An EXAFS spectroscopic study of Europium (III) complexation with dafone
Materials Research Express, 2020 An extended x-ray absorption fine structure (EXAFS) for L _III Eu crystal edge at 6977 eV energy was studied on an original complex based on europium. The ligand was coordinated entirely with respect to europium atom for [Eu(dafone) _2 Cl _2 .(H _2 O) _2

Polydispersity and EXAFS simulations
, 2009 EXAFS is an important experimental technique for determining the local atomic structure of nanoclusters embedded in a bulk material. In practical cases, nanocluster samples do not contain homogeneous clusters of just one size, and the average cluster ...

EXAFS Structural Determination of the Pt2(P2O5H2)44– Anion in Solution
CHIMIA, 2008 We present the first structural determination of the Pt2(P2O5H2)44– anion in solution by analyzing the extended X-ray absorption fine structure (EXAFS) spectrum of the Pt LIII edge. The data could be fit with a simple model involving single and

Biogenic non-crystalline U(IV) revealed as major component in uranium ore deposits
Nature Communications, 2017 Crystalline uraninite is believed to be the dominant form in uranium deposits. Here, the authors find that non-crystalline U(IV) generated through biologically mediated U(VI) reduction is the predominant U(IV)species in ore deposits, implying that ...

Transformative Surface Chemistry for Long‐Life Nickel‐Rich Layered Cathodes
Small StructuresNi‐rich layered oxides (LiNixMnyCozO2, x + y + z = 1) remain leading cathode candidates for transportation electrification, yet their practical deployment is constrained by lattice‐oxygen release, transition‐metal (TM) dissolution, and the emergence of ...
