Frustrated Radical Pairs: From Fleeting Intermediates to Isolable Species

open access: yesChemistry – A European Journal, Volume 31, Issue 9, February 12, 2025.
Herein we report the design of stable para‐substituted triarylamine−DDQ radical ion pairs (RIPs). We investigated several combinations using a wide variety of spectroscopic methods such as IR, EPR and NMR, both in solution and in the solid state. We quantified the degree of single‐electron transfer (SET) and found that both the substituents (MeO > tBu >

Antarctic Geothermal Soils Exhibit an Absence of Regional Habitat Generalist Microorganisms

open access: yesEnvironmental Microbiology, Volume 27, Issue 1, January 2025.
Antarctic geothermal sites are highly isolated islands of warmth and moisture. We studied the community structure, predicted functions and ecology of the microorganisms inhabiting these sites, with the finding that high dispersal rates have resulted in an absence of regional habitat generalists between these sites.

Enhanced Electrical Characterization of Dusty Solar Modules: Integrating Outdoor Experiments With Single‐ and Double‐Diode Models

open access: yesInternational Journal of Energy Research, Volume 2025, Issue 1, 2025.
This study addresses a research gap regarding the impact of dust accumulation on photovoltaic (PV) modules, with a specific focus on parameter extraction using single‐ and double‐diode models (SDMs and DDMs) under dusty conditions. While dust effects on PV performance are well‐studied, few have explored how existing models can accurately represent ...
