Towards atomic resolution in sodium titanate nanotubes using near-edge X-ray-absorption fine-structure spectromicroscopy combined with multichannel multiple-scattering calculations

Beilstein Journal of Nanotechnology, 2012
Recent advances in near-edge X-ray-absorption fine-structure spectroscopy coupled with transmission X-ray microscopy (NEXAFS–TXM) allow large-area mapping investigations of individual nano-objects with spectral resolution up to E/ΔE = 104 and spatial ...

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

Combinatorial Nb‐Doped TiO2 Wafers: Phase‐Defect Coengineering for Efficient and Reusable Photocatalysis

Advanced Energy and Sustainability Research, Volume 7, Issue 3, March 2026.
Combinatorial Nb‐doped TiO2 wafers with a lateral dopant gradient enable rapid mapping of how phase composition and defects influence photocatalytic activity. Optimized Nb content generates mixed anatase–rutile phases together with beneficial Ti3+ and oxygen vacancy defects, boosting dye‐degradation efficiency fivefold.

Broadening the Workflow for Synchrotron‐Based X‐Ray Fluorescence and X‐Ray Absorption Spectroscopy Imaging of Low‐Abundance Cellular Metals

Chemistry–Methods, Volume 6, Issue 3, March 2026.
We present an accessible plunge‐freezing and freeze‐drying workflow for preparing adherent mammalian cells for synchrotron‐based nanofocused X‐ray fluorescence (XRF) microscopy and X‐ray absorption spectroscopy (XAS), enabling sub‐micron mapping of metal distribution and chemical speciation.

Electronic structure of single-crystalline Mg$_x$Al$_{1-x}$B$_2$ probed by x-ray diffraction multipole refinements and polarization-dependent x-ray absorption spectroscopy

, 2012
X-ray diffraction multipole refinements of single-crystalline Mg$_x$Al$_{1-x}$B$_2$ and polarization-dependent near-edge x-ray absorption fine structure at the B 1$s$ edge reveal a strongly anisotropic electronic structure.

Suppression of spin-state transition in epitaxially strained LaCoO_{3}

, 2008
Epitaxial thin films of LaCoO_{3} (E-LCO) exhibit ferromagnetic order with a transition temperature T_c = 85 K, while polycrystalline thin LaCoO_{3} films (P-LCO) remain paramagnetic.

Sequential deposition enables suppression of spontaneous donor enrichment of the surface in spin-coated films

JPhys Materials
Sequential deposition (SD) through independent processing of donor and acceptor materials, has emerged as a promising strategy to enable better control over the active layer morphology of organic solar cells.

Core-level spectra and molecular deformation in adsorption: V-shaped pentacene on Al(001)

Beilstein Journal of Nanotechnology, 2015
By first-principle simulations we study the effects of molecular deformation on the electronic and spectroscopic properties as it occurs for pentacene adsorbed on the most stable site of Al(001).
