The use of 1‐butyl‐3‐methylimidazolium hexafluorophosphate ionic liquid [C4mim][PF6] as additive in a Pb(II) plastic membrane electrode increased significantly the selectivity of the sensor. Atomic force microscopy and depth profiling X‐ray photoelectron spectroscopy were applied to investigate the compositional and morphological changes of the surface and bulk of the membrane during the conditioning process of the electrode. 相似文献

Monodisperse FePt nanoparticles with average size of 2.4?nm were successfully synthesized via chemical co-reduction of iron acetylacetonate, Fe(acac)3, and platinum acetylacetonate, Pt(acac)2, by 1,2-hexadecanediol as a reducing agent and oleic acid and oleyl amine as surfactant. Then using the seed mediated growth process smaller sized FePt nanoparticles are used as seeds for the growth of larger sized FePt particles and there is no specific limitation to achieve upper size range by this method. In this work, we could synthesize FePt nanoparticles up to 4.0?nm. Monodispersity with relatively narrow size distribution and having the same elemental composition with the atomic percentage of Fe x Pt100?x (x?=?63) are the main advantages of this method. As-made FePt nanoparticles have the chemical disordered face centered cubic structure with superparamagnetic behavior at room temperature. After annealing these particles become ferromagnetic with high magnetocrystalline anisotropy and their coercivity increases with increasing particle sizes and reaches a maximum value of 5,200?Oe for size of 46.5?nm 相似文献

Sliding observer for synchronization of fractional order chaotic systems with mismatched parameter 总被引:1,自引:0,他引:1

In this paper, we propose an observer-based fractional order chaotic synchronization scheme. Our method concerns fractional order chaotic systems in Brunovsky canonical form. Using sliding mode theory, we achieve synchronization of fractional order response with fractional order drive system using a classical Lyapunov function, and also by fractional order differentiation and integration, i.e. differintegration formulas, state synchronization proved to be established in a finite time. To demonstrate the efficiency of the proposed scheme, fractional order version of a well-known chaotic system; Arnodo-Coullet system is considered as illustrative examples. 相似文献

Relying on the quantum tunnelling concept and Maxwell–Boltzmann–Gibbs statistics, Gamow shows that the star-burning process happens at temperatures comparable to a critical value, called the Gamow temperature () and less than the prediction of the classical framework. In order to highlight the role of the equipartition theorem in the Gamow argument, a thermal length scale is defined, and then the effects of non-extensivity on the Gamow temperature have been investigated by focusing on the Tsallis and Kaniadakis statistics. The results attest that while the Gamow temperature decreases in the framework of Kaniadakis statistics, it can be bigger or smaller than when Tsallis statistics are employed. 相似文献

This article is devoted to the determination of numerical solutions for the two-dimensional time–spacefractional Schrödinger equation. To do this, the unknown parameters are obtained using the Laguerre wavelet approach. We discretize the problem by using this technique. Then, we solve the discretized nonlinear problem by means of a collocation method. The method was proven to give very accurate results. The given numerical examples support this claim. 相似文献
