We present experimental data and a theoretical interpretation of the conductance near the metal-insulator transition in thin ferromagnetic Gd films of thickness b ≈ 2-10  nm. A large phase relaxation rate caused by scattering of quasiparticles off spin-wave excitations renders the dephasing length L(ϕ) ≲ b in the range of sheet resistances considered, so that the effective dimension is d = 3. T...

A highly conductive metallic gas that is quantum mechanically confined at a solid-state interface an ideal platform to explore nontrivial electronic states are otherwise inaccessible in bulk materials. Although two-dimensional electron (2DEG) has been realized conventional semiconductor interfaces, examples of hole (2DHG), which the counter analogue 2DEG, still limited. Here, we report observat...

We study mixing in a thermohaline staircase by means of direct numerical simulations (DNS). A single saltfingering layer is modeled as a diffusively unstable shear layer of hyperbolic tangent form. Our main interest is the influence of shear, and we focus on what we call the “moderate shear” case. This is the regime where shear is strong enough to produce Kelvin-Helmholtz (KH) instability, but ...

[1] The ice sheet–ice shelf transition zone plays an important role in controlling marine ice sheet dynamics, as it determines the rate at which ice flows out of the grounded part of the ice sheet. Together with accumulation, this outflow is the main control on the mass balance of the grounded sheet. In this paper, we verify the results of a boundary layer theory for ice flux in the transition ...

this paper addresses the combined effects of couple stresses, thermal radiation, viscous dissipation and slip condition on a free convective flow of a couple stress fluid induced by a vertical stretching sheet. the cogley- vincenti-gilles equilibrium model is employed to include the effects of thermal radiation in the study. the governing boundary layer equations are transformed into a system o...

The title coordination polymer, {[Cd(C8H4O4)(C14H14N4)]·C3H7NO} n , was synthesized by solvothermal reaction of metallic cadmium with the semi-rigid neutral ligand 1,4-bis-[(1H-imidazol-1-yl)meth-yl]benzene (bix) and the V-shaped benzene-1,3-di-carb-oxy-lic acid (m-H2bdc). The structure exhibits a pseudo-C-centring which is almost fulfilled by the polymeric metal complex but not by the solvent ...

This paper presents the coating thickness effect on the stress distribution of a coated cylinder head. A typical thermal barrier coating was applied on a diesel engine cylinder head. Thus, the residual stress which occurred during the plasma thermal spraying was also considered. The coating system consisted of two layers a metallic bond coat and a ceramic top coat. The bond coat thickness is co...

Metasurface have recently generated much interest due to its strong manipulation of electromagnetic wave and its easy fabrication compared to bulky metamaterial. Here, we propose the design of a multi-spectral metasurface that can achieve beam deflection and broadband diffusion simultaneously at two different frequency bands. The metasurface is composed of two-layered metallic patterns backed b...
