Deconvolution problems in x-ray absorption fine structure [PDF]

, 2001
A Bayesian method application to the deconvolution of EXAFS spectra is considered. It is shown that for purposes of EXAFS spectroscopy, from the infinitely large number of Bayesian solutions it is possible to determine an optimal range of solutions, any ...

Transmission properties of the X-ray window for the SIXA spectrometer [PDF]

, 1996
The ultrathin X-ray entrance window for the spaceborne spectrometer SIXA was characterised using synchrotron radiation. X-ray absorption fine structure near the absorption edges of the constituting elements (aluminium, carbon, oxygen and nitrogen) was ...

XAFS Analysis of Sulfuric Acid Solution Related to the Effect of Bi in Suppressing the Disproportionation Reaction of Mn3+ in Mn/Ti Redox Flow Cells

Electrochemistry, 2023
In sulfuric acid (H2SO4) aqueous solutions containing manganese (Mn) and titanium (Ti) ions, which are used for the positive electrolyte in redox flow (RF) batteries, the addition of a small quantity of bismuth (Bi) has been found to be very effective in

Spontaneous Chelation-Driven Reduction of the Neptunyl Cation in Aqueous Solution. [PDF]

, 2020
Octadentate hydroxypyridinone (HOPO) and catecholamide (CAM) siderophore analogues are known to be efficacious chelators of the actinide cations, and these ligands are also capable of facilitating both activation and reduction of actinyl species ...

Integration of X-ray absorption fine structure databases for data-driven materials science

Science and Technology of Advanced Materials: Methods, 2023
With the aim of introducing data-driven science and establishing an infrastructure for making X-ray absorption fine structure (XAFS) spectra findable and reusable, we have integrated XAFS databases in Japan. This integrated database (MDR XAFS DB) enables

Preparation, structural characterisation and antibacterial properties of Ga-doped sol-gel phosphate-based glass [PDF]

, 2009
A sol-gel preparation of Ga-doped phosphate-based glass with potential application in antimicrobial devices has been developed. Samples of composition (CaO)(0.30)(Na2O)(0.20-x) (Ga2O3) (x) (P2O5)(0.50) where x = 0 and 0.03 were prepared, and the ...

Three-dimensionally confined diluted magnetic semiconductor clusters. Zn1−xMnxS [PDF]

, 1991
We report the first example of a dilute magnetic semiconductor (DMS) confined in all three dimensions (DMS quantum dot). Zn0.93Mn0.07S clusters of not, vert, similar 25 Å diameter are successfully synthesized inside a glass matrix and fully characterized

Structural and electronic investigation of ZnO nanostructures synthesized under different environments

Heliyon, 2018
An explicit study of comparison on the basis of structure and electronic properties of ZnO nanostructures was discussed. ZnO synthesized by sol-gel and hydrothermal method without using any surfactant leads to the formation of two different morphologies.
