A simply and reproducible way is proposed to significantly suppress the nucleation density of graphene on copper foil during chemical vapor deposition process. By inserting a into tube with one close end, foils can be reduced by more than five orders magnitude an ultra-low ~10 nucleus/cm2 has been achieved. The structural analyses demonstrate that single crystal monolayer lateral size 1.9 mm grown under optimized growth condition. electrical transport studies show mobility such around 2400 cm2/Vs.
Quasi-spherical molecules have recently been developed as promising building blocks for constructing high-performance molecular ferroelectrics. However, although the modification of spherical into quasi-spherical ones can efficiently lower crystal symmetry, it is still a challenge to precisely arouse low-symmetric polar structure. Here, by introducing directional hydrogen-bonding interactions in modification, we successfully reduced cubic centrosymmetric Pm3̅m space group...
This study describes a novel meshless technique for solving one of common problem within cell biology, computer graphics, image processing and fluid flow. The diffusion mechanism has extremely depended on the properties structure. present paper studies why processes not following integer-order differential equations, method solving. surface numerically. variable- order time fractional equation (VO-TFDE) is developed along with sense Caputo derivative (0<α(t)<1). An efficient accurate...
This study mainly investigates new techniques for obtaining numerical solutions of time-fractional diffusion equations. The fractional derivative term is represented in the Lagrange operational sense. First, we describe temporal direction considered model using Legendre orthogonal polynomials. Moreover, to archive a full discretization approach type nonlocal method has been applied that known as peridynamic differential operator (PDDO). PDDO based on concept (PD) interactions by proposing PD...
It is known from the theory of group representations that, in principle, a tensor any finite order can be decomposed into sum irreducible tensors. This paper develops simple and effective recursive method to realize such decompositions both two-and three-dimensional spaces. Particularly, derived have mutually orthogonal base elements. Quite few application examples are given for generic various physical tensors orders up six.
The third-order linear piezoelectricity tensor seems to be simpler than the fourth-order elasticity one, yet its total number of symmetry types is larger latter and exact still inconclusive. In this paper, by means irreducible decomposition multipole representation corresponding four deviators, we conclude that there are 15 piezoelectric types, thus further establish their characteristic web tree. By virtue notion mirror antisymmetry, define three indicators with respect two Euler angles...
This paper presents a closed-form solution for the arbitrary polygonal inclusion problem with polynomial eigenstrains of order in an anisotropic magneto-electro-elastic full plane. The additional displacements or eigendisplacements, instead eigenstrains, are assumed to be general terms M+N. By virtue extended Stroh formulism, induced fields expressed group basic functions which involve boundary integrals domain. For special case inclusions, carried out explicitly, and their averages over...
In this paper, a meshless local radial point interpolation method (RPIM) is proposed for the thermoelastic analysis of functionally graded materials (FGMs) under thermal shocks. The properties such are temperature-dependent varying and change gradually through thickness based on Mori–Tanaka scheme volume fraction power law distribution (Appendix A). characterization visualization FGMs prescribed temperature gradient or heat flux then detailed. does not need any background cell-based...

The cable equation plays a prominent role in biological neuron models, for instance, spiking models and electrophysiology. Thus, the current investigation scrutinizes 2D time nonlinear multi-term fractional equation. By adopting valid meshfree technique, time-fractional equations (NM-TTFCEs) that consist of government their boundary conditions are transformed into value problems. For this purpose, finite difference method is derived temporal discretization such considered NM-TTFCEs can be...
