Self‐Accelerating Bimetallic Peroxide Nanozymes for Cascade‐Amplified Pyroptosis‐Immunotherapy

Advanced Science, EarlyView.
Acidic tumor microenvironment‐responsive CuZnONPs enable triple‐combination therapy via self‐supplying H2O2, cascade nanozyme activities for ROS burst, and Zn2+‐activated pyroptosis, synergizing catalytic therapy with immunotherapy to convert cold tumors into hot ones.

Development of an x-ray excited optical luminescence microscope (XEOM) [PDF]

X-ray excited optical luminescence (XEOL) refers to the trans-visible emission produced as a consequence of X-ray bombardment and provides an alternative detection method for X-ray absorption spectroscopy (XAS). Whereas XAS measured by conventional means

Orthogonal Design of Competing Deprotonation Process in Cation‐Mediated Ni(OH)2 for Achieving Industrial Level Biomass Electrooxidation

Advanced Science, EarlyView.
A Cu‐mediated Ni(OH)2 catalyst with orthogonal activity by precise valence engineering simultaneously accelerates rate‐determining aldehyde C─H activation in HMF oxidation and impedes O─H deprotonation in competing OER. This multi‐functional synergistic catalysis enables FDCA production at industrial‐level current densities without sacrificing FEFDCA ...

L3-edge X-ray spectroscopy of rhodium and palladium compounds

Journal of Synchrotron Radiation
L3-edge high-energy-resolution fluorescence-detection X-ray absorption near-edge structure (XANES) spectra for palladium and rhodium compounds are presented, with focus on their electronic structures. The data are compared with transmission XANES spectra

Dynamic multiple-scattering treatment of X-ray absorption: Parameterization of a new molecular dynamics force field for myoglobin

Structural Dynamics, 2018
We present a detailed analysis of the X-ray absorption near-edge structure (XANES) data on the Fe K-edge of CO Myoglobin based on a combined procedure of Molecular Dynamics (MD) calculations and MXAN (Minuit XANes) data analysis that we call D-MXAN.

Electronic structure effects on B K-edge XANES of minerals

, 2010
In order to assess the usability of X-ray absorption near-edge structure (XANES) for studying the structure of BOn-containing materials, the dependence of theoretical XANES at the B K-edge on the way the scattering potential is constructed is ...

Lunar‐Based Photothermal CO2 Reduction Strategy: Self‐Evolving Transient Active Interface and Band Engineering

Advanced Science, EarlyView.
A self‐evolving Pd/Ov‐FeTiO3 photothermal catalyst, inspired by lunar soil, enables efficient extraterrestrial CO2 conversion. The formation of transient active interfaces and oxygen vacancies extends light absorption to the infrared range and optimizes electron transfer.

Noise-robust analysis of X-Ray absorption near-edge structure based on poisson distribution

Science and Technology of Advanced Materials: Methods
We demonstrate that the noise tolerance of X-ray absorption near-edge structure (XANES) analysis can be improved by reconsidering the noise model. XANES measurement is a powerful technique to investigate the structure and electronic state of materials ...

Decision process for comparison of partial and complete XANES spectra

, 2010
Also published as: AIP Conference Proceedings, 2010; 1234(1):621-624If the range of XANES spectra varies between sets of scans, it may be impossible to compare sets of spectra unless a restricted part of the spectra is used.
