Increased sensitivity in electron–nuclear double resonance spectroscopy with chirped radiofrequency pulses [PDF]

open access: yesMagnetic Resonance
Electron–nuclear double resonance (ENDOR) spectroscopy is an EPR technique to detect the nuclear frequency spectra of hyperfine coupled nuclei close to paramagnetic centers, which have interactions that are not resolved in continuous wave EPR spectra and

EPR spectroscopy reveals antioxidant manganese defenses in the Lyme disease pathogen Borrelia burgdorferi [PDF]

open access: yesmBio
Oxidative stress defense in aerobic bacteria relies on Mn-superoxide dismutase (MnSOD) and antioxidant Mn-metabolite complexes (H-Mn) to quench superoxide radicals (O2•−).

Aerodynamic Optimization Design of a Supersonic Compressor Rotor with High Pressure Ratio

open access: yesInternational Journal of Aerospace Engineering, 2021
Supersonic compressors have a high wheel speed and operational capability, which facilitate a high stage pressure ratio. However, the strong shock waves in the passage of a supersonic rotor and the interference between shock waves and boundary layers can

A primer in pulse EPR-based hyperfine spectroscopy for NMR spectroscopists

open access: yesJournal of Magnetic Resonance Open, 2023
The theoretical foundations of NMR and EPR are very similar. Nevertheless, the fields differ significantly in practical aspects. This primer is an attempt to bridge some of the gaps between the fields, and at the same time it highlights some applications

Cross-polarisation edited ENDOR [PDF]

open access: yesMolecular Physics, 2013
Electron-nuclear double resonance (ENDOR) is a fundamental technique in electron paramagnetic resonance (EPR) spectroscopy that directly detects hyperfine transitions of nuclei coupled to a paramagnetic centre. Despite its wide use, spin-sensitivity and restricted spectral resolution in powder samples pose limitations of this technique in modern ...

Electron nuclear double resonance study of photostimulated luminescence active centers in CsBr:Eu2+ medical imaging plates [PDF]

open access: yes, 2011
CsBr:Eu2+ needle image plates exhibit an electron-paramagnetic-resonance (EPR) spectrum at room temperature (RT), whose intensity is correlated with the photostimulated luminescence sensitivity of the plate.
