Here is a photo that was taken using the starter astrophotography kit listed above under the dark skies of the Black Forest Star Party in 2019. The camera used was a Canon EOS 60Da (more sensitive to the h-alpha wavelength) and an Optolong UV/IR cut filter to prevent star bloat. Modify...
Functional multiwall carbon nanotubes (f-MWCNTs) are of significant interest due to their dispersion ability in the aqueous phase and potential application in environmental, nanotechnology, and biological fields. Herein, we functionalized MWCNTs by a simple acid treatment under ultra-sonification, which ...
Figure 1. Molecular transmittance in the MVIRI/VIS band spectral range for the following gases: water vapor (blue), ozone (magenta) and oxygen (orange). The green line shows the pre-launch SRF of MVIRI/VIS band on board Meteosat-7. Wavelength is expressed in μμm. The routine vicario...
There is also some contribution to the IR emission from the accretion disk, and this contribution increases with decreasing wavelength. The variability in J and K is not entirely simultaneous, which may be due to the differing contributions of the radiation from the accretio...
Mouse striatum-derived neurospheres have been used to study myelination after transplantation into shiverer mice for the study of glial-axonal interactions that culminate in myelin formation in the CNS [17–19]. Previously, we used advanced imaging techniques together with a range of green ...
Aging is associated with an increase in spectral optical density and a concomitant decrease in transmittance of the human crystalline lens, especially in the short wavelength blue visible region of the light spectrum1,2,3. This age-related change in the crystalline lens, affects various visual4,5...
Glyoxalase pathway, comprising glyoxalase I (GLY I) and glyoxalase II (GLY II) enzymes, is the major pathway for detoxification of methylglyoxal (MG) into D-lactate involving reduced glutathione (GSH). However, in bacteria, glyoxalase III (GLY III) with
After combing through my parts bin, I found another IR LED and measured it: 815nm. Still not right. I was fortunately able to juuust barely be able to measure the wavelength, though. Looks like a very broad band 815nm, if the peak stretches all the way to 750nm. ...
Thus, the melt pool geometry was determined independently of the emissivity. The transmission spectra of the glass ceramic and the ZnS glass were evaluated to enable the calibration of the transmission coefficient. With a spectral range of 3 to 5 µm (range of the lens setup used), the ...
Carrier transport in these materials can be understood easily if we treat them as metals having plasma frequency in the IR range and transparent in the visible range. In 1924, H. Mott-Smith derived the accurate formula for the characteristic plasma frequency [40,41,42] 𝜔𝑝=4𝜋𝑛...
