Determination of chemical structure of the demulsifier and the defoaming agent.
Chemical analysis and FTIR analyses were applied to determine the structure of demulsifier named D1 and defoaming agent named F1.
Considering the functional groups, we got that structure of the major components of the demulsifier is a non-ionic demulsifier which is oil soluble and consists of alkyl phenolic resin polymerized with EO and PO. [4] The components structure of defoaming agents is fluorocarbon-graft-polysiloxane.[5] Determination of dehydration speed of demulsifiers.

Solar Cells from Thin Silicon Layers on AlN Zhijian Wan, Yong Huang, Houxing Zhang and Haifeng Li State Key Lab of New Ceramics and Fine Processing, Tsinghua University, Beijing 100084 Keywords: Ceramic substrate, Poly-silicon film, Rapid thermal chemistry vapor deposition Abstract.
The structure of polycrystalline silicon films was investigated.
Additionally a columnar crystalline structure can be observed.
The XRD analysis has revealed a preferential (up to 80%) (220) oriented structure.
The silicon film deposited by RTCVD on AlN ceramic substrate is compact and uniform and with a columnar crystalline structure.

It can be found that all the ceramics show pure perovskite structure suggesting that solid solution were formed.
However, there are few reports about preparing the BCZT ceramics sintered in different temperatures and effect of sintering temperature on structure and electric properties.
Thus the sintering temperature on the crystal structure of the ceramic has certain influence.
The results showed that the BCZT powderss is ABO3 type perovskite structure.

Three-dimensional holographic vector of atomic interaction field (3D-HoVAIF) is used to describe the chemical structures.
Quantitative structure-property relationship (QSPR) model for estimation subcooled liquid vapor pressures (log PL) of 212 PCDD/Fs seems reasonable, which is showed in many previous studies [1].
In QSPR study, the choice of structure descriptor plays a momentous role.
In this paper, Three-dimensional holographic vector of atomic interaction field (3D-HoVAIF), which is a new 3D descriptor proposed by Li and his co-workers[2], is chosen to describe the chemical structures of PCDD/Fs.
Calculation for 3D-HoVAIF descriptors of PCDD/Fs Original spatial structures of the 212 PCDD/Fs molecules are autogenerated by software Chemoffice 2004, and then optimized preliminarily using semi-empirical quantum chemistry soft MOPAC in Chem 3D at AM1 level (energy cut-off:0.001 kJ·mol-1).

Introduction: InAs/GaSb based type II and broken-gap quantum well (T2BGQW) has attracted intensive attentions in the past decades due to its unique subband structure.
In recent years, this unique QW structure has been applied as advanced optical devices such as uncooled infrared detectors[1], photovoltaic detectors[2], etc.
Recently, this structure has been considered to be the most promising candidate for the third generation detector[3].

No T0 or T1 structures were present in the 29Si NMR spectrum, indicating sufficient viscous sol to contain HBB T60(Fig 1A).
Three high-symmetry complete MSSOs, T8, T20 and T60 (see Fig. 3), were assigned (see Table 1).These predicted structures have a compliance between the experimental measurement value and the calculated molecular weight according to ion adducts (M+H+ or M+Na+ or M+K+)[9].
Further investigation will be conducted on this MP-HBB to separate it from multiple MSSO structures using a gel permeation column[10].
