Martian meteorite Northwest Africa (NWA) 8114 – a paired stone to NWA 7034 – provides an opportunity to examine the thermal history of a martian regolith and study near-surface processes and ancient environmental conditions near an impact crater

The magnetic flux exclusion known as Meissner effect resulting from a perfectly diamagnetic susceptibility χ=−1 is one of the defining features of type-I superconductivity. More recently some materials have been reported to undergo a transition to

Publikováno v: Journal of Electroanalytical Chemistry. 610:46-56

The structural origins of ion recognition by electrochemically addressable poly[Ni( salen )] thin films are explored using in situ X-ray spectroscopy. XANES and EXAFS provided the local environment (nearest and next-nearest neighbours) around the Ni

Structure of amorphous GexSe1−x and GexSeyZnz thin films: an EXAFS study

Autor: E.A. Davis, J. Choi, S J Gurman

Publikováno v: Journal of Non-Crystalline Solids. 297:156-172

Extended X-ray absorption fine structure (EXAFS) measurements have been made on thin films of a-Ge x Se 1− x with 0.2 x x x Se y Zn z films show that the lengths of Ge–Zn and Se–Zn bonds are 2.57±0.05 and 2.44±0.03 A, independent of the compo

Multiple-electron excitation in X-ray absorption: a simple generic model

Autor: Mervyn Roy, J. D. Lindsay, S. Louch, S J Gurman

Publikováno v: Journal of Synchrotron Radiation. 8:1103-1108

The probability of multiple-electron excitation in X-ray absorption is calculated using a simple generic model. The model permits calculations to be made for all atoms with little input data or computing effort. The high-energy limit of this probabil
