Spectroscopy of a mesospheric ghost reveals iron emissions
Nature Communications, 2023 AbstractMesospheric Green emissions from excited Oxygen in Sprite Tops (ghosts) are infrequent and faint greenish transient luminous events that remain for hundreds of milliseconds on top of certain energetic sprites. The main hypothesis to explain this glow persistence is the long lifetime of excited atomic oxygen at 557.73 nm, a well-known emission ...

Pressure-induced robust emission in a zero-dimensional hybrid metal halide (C9NH20)6Pb3Br12
Matter and Radiation at Extremes, 2021 Zero-dimensional (0D) hybrid metal halides are under intensive investigation owing to their unique physical properties, such as the broadband emission from highly localized excitons that is promising for white-emitting lighting.

Transcriptomics in cancer revealed by Positron Emission Tomography radiomics [PDF]
Scientific Reports, 2020 AbstractMetabolic images from Positron Emission Tomography (PET) are used routinely for diagnosis, follow-up or treatment planning purposes of cancer patients. In this study we aimed at determining if radiomic features extracted from18F-Fluoro Deoxy Glucose (FDG) PET images could mirror tumor transcriptomics.

Atmospheric isoprene measurements reveal larger-than-expected Southern Ocean emissions
Nature Communications, 2023 Abstract Isoprene is a key trace component of the atmosphere emitted by vegetation and other organisms. It is highly reactive and can impact atmospheric composition and climate by affecting the greenhouse gases ozone and methane and secondary organic aerosol formation.
