N Sergueev,D Roubtsov,Hong Guo - 《Physical Review Letters》 被引量: 110发表: 2005年 Electron-phonon matrix elements in single-wall carbon nanotubes We have developed the electron-phonon matrix element in single-wall carbon nanotubes by using the extended tight-binding model based on density ...
Numerous researchers have succeeded in forming Ti-based amorphous alloys with different element combinations such as Ti–Ni–Cu, Ti–Ni–Cu–Al, Ti–Zr–Ni–Cu–Al, Ti–Ni–Cu–Sn, and Ti–Ni–Cu–Si–B. These alloys exhibit a large supercooled liquid region up to 90 K and relatively ...
An influence of normal stresses acting on the shear plane is evidenced by: (i) the fracture angle (<45°) and (ii) finite-element simulations of nanoindentation curves, which require the use of a specific yield criterion, sensitive to local normal stresses acting on the shear plane, to ...
Thus, given the absence of this metallic element, as observed in our patient group, one cannot exclude its possible role in multiple sclerosis, since this is a disease characterized by the process of demyelination. However, in the control group this metallic element may be responsible for the ...
Investigation into the dynamic behaviour of rolling element bearings is motivated by the urge to reduce vibrations in rolling bearing applications. The dyn... YH Wijnant,JA Wensing,GC Nijen - 《Journal of Sound & Vibration》 被引量: 107发表: 1999年 Decay Rates of Interactive Hyperbolic-Parabol...
Figures 5 and 6 illustrate the effects of element content on the GFAs of the binary Nb-Al and ternary Ni-Nb-Al alloy systems, respectively. The amorphous phase of the binary Nb-Al alloy formed in the composition range 10–90 at.% Nb (Figure 5), reasonably consistent with the GFR of ...
The following points are noticed: iron is the most abundant metallic element in the leachate. Its concentration is found to be from 0.4 to 4.0 mg l1. Other metallic elements such as Cr, Ni, Mn, Cu, Co, Al and Zn exist as trace amounts (from 0.1 to 1.0 mg l1). Heavy metals such...
6. Finite element analysis The quasi-static compressive collapse of the origami specimens was simulated using the commercial finite element package Abaqus Standard. The aim of this numerical study is to interrogate the accuracy of finite element predictions of the collapse response for these SLM-manufa...
Seals are a crucial machine element used to confine a high pressure fluid to some given volume. Due to the interfacial surface roughness most seals exhibit leakage [1, 2]. To minimize the leakage, seals are usually made from a soft material, such as rubber (with an elastic modulus of orde...
A three dimensional volume element (32 × 32 × 14.25 nm3) was discretized by a proper grid, and extended laterally by periodic boundary conditions. Figure 4 Micromagnetic simulation of elastically driven spin-wave resonance in a magneto-elastic capping layer (CoFeB). (a) Thickness...
