Oriented Polymers : A Transfer Matrix Calculation
نویسنده
چکیده
Based on transfer matrix techniques and nite size scaling, we study the oriented polymer (self-avoiding walk) with nearest neighbor interaction. In the repulsive regime, various critical exponents are computed and compared with exact values predicted recently. The polymer is also found to undergo a spiral transition for suciently strong attractive interaction. The fractal dimension of the polymer is computed in the repulsive, attractive regimes and at the spiral transition point. The later is found to be dierent from that at the collapse transition of ordinary self-avoiding walk. through the SRC program of SNU-CTP, and the Ministry of Education.

Investigation of Capsulated Epoxy and DCPD in Epoxy Based Self-healing Composites - DFT Calculation and Experimental Analysis
Epoxy and dicyclopentadien (DCPD) are two common healing agents, which are introduced into epoxy matrix through encapsulation in order to prepare self-healing composites. In a comparative study, the compatibility of healing agents and epoxy matrix is investigated through experimental tests and DFT calculations. The interaction energy is considered to be the determinative parameter in DFT calcul...
متن کاملControl of energy transfer in oriented conjugated polymer-mesoporous silica composites
Nanoscale architecture was used to control energy transfer in semiconducting polymers embedded in the channels of oriented, hexagonal nanoporous silica. Polarized femtosecond spectroscopies show that excitations migrate unidirectionally from aggregated, randomly oriented polymer segments outside the pores to isolated, aligned polymer chains within the pores. Energy migration along the conjugate...
متن کاملPolarized Bremsstrahlung in the Equivalent Photon Method
An economic technique for calculation of polarized bremsstrahlung process is proposed, assuming typical atomic momentum transfer q ≪ m. The adopted approach is based on the natural reduction of the matrix element to the form V γ + A5γ . Polarization distribution in the fully differential cross-section is analyzed. It is found that at a given momentum transfer to the atom polarization in the pla...

It is very complicated to calculate the secondorder aberrations of complex analyser systems and mistakes are liable to be made. Even if the matrix method is used the tediousness of the calculation is not altered. The usefulness of the matrix representation comes from the fact that the over-all transfer matrix of the total system is easily written as a product of the transfer matrices of various...
متن کاملModeling and Predicting the Stress Relaxation of Composites with Short and Randomly Oriented Fibers
The addition of short fibers has been experimentally observed to slow the stress relaxation of viscoelastic polymers, producing a change in the relaxation time constant. Our recent study attributed this effect of fibers on stress relaxation behavior to the interfacial shear stress transfer at the fiber-matrix interface. This model explained the effect of fiber addition on stress relaxation with...
