Nonlinear fracture toughness measurement and crack propagation resistance of functionalized graphene multilayers

Science Advances, 2018
Functionalized graphene multilayer is tougher than graphene. Despite promising applications of two-dimensional (2D) materials, one major concern is their propensity to fail in a brittle manner, which results in a low fracture toughness causing ...

Background Pressure Induced Structural and Chemical Change in NiV/B4C Multilayers Prepared by Magnetron Sputtering

Frontiers in Physics, 2022
NiV/B4C multilayers with a small d-spacing are suitable for multilayer monochromator working at a photon energy region from 5 to 8 keV, or photon energy region from 10 to 100 keV.

Different steady states for spin currents in noncollinear multilayers

, 2004
We find there are at least two different steady states for transport across noncollinear magnetic multilayers. In the conventional one there is a discontinuity in the spin current across the interfaces which has been identified as the source of current ...

Vectorlike representation of multilayers [PDF]

Journal of the Optical Society of America A, 2004
We resort to the concept of turns to provide a geometrical representation of the action of any lossless multilayer, which can be considered as the analogous in the unit disk to the sliding vectors in Euclidean geometry. This construction clearly shows the peculiar effects arising in the composition of multilayers.

Research on Preparation of Multilayers by the Multiple Jet Electrodeposition

International Journal of Electrochemical Science, 2014
The preparation of multilayers by a novel multiple jet electrodeposition (MJED) technology with realtime polishing for deposit surface was studied. The microstructure and microhardness of Ni-Cu multilayers produced by MJED with and without polishing were

Magnetization in quasiperiodic magnetic multilayers with biquadratic exchange coupling

, 2001
A theoretical study of the magnetization curves of quasiperiodic magnetic multilayers is presented. We consider structures composed by ferromagnetic films (Fe) with interfilm exchange coupling provided by intervening nonferromagnetic layers (Cr).

Optimization of thermochromic VO2 based structures with tunable thermal emissivity [PDF]

, 2012
In this paper, we design and simulate VO2/metal multilayers to obtain a large tunability of the thermal emissivity of infrared (IR) filters in the typical mid wave IR window of many infrared cameras. The multilayer structure is optimized to realise a low

Multilayer Injection Molding

International Polymer Processing, 1991
Abstract Visualization of the fountain flow in a piston driven non-Newtonian flow is studied by means of experiments and numerical computation. The result will be applied to the multilayer injection molding technique, where an accumulator is used, to store the polymer melt.
