The reinforced shin shell structures are widely used in many fields such as mechanical, architecture, aerospace and shipbuilding, etc.
The leaf can be seen as shin plate structures with stiffener(vein) and the venation distributions are closed related to the external environment load.
Chen[2,3] analysed branching structure form and configuration rule of water platter venation(Fig.1(b)), reaching some bionic structure designs in reinforcing plate distribution for the plane plate and machine tool bar, which was validated stiffness increased while quality reduced.

After sintering process, the high porosity SiC ceramics with three-dimensional network structure can be obtained (Fig.1.a-c).
The rough surface can be found on the surface of SiC network ceramics with microcellular structure.
The P20 steel alloys were filled in poriferous SiC ceramics with three-dimensional network structure.
The results demonstrated that better interface structure was in favour of improving the bonding strength.

In the end, the structure of the material as a whole is maintained (visual control).
Therefore, it makes it possible to trace the changes in nearly all molecular structures.

On the one hand, the transition metal sulfide graphene has a similar layered structure.
In MoS2-tmb-H2O2 nanocomposite structure, MoS2 can promote the electron transfer between TMB and H2O2.
According to Fig. 1, the electrode modified by MoS2-Au-@Pt has better electrocatalytic performance, mainly because of the structure of Au-@Pt.
The structure of Au@Pt is dendritic, and its performance is better than that of Au particles and Pt particles alone.

Introduction Benzimidazole compounds is an important pharmacophore and privileged structure in medicinal chemistry.
Many researchers have reviewed on the mode of action, structure-activity relationships (SAR) and activity of these mono-benzimidazole compounds.
In recent years, bis-benzimidazole compounds have attracted much attention due to the fact that their structure have two benzimidazole containing.
Mixed ligand complexes have a key role in biological chemistry because the mixed chelation occurs commonly in biological fluids as millions of potential ligands are likely to compete for metal ions in vivo[17].
Summary As was mentioned above, benzimidazole compounds is an important pharmacophore and privileged structure in antibacterial agents.

For analyzing structures, BHF and Fe3O4 powder were tested using Panalytical X-ray diffractometer (XRD) using CuKa radiation (wavelength λ =1.5418 Å) in the range of 2θ = 20 – 80°.
XRD pattern of barium hexaferrite (BHF) indicates that all of intensities are the diffraction peaks of BaFe12O19 structure which refer to International Centre for Diffraction Data (ICDD) No. 98-015-7056.
XRD pattern of BHF proved that the precursor of stoichiometric mixtures of BaCO3 and Fe2O3 has successfully formed BaFe12O19 single phase and polycrystalline structure after sintering at 1100 oC for 5 hours.
