Tautomerization Kinetics of Thiouracils at Low Temperatures Driven Solely by Quantum‐Mechanical Tunnelling: Predictions of Suitable Candidates for Future Experiments

International Journal of Chemical Kinetics, Volume 58, Issue 6, Page 269-277, June 2026.
ABSTRACT In the past two decades numerous experiments have been conducted on the kinetics of reactions occurring at low temperatures on inert matrices. In particular, unimolecular proton‐transfer photo‐reactions of compounds containing a carbon–sulfur double bond, or thione group C═S, can lead to the formation of higher energy isomers or tautomers with

Light‐Activated Protein‐Imprinted Hydrogels Capable of Translating Protein Surface Accessibility Into Missing‐Peptide Footprints

Small Structures, Volume 7, Issue 6, June 2026.
Light‐activated protein‐imprinted PFPA‐functionalized hydrogels crosslink captured proteins and report protein surface accessibility as missing‐peptide patterns readable by standard LC‐MS/MS. Mass spectrometry (MS)‐based structural proteomics can reveal higher‐order structural features in complex biological samples, but many covalent footprinting and ...

Advancing Heliophysics and Space Weather Modeling Through Open Science

Space Weather, Volume 24, Issue 6, June 2026.
Abstract We present a community‐wide effort to develop a strategy and action plan to advance heliophysics and space weather modeling through open science. While open science has the potential to enhance the quality and pace of scientific discovery, its application to scientific modeling requires more careful consideration regarding open data and open ...

How to Imagine Educational AI: The Filling of a Pail or the Lighting of a Fire?

Educational Theory, Volume 76, Issue 3, Page 316-338, June 2026.
Abstract Recent advances in artificial intelligence (e.g., machine learning, generative AI) have led to increased interest in its application in educational settings. AI companies hope to revolutionize teaching and learning by tailoring material to the individual needs of students, automating parts of teachers' jobs, or analyzing educational data to ...

Combustion and Pyrolysis EA‐IRMS Techniques to Determine the δ2H of Diamonds

Rapid Communications in Mass Spectrometry, Volume 40, Issue 10, 30 May 2026.
ABSTRACT Rationale Diamonds are generally considered to be metasomatic minerals originating from the Earth's mantle. They formed through the interaction of carbon‐bearing fluids or melts with the surrounding deep lithology. Most knowledge about the formation of diamonds comes from studying their mineral inclusions or stable isotopes.
