We have studied the voltage fluctuations of current-biased, micron-scale magnetic tunnel junctions. find that spectral power density is $1/f$-like at low frequencies and becomes frequency independent high frequencies. The frequency-independent background noise due to Johnson-Nyquist shot mechanisms. nature $1/f$ has its origin in two different In hysteresis loops this strongly field-dependent thermal magnetization both ``free'' ``fixed'' layers. attribute these thermally excited hopping...
Rare-earth-doped fluorochlorozirconate (FCZ) glass-ceramic materials have been developed as scintillators and their properties investigated a function of dopant level. The paper presents the relative scintillation efficiency in comparison to single-crystal cadmium tungstate, intensity x-ray energy, spatial resolution (modulation transfer function). Images obtained with FCZ scintillator tungstate are also presented. Comparison shows that image quality using glass ceramic is close from...
Abstract— The pattern of activity found in ventral roots removed at different times after seventh lumbar and first sacral cord injections [ 3 H]leucine gave evidence for fast slow phases axoplasmic flow. An intra‐axonic location was shown the flow by block downflow produced freezing a narrow region root, reduction on preinjection puromycin into radioautography roots. Separate mechanisms appear to be required account
The electrochemical reaction of FeSb2 with Na is reported for the first time. discharge (sodiation) potential profile characterized by a gentle slope centered at 0.25 V. During charge (Na removal) and subsequent discharge, main takes place near 0.7 V 0.4 V, respectively. reversible storage capacity amounts to 360 mA h g−1, which smaller than theoretical value 537 g−1. reaction, studied ex situ in X-ray diffraction, found proceed consumption crystalline form an amorphous phase. Upon further...
We report experimental studies to understand the reaction mechanism of intermetallic anode Cu2Sb with Na and demonstrate that it is capable retaining about 250 mAh g–1 over 200 cycles when using fluoroethylene carbonate additive. X-ray diffraction data indicate during first discharge leads formation crystalline Na3Sb via an intermediate amorphous phase. Upon desodiation reverts phase, which then recrystallizes into at full charge, indicating a high degree structural reversibility. The...
Abstract This study was conducted to investigate some fundamental fatigue testing variables as they apply the response characteristics of acrylic bone cement. Cyclic loading under load control at frequencies 1, 2, 5, 10, and 20 Hz in air room temperature. At a tensile stress range 0.3–20.0 MPa life increased linearly with logarithmic frequency. The effect conditioning saline both temperature 37°C similar levels frequency 10 were also examined. When compared dry temperature, resulted...
Objective: To define the kinematic motion patterns of canine cervical spine, with a particular emphasis on identifying differences between cranial (C 2 –C 4 ) and caudal 5 7 segments, to determine significance coupled motions (CM) in spine. Study Design: Cadaveric biomechanical study. Sample Population: Cervical spines 8 Foxhounds. Methods: Spinal specimens were considered free pathology based radiographic, computed tomography, magnetic resonance imaging examinations. All musculature was...
A series of hydrogenated diamondlike carbon films grown using plasma-enhanced chemical-vapor deposition is systematically studied as a function source gas composition transmission electron microscopy. The structure the examined at three distinct length scales. Both plan-view and cross-sectional studies are undertaken to reveal any large-scale inhomogeneities or anisotropy in films. degree medium-range order measured by performing fluctuation microscopy on specimens. Electron-energy-loss...
We found enhanced upconverted fluorescence in Nd3+-doped fluorozirconate glasses which were additionally doped with chlorine ions. Upon annealing between 240 and 290°C, hexagonal phase BaCl2 nanocrystals 20 180nm diameter formed the glass. During thermal processing, some of Nd3+ ions enter leading to additional splitting infrared spectra increased intensities. The optimum value was for 270°C sample where intensity is approximately a factor 60 stronger than one as-made
