Tailoring High‐Valent Iron‐Oxo Species Redox via Extended π‐Fe3d–O2p Orbital Overlapping Toward Chemical‐Efficient Water Purification

Angewandte Chemie, EarlyView.
We address the long‐standing challenge of reactivity–selectivity trade‐off by precisely tuning the redox properties of Fe(IV), rather than simply accelerating its formation, to enable chemically efficient and low‐emission water treatment. ABSTRACT High‐valent iron oxo species (Fe(IV)) are attractive for wastewater treatment because of their high ...

Acceptor‐Doped Cerium Oxides Enabling Metallic Nanocatalyst Exsolution for Hydrogen Production From Ammonia

Angewandte Chemie, EarlyView.
Outstanding catalytic results for NH3 decomposition for H2 production were obtained with metallic Ru, Rh, and RuRh nanoparticle‐exsolved CeO2‐based catalysts. Significant lower amounts of available superficial metallic fractions were needed in comparison to conventional Ru‐impregnated materials.

In‐Cell NMR and EPR Spectroscopy of Biomacromolecules

Angewandte Chemie - International Edition, 2014
AbstractThe dream of cell biologists is to be able to watch biological macromolecules perform their duties in the intracellular environment of live cells. Ideally, the observation of both the location and the conformation of these macromolecules with biophysical techniques is desired.

EPR Spectroscopy in Catalysis

2011
The modern chemical industry relies heavily on homogeneous and heterogeneous catalysts. Understanding the operational mode, or reactivity, of these catalysts is crucial for improved developments and enhanced performance. As a result, various spectroscopic techniques are inevitably used to characterize and interrogate the mechanistic details of the ...

EPR Spectroscopy

2022
EPR spectroscopy is a versatile, nondestructive technique widely used in chemistry, biology, and physics. It detects molecules and materials with unpaired electrons making it a very selective technique that produces a wealth of information on such systems.

EPR spectroscopy of semi-methemerythrin

Biochimica et Biophysica Acta (BBA) - Protein Structure, 1980
EPR spectra of semi-met forms of octameric hemerythrin from Themiste zostericola, prepared by one electron reduction of methemerythrin or by one electron oxidation of deoxyhemerythrin, have been visualized at liquid helium temperatures. The spectrum of that prepared by one electron reduction has principal g-values of 1.96 +/- 0.01, 1.88 +/- 0.01, and 1.
