In Situ Formation of a Highly Selective Nickel Single Atom Catalyst for Electrochemical CO2 Reduction to CO

Advanced Materials, EarlyView.
Development of a novel method for synthesizing Ni single atom catalysts for highly selective electrochemical CO2 reduction in situ. This catalyst achieves 100% selectivity for CO and is formed in an industrially relevant cell architecture. Using post‐mortem XRD, STEM, and EDS and operando XAS, the identity of the active site and the mechanism behind ...

Decoupling the metal insulator transition and crystal field effects of VO2

Scientific Reports, 2021
VO2 is a highly correlated electron system which has a metal-to-insulator transition (MIT) with a dramatic change of conductivity accompanied by a first-order structural phase transition (SPT) near room temperature.

XAFS in a single macrophage cell

Journal of Synchrotron Radiation, 2001
In this paper, a novel approach using XAFS will be introduced for the study of the problem of cytotoxicity to metal ions. A micro beam from a SR source was used to measure the time-dependent distributions and chemical states of elements in mouse microphages that were cultured in metallic solutions of different concentration.

Where Precursor Loading Stops Making a Difference: Resolving an Operational Infiltration Limit for Nanoparticle Synthesis Using Dual Quantification of Reverse Micelle Nanoreactors

Advanced Materials Interfaces, EarlyView.
A dual characterization strategy combining nanomechanical and mass measurements resolves a common operational loading threshold in reverse micelle nanoreactors. This transferable framework provides a rational strategy for optimizing precursor loading and nanoparticle synthesis, across template‐mediated fabrication systems.

Amphiphilic Non‐Isocyanate Polyurethane Coatings With Tunable Antifouling and Fouling‐Release Performance: A Log‐Ratio Assessment Framework

Advanced Materials Interfaces, EarlyView.
Amphiphilic non‐isocyanate polyurethane (NIPU) coatings containing reactive hydrophobic poly(dimethylsiloxane) (PDMS) and hydrophilic methoxy poly(ethylene glycol) (MPEG) prepolymers for marine antifouling (AF) and fouling‐release (FR) applications were investigated. The coatings were evaluated with a set of representative marine foulants.

XAFS investigations of tin nitrides

Journal of Synchrotron Radiation, 2001
Tin nitrides (Sn3N4) prepared by the reaction of Sn-halides with KNH2 in liquid ammonia and a subsequent vacuum annealing procedure were investigated with transmission mode XAFS experiments. While the near edge data suggest the presence of a univalent Sn-compound with a valency close to +4, the analysis of the extended X-ray absorption fine structure ...

Atomic Tuning of Metal‐Support Interactions for Pathway‐Selective CO2 Photoreduction on TiO2

Advanced Science, EarlyView.
Single‐atom Fe and Cu catalysts anchored on TiO2 steer photocatalytic CO2 reduction toward distinct pathways. Fe sites favor rapid *CO desorption and selective CO formation, whereas Cu sites stabilize *CHO intermediates, enabling deep reduction and C─C coupling. Combined spectroscopy and DFT calculations reveal how metal–support interactions and oxygen
