Effect of crystallinity and thickness on thermal transport in layered PtSe2

npj 2D Materials and Applications, 2022
We present a comparative investigation of the influence of crystallinity and film thickness on the acoustic and thermal properties of layered PtSe2 films of varying thickness (1–40 layers) using frequency-domain thermo-reflectance, low-frequency Raman ...

Two Methods of Near Infrared Reflectance Spectroscopy for Determining the Digestibility and Energy Value of Feeds [PDF]

, 1997
Two groups of rations with known in vivo digestibility and energy values were used in this study. These rations were composed of Italian ryegrass only (lRO. n = 45), and combination of Italian ryegrass and concentrates (lRC, n = 58).

Effects of Atmospheric, Topographic, and BRDF Correction on Imaging Spectroscopy-Derived Data Products

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Surface reflectance is an important data product in imaging spectroscopy for obtaining surface information. The complex retrieval of surface reflectance, however, critically relies on accurate knowledge of atmospheric absorption and scattering, and the ...
