Polysaccharide is one of the major polymer templates for synthesizing selenium nanoparticles because of its high bioactivity and distinctive structure.
Polysaccharides have highly branched chain and active hydroxyl groups, and this structure can absorb and wrap the initial formative selenite nanoparticles to prevent the combination and the growth of selenium particles[11].

Introduction A microcantilever has become a potential device for sensor application in the fields of environment, chemistry, physics, and biology, because of high sensitivity, rapid response, and using low analyte [1,2].
Even the microcantilever was designed to be an atomic force microscope application, we suggest that the sensor system with same microcantilever structure in Fig. 1(a) can be used for chemical sensor, including gas detection.
We suggest that such non-linear curve can be explained by stress analysis of the microcantilever double layer structure [14].

Subsequent rapid solidification of the melted layer might lead to the formation of structures which are not achieved under equilibrium condition [4].
The sample processed with 1350 J/mm showed larger melt dimension (Table 1) with more population of TiC dendritic structure.

Introduction Most cracks in engineering structures are due to deformation effect.
Volume stability of cement-based materials is the ability to resist mortar deformation under the actions of physics and chemistry, which also is the important aspect of cement-based materials’ durability.

BHPTPB has a conjugated propeller-like nonplanar conformation structure containing the peripheral seven aromatic rings which facilitate the formation of π-π interactions.
A series of composite membranes structures and characteristic were evaluated by the 1H-NMR spectroscopy, and thermal stabilities.
The polymer structure was confirmed by 1H NMR spectra.
The structures of the PHP were confirmed by 1H NMR.

The products are of the inverse spinel structure confirmed by X-ray Diffraction.
This paper studies on the preparation of Fe3O4 MNPs doped with Co2+ by the solvothermal method for that cobalt has the more approximate atomic structure with iron compared with the others.
Most of peaks belong to the spinel structure of Fe3O4, which indicates the successful synthesis of Fe3O4 phase.
The doping of Co2+ could not change the crystals structure of Fe3O4.
The doped Fe3O4 MNPs have the inverse spinel structure confirmed by X-ray diffraction.
