Determination of the Electron Escape Depth for NEXAFS Spectroscopy

, 2016
A novel method was developed to determine carbon atom density as a function of depth by analyzing the postedge signal in near-edge X-ray absorption fine structure (NEXAFS) spectra.

Strain-induced alignment of carbon nanotubes in stretchable polymer sensors revealed by angle-dependent NEXAFS [PDF]

RSC Applied Interfaces
Polymer/carbon nanotube (CNT) composites are widely investigated as stretchable sensors; however, the microscopic mechanisms governing their piezoresistive response under mechanical deformation are often inferred rather than directly demonstrated.

Self-Association of Organic Solutes in Solution: A NEXAFS Study of Aqueous Imidazole [PDF]

, 2015
N K-edge near-edge X-ray absorption fine-structure (NEXAFS) spectra of imidazole in concentrated aqueous solutions have been acquired. The NEXAFS spectra of the solution species differ significantly from those of imidazole monomers in the gas phase and ...

Tuning Amorphous‐Crystalline Catalytic Interfaces by Mechanochemistry: Cu‐Based Metallic Glasses Coupled with Ceria for CO Oxidation

Advanced Materials, Volume 38, Issue 51, 11 September 2026.
Ball‐milling Cu‐based metallic glasses with ceria creates a unique nanostructure where metallic glass particles are wrapped by CeO2 nanoparticles. The intimate integration triggers copper state reorganization during reaction and aging, boosting CO oxidation and COPrOx activity.
