DEER Data Analysis Software: A Comparative Guide

open access: yesFrontiers in Molecular Biosciences, 2022
Pulsed dipolar electron paramagnetic resonance (PDEPR) spectroscopy experiments measure the dipolar coupling, and therefore nanometer-scale distances and distance distributions, between paramagnetic centers.

Electron Paramagnetic Resonance in Biology

open access: yesBiophysical Journal, 1962
A review of the theories of electron paramagnetic resonance in biology is presented, including a discussion of the nature of the physical observation, followed by examples of materials of biological interest. Iq discussing these examples, information is presented in terms of the nature of the starting material under observation rather than the nature ...

Electron paramagnetic resonance of manganese-doped strontium titanate [PDF]

open access: yesCerâmica
Electron paramagnetic resonance (EPR) spectra of manganese-doped strontium titanate were investigated for several Mn concentrations. The spectra of Mn2+ and Mn4+ ions were observed and attributed, respectively, to Mn ions occupying Sr2+ and Ti4+ sites ...

Electron paramagnetic resonance of InP:Co

open access: yesJournal of Physics C: Solid State Physics, 1981
The electron paramagnetic resonance spectrum of cobalt in indium phosphide has been observed below 20K. An isotropic line at g=2.059(1) has been attributed to the one-electron trap Co2+.

Nanographene oxide-methylene blue as phototherapies platform for breast tumor ablation and metastasis prevention in a syngeneic orthotopic murine model

open access: yesJournal of Nanobiotechnology, 2018
Background In the photodynamic therapy (PDT), the photosensitizer absorbs light and transfers the energy of the excited state to the oxygen in the cell environment producing reactive oxygen species (ROS), that in its turn, may cause cell damage.

Electron paramagnetic resonance of VN–VGa complex in BGaN

open access: yesAPL Materials, 2023
A metastable photoinduced electron paramagnetic resonance (EPR) signal at low temperatures is reported for GaN alloyed with boron (i.e., BxGa1−xN) epitaxial layers grown at temperatures ranging from 840 to 1090° C. An isotropic EPR line with g = 2.004 is

Retrospective dosimetry using fingernail electron paramagnetic resonance response

open access: yesNuclear Engineering and Technology, 2018
Human fingernails were used to estimate the radiation dose via electron paramagnetic resonance measurements of radiation-induced radicals. The limiting factors in this research were mechanically induced electron paramagnetic resonance signals due to the ...

Synthesis and characterization of paramagnetic isotropic glycine manganese chloride single crystal with various dopant concentrations

open access: yesResults in Physics, 2019
Single crystals of α and γ glycine manganese chloride (GMC) were prepared using four dopant concentrations of MnCl2 in the molecular formula (C2H5NO2)1−x(MnCl2)x, where [x = 0.005, 0.02, 0.04, 0.05]. The crystals showed: nonlinear optical (NLO) activity,
