Temperature and concentration dependence of diffusion coefficient in dilute solutions*
Temperature and molecular weight dependence of k o in D(C)=D(O)[1 +CkD], where D(C) is the diffusion coefficient for the density fluctuations in a dilute polymer solution, is investigated by first expressing D(C) as a function of the static structure factor S(q,C) within the framework of the Kirkwood-Riseman theory. The continuous transition of k D from negative values under theta conditions to...
متن کاملSpin Diffusion gd Orientation Dependence of Deuterium Tl in Solids
The study of spin diffusion in solids has been of recent interest. Spin diffusion occurs by flip-flop cross-relaxation due to the S$Sj_ + S!Sj, term of the dipolar couplings among the spins (I). When a large inhomogeneous interaction also exists for the S spin system, then the flip-flop transition may not conserve energy, i.e., the resonances of the coupled spins do not overlap and are separate...
متن کاملDiffusion measurement in ferrous infused gel dosimeters
Background: The compositions of Ferrous sulphate, Agarose and Xylenol orange dye (FAX) and Ferrous sulphate, Gelatin and Xylenol orange dye (FGX) in solution of distilled water and sulphuric acid are two tissue-equivalent gel dosimeters. Ionizing radiation causes oxidation of Fe2+ ion to Fe3+ ions which diffuse through the gel matrix and blur the image of absorbed dose over a period of hours af...
متن کاملDetermination of the diffusion coefficient of hydrogen ion in hydrogels.
The role of diffusion in chemical pattern formation has been widely studied due to the great diversity of patterns emerging in reaction-diffusion systems, particularly in H+-autocatalytic reactions where hydrogels are applied to avoid convection. A custom-made conductometric cell is designed to measure the effective diffusion coefficient of a pair of strong electrolytes containing sodium ions o...
متن کاملCharge transport in DNA: dependence of diffusion coefficient on temperature and electron-phonon coupling constant.
The diffusion coefficient is calculated for a charge propagating along a double-stranded DNA, while it interacts with the nonlinear fluctuational openings of base pairs. The latter structural dynamics of DNA is described by the Peyrard-Bishop-Dauxois model [T. Dauxois, M. Peyrard, and A. R. Bishop, Phys Rev. E 47 R44 (1993)], which represents essential anharmonicities of base-pair stretchings. ...
