Uranium liii-edge k3–weighted exafs spectra (left) and the corresponding fourier transforms (ft) (right) of the uranium complexes formed by i. loihiensis mah1 cells at u concentrations of 10−4 and 2.5 10−4 m in seawater, and reference compound (m-autunite)....2.5 10−4 M in seawater, and reference compound (m-autunite).
Structural models used for the fitting procedure of the exafs spectra obtained from the uranium complexes build by the cells of paenibacillus sp. jg-tb8.The left model created from the crystall structure of meta-autunite was used for the fitting procedure of the sample incubated at pH 6 under oxic conditions....
Raman microscopy of autunite minerals at liquid nitrogen temperature... Uranyl micas also known as the autunite minerals are of general formula M(UO2)2(XO4)2.8-12H2O...
Near-infrared spectroscopy of uranyl arsenates of the autunite and metaautunite group... NIR is an excellent technique for the study of the autunite minerals and may be used to distinguish between different autunite phases such as the partially dehydrated autunites for example zeunerite and metazeunerite
