Beagle: a near-edge X-ray absorption fine-structure spectroscopy data processing solution for beamline experiments at Pohang Accelerator Laboratory

open access: yesJournal of Synchrotron Radiation
Near-edge X-ray absorption fine-structure (NEXAFS) spectroscopy is a powerful tool for identifying chemical bonding states at synchrotron radiation facilities. Advances in new materials require researchers in both academia and industry to measure tens to

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

open access: yesBeilstein 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).

Photochemistry of Aromatic N‐Oxides in Water Probed by Time‐Resolved X‐ray Absorption Spectroscopy

open access: yesChemistry – A European Journal, Volume 32, Issue 29, 7 August 2026.
Time‐resolved XAS at the nitrogen and oxygen K‐edges is applied to the photorearrangement of two N‐oxides in water. Pyridine N‐oxide rapidly forms the oxaziridine isomer. Pyridazine N‐oxide undergoes ring opening to the diazo compound, without any evidence of intermediates.

Spherulite in the modern aragonitic travertine stromatolite has a calcite core with exopolymers

open access: yesSedimentology, Volume 73, Issue 5, Page 1421-1434, August 2026.
ABSTRACT Spherulites are spherical to ellipsoidal particles formed by various crystalline substances and can be abiotically synthesised in the laboratory. Among various spherulite types, spherulites composed of calcium carbonate are also found in various natural environments, but their abiotic or biotic origins are still controversial.

Effect of the fluorination technique on the surface-fluorination patterning of double-walled carbon nanotubes

open access: yesBeilstein Journal of Nanotechnology, 2017
Double-walled carbon nanotubes (DWCNTs) are fluorinated using (1) fluorine F2 at 200 °C, (2) gaseous BrF3 at room temperature, and (3) CF4 radio-frequency plasma functionalization.

Effect of co-adsorption dye on the electrode interface (Ru complex/TiO2) of dye-sensitized solar cells

open access: yesAIP Advances, 2013
The co-adsorption interface structure of isothiocyanate (R-N=C=S) in N719 dye was investigated using a system of N719 alone and an N719 + D131 co-adsorption system.

Probing molecular orientation of donors and acceptors in all-polymer blend films by near-edge x-ray absorption fine structure spectroscopy

open access: yesJPhys Materials
The molecular orientation is crucial for the efficiency of organic solar cells. A face-on orientation, in which the $\pi - \pi $ stacking direction is oriented perpendicular to the substrate, is typically preferred because it enhances vertical charge ...

Influence of bond defects on coiling of graphite

open access: yesScience and Technology of Advanced Materials, 2006
The effect of annealing at 1400 °C in argon on the bond structure of graphite ball milled for 100 h at 400 rpm in polar (water) and in non-polar (n-dodecane) liquids was investigated primarily by near-edge X-ray absorption fine structure spectroscopy ...
