FePt has a potential application in high-density recording medium owing to the strong uniaxial magnetocrystalline anisotropy of its L10-ordered phase, which suppresses superparamagnetism in small particles. However, in most cases, the as-prepared samples are completely disordered A1 phase (face-centered cubic) and have no uniaxial anisotropy. The subsequent annealing for ordering is usually subjected...
Chalcogenide phase-change materials (PCMs) are technologically important since they are capable of undergoing fast and reversible transitions between the amorphous and crystalline phase. 1 The two phases have markedly different resistivity, which makes them currently exploited in non-volatile memory technology. In order to enable the multilevel memory in phase-change storage technology, spin is injected...
The hydroelectric generating set (HGS) is the machine that transform the water energy to power. The vertical structure is more common which is applied in large and medium-sized system. Because of great bulk, the rotating parts including generator's rotor, macroaxis, turbine runner and spiral case are great heavy. In addition, water flow impulsing the runner will produce a down force named axial hydro-thrust...
With the rapid developments of electronic packaging, there is an increasing demand on high performance isotropic conductive adhesives (ICAs). However, the traditional ICAs are brittle, sensitive for crack formation and delamination, which is one of the major drawbacks that limits their use in a wide range of applications. Therefore great efforts have been made to make conductive adhesives more flexible...
In this paper, a method of fabricating active CMOS-MEMS AFM-like conductive probes with nanometer-sized probe tips for Tip-directed Field-emission Assisted Nanofabrication (TFAN) is reported. We envision an approach using tip-directed chemical vapor deposition (CVD) for the deposition of Si nanowires (SNWs), using field-emitted electrons to locally crack adsorbed precursors (silane/disilane) through...
