Results were consistent with a microstructural model in which birefringence depends on both the overall degree of molecular orientation and the extent to which crystalline reinforcement is present. This component of birefringence increase is temporary and recoverable. Tadashi Inoue, Shozo Kuwada, Deug-Soo Ryu, Kunihiro Osaki. Find more information about Crossref citation counts. The birefringence image on the left side of Fig. Both Raman peak shift and phase shift of birefringence images show a similar contrast pattern, indicating a good visualization of an inner stress in the diamond crystal. Giovanni Ianniruberto, Giuseppe Marrucci. Birefringence is the optical property of a material having a refractive index that depends on the polarization and propagation direction of light.

Oosterlinck, C. Clasen, E. van Ruymbeke. In amorphous materials, the refractive index for light polarized along an axis varies proportionally to both the linear stress in that axis and the transverse stress perpendicular to that axis. The phase difference between the transmitted s and p polarization depends on the angle of incidence and the incident polarization direction. mode. It is based on coupled equations (cf. [27]. In lieu of an abstract, this is the article's first page. Side Chain Length Dependence on Dynamical Stiffness of Main Chain. The birefringence was introduced into the materials by loading in uniaxial compression, and the decay of birefringence with time was measured using a … Effect of Hydrostatic Pressure Upon the Relaxation of Birefringence in Amorphous Solids J Res Natl Bur Stand A Phys Chem. Information about how to use the RightsLink permission system can be found at Viscoelastic Properties of Unentangled Multicyclic Polystyrenes. During processing the polymer experiences a lot of stress which could orient the molecular chains in undesirable manner inducing stress. Chunggi Baig, Brian J. Edwards, David J. Keffer.

Malomed, in Progress in Optics, 2002. When the gas laser is used as excitation source, plasma line is able to use as stable reference data for the calibration. A water-soluble crystallisation inhibitor (another of Nature’s lessons – see section 10.2.4) could be incorporated in protein solution that is spun at satisfactory industrial rates into a coagulating medium.

The Rouse–Mooney model for coherent quasielastic neutron scatterings of single chains well entangled in polymer melts. Equation (5.11) simply states the unitary condition for the Jones matrix M(ω). Linear polymer viscoelasticity. In the latter case, spinning and drawing occur consecutively, while in the former case these two processes occur simultaneously.

Tadashi Inoue,, Hidenori Kadoya, and. Molecular Structure, Chain Dimensions, and Linear Rheology of Poly(4-vinylbiphenyl). 10.9. Spinning and drawing therefore occur in series during the manufacture of synthetic fibres (Figure 10.9b), and it is apparent that the processing conditions used to optimise molecular order and mechanical properties in typical synthetic polymer fibres may not be similarly applicable in the context of silk-like polymers. Yuya Doi, Atsushi Matsumoto, Tadashi Inoue, Takuro Iwamoto, Atsushi Takano, Yushu Matsushita, Yoshiaki Takahashi, Hiroshi Watanabe. The phase shift ±12ΩΔω has the physical interpretation of the pulse delay. The crystallinity alone is a poor indicator of mechanical properties.

Nonlinear Elongational Rheology of Unentangled Polystyrene and Poly(p-tert-butylstyrene) Melts. (153) shows that in this case the variable y is driven at the frequency 1, and, in turn, it resonantly drives the variable W through eq. Viscoelastic Properties of Tightly Entangled Semiflexible Polymer Solutions. Takumi Kojo, Akihiro Tagaya, Yasuhiro Koike. When discussing the fiber birefringence property in Section 5.2.1, we assumed that the polarization eigen axis is invariant throughout a fiber.

Typically polycarbonate has a vertical birefringence of about 5 × 10‒4 (fig. James Carriere, ... Robert Anderson, in Progress in Optics, 2000. I. (5.11) over ω, it is easy to show that, Namely, D is a Hermitian matrix. 4.1.14 is a comparison of the XRT image and birefringence image observed in same area of type-Ib diamond. Chang Liu, Peiru Liu, Quan Chen, Binyang Du, Zuowei Wang. In order to derive equations for internal oscillations of the vector soliton, the following ansatz is adopted (cf. In order to realize how the resonances predicted by considering small internal vibrations of the vector soliton manifest themselves, the system of equations (153)–(154) was simulated numerically.
