Controlled Delivery and Light‐Induced Release of Magic Spot Nucleotides in Escherichia coli

Angewandte Chemie International Edition, EarlyView.
We synthesized photocaged, clickable and isotope‐labeled “magic spot” Nucleotides and delivered them into Escherichia coli comparing different approaches. Light‐controlled release inside living cells enabled tracking of their conversion from pppGpp to ppGpp by capillary electrophoresis mass spectrometry and revealed their impact on the growth rate of a

Hydrogen Activation via Dihydride Formation on a Rh1/Fe3O4(001) Single‐Atom Catalyst

Angewandte Chemie International Edition, EarlyView.
Deuterium (hydrogen) adsorption on single‐atom Rh1/Fe3O4(001) catalyst does not induce D (H) spillover onto the reducible Fe3O4 support. Instead, a Rh1‐dihydride (Rh−2D or Rh−2H) species forms and D2 or H2desorbs during annealing. ABSTRACT Hydrogen activation is a key elementary step in catalytic hydrogenation.
