“…The data from SH and LH were extracted using the full slit extraction method of a script version of IRS data analysis package SMART (Higdon et al 2004) from the median of the combined images. The 1-dimensional spectra were flux calibrated by multiplying by a relative spectral response function (RSRF), which was created from the IRS standard star, ξ Dra, for which accurate templates were available (Cohen et al 2003;Sloan et al 2007). As a final cosmetic step the ends of each order where the noise increases significantly were manually clipped.…”

We present a study of elemental abundances in a sample of thirteen Blue Compact Dwarf (BCD) galaxies, using the ∼10-37µm high resolution spectra obtained with Spitzer/IRS. We derive the abundances of neon and sulfur for our sample using the infrared fine-structure lines probing regions which may be obscured by dust in the optical and compare our results with similar infrared studies of starburst galaxies from ISO. We find a good correlation between the neon and sulfur abundances, though sulfur is under-abundant relative to neon with respect to the solar value. A comparison of the elemental abundances (neon, sulfur) measured from the infrared data with those derived from the optical (neon, sulfur, oxygen) studies reveals a good overall agreement for sulfur, while the infrared derived neon abundances are slightly higher than the optical values. This indicates that either the metallicities of dust enshrouded regions in BCDs are similar to the optically accessible regions, or that if they are different they do not contribute substantially to the total infrared emission of the host galaxy.

“…15−18 Similarly, double-walled CNTs (DWCNTs) also can be synthesized using carbon nanopeapods as starting materials, where the inner CNT was formed by C 60 's coalescence under electron beam irradiation. 19,20 It is thus expected that a GNR encapsulated inside of a DWCNT is feasible by using the same experimental procedures. The additional CNT in the DWCNT compared to that for the SWCNT provides extra space for charge (re)distribution in the composite system, which may produce electronic properties that are suitable for designing new functionalities in applications.…”

Recent synthesis of nanocomposite structures of graphene nanoribbons (GNRs) encapsulated in a carbon nanotube (CNT) has opened a new avenue for exploring new functionalities for applications in nanotechnology. This new class of carbon nanocomposites is expected to possess electronic properties beyond those offered by the constituent parts of nanotubes and nanoribbons; unveiling such new properties and understanding the underlying physics are among the most pressing issues in the study of these promising materials. Here, we report on first-principles calculations of the electronic properties of armchair GNRs encapsulated in a zigzag double-walled CNT. This unique structural configuration produces an intrinsic charge separation with electrons and holes localized in the outer tube and the ribbon, respectively, while the inner tube remains charge-neutral, forming an n-type/intrinsic/p-type semiconducting heterojunction due to the staggered lineup of the band structures of the constituent parts. The electronic band gap of the nanocomposite can be tuned sensitively by the changing width of encapsulated GNRs. Such intrinsic charge separation and widely tunable electronic properties without doping or an external field make this class of new carbon nanocomposites promising candidates for photovoltaic and electronics applications.

Abstractobjective To evaluate whether the Newhints home visits intervention increased the adoption of skin-to-skin care (SSC), in particular, among low birthweight (LBW) (<2.5 kg) babies. Performance of SSC for more than 2 h was, however, low, at only 7.5%, although more than double compared with control zones (RR: 2.72; 95% CI: 1.80-4.10). LBW babies visited and weighed by a volunteer were more likely to receive SSC (P Any = 0.005; P > 2 h = 0.021), greater for LBW babies, particularly for more than 2 h of SSC (P interaction = 0.050).conclusion Newhints successfully promoted the uptake of SSC in rural Ghana. Although findings are encouraging, promotion in rural community settings in sub-Saharan Africa is challenging. Lessons learned can help shape SSC promotion in efforts to increase adoption and save newborn lives.keywords skin-to-skin care, newborn, low birthweight, Ghana
