Direct observation of changing NO (x) lifetime in North American cities.
Laughner JL, Cohen RC. Laughner JL, et al. Science. 2019 Nov 8;366(6466):723-727. doi: 10.1126/science.aax6832. Science. 2019. PMID: 31699933 Free PMC article.
NO (x) lifetime relates nonlinearly to its own concentration; therefore, by observing how NO (x) lifetime changes with changes in its concentration, inferences can be made about the dominant chemistry occurring in an urban plume. We used satellite obse …

X-ray dose-dependent structural changes of the [2Fe-2S] ferredoxin from Chlamydomonas reinhardtii.
Ohnishi Y, Muraki N, Kiyota D, Okumura H, Baba S, Kawano Y, Kumasaka T, Tanaka H, Kurisu G. Ohnishi Y, et al. J Biochem. 2020 Jun 1;167(6):549-555. doi: 10.1093/jb/mvaa045. J Biochem. 2020. PMID: 32282907
Among many X-ray structures of oxidized Fd have been reported so far, very likely a given number of them was partially reduced by strong X-ray. To understand the precise structural change between reduced and oxidized Fd, it is important to know whether the cr …
