X-Band Rapid-Scan EPR
<p>The advantages of rapid-scan EPR relative to CW and pulse techniques for samples with long longitudinal relaxation time T<sub>1</sub> (N<sub>s</sub><sup>0</sup> defects in diamond, N@C<sub>60</sub>, and amorphous hydrogenated silicon), heterogeneous samples (crystalline 1:1 …

Rapid Scan Electron Paramagnetic Resonance (EPR) and Digital EPR Development
<p>Rapid scan electron paramagnetic resonance (EPR) was developed in the Eaton laboratory at the University of Denver. Applications of rapid scan to wider spectra, such as for immobilized nitroxides, spin-labeled proteins, irradiated tooth and fingernail samples were demonstrated in this …

Electron Spin Echo and Millimeter Wave Epr Studies of Disordered Solids
… continuous wave electron paramagnetic resonance (cw EPR) techniques are better suited to study strong short range ($$35 GHz) experiments should result in enhanced resolution or allow for more accurate determinations of the zero-field splitting energies in a high spin system. Single crystal spectra …

Development of dermally absorbed copper(ii) complexes as potential anti-inflammatory drugs
… studied using UV-Vis spectrophotometry, CW-EPR spectroscopy, 1H NMR, ESI-MS and molecular modelling calculations. The presence of sarcosine did not significantly affect the stability of the complexes. Several species were found to exist in solution depending on the pH, but at pH 7, the …

Templating Metal Clusters via Resorcinarene- and Cyclen- Based Ligand Platforms
… by the nitrogenase enzyme, which offers a blueprint for sustainable alternatives to the energy-intensive Haber-Bosch process. Additionally, the Nitrous Oxide reductase presents a Cuz/Cuz* site that facilitates the reduction of Nitrous Oxide to environmentally benign forms. At the heart of …

Studies on the structure, function and mechanisms of the cbb3 type cytochrome c oxidase from Vibrio cholerae and the cytochrome bo3 ubiquinol oxidase from Escherichia coli
… formation and Y173 is crucial for F formation. CW-EPR experiments demonstrated WT and Y288H generated a radical of the same origin while Y173 gave rise to a different radical species and Y288H+Y173F failed to generate radical of any kind. Auxotrophic strains were made for every mutant. We found …

Biochemical characterization of a-type heme-copper oxidases in escherichia coli, bacillus subtilis and thermus thermophilus
… and quinone binding site was examined using EPR spectroscopy. Overall, the hyperfine coupling shows difference between ubiquinone and menaquinone semiquinone with quinone binding site in cytochrome bo3, suggesting different binding geometry. Three nitrogens were indicated interacting with …
