Characterization 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 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...
متن کاملX-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 کاملX-ray spectromicroscopy investigation of soft and hard breakdown in RRAM devices.
Resistive random access memory (RRAM) is considered an attractive candidate for next generation memory devices due to its competitive scalability, low-power operation and high switching speed. The technology however, still faces several challenges that overall prohibit its industrial translation, such as low yields, large switching variability and ultimately hard breakdown due to long-term oper...
متن کاملIn Situ Soft X-ray Spectromicroscopy of Early Tricalcium Silicate Hydration
The understanding and control of early hydration of tricalcium silicate (C₃S) is of great importance to cement science and concrete technology. However, traditional characterization methods are incapable of providing morphological and spectroscopic information about in situ hydration at the nanoscale. Using soft X-ray spectromicroscopy, we report the changes in morphology and molecular structur...
