Advanced Science, EarlyView.A femtosecond UV pump–probe microscope resolves binding‐induced changes in protein excited‐state dynamics and converts these intrinsic contrasts into an equilibrium affinity readout. By probing tryptophan responses directly in solution, the approach enables quantitative determination of dissociation constants without labeling or immobilization ...

Perfluoro effect in the photoelectron spectra of quinoline and isoquinoline [PDF]
, 1972 The high-resolution He 584Aophotoelectron spectra of heptafluoroquinoline and heptafluoroisoquinoline are compared with those of the parent compounds. Shifts in π ionisation potentials, due to the fluorine substitution, can be described with an inductive

Angewandte Chemie, Volume 138, Issue 5, 28 January 2026.An iron‐catalyzed protocol for the cascade cyclization of N‐aryl and N‐benzoyl acrylamides promoted by methane and other gaseous alkanes is reported. The current protocol provides an efficient platform for the conversion of feedstock gaseous alkanes into complex and medicinally relevant N‐heterocycles.
