Mode-beating spectra are investigated in long-perimeter (1.028 cm) monolithically integrated multiple-quantum-well semiconductor ring lasers. The beating line near 8 GHz is found to be split into two components. With increasing pumping current, a normal component shifts to lower frequencies, while an anomalous higher-frequency component shifts in the opposite direction. It is suggested the anomalous blue-shifting line results from power-induced perturbation of the refractive index in the vicinity of a strong mode. 相似文献

The determination of particle size by dynamic light scattering uses the Stokes–Einstein relation, which can break down for nanoscale objects. Here, we employ a molecular dynamics simulation of fully solvated 1–5 nm carbon nanoparticles for the refinement of the experimental data obtained for nanodiamonds in water by using dynamic light scattering. We performed molecular dynamics simulations in differently sized boxes and calculated nanoparticles diffusion coefficients using the velocity autocorrelation function and mean-square displacement. We found that the predictions of the Stokes–Einstein relation are accurate for nanoparticles larger than 3 nm while for smaller nanoparticles the diffusion coefficient should be corrected and different boundary conditions should be taken into account. 相似文献

A new approach to estimating the fault-tolerance of the parallel control computing systems relies on the mathematical model-based determination of the probability of successful completion in a given schedule time of an arbitrary set of interdependent jobs (tasks) with random times of job execution and asynchronous job redundancy. The estimates were determined both for the standard execution of a set of tasks and for the case of single malfunction (fault or failure) of any computing system processor detected at execution of any job from the set. The basic distinction of this approach lies in that here the numerical values of the reliability parameters (probabilities or intensities of faults or failures) of the computing resources are neither given nor used. 相似文献

Nanocomposites consisting of one-dimensional (1D) crystals of the cationic conductors CuI, CuBr and AgBr inside single-walled carbon nanotubes, mainly (n, 0), were obtained using the capillary technique. 1D crystal structure models were proposed based on the high resolution transmission electron microscopy performed on a FEI Titan 80-300 at 80 kV with aberration correction. According to the models and image simulations there are two modifications of 1D crystal: hexagonal close-packed bromine (iodine) anion sublattice (growth direction <001>) and 1D crystal cubic structure (growth direction <112>) compressed transversely to the nanotube (D(m) ~1.33 nm) axis. Tentatively this kind of 1D crystal can be considered as monoclinic. One modification of the anion sublattice reversibly transforms into the other inside the nanotube, probably initiated by electron beam heating. As demonstrated by micrographs, copper or silver cations can occupy octahedral positions or are statistically distributed across two tetrahedral positions. A 1DAgBr@SWNT (18, 0; 19, 0) pseudoperiodic 'lattice distortion' is revealed resulting from convolution of the nanotube wall function image with 1D cubic crystal function image. 相似文献

In crude oil-toluene solutions dynamic viscosity η and spin-spin relaxation time T2 were measured as functions of asphaltene concentration C in the range of 10-300 mg/l. The results were supplemented by studies of optical absorption. Extrema in the measured concentration dependencies are attributed to a transient predominance of specific asphaltene aggregates—from dimers to stacked molecular nanoclusters (MNCs) of four monomers. The strikingly non-ideal properties of solutions with C below 150-170 mg/l are attributed to the strong interactions between asphaltene species. At higher C the solution properties are evidently determined by the weaker interacting MNCs and the concentration effects are closer to those in ideal fluid mixtures. The observed re-entrant η(T2) behaviour in asphaltene solutions hypothetically has the same origin as in supercooled or demixing molecular systems, where anomalous structural and dynamical features are often explained by emerging heterogeneity due to transient spontaneous clustering. 相似文献

The response of the nonequilibrium phase T-ZrO2 to various physicochemical influences was studied by x-ray diffraction analysis. The results indicate a significant sensitivity of the T-ZrO2 M-ZrO2 phase transition to some of the influences: pressing at elevated temperatures (100–250°C) accelerates the formation of the equilibrium phase, whereas Al2O3 additions notably slow down the process (stabilize the metastable phaseT-ZrO2). Mechanochemical treatment and freezing at 77 K have no effect on the character of the phase transition. 相似文献
