Thermodynamic Properties and Anharmonic Effects in XAFS Based on Anharmonic Correlated Debye Model Debye–Waller Factors

open access: yesAdvances in Materials Science and Engineering, 2018
Thermodynamic properties and anharmonic effects in X-ray absorption fine structure (XAFS) have been studied based on the anharmonic correlated Debye model Debye–Waller factors presented in terms of cumulant expansion.

Studies on Surface and Interface with X-ray Absorption Fine Structure (XAFS). XAFS Study of Self-Assembled Monolayers.

open access: yesHyomen Kagaku, 2002
The molecular orientation and the molecule-substrate interface structure of self-assembled monolayers of alkanethiol and its related molecules have been investigated by use of X-ray absorption fine structure (XAFS). The molecular orientation is mainly dependent on the molecular density, while for the ordering of molecular arrangement, which is ...

Chemical State Analysis of the Periostracum in the Corbicula Clam Hatched in Lake Biwa

open access: yesJournal of Water and Environment Technology, 2020
The periostracum of corbicula clams is a unique outermost organic layer secreted from the inner surface of the outer mantle. It records the environmental history of corbicula clams which inhabited Lake Biwa. Two types of corbicula clams,

Solving self-absorption in fluorescence

open access: yesIUCrJ, 2019
One of the most common types of experiment in X-ray absorption spectroscopy (XAS) measures the secondary inelastically scattered fluorescence photon. This widespread approach has a dominant systematic of self-absorption of the fluorescence photon.
