Near Infra-red Spectroscopy of V838 Monocerotis
Near IR, multi epoch, spectroscopic and photometric observations of the enigmatic, eruptive variable V838 Mon in the JHK bands are reported. One of unusual features of the spectra is the detection of several strong neutral TiI lines in emission in the K band. From the strength of these lines, the mass of the ejected envelope is estimated to be in the range 10−7 to 10−5 M . The spectra also show...
متن کاملSpectral relationships for atmospheric correction. I. Validation of red and near infra-red marine reflectance relationships.
The present study provides an extensive overview of red and near infra-red (NIR) spectral relationships found in the literature and used to constrain red or NIR-modeling schemes in current atmospheric correction (AC) algorithms with the aim to improve water-leaving reflectance retrievals, ρw(λ), in turbid waters. However, most of these spectral relationships have been developed with restricted ...
متن کاملInfra-red photoresponse of mesoscopic NiO-based solar cells sensitized with PbS quantum dot
Sensitized NiO based photocathode is a new field of investigation with increasing scientific interest in relation with the development of tandem dye-sensitized solar cells (photovoltaic) and dye-sensitized photoelectrosynthetic cells (solar fuel). We demonstrate herein that PbS quantum dots (QDs) represent promising inorganic sensitizers for NiO-based quantum dot-sensitized solar cells (QDSSCs)...
متن کاملNear infra-red interactance for nutritional assessment of dialysis patients.
BACKGROUND Malnutrition is a common problem in dialysis patients and may affect up to one-third of patients. Near-infrared interactance (NIR) is a novel approach to estimate body composition and per cent total body fat. METHODS We used near-infrared interactance (Futrex 5000) to estimate the body composition including body fat percentage, as well as subjective global assessment (SGA), anthrop...
متن کاملRapid Analysis of Cane Juice by near Infra-red
An investigation was carried out to test the suitability of near infra-red reflectance (NIR) for rapidly estimating cane quality components. A large number of mixed cane juice samples of known pol, brix, sucrose, fructose, and glucose content were used to calibrate a Technicon Model 450 InfraAlyzer. Regression analyses indicated that brix, pol, and sucrose values obtained were closely correlate...
