2 adsorption and TEM analysis revealed that the surfactant-assisted method prepared VCrO/ZrO2 catalysts have wormhole-like mesoporous structure with uniform pore size distribution.
The image clearly demonstrates that the catalyst has a disordered wormhole-like mesopore structure, formed by the agglomeration of the uniform nanoparticles.
N2 adsorption and TEM analysis revealed that the surfactant-assisted method prepared V/Cr-n catalysts have wormhole-like mesoporous structure with uniform pore size distribution.

The compositions and structures of the complexes were characterized by elemental analyses, FTIR, XRD, TG-DSC.
Introduction The coordination chemistry of amino acid Schiff base is of considerable interest due to their biological importance.
To study the thermal decomposition process of various Schiff base complexes is helpful to the understanding of the coordination structure of the complexes [17–19].
The compositions and structures of the complexes were characterized by elemental analyses, FTIR, XRD, TG-DSC.
This method is a simple, convenient, high yield, save energy and environmental friendly, is in accordance with the requirement of green chemistry.

QDs with core-shell structures were developed to enhance some important properties, such as quantum yields (QYs), electronic accessibility, and photo-stability [7, 8].

This approach was originally developed by van Duin et al. to study the hydrocarbon chemistry and the catalytic properties of organic compounds.
The structure of water on a metal surface has also been widely discussed.
Results and discussion 3.1 Properties of bulk nickel Monocrystalline nickel has a face-centered cubic structure.
For each surface orientation, the water molecules were organized in a ‘bilayer’ structure.
The results demonstrate that for all three surface orientations, water molecules are adsorbed in the form of a bilayer structure.

The applied voltage is investigated as a parameter may affect the morphology of the porous structure.
A desired porous structure could be obtained by varying the applied voltage.
Experiment Materials Poly(Butylenes Succinate-co-bytylene Terephthalate)(PBST) with a molecular weight of 20,000g/mol was supplied by Shanghai Institute of Organic Chemistry.
The applied voltage has proved to be a key parameter to affect the formation of porous structure.

With its two-dimensional structure and rich surface chemistry, it provides an ideal platform for the attachment of polymer chains through grafting techniques [26].
Typically, GO has a layered structure.
In case of polyacrylonitrile, the layered structure of GO was visible at lower grafting percentage (200 %).
