It can be found that all of the alloys have a main LaNi5 phase with CaCu5-type hexagonal structure.
When the milling time is 2 h, a noticeable new phase with Ce2Ni7-type hexagonal structure can be observed in the alloy.
However, the CaCu5 structure is known to contain no Mg [14,15].
In addition, milling results in a merging and broadening of the diffraction peaks with increasing milling time, indicating that the crystalline structure progressively transforms to a nanocrystalline or amorphous structure.
The degradation of discharge capacity for the alloy milled for 2 h might result from the multiphase structure.

Western blot pattern illustrated that structure integrity of the most antibodies was kept well, harmful influence given by oxidation of conjugation was very finite.
I.Introduction Magnetic probes has gained widespread interest across several disciplines such as chemistry, life sciences and biomedicine due to its excellent magnetic control properties, and can be used in magnetic separation[1], molecular imaging[2], intracellular hyperthermia[3] as well as drug delivery system[4].
Compared with free anti-α-HCG monoclonal antibodies in lane 1, new blots ~30kDa appeared in lane 2, 3 and 4 that means the antibodies maybe slightly disrupted in structure during sodium periodate oxidative procedure, but NaBH4 reductive and ethanolamine (EA) blocking procedure would not do damage to the structure integrity of antibodies.
Fig. 3 Western blot pattern (A) and gel remain (B) of antibodies before (lane 1) and after the treatment of bioconjugation (lane 2: treated with NaIO4; lane 3:NaIO4+NaBH4; lane 3: NaIO4+NaBH4+EA) D Immunoreactivity of the dex-SPIO–antibody immunoprobes The antibodies can only keep their structure integrity are not enough for the immunoassay, because maybe their space structure has changed.
With the method of SDS-PAGE electrophoresis and immunochromatography, the structure integrity and immunoreactivity of antibodies in dex-SPIO based immunoprobes were certified.

After China joined the WTO, the sales of energy-intensive industries such as chemistry, construction, ferrous metal smelting and other markets have boomed, which promotes the electricity consumption.
The economic development and improvement of electricity consumption will inevitably lead to corresponding changes in the industrial structure and consumption structure and ultimately affect the demand for electricity.
Therefore, in this modern society, the industrial structure is still an important factor affecting power consumption.
Therefore, it is needed to make rational adjustment of industrial structure, utilize the market competition mechanism to eliminate enterprises with high energy consumption in the original industrial structure, reduce the excessive dependence on power consumption, and improve the power use efficiency
Changes in population structure, level of urbanization and consumption structure will promote the increase of power consumption.

The chain of the copolymers with similar structures presented viscous flow pattern.
The structure of copolymer A was analyzed by 1H NMR spectra (Fig.1).
The hydrophobic effect made the linear structure into a huddle up structure showed in (Fig. 3(a)).
The structure of polyester molecular presented certain spiral structure which contained long methylene chain.
With the main chain structure change of PHS, the molecular mass increased.

Morphology and structure of the obtained structures were investigated by scanning electron microscopy combined with energy dispersive X-Ray spectroscopy.
The functionalization degree of the CNF outer surface has a strong influence on the structure, distribution and amount of platinum particles.
Materials with stable and porous structure and a high surface area, having a good interaction with platinum particles are suitable as catalyst support.
Recently, due to their unique properties, carbon based structures became intensively studied, especially carbon nanofibers (CNF).

The chitosan tetramer and glutaraldehyde structures were used to create the Molecularly Imprinted Polymer (MIP) structure.
Thus, the cavity structure of the MIP was created.
The chitosan dimer structure's bond angle and dihedral angle data were obtained from the chitosan crystallography structure (XRD) conducted in a previous study [9].
The structure can be accomplished by generating an electrostatic potential map for the optimized structure.
The dihedral angle of the trans-resveratrol structure was changed to create the cis-resveratrol structure utilized in this modeling.
