SEM Images ((a) grid-like structure and (b) corresponding Magnified structure) of the Lower Surface of the Lotus Leaf Figure2.
Such micro-sized uniformly distributed granule structure can be regarded to be similar to the surface unitary structure observed on the lower surface of lotus leaves.
Such unitary structure surface shows feeblish hydrophobicity.

Fluorescent compounds generally compose of the chemical structure having conjugated double bond such as aromatic ring.
These results indicate the difference in the chemical structures of the monomer and its macromer.
The chemical structure of this molecule was characterized by 1H-NMR spectroscopy and the spectra of the monomer and its macromer are shown in Figure 3.
The number of protons present in the macromer structure was determined by comparing well-defined peak integrals between those assigned to the monomer and its macromer.
Two monomer radicals then combine to form the following dimeric structure.

Beta-Cyclodextrin-Maltodextrin Inclusion Complex of Lavender Oil: Preparation and Physical Properties T Chimsook1 1Faculty of Science, Program of Chemistry, Program of Applied Chemistry, Maejo University, Chiang Mai, Thailand 50290 Corresponding author: pitiporn@mju.ac.th Keywords: Lavender oil, Inclusion complexes, Cyclodextrin Abstract.
Moreover, changes in crystal structure before and after microencapsulation were assessed using X-ray diffraction (XRD) with Cu-K𝛼 radiation at 40 kV and 40 mA.
All the diffraction lines could be indexed to beta cyclodextrin decahydrate (JCPDS card 00-054-1476) with a monoclinic structure.
This indicated a structural transition in 𝛽-CD from a cage-type to a channel-type structure during microencapsulation.

Layered structures of these compounds have their peculiarities, which are of a special kind of nano-structured, thus, they provide a new way of thinking for the synthesis of new nano-layered structure of compounds.
The detailed structure of FeOCl was reported by Lind,' confirming the earlier work of Goldsztaub., The unit cell parameters are a = 378.0, b = 791.7, and c = 330.2 pm.
The structure consists of a corrugated (in two dimensions) iron-oxygen framework sandwiched between planes of chlorine atoms to form one layer of the lamellar material.

Impacts of Uranyl Ion on the Structure and Function of Cytochrome b5 His39Ser Mutant Dun Wan, Li-fu Liao and Ying-Wu Lin* School of Chemistry and Chemical Engineering, University of South China, Hengyang 421001, China linlinying@hotmail.com Keywords: Uranium; Heme proteins; Metal-binding site; modeling; Toxicity.
Molecular modeling study The structure of cyt b5 H39S was modeled based on the crystal structure of bovine liver microsomal cyt b5 (PDB entry 1CYO) [12], using a procedure similar to previous modeling cyt c axial mutants [13].
The modeling structure was analyzed using VMD 1.8.7 (Visual Molecular Dynamics) [16].

The structure and properties of the magnesium-based aerogels were featured by TEM, XRD and BET.
These nanoscale materials exhibit unusual surface chemistry and catalytic properties and, compared to other MgO samples, are more chemically reactive.
Because it will destroy Mg(OH)2 aerogel’s porous structure.
After 500℃ heat treatment by 4 hours, the magnesium aerogel remains its interconnected network structure.

It showed the crystalline structure in the scanning electron microscope, then preliminary analysis the mechanism on this based.
Fig.1(b) was the blackening film morphology map which was amplified 30000×, and we can see that the blackening film has reticular structure, dispersed.
XRD spectra of the blackening films In order to determine the phase of the blackening films structure, use TD-3000 X-ray diffraction to analysis.
Fig.3 XRD of the blackening film The XRD patterns in Fig.3 showed that the the blackening film was polycrystalline composite coating, which were composited with face-centered lattice structure of elemental antimony that was deposited on the metal surface and a small amount of body-centered cubic lattice structure of Al2O3·2SiO2·3H2O.
The analysis of the blackening film by SEM, XPS, XRD showed that the conversion film was composite crystalline film which was formed by elemental antimony (face centered orthorhombic lattice structure) and a small amount of Al2O3·2SiO2·3H2O (body-centered cubic lattice structure).

Pellets of about 1 mm were selected and used in the characterization of the pore structure of the solids.
Reaction temperatures too low or too high both were not good for the formation of the porous pore structure.
