Why is Diffuse Reflectance Spectroscopy Used? One of the main techniques for evaluating the optical properties of materials is optical absorption spectroscopy, or UV-vis spectroscopy. Most absorption ...

Photothermal AFM-IR combines atomic force microscopy and infrared spectroscopy to reveal chemical heterogeneity and ...

The sample preparation before conducting an infrared spectroscopy (IR) study is as critical as the study itself, and the samples which are difficult to dissolve in any IR-transparent solvent are mixed ...

(a) Global observation (July 14, 2025, radiance (light intensity) at a wavelength of 767 nm), (b) Focus Mode observation over Tokyo (July 17, 2025, radiance at a wavelength of 767 nm), and (c) ...

The Extremely Large Telescope (ELT), currently under construction in northern Chile, will give us a better view of the Milky Way than any ground-based telescope before it. It's difficult to overstate ...

When an ecological disaster releases toxins into the environment, extensive sampling and analysis is vital to ensure the health and safety of the people affected. Surface-enhanced vibrational ...

Near-IR spectroscopy belongs to the group of vibrational spectroscopy techniques, along with mid-infrared spectroscopy (primarily FT-IR) and Raman spectroscopy. The first near-IR spectrometers were ...

Digital imaging that includes spectral estimation can overcome limitations of typical digital photography, such as limited color accuracy and constraints to a predefined viewing condition or a ...
