Zwitterionic Mn(III)‐Tetraphenyl Porphyrins: Water‐Soluble MRI Contrast Agents with High Relaxivity

ChemMedChem, Volume 21, Issue 8, 28 April 2026.
Mn(III)‐based contrast agents (MBCAs) are promising and potentially safer alternatives to the Gd(III)‐based contrast agents (GBCAs) currently used in MRI. This study reports the synthesis, physicochemical characterization and first in vivo application of novel Mn(III)‐tetraphenylporphyrin chelates, bearing zwitterionic sulfobetaine or N‐oxide groups ...

Prospective Environmental Impact Assessment of Scaling Up Perovskite/Silicon Tandem Solar Cells to Industrial Applications

ChemSusChem, Volume 19, Issue 8, 28 April 2026.
This prospective life cycle analysis evaluates perovskite–silicon (PSC–Si) tandem solar cells (TSCs), assessing environmental impacts from their material extraction to end‐of‐life. We compare the environmental impact of four TSC designs with that of silicon PV, highlighting hotspots in tandem architecture, and explore strategies to reduce environmental

Observed and Modeled Changes in Boundary‐Layer and Surface‐Level Actinic Flux Due To Wildfire Smoke Plumes in the California Central Valley in Summer 2018

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 8, 28 April 2026.
Abstract Wildfire smoke is increasingly degrading U.S. air quality via the emission and transport of pollutants. Smoke's direct role as a pollutant is well‐documented; however, smoke also affects pollutant concentration indirectly by changing the shortwave actinic flux necessary for photochemical reactions.
