Broadband transient full-Stokes luminescence spectroscopy - Nature A high-sensitivity, broadband, transient, full-Stokes spectroscopy setup is demonstrated, which can detect quickly varying small signals from chiral emitters.

Excited to share in @nature.com today: Broadband transient full-Stokes luminescence spectroscopy - detecting the most subtle changes in light polarization over time with unprecedented sensitivity. Grateful for the team that made this possible!😊 www.nature.com/articles/s41... #chirality #light

Most energetic molecule ever made is stable – in liquid nitrogen Nitrogen allotrope releases double the energy of the most powerful chemical explosives

The most energetic molecule ever, and only the second ever neutral nitrogen molecule, hexanitrogen, has been isolated and characterised by researchers in Germany. #ChemSky

🚨 New paper out in Chem Commun!

We report a light-responsive Eu(III) complex with red luminescence switched ON/OFF via a single UV source, no need for dual-wavelength control. Fast, reversible, and efficient!

Thanks to everyone involved in this work 🙌

A huge thank you to the organizers and fellow participants for making this event so enriching. 💡

I am beyond excited to have participated to the PERMolMat Japan-France workshop at ENS Paris-Saclay and presented my work with a poster and a flash presentation!
This journey has been an incredible opportunity to see the latest work of wonderful researchers and connect with them! 🤝

The company said it expects further growth in 2025, with revenue of €1.89bn to €1.94bn and an adjusted operating profit margin at least at the level it reached in 2024, which was 28 per cent. Its results come as the academic sector in many parts of the world is struggling financially and expressing concern about the growing costs of scholarly publishing.

At least Springer Nature is doing well while higher education is collapsing all over the place.

After more than fifty movies watched in the theaters this year and many more to catch up on (Emilia Perez, Anora, The Seed of the Sacred Fig, The Apprentice...), here is my top 10 of my favourite movies of 2024 😁
Can't wait to see what 2025 will hold for us 🎬

Last #FluorescenceFriday of the year today with special Christmas luminophore 🎁 🎄❄️
Nice gift to finish this wonderful year in the lab 🤩

Stenhouse Salts: Visible Light Photoswitches for Protic Environments Designing photoswitches that have large structural changes, are visible-light responsive, and are compatible with water is a major challenge for moving toward applications in biological systems. Despite the potential for Stenhouse salts to be a water-compatible counterpart to the popular DASA photoswitches, there has not yet been any major investigation into their properties as a photoswitch. Here, we report a series of aniline-based Stenhouse salt (AnSten) photoswitches with electron donating and withdrawing groups. AnSten photoswitches reversibly switch from a visible light absorbing isomer to a visible light transparent isomer upon irradiation with green light. The dark equilibrium and switching kinetics are dependent on the electronics of the aniline. These molecules switch reversibly in common protic solvents including water and hydrogels. Stenhouse salts show significant potential as a visible light active, water compatible, negative photochromic, T-type photoswitch with a large structural change.

Great paper from the Peterson lab--developing new photoswitches for protic solvents.

Estimating global article processing charges paid to six publishers for open access between 2019 and 2023 This study presents estimates of the global expenditure on article processing charges (APCs) paid to six publishers for open access between 2019 and 2023. APCs are fees charged for publishing in some ...

🚨 Preprint! We combine our recent open dataset of #APC prices with the article counts per journal-year from #OpenAlex to estimate how much the academic community has paid in APCs over the last 5 years.
