In recent years, the development of efficient green chemistry methods for synthesis of metal nanoparticles has become a major focus of researchers.
The XRD observed with 2q degrees at 37.8, 44.0, 64.4 and 77.4 can be assigned to the (111), (200), (220), and (311) Bragg's reflections of the face-centered cubic crystalline structure of metallic nanoparticles, respectively.

Based on field water testing, water level monitoring, pumping test, as well as indoor leaching experiment, applying mathematical statistics, Pipers trilinear nomograph and PHREEQC chemistry simulation methods, saline water area of the town of Sungeng Jiyang was studied.
According to the results of X ray diffraction showed in Table 1, formation lithology was mainly fine sand and silt with multilayer structure vertically, also small thickness of single layer, and a plurality of layers of thin clay clip.
PHREEQC chemistry simulation shows that , in the alternate process of salt and fresh water, mineral deposition exists but halite and gypsum are still in dissolution.

Arising from the operation of equipment vibration will transfer to the building structure, no complete attenuation of vibration in the form of noise released into the outdoor space [2,3].
Secondly, room sound insulation effect is not obvious, the noise can also be spread through the building structure.
Material, component or structure to isolate the air borne noise, thereby obtaining a quiet environment called the sound insulation[6].

Introduction Dihydromyricetin(3,5,7,3’,4’,5’-hydroxyl-2,3-dihydrogenflavone,DMY),known as Ampelopsin, is a kind of flavonoid compound, which molecular structure is shown in Fig.1.
But the lipophilicity of DMY is poor because of its molecule structure holding multiple phenolic-hydroxyl groups , so in the lipid system, the application of DMY is not satisfactory[7].
The structures of obtained products were identified by the UV-visible spectrum, Infrared spectrogram,, H NMR.
But its lipophilicity is poor because of its molecule structure holding multiple phenolic -hydroxyl groups to limit its applications in lipid[9].

So developing an economic and efficient product, relationship between the transport properties and structure of the molecule is important and necessary.
Chain rotation is restricted while movement in structure is highly vibratory.
The structure is very dense and has very little voids around 0.2-10%.

The molecular structures and their abbreviations were shown in Fig. 1.
The structures and abbreviations of the final products were shown in Fig. 1, which were confirmed by 1H NMR and elemental analysis.
Chemical structures of the series of Schiff base compounds with aromatic spacer.
Based on the relative research reports [4-5], a multilayer film or three-dimensional (3D) structure could be suggested in these spreading films.
The present work may give some insight to design and character the relationship between the molecular structures and supramolecular aggregation of amphiphiles in organized molecular films.

Preparation of Co0.5Zn0.5Fe2O4 and Co0.5Mn0.5Fe2O4 Nano ferrites by Co-precipitation method ABDOLLAH JAVIDAN1,2, MIR HASSAN HOSSEINI2, S.L.SHAIFI1,2 1 Department of Chemistry, Imam Hossein University,Tehran, Iran. 2 Nano–research Center, Imam Hossein University,Tehran, Iran Abdollah.Javidan@gmail.com Keywords: Ferrite nanoparticles,Co-precipitation method, XRD.
The magnetic properties of spinel ferrites can be varied systematically by changing the identity of the divalent M2+ cations (M = Co, Mn,Ni,Zn,etc.) without changing the spinel crystal structures[5]. spinel-type structure of in ABCO4 have tetrahedral A sites and octahedral when B=C=Fe in ABCO4 will change to the AFe2O4 crystal structure.
Introduction a third metal in the structure will change the distrubation and changes the properties of the ferrospinels.
The observed diffraction lines were found to correspond to those of a standard manganese ferrite pattern, thereby indicating that the samples have spinel structure.

SC1 (NH4OH/H2O2/H2O-mixture), which constitutes the first step of RCA cleaning, is one of the most widely used wet chemistries for particle and organic contaminants removal.
The use of additional physical forces in the solutions, such as megasonic, must be sufficiently optimized to prevent damage to more fragile fine structures on the wafer.
In this work we studied the influence of oxide loss with respect to the particle and metal contamination removal, as well as the effect on fine structures by physical cleaning.
At the same time basic chemistry improves the nitride PRE compared with DIW [3], since the SC1 mist works to reduce the adhesion force by creating negative charges for both wafer and particles.
No damage was observed on 70-nm poly line structures, and >80% nitride particle removal efficiency was obtained under the condition of SC1 dispense, 0.05nm oxide loss and 60 NL/min of nitrogen flow in Nanospray.
