It is reported that P plays a very important role in membrane structure, material metabolism, the regulation of enzymes and cell signaling [3, 4].

Structured quadrilateral-cell mesh was chose as computation grid.
One-step irreversible finite-rate chemistry reaction model was employed.

These are the mass spectrometer, which provides data relating to compound structure: the infrared detector, the output from which is a consequence of chemical functionality, and the atomic emission detector which given information concerning elemental composite.
Summary Gas Chromatography is one of the most important tools in chemistry because of its simplicity, sensitivity and effectiveness in separating components of mixtures.

As a recombinant protein, HLC has several special characteristics which are significantly different from animal collagen, such as chemically predictable structure, biocompatibility, low immunogenicity, processability and water solubility [12-15].

Preparation and characterization of poly(L-lactide) /poly(ε-caprolactone) composite films for food packaging application Ji-Yi Yang 1,a, Yu-Yue Qin 1,b*, Jian-Xin Cao1,c,Ming-Wei Yuan 2,d, Shi-Qi Liu 2,e,Ming-Long Yuan 2,f 1Faculty of Chemical Engineering, Kunming University of Science and Technology, Kunming, Yunnan, 650500, China 2School of Chemistry and Biotechnology, Yunnan University of Nationalities, Kunming, Yunnan, 650504, China a bluefrench@hotmail.com, b rabbqy@163.com,cjxcao321@hotmail.com, d yuanmingwei@163.com, emiqimaike@yahoo.com.cn, f yml@vip.163.com Keywords: poly(L-lactide), poly(ε-caprolactone), mechanical property, water vapor permeability, food packaging Abstract: Poly(L-lactide) (PLLA) and poly(ε-caprolactone) (PCL) were produced by solution mixing and cast into films.
For the pure PLLA, the fractured structure indicated brittleness.

Bifunctional Fe3O4@SiO2@Eu-polyoxometalates nanoparticles and study on their magnetism and luminescence Hongyan Zhang 1, Jun Wang 1a, Shaohua Fan 1 1College of Chemistry, Central China Normal University, Wuhan, 430079, China a jwang924@yahoo.com.cn Keyword: Core-shell, Luminescence, Magnetism, Lanthanide Abstract.
Such core-shell nanoparticles show lots of advantages in combination of the properties of different compositions and shelled structures, and core-shell structure provides a method to modify the properties of various nanoparticles.
It is interesting to investigate the incorporation of magnetic nanoparticles in these POM/SiO2 structures.
The core-shell structure, luminescence and magnetic properties were investigated.
The core-shell structured Fe3O4@SiO2@EuW10 particles were achieved.

However, the crosslinking structure of a hydrogel is also an important factor to determine its swelling behavior.
Antigen-antibody entrapment hydrogels without a semi-IPN structure were also prepared by using a native antibody in place of the polymerized antibody [8].
These results mean that the antigen-antibody semi-IPN hydrogel can recognize a specific antigen and then change its structure chemo-mechanically.
However, the antigen-antibody entrapment hydrogel without semi-IPN structure did not show reversible swelling changes.
In the previous paper [10], furthermore, we revealed that introducing semi-IPN structure into stimuli-responsive hydrogels enables rapid response.

Pore structure of carbon is characterized by a quite broad pore size distribution including micro-, meso- and macropore [8].
The pore structure governs transport processes of reactant and products to and from the surface and determine the effective surface area of the active metal.
The crystal structure of Pd/C catalysts were investigated by XRD (D/MAX 2500-V/PC, Rigaku, Japan).
In previous studies, it has been reported that pore structure influences metal dispersion.

To achieve thermal stability of buildings, thermal energy storage materials and structures are used.
In this way, the interior of building interacts with external climatic conditions especially with their rapid changes slower, compared to the lightweight structures based on wood, or wood composites.
On this account, incorporation of PCMs into the structure of materials for lightweight building envelopes represents possible solution for improvement of their heat storage capacity.
However, from the practical point of view, taking into account the real conditions of building structures, only the PCMs working on phase change from the solid to liquid or solid to solid phase can be used.
Additionally, the PCM in liquid phase must be embedded in materials structure, for example by encapsulation.
