Quick AS NEXAFS Tool(QANT): a program for NEXAFS loading and analysis developed at the Australian Synchrotron

Journal of Synchrotron Radiation, 2016
An analysis program for near-edge X-ray absorption fine-structure (NEXAFS) spectra has been developed and implemented at the soft X-ray beamline of the Australian Synchrotron. The program allows for instant viewing of corrected data channels including normalizations to a standard, double normalizations when the standard itself has an undesired spectral

NEXAFS Spectroscopy of Condensed N-alkanes [PDF]

, 2020
The carbon 1s Near-Edge X-ray Absorption Fine Structure (NEXAFS) spectra of alkanes vary with chain length, substitution, and phase change. For short gaseous alkanes, the carbon 1s NEXAFS spectra of alkanes are dominated by Rydberg transitions with ...

Ultra‐Thin and Highly Insulating Aromatic Monolayers by N‐Heterocyclic Carbenes

Angewandte Chemie, EarlyView.
By using N‐heterocyclic carbenes extremally insulating and at the same time as thin as 0.3 nm molecular films are formed. The charge transport calculations indicate absence of destructive quantum interference effect which was so far the only way to suppress conductivity in aromatic molecules.

VerSoX B07-B: a high-throughput XPS and ambient pressure NEXAFS beamline at Diamond Light Source

Journal of Synchrotron Radiation
The beamline optics and endstations at branch B of the Versatile Soft X-ray (VerSoX) beamline B07 at Diamond Light Source are described. B07-B provides medium-flux X-rays in the range 45–2200 eV from a bending magnet source, giving access to local ...

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

Results 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).

NEXAFS spectra and specific dissociation of oligo-peptide model molecules

AIP 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

APL 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 ...

Controlled Triazine-Based Covalent Functionalization of Black Phosphorus for Degradable Hybrid Materials. [PDF]

Small
A scalable triazine‐based covalent functionalization strategy of black phosphorus nanosheets provides controlled P‐N surface chemistry with enhanced grafting density in the presence of a phase‐transfer catalyst. As a representative example, BP‐sulfated polymer conjugates exhibit strong in vitro antiviral activity against enveloped viruses and ...
