Abstract

The algorithm of Fredholm first kind integral equation solution which are used in electro-optics and dynamic light scattering is considered. The presented algorithm, unlike other algorithms aimed at solving the same problem, uses the peculiarities of the kernels of integral equations by applying additional constraints to the solution using specifically constructed penalty functions. This makes the precision of the solution higher for functions of one argument and allows to reliably solve integral equations with the solution as a function of two arguments. [ABSTRACT FROM AUTHOR]

Abstract

Results of an electrooptical study of a water solution of carbon nanotubes obtained using the catalytic method are presented. It is shown that nanotubes, which anisotropically absorb light, are oriented in an electric field and create a pronounced linear electric dichroism due to light absorption, rather than light scattering (as in the case of colloids with particles with sizes close to that of nanotubes). An analysis of the relaxation dependences of the electric dichroism shows that nanotubes deform, which are oriented in the electric field; in this case, the deformation sublinearly depends on the field amplitude and reaches a limiting value. The relaxation dependence of the field-induced dichroism agrees with the autocorrelation function of depolarized light scattered perpendicular to the incident light flux. [ABSTRACT FROM AUTHOR]
