We report a facile and scalable approach to synthesize single-walled carbon nanotubes (SWNTs) with selected diameter distribution by applying a magnetic field perpendicular to the electric field in the arc plasma region. It is found that this magnetic field-induced diameter-selectivity strategy enables the control of the SWNTs with different diameter distributions in different regions, and the ...
BACKGROUND AND PURPOSE Intracerebral hemorrhage volume (ICHV) as a percentage of total brain volume (TBV) is a strong predictor of outcome in childhood intracerebral hemorrhage with ICHV/TBV >2% associated with functional impairment. We aimed to determine whether easily performed approximations of intracerebral hemorrhage and brain volume can accurately and reliably stratify intracerebral hemor...

We demonstrate an all-fiber add-drop filter composed of a microfiber knot (working as a resonator) and a fiber taper (working as a dropping fiber). The dropping taper can be either parallel or perpendicular to the input port of the filter. A quality factor (Q factor) of 13,000 is obtained from a parallel-coupling 308 microm diameter microknot add-drop filter with a free spectral range (FSR) of ...
In this study, the abundance and biomass of soil macrofauna were investigated in natural forests of tamarisk and Euphrates poplar in riparian forests of Maroon River in Khuzestan province. Soil macrofauna were collected using 175 sampling plots 50 meter distance from each other on 21 parallel lines with 100 meters distance from each other and perpendicular to the river. Soil macrofauna sampling...
in solvo-hydrothermal method, xrd pattern was indicated presence of intermediate of ammonium octatmolybdate and ammonium tetramolybdate, which were changed to stble phase of ?-moo3 annealing. sem images were indicated nanoparticle with semispheical morphology and tem image was demonstrated nanoparticles with a diameter size of 25nm. also in impregnate method. the xrd pattern was shown high crys...
introduction: knowledge of the presence of the alveolar antral artery in the lateral maxillary sinus wall is essential for surgeons who operate in this region. the purpose of this study was to investigate the correlation between alveolar antral artery diameter and lateral maxillary bony wall thickness in dentate patients. materials and methods: thirty five cone-beam computed tomography (cbct)...
Existing techniques for characterization of longitudinal recording media using remanence measurements are extended to perpendicular media, in particular to Alumite, and correction for demagnetizing fields is taken into account. It is found that these techniques have limited value because of the sensitivity of the analysis to the correction factor used. Measurement of the recoil lines is investi...
The phenomenon of exchange bias plays an important role in the development of spin electronic devices. Recently, the study of exchanged-biased systems with perpendicular anisotropy has attracted a lot of interest since the AF spin distribution at the interfaces can be probed. However only studies on non-patterned polycrystalline structures have been reported [1,2]. Here, a study of exchange bia...
