molecular orientation
1.The molecular orientation of crystalline and liqtiid crystalline states of poly(MMA-co-BMA)and ChN mixtures have been sttidied by X-ray diffraction.
2.Utilizing the smectic C* continuum theory, the polymer network energy model and FLC molecular orientation model which were designed, the "V"shape E-O curve in the PNSFLCDs cell has been studied theoretically.
3.Significant changes in crystalline structure and molecular orientation were observed after the extrusion. The degree of crystalline and melting point increased and the size of the crystallites decreased. The tensile strength of i-PP was increased from 17.13 MPa to 59.38 MPa via ICAE processing.
4.Ultrahigh molecular weight polyethylene(UHMWPE) fiber, which is a linear chain structure of high crystallization and high orientation, is the third generation of high-performance fibers appearing following carbon fibers, Kevlar fibers.
5.Surface-enhanced Raman Scattering(SERS) technology is widely used as an analytical tool to investigate molecular structure and interaction between molecules and metal surface resulting in strongly increased Raman signals and fluorescence quenching The use of SERS for the research of the permutation orientation and the structure between the interface and the molecules such as the DNA and BSA is meaningful for understanding the living vitality course.
6.Suitable polycrystalline ZnS x Se 1- x film with (111) preferential growth orientation that provided a good matching with the requirements of LCLV were deposited on ITO coated glass by molecular beam epitaxy (MBE).
7.TATB crystal structure at high pressure is investigated by CASTEP in Material Studio, and the results show that (1) TATB crystal cell mainly changes on c-axis orientation, and the energetic band structure of crystal and TATB molecular structure change a little when the pressure changes from 0.1GPa to 10GPa.
8.In the present study we used conventional CoMFA and introduced four routines of modified CoMFA, cross-validated R2-guided regional selection ( q2-GRS), all-orientation search (AOS), all-placement search (APS) and comparative molecular similarity indices analysis (CoMSIA) , to investigate a set of 18 pinusolide and its derivatives as a kind of newly discovered platelet activating factor (PAF) antagonist.
