TL;DR: The results of the calculation of mean values of positron lifetimes for the investigated glasses showed the existence of a long-living component on the positron annihilation lifetime spectra, and the size and fraction of free volume reaches the biggest value for the fused silica glass.

01 Jan 2013TL;DR: The space-time fractional heat conduction equation with the Caputo time fractional derivative and the Riesz fractional Laplace operator is investigated and the fundamental solutions to the Cauchy and source problems as well as associated thermal stresses are found in the case of spherical symmetry.
Abstract: The space-time fractional heat conduction equation with the Caputo time fractional derivative and the Riesz fractional Laplace operator is investigated. The fundamental solutions to the Cauchy and source problems as well as associated thermal stresses are found in the case of spherical symmetry. The numerical results for temperature and stresses are presented graphically for various orders of space and time derivatives.

TL;DR: A comparison of experimental data and theoretically evaluated results shows that for the photoinduced first-order nonlinear optical effect the dominant contribution is an amorphous-like structural component, unlike the transport properties, where the crucial role is played by the nanointerface region.
Abstract: Photoinduced second-order nonlinear optical effects, particularly optical second harmonic generation (SHG) of N-phenyls with different numbers of aromatic rings deposited on glass substrates were studied. As a fundamental beam, a 5-ps pulsed Nd:YAG laser was used. Quantum chemical time-dependent density functional theory (TDDFT) simulations of the nonlinear optical properties were performed. The first-order hyperpolar-izabilities of isolated molecules were calculated, under the influence of a polarized pumping beam, to evaluate the role played by the nanointerfaces separating the microcrystallites and the amorphous environment. Consideration was performed within a framework of steady-state Langevin order parameters for amorphous-like films. A strong dependence of the photoinduced SHG versus the number of aromatic rings determining the degree of film crystallinity was shown. A comparison of experimental data and theoretically evaluated results shows that for the photoinduced first-order nonlinear optical effect the dominant contribution is an amorphous-like structural component, unlike the transport properties, where the crucial role is played by the nanointerface region. This may reflect a specific feature of the multiphoton processes in such types of nanointerfaces because of nanoconfined effects.
