Real time observation of X-ray-induced surface modification using simultaneous XANES and XEOL-XANES. [PDF]

Anal Chem, 2013
In experiments preliminary to the design of an X-ray-excited optical luminescence (XEOL)-based chemical mapping tool we have used X-ray micro (4.5 × 5.2 μm) and macro (1 × 6 mm) beams with similar total fluxes to assess the effects of a high flux density beam of X-rays at energies close to an absorption edge on inorganic surfaces in air.

Toward Noninvasively Imaging pH at the Surface of Implanted Orthopedic Devices in Live Rabbits Using X-ray Excited Luminescence Chemical Imaging. [PDF]

Adv Healthc Mater
Imaging pH in a live rabbit at the surface of a sensor‐coated titanium plate using X‐ray excited luminescent chemical imaging (XELCI). A raster scanning X‐ray beam generates radioluminescence from a spot on the sensor, and the luminescence passes through the tissue and is collected at two wavelengths to determine local pH.

3D and Multimodal X-Ray Microscopy Reveals the Impact of Voids in CIGS Solar Cells. [PDF]

Adv Sci (Weinh)
3D X‐ray microscopy quantifies the distribution of voids in thin‐film solar cells and associated electrical performance deficits. Abstract Small voids in the absorber layer of thin‐film solar cells are generally suspected to impair photovoltaic performance.

ZnGa2O4 : Cr3+@Calcium Phosphate Nanocomposite with Near‐Infrared Persistent Luminescence and High Stability

ChemPhotoChem, Volume 7, Issue 12, December 2023., 2023
Shine bright: Persistent luminescent Cr‐doped ZnGa2O4 (CZGO) is incorporated into an amorphous calcium phosphate (ACP) matrix. Annealing CZGO prior to ACP integration greatly improves its luminescence intensity and duration. Zn2+ redistribution from CZGO to ACP is identified, leading to the formation of Zn3(PO4)2 when immersed in water.

Bandwidth Control and Symmetry Breaking in a Mott‐Hubbard Correlated Metal

Advanced Functional Materials, Volume 33, Issue 41, October 9, 2023., 2023
The strength of the electron correlation is tuned by strain in a model system of SrVO3. Strain is shown to control the hopping between orbitals (bandwidth) and the orbital occupation. Tensile strain is shown to drive this metallic system toward a Mott insulating state.

Interplay between Crystal Structure and Optical Response in Plateau–Rayleigh Zn2GeO4/SnO2 Heterostructures

Advanced Photonics Research, Volume 4, Issue 8, August 2023., 2023
Decorated semiconductor nanowires (NWs) are promising architectures for next‐generation nanoelectronic devices. Zn2GeO4/SnO2 NW architecture, which is produced by the Plateau–Rayleigh instability, is characterized by combining multiple synchrotron nano‐analysis techniques (nano X‐ray fluorescence, nano X‐ray‐excited optical luminescence, nano X‐ray ...

Quantification of very late xerostomia in head and neck cancer patients after irradiation

Laryngoscope Investigative Otolaryngology, Volume 7, Issue 4, Page 1018-1024, August 2022., 2022
We undertook preliminary studies quantifying xerostomia as a very late toxicity of radiation in HNC patients for use in a planned clinical trial. We found salivary quality of life surveys to differ significantly even 5 or more years after radiation, as did certain salivary compositional analyses. In the survivors of HNC who suffer from late toxicities,

A time resolved microfocus XEOL facility at the Diamond Light Source

Journal of Physics: Conference Series, 2013
We have constructed a Time-Resolved X-ray Excited Optical Luminescence (TR-XEOL) detection system at the Microfocus Spectroscopy beamline I18 at the Diamond Light Source. Using the synchrotron in "hybrid bunch mode", the data collection is triggered by the RF clock, and we are able to record XEOL photons with a time resolution of 6.1 ps during the 230 ...

Cooperative Atomic Mechanism of Emergent Tilted Magnetic Anisotropy

Advanced Electronic Materials, Volume 11, Issue 21, December 17, 2025.
This study reveals a novel atomic mechanism behind magnetic anisotropy, where single‐ion anisotropy at dilute atomic sites establishes a long‐range anisotropic magnetic order via exchange interaction. The resulting exchange‐induced anisotropy contributes comparably to the single‐ion anisotropy, offering a promising strategy for engineering magnetic ...
