This study employs a spectral fitting technique to retrieve optical parameters of coastal seawaters from hyperspectral reflectance spectra. The model used includes both the atmospheric effects and the ...

All light is made up of waves of electromagnetic radiation. A spectroscope spreads each different wavelength to a different position within a spectrum of light. Music is digitally recorded as circular ...

We analyze all-optical switching in chlorophyll-A (Chl-A) molecules for different combinations of pump-probe wavelengths, based on nonlinear intensity-induced excited-state absorption. It is shown ...

Due to the L-theanine levels in matcha, it’s generally considered better for gut health than coffee. Coffee is more acidic ...

Commercialization of photoelectrochemical (PEC) water-splitting technology is hindered by the slower kinetics of oxygen evolution in the currently available photoanodes. Light absorption, ...

Photosynthesis, the way plants and some tiny organisms turn sunlight into energy, works incredibly well even though ...

Nonphotochemical quenching mechanisms regulate light harvesting in oxygenic photosynthesis. Measurement techniques for nonphotochemical quenching have typically focused on downstream effects of ...

There are, however, intrinsic absorption features in the spectra of all actual diamonds. As discussed in our 2013 article, most diamonds also contain lattice defects which, in sufficient ...
