Event Overview:
This webinar aims to comprehensively explore transmittance and reflectance measurements for both transparent and non-transparent crystal and thin film materials. Through detailed studies, it will be demonstrated how to accurately estimate the effects of various physical processes, including thermal treatments, ionizing radiation exposure, optical exposure, and mechanical treatments, on both crystals and thin films. Additionally, this webinar will provide in-depth guidance on estimating the optical band gap of thin films using the Tauc and Kubelka-Munk methods.

Microplastics Widespread on Catalan Beaches, Study Finds
March 28th 2025In a recent study published in Marine Pollution Bulletin, a team of researchers from several Spain and Portugal universities and institutions (Rovira i Virgili University, Universitat de Barcelona, University of Porto, and Institut d'Investigació Sanitaria Pere Virgili (IISPV) assessed microplastic (MP) contamination along the Mediterranean coastline.
Using Spectroscopy to Reveal the Secrets of Space
March 25th 2025Scientists are using advanced spectroscopic techniques to probe the universe, uncovering vital insights about celestial objects. A new study by Diriba Gonfa Tolasa of Assosa University, Ethiopia, highlights how atomic and molecular physics contribute to astrophysical discoveries, shaping our understanding of stars, galaxies, and even the possibility of extraterrestrial life.
New Telescope Technique Expands Exoplanet Atmosphere Spectroscopic Studies
March 24th 2025Astronomers have made a significant leap in the study of exoplanet atmospheres with a new ground-based spectroscopic technique that rivals space-based observations in precision. Using the Exoplanet Transmission Spectroscopy Imager (ETSI) at McDonald Observatory in Texas, researchers have analyzed 21 exoplanet atmospheres, demonstrating that ground-based telescopes can now provide cost-effective reconnaissance for future high-precision studies with facilities like the James Webb Space Telescope (JWST) (1-3).
