Iron isotopes in the early marine diagenetic iron cycle
Geology, 2006 Measurements of Fe oxyhydroxides [reactive Fe(III)] in two shallow sediment profiles from reducing and oxic environments on the Arabian Sea margin demonstrate Fe isotope fractionation during early marine diagenesis. Reactive Fe(III) has δ 56 Fe values between −0.77‰ and −0.19‰. Values are lowest at the top of the sediment profile and considerably lower

Isotopic Data on Diet and Mobility from Pictish and Viking Age Orkney
Journal of Open Archaeology DataChanges in diet and mobility isotopes from the Late Iron Age or Pre-Viking phase (PVP, AD 550–790) through the Viking Age (VA, AD 790–1050) and Late Norse phase (LNP, AD 1050–1300) can be used to suggest nuanced socioeconomic and political change ...

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

Angewandte Chemie International Edition, EarlyView.The bimetallic M14 cluster [Co3Ga2]H(μ2‐GaTMP)9 was achieved by a co‐reductive approach utilizing Mg and H2 to selectively deprotect and capture the Ga‐TMP metallo‐ligands, forming a Co/Ga alloyed cluster kernel, making it a structural representative of a related solid‐state counterpart.

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.
