We study the tunnel magnetoresistance (TMR) effect and magnetocrystalline anisotropy in a series of magnetic junctions (MTJs) with $L{1}_{1}$-ordered fcc ferromagnetic alloys MgO barrier along [111] direction. Considering (111)-oriented MTJs different $L{1}_{1}$ alloys, we calculate their TMR ratios anisotropies on basis first-principles calculations. The analysis shows that Co-based (CoNi, CoP...

The metal-assisted chemical etching (MACE) was used to synthesis silicon nanowires. The effect of etchant concentration, etching and chemical plating time and doping density on silicon nanowires length were investigated. It is held that the increasing of HF and H2O2 concentrations lead to etching rate increment and formation of wire-like structure. The results show that, the appropriate ratio o...

Sn02 nanowires with diameters of 30 — 200 nm have been synthesized by using carbothermalprocess via a thick film of tin dioxide and carbon powder precursor. The nanowires werecharacterized by X-ray power diffraction (XRD), scanning electron microscopy (SEM),transmission electron microscopy (TEM) and Selected Area Electron Diffraction (SAED).The gas sensing characteristic of nanowires toward eth...

A flexible CoNi@CNF electrochemical catalyst was developed using coaxial electrostatic spinning technology. The distribution and content of CoNi alloy nanoparticles on the surface carbon fibers were adjusted by regulating feed speed ratio outer inner axes spinning. results indicate that distributed fiber increased from 26.7 wt.% to 38.4 with an increase in axis. However, excessive precipitation...

OBJECTIVE To report mortality in babies enrolled on a community-based programme, Care of Next Infant Plus (CONI PLUS), which primarily supports parents anxious because of previous sudden unexpected death in infancy (SUDI) in their extended family or following an apparent life threatening event (ALTE) in their baby. DESIGN Prospective observational study from 1996 to 2010 in the UK. RESULTS ...

Leaflets of the tricuspid valve are provided by tendinous cords extending from the papillary muscles. The situation is complicated with the septal muscles, which generally occur in two groups, one as constant musculus coni arteriosi and the second as other variable septal muscles. We tested whether there is a variability in the provision of the tricuspid valve in different taxonomical groups of...
