X-Ray Absorption Spectromicroscopy of Aqueous Samples
X-ray PhotoElectron Emission Microscopy (X-PEEM) has found numerous applications in the surface microchemical analysis of materials science and biological specimens. We have reconfigured the MEPHISTO X-PEEM instrument, installed at the UW-Synchrotron Radiation Center, to measure true x-ray transmission spectra by converting transmitted photons to photoelectrons via a thin photocathode layer of ...
متن کاملCharacterization of Biomaterials by Soft X-Ray Spectromicroscopy
Synchrotron-based soft X-ray spectromicroscopy techniques are emerging as useful tools to characterize potentially biocompatible materials and to probe protein interactions with model biomaterial surfaces. Simultaneous quantitative chemical analysis of the near surface region of the candidate biomaterial, and adsorbed proteins, peptides or other biological species can be obtained at high spatia...
متن کاملX-ray contact microscopy system for spectromicroscopy of biological specimens.
An X-ray contact microscopy system has been developed for the study of molecular and elemental distributions in biological specimens based on X-ray absorption characteristics. The system consists of a chamber for measuring XANES (X-ray absorption near-edge structure) of biomolecules, and a contact microscopy system for dried specimens with an electronic zooming tube. With this system the elemen...
متن کاملX-Ray Photoelectron Spectroscopy Enhanced by Machine Learning
X-Ray photoelectron spectroscopy (XPS) is a technique for identifying individual elements in a mixture/compound. Samples are irradiated by X-rays and the kinetic energy of ejected electrons is measured. Ejected electrons are captured by a spectrometer and measured intensities are plotted versus kinetic energy (Fig. 1). Each element appears as a series of peaks distributed as Gaussians/Lorentzia...
متن کاملCluster analysis of soft X-ray spectromicroscopy data.
Soft X-ray spectromicroscopy provides spectral data on the chemical speciation of light elements at sub-100 nm spatial resolution. When all chemical species in a specimen are known and separately characterized, existing approaches can be used to measure the concentration of each component at each pixel. In other cases (such as often occur in biology or environmental science), some spectral sign...
