A new study establishes an experimentally validated basis for predicting excitonic properties via dielectric screening.

Once it was clear that the finding was most likely real, the team took a closer look at the chemistry of the material nearest ...

Birgitta Schultze-Bernhardt and her team at the Institute of Experimental Physics at Graz University of Technology (TU Graz) have developed a new type of UV dual-comb spectrometer that detects gaseous ...

A new AI-powered chip from UC Davis can analyze light and chemicals using a device tiny enough to fit almost anywhere. By combining smart silicon sensors with machine learning, it achieves lab-style ...

I tested the TLM-2 micro-spectrometer with sunlight, a deuterium lamp, and a mercury arc lamp to analyze its spectral performance across different light sources. #MicroSpectrometer #SpectralAnalysis ...

Raman, NIR, and UV-VIS spectroscopy are the three main methods used in this field. All three fall within the broader categories of vibrational and electronic spectroscopy, but they differ ...

Across the U.S., hundreds of sites on land or in lakes and rivers are heavily contaminated with hazardous waste produced by human activity. Many of these places, designated as Superfund sites by the ...

Lithuanian researchers at the Center for Physical Sciences and Technology (FTMC), Habil. Dr. Gediminas Niaura and Dr. Martynas Talaikis, together with international colleagues, have for the first time ...

Researchers show copper nanoparticles power UV SERS to detect key biochemical markers, a discovery that could pave the way to fast and reliable skin cancer diagnostics. (Nanowerk News) Lithuanian ...
