Contrasting mineral dust abundances from X-ray diffraction and reflectance spectroscopy [PDF]

Atmospheric Measurement Techniques, 2022
Mineral dust particles dominate aerosol mass in the atmosphere and directly modify Earth's radiative balance through absorption and scattering. This radiative forcing varies strongly with mineral composition, yet there is still limited knowledge on the ...

In vivo diffuse reflectance spectroscopic analysis of fatty liver with inflammation in mice

Surgery Open Science, 2021
Background: Nonalcoholic steatohepatitis is a progressive liver disease that can lead to cirrhosis, hepatocellular carcinoma, and hepatic failure. Thus, the diagnosis of nonalcoholic steatohepatitis, especially discrimination from nonalcoholic fatty ...
