Near-infrared dyes are vital for bioimaging and therapy due to their deep tissue penetration and reduced background interference, with aza-BODIPYs standing out for their stability and tunability. The Vicente group synthesized new aza-BODIPY derivatives with absorption and emission between 678–855 nm, demonstrating how specific para-phenyl substitutions precisely modulate absorption, emission, and fluorescence efficiency.

When X-rays knock out a core electron, they trigger electron motion that unfolds in attoseconds. The Lopata research group used advanced simulations to test whether the shape of the core-hole changes this motion and found it remains nearly the same across inner-shell orbitals, a discovery that expands opportunities for ultrafast X-ray experiments at the attosecond scale.

Coastal wetlands are vital for shoreline protection, carbon storage, and storm resilience; however, studying belowground root biomass and necromass is a challenge using traditional methods. A new paper co-authored by Prof. Les Butler demonstrates how Optical Coherence Tomography and machine learning can deliver fine-scale, non-destructive insights into root morphology and decay.

The Pojman Research Team published a new study on using 1,1,2,2-tetraphenylethanediol (TPED) as a safer, shelf-stable alternative to peroxide initiators in the frontal polymerization of acrylates. TPED produces void-free materials, offering the added benefit of commercial availability and longer shelf life.
