Introduction The structure and property of packaging materials change due to the effect of high-energy radiation, especially plastics widely used in food and medicine packaging.
PP powder (F401) was obtained from Luoyang Petrochemistry Factory (China); the stabilizer was used was IR1010 and DLTP supplied by the 2nd Tianjin Chemistry Company (China).The TMPTA (trimethyrol propane trimethacrylate) purchased from Beijing Oriental Chemical Co., Ltd.
The structure and property between PP and PA-6 are different, especially their polarities, their interphase compatibility is very bad, and there are many micro weakness in the system, so the strength and rigidity of PP/PA-6 blends without mPP was not improved compared with PP1, the interphase compatibility of PP/PA-6 blends was improved effectively, and the strength, rigidity and toughness (such as ε) of the system increased with the addition of compatibilizer mPP, while the ε of PP1/mPP/PA decreased greatly, it may be due to the lower content of mPP added.
It can be hardly observed that there was the structure of phase separation between PA and PP (see A4 in Fig.3, B1 and B2 in Fig.4).

There are three main steps in the preparation of nanoparticles that should be evaluated from a green chemistry perspective: the choice of the solvent medium used for the synthesis, the choice of an environmentally benign reducing agent, and the choice of a nontoxic material for the stabilization of the nanoparticles [10].The majority used chemicals in the reported methods to prepare silver particles are toxic chemicals, such as hydrazine, sodium borohydride (NaBH4), dimethylformamide(DMF), polyvinyl pyrrolidone(PVP) [11], and these chemicals all have some potential risks to the environmental and human health.
In the present investigation, a clean, non-toxic, environmentally acceptable green chemistry synthesis procedure has been adopted.
The diffraction pattern was in agreement with the values of standard, pure, crystalline silver structure (JCPDS 4-0783).
The XRD pattern confirms that the structure of resultant silver nanoparticles is the face-centered cubic (FCC) crystal structure.

ETb microparticles present a compact aggregated structure with smoother surface and its size appears smaller than ETa.

According to the activated carbon hole structure and the benzene molecular diameter size relations, this time to adsorb the archery target adsorption efficiency contribution mainly by pore primarily [10].Along with the P continuation increase, the adsorption capacity increases the speed to start to drop until P/P0=1 when increases the speed close zero, the isothermal forms section of long platforms.

With the aim of searching for new bioactive indolizines against chronic inflammatory diseases and studying their structure-activity relationships, a general and straightforward methodology to rapidly prepare structurally diverse 3-aminoindolizine derivatives were introduced in this work.
Results and discussion 2.1 Chemistry In an effort to expand the poly-functionalized indolizines and study their structure-activity relationships (SAR), we studied the facial Pd-catalyzed intermolecular cycloisomerization strategy using propargyl amines as the key intermediates (Scheme 1).
The future studies on the structure-activity relationship of the indolizine derivatives and their anti-inflammatory activity were under way in our research group.

The physicochemical and structure properties of the samples were studied.
Meanwhile the crystal structure appeared intensively showing irregular sheet shape.
The crystallization structure of RS3 was a mixture of B–type and V–type.
The structure of RS3 was significantly different from structure of wheat starch, losing pasting properties of native starch.

For the gel structure, both ultrasonic and PVA affect to the Amide I and Amide II structure which lead to the gel characteristic used as a wound dressing in the future.
Since the Amide I/Amide II ratio can indicate about how much of the beta sheet structure and crystalline phase therefore the higher the ratio the stronger of the structure.

This scientific field investigates the relationship between the structure of materials at atomic or molecular scales and their macroscopic properties.
It incorporates elements of applied physics and chemistry.
A major breakthrough in the understanding of materials occurred in the late 19th century, when the American scientist Josiah Willard Gibbs demonstrated that the thermodynamic properties related to atomic structure in various phases are related to the physical properties of a material.

Fig. 1,(a, b) shows the change of the nodular form before milling to layer structure during milling process.
We suppose that the lamellar structure is due to the anisotropy of the elastic module in the iron monocrystal.
Continuous milling acts mostly on the structure of grain boundaries than on the size of the crystallites.
