The uniaxial stress changes the energy spacing at the band-edge states and the Fermi momenta, which reflects on the spectrum peak frequencies and the transition gaps, respectively. These optical characteristics are also influenced by the layer number. Besides, deformation shows some similar and different effects in comparison with electric and magnetic fields. These predicted optical properties can be verified by optical measurements. (C) 2010 American Institute of Physics. [doi:10.1063/1.3463390]“
“We presented a 34-year-old woman with blurred vision and inability to walk due to acute optic neuritis and transverse myelitis, neuromyelitis optica (Devic’s syndrome),

for an interesting presentation of this syndrome with proteinuria as the first manifestation of systemic lupus HKI272 erythematosus.”
“Nanosized Fe(OH)(2) was synthesized by a coprecipitation method. Peaks between 500 and 1250 cm(-1) in Fourier transform infrared (FTIR)

spectroscopy confirmed the presence of metal hydroxide stretching. X-ray diffraction showed the suppressed crystalline system of Fe(OH)(2)/aniline (ANT) due to the presence of a higher weight percentage of the dispersing agent, ANT. Thermogravimetric analysis implied that 75.5 wt % of residue remained up to 800 degrees C. High resolution transmission electron microscope (HRTEM) analysis of Fe(OH)(2)/ANI revealed that its size ranged from A-769662 ic50 10 to 50 nm with a rodlike morphology. Scanning electron microscopy implied that pristine Fe(OH)(2) had a nanotriangular platelet morphology, and a higher weight percentage of dispersing agent intercalated with Fe(OH)(2) had a spheroid Silmitasertib order with an agglomerated structure. The (UV-visible) spectrum implied the presence of Fe(2+) ions at 326 nm and the existence of an amino group intercalated with Fe(OH)(2) showed a sharp peak at 195 nm, the intensity of which increased with increasing intercalated dispersing agent weight percentage. Photoluminescence

showed that ANI-intercalated Fe(OH)(2) showed a lesser intensity than the pristine Fe(OH)(2). (C) 2010 Wiley Periodicals, Inc. J Appl Polym Sci 118: 1728-1737, 2010″
“We have studied the scattering process of AlGaAs/GaAs two-dimensional electron gas with the nearby embedded GaSb/GaAs type-II quantum dots (QDs) at low temperature. Quantum Hall effect and Shubnikov-de Haas oscillation were performed to measure the electron density n(2D), the transport lifetime tau(t) and the quantum lifetime tau(q) under various biased gate voltage. By comparing measured results of QDs sample with that of reference sample without embedded QDs, mobilities (transport mobility mu(t) and quantum mobility mu(q)) dominated by GaSb QDs scattering were extracted as functions of n(2D). It was found that the ratios of tau(t) to tau(q) were varying within the range of 1-4, implying the scattering mechanism belonging to the sort of short-range interaction.
