A feather hydrogen (delta2H) isoscape for Brazil.
Alquezar RD, Costa FJV, Sena-Souza JP, Nardoto GB, Hobson KA. Alquezar RD, et al. PLoS One. 2022 Aug 3;17(8):e0271573. doi: 10.1371/journal.pone.0271573. eCollection 2022. PLoS One. 2022. PMID: 35921277 Free PMC article.
Spatial patterns of stable isotopes in animal tissues or "isoscapes" can be used to investigate animal origins in a range of ecological and forensic investigations. Here, we developed a feather hydrogen isotope (delta2Hf) isoscape for Brazil based on 192 samp …

Efficient Aliphatic Hydrogen-Isotope Exchange with Tritium Gas through the Merger of Photoredox and Hydrogenation Catalysts.
Yang H, Huang Z, Lehnherr D, Lam YH, Ren S, Strotman NA. Yang H, et al. J Am Chem Soc. 2022 Mar 23;144(11):5010-5022. doi: 10.1021/jacs.1c13265. Epub 2022 Mar 9. J Am Chem Soc. 2022. PMID: 35263094
Wilkinson's catalyst, commonly used for catalytic hydrogenations, was exploited as a precatalyst for activation of D(2) or T(2) and hydrogen atom transfer. In this combined methodology and mechanistic study, we demonstrate that by coupling photocatalysis with Rh cat …
