The electronic structure near the band gap of the corundumlike Î± phase of Ga2O3 has been investigated by means of optical absorption and spectroscopic ellipsometry measurements in the ultraviolet (UV) range (400-190 nm). The band model is then employed to investigate the possible role of ethane as a source of thermal infrared opacity within the atmospheres of Jupiter and Saturn, and to interpret qualitatively observed brightness temperatures for Saturn.īand gap of corundumlike Î± -Ga2O3 determined by absorption and ellipsometry Employing this empirical profile, a simple expression is derived for the integrated band absorption, which is in excellent agreement with experimental values. It is shown that a Gaussian profile provides an empirical representation of the apparent spectral absorption coefficient. The intensity is found to be about 34 per sq cm per atm at STP, and this is significantly higher than previous estimates. Measurements of the absolute intensity and integrated band absorption have been performed for the nu sub 9 fundamental band of ethane. The nu sub 9 fundamental of ethane - Integrated intensity and band absorption measurements with application to the atmospheres of the major planets To our knowledge, this perfect absorption phenomenon is achieved for the first time in a designed metallic grating structure. Thus, when the phase resonance and the frequency tunable CM resonance occur together, transmission and reflection can be suppressed simultaneously, dual- band nearly perfect absorption with tunable frequencies is obtained. The grooves on the rear surface give rise to the phase resonance which not only suppresses the transmission but also reinforces the reflectance depression effect. The grooves inside the slits is to tune the frequency of the Cavity Mode(CM) resonance which enhances the transmission and suppresses the reflectance simultaneously. To fill this gap, in this paper, by adding subgrooves on the rear surface as well as inside the grating slits to a free-standing metallic grating, tunable dual- band perfect absorption is also obtained for the first time. However, to date, most of the perfect absorption effects achieved based on metamaterials are also available using an metallic grating except the tunable dual(multi)- band perfect absorption. Comparatively speaking, metallic grating is the preferred choice for the same absorption effect because it is structurally simpler and more convenient to fabricate. Traditional metallic gratings and novel metamaterials are two basic kinds of candidates for perfect absorption. Tunable dual- band nearly perfect absorption based on a compound metallic grating Based on the experimental results and the calculations by density functional theory, the chemical state of the S species and the formation of the S-dopant states in the band gap of Si are critical in determining the sub- band gap absorptance of hyperdoped Si samples.

VB-PES spectra evidently reveal that the S-dopants not only form an impurity band deep within the band gap, giving rise to the sub- band gap absorption, but also cause the insulator-to-metal transition in S-hyperdoped Si samples. The Si K-edge XANES spectra show that S hyperdoping in Si increases (decreased) the occupied (unoccupied) electronic density of states at/above the conduction- band-minimum. Principal Findings Glucose had a positive effect on both the motility (p â€‰2)]. To study the absorptive function of the bacillary band in relation to 6-NBDG, the oral uptake was minimised or excluded by sealing the oral cavity with glue and agarose. The absorptive function of the bacillary band in living worms was explored using a fluorescent glucose analogue (6-NBDG) and confocal microscopy. The viability of the worms was evaluated using a motility scale from 0 to 3, and the colorimetric assay Alamar Blue was utilised to measure the metabolic activity. Methodology We studied the dependency of adult Trichuris muris on glucose and/or amino acids for survival in vitro and the absorptive function of the bacillary band.

However, the exact function of the bacillary band is still unknown. may affect drug absorption and perhaps contribute to the low drug accumulation in the worm.

The bacillary band, a specialised morphological structure of Trichuris spp., as well as the unique partly intracellular habitat of adult Trichuris spp. infections in humans and animals is the variable but low efficacy of single-dose benzimidazoles currently used in mass drug administration programmes against human trichuriasis.
