The electron-doped superconductors such as Nd2-xCexCuO4+α-δ (NCCO), Pr1-xLaCexCuO4+α-δ (PLCCO), and Eu2-xCexCuO4+α-δ (ECCO) have a tetragonal T’ type structure.
The T’ type structure consists of two important parts, namely a planar CuO2 plane and a charge reservoir plane such as (Nd,Ce)2O2, (Pr,La,Ce)2O2, and (Eu,Ce)2O2 planes.
The CuO2 plane is a conduction layer that is responsible for the superconductivity properties which are influenced by its structure [1].

Evaluating the surface structure, curves of pore size distribution (PSD) and specific surface area (BET) were measured by the N2-adsorption method at 77 K after vacuum evacuation at room temperature.
Figure 1 shows surface structures of HAp granules before and after the supersonic treatment in parenteral fluid (PF-M).
Surface structures of CEZ/parenteral fluids/HAp granules freeze-dried or dried at 293K were shown in Fig.4.
In recent paper [7], elution profiles of vancomycin, gentamicin, and the combination of vancomycin/gentamicin from calcium phosphate cements into PBS at 310 K for 16 weeks were considered from relationships between molecular size of antibiotics and pore structure of specimens.

The chemical composition and structure of the films were investigated by XPS.
XPS spectra of (hydrogenated) carbon nitride films The next step of our study was the characterization of surface structure of CNx and CNx:H films by AFM.
TDMS spectra of CNx and CNx:H These results from Figure 7 indicate a less porous character of CNx films, but their structure remains open too.
The evolution of detected masses is a bit different in CNx and CNx:H, probably due to the difference in density (porous character) and structure of films.
CNx film was quite enough stable but CNx:H film was radically reduced during annealing, probably due to the high porosity character and a high graphite like structure.

Xylose isomerase has high thermostability, and is well known as the model to research the relationship between structure and function [2].
The RasMol V2.7 [11] and DeepView3.7 [12] were used for the structure analysis.
The initial TthXI crystal structure was downloaded from PDB database.
The 70% similarity in sequence is shown in Fig. 1 and extremely similarity in overall structure based on sequence alignments and structural analysis are observed.

The molecular structure of trimer FDN is approximately linear and in fully extended state in solution，but the FDN pentamer structure is spiral curl due to the interactions of the long molecular chains.
Meanwhile, compared with the low molecular weight of FDN, the sulfonated degree of the FDN with the higher molecular weight and electrostatic repulsion are decrease, this is easy to form a coil structure.

The studies on tin monoxide were scarce until the discovery of its ability to be an excellent anode material in tin-lithium rechargeable batteries, coating materials or as effective catalysts in synthetic organic chemistry for cyclization of maleamic acid, polymerization of lactic acids, and degradation of poly (lactic acid) to lactide.
The electronic and structural properties of the tin oxide 1D structures are strongly related to the defects and phase of the crystalline structure.
There are two main crystalline tin oxide structures Figure 1.
On the other hand, the SnOx 1D structures, with 1structures, due to its bulk three dimensional structure nature; however the SnOx ,1structures could be explained trough a oxidation process of scrolled the less stable SnO.
Electronic band structure of (12,0) and (8,8) SnO nanotubes.

The sensor consists of inter-digitated fingers that are made of the same material as the structure to be monitored, Figure 5.
This allows a pseudo corrosion rate 1/(Rp) of the structure to be measured.
This may not be a factor if the structure to be monitored is corroding in a uniform manner, for example steel structures, where the metal loss can be described by the addition of all measured corrosion rates.
