A structural study of a C3H3 species coadsorbed with CO on Pd(1 1 1) [PDF]

open access: yes, 2008
The combination of chemical-state-specific C 1s scanned-energy mode photoelectron diffraction (PhD) and O K-edge near-edge X-ray absorption fine structure (NEXAFS) has been used to determine the local adsorption geometry of the coadsorbed C3H3 and CO ...

Interface structure and corrosion protection of hybrid particles prepared via surfactant- and silica-assisted wet ball milling

open access: yesResults in Surfaces and Interfaces, 2022
The paper proposes a simple way to simultaneously modify iron particles with both silica and surfactant molecules, which involves wet ball milling of iron with silica glass and surfactants (stearic and n-perfluorononanoic acid).

Carbon storage and DNA absorption in allophanic soils and paleosols [PDF]

open access: yes, 2014
Andisols and andic paleosols dominated by the nanocrystalline mineral allophane sequester large amounts of carbon (C), attributable mainly to its chemical bonding with charged hydroxyl groups on the surface of allophane together with its physical ...

NEXAFS spectra and specific dissociation of oligo-peptide model molecules

open access: yesAIP Advances, 2019
Total-ion-yield near-edge X-ray absorption fine-structure (NEXAFS) spectra of three oligo-peptide model molecules were recorded. The NEXAFS spectra were also calculated with time-dependent density functional theory; the calculated spectra are consistent ...

NEXAFS at nitrogen K-edge and titanium L-edge using a laser-plasma soft x-ray source based on a double-stream gas puff target

open access: yesAPL Photonics, 2019
We present a possibility of reaching higher energy absorption edges of organic materials, beyond the carbon K-edge, in the near edge X-ray absorption fine structure (NEXAFS) spectroscopy technique using a compact laser-produced plasma soft X-ray (SXR ...
