Development and Application of THz Gyrotrons for Advanced Spectroscopic Methods

open access: yesPhotonics, 2023
Nowadays, gyrotrons are used in numerous and diverse fields of research and technology. Their most prominent application is to electron cyclotron resonance plasma heating and current drive-in reactors for controlled thermonuclear fusion.

Interaction-induced adiabatic non-linear transport [PDF]

open access: yes, 2010
We calculate the time-dependent non-linear transport current through an interacting quantum dot in the single-electron tunneling regime (SET). We show that an additional dc current is generated by the electron-electron interaction by adiabatic out-of ...

High-spin Metal Centres in Dipolar EPR Spectroscopy

open access: yesCHIMIA, 2018
The substitution of Mg2+ by Mn2+ in the bacterial DnaB helicase from Helicobacter pylori, an ATP:Mg2+-fuelled protein engine, allows electron paramagnetic resonance (EPR) spectroscopy to be performed on this system.

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

Electron paramagnetic resonance spectroscopy using a dc-SQUID magnetometer directly coupled to an electron spin ensemble

open access: yes, 2015
We demonstrate electron spin polarization detection and electron paramagnetic resonance (EPR) spectroscopy using a direct current superconducting quantum interference device (dc-SQUID) magnetometer.

Mechanisms for the Direct Electron Transfer of Cytochrome c Induced by Multi-Walled Carbon Nanotubes

open access: yesSensors, 2012
Multi-walled carbon nanotube (MWCNT)-modified electrodes can promote the direct electron transfer (DET) of cytochrome c (Cyt c). There are several possible mechanisms that explain the DET of Cyt c.

Exploring Intrinsically Disordered Proteins using Site-Directed Spin Labelling Electron Paramagnetic Resonance spectroscopy

open access: yesFrontiers in Molecular Biosciences, 2015
Proteins are highly variable biological systems, not only in their structures but also in their dynamics. The most extreme example of dynamics is encountered within the family of Intrinsically Disordered Proteins (IDPs), which are proteins lacking a well-

OOP-ESEEM Spectroscopy: Accuracies of Distances of Spin-Correlated Radical Pairs in Biomolecules

open access: yesFrontiers in Molecular Biosciences, 2022
In addition to the commonly used electron–electron double resonance (ELDOR) technique, there are several other electron paramagnetic resonance (EPR) methods by which structure information can be obtained by exploiting the dipolar coupling between two ...

Electric excitation of spin resonance in antiferromagnetic conductors

open access: yes, 2009
Antiferromagnetism couples electron spin to its orbital motion, thus allowing excitation of electron-spin transitions by an ac electric rather than magnetic field - with absorption, exceeding that of common electron spin resonance at least by four orders

An in situ spectroelectrochemical study of the dimeric phthalocyanines [(SiPc)2O][OSiHx3]2, [(SiPc)2O][OSiHx3]2·+, and [(SiPc)2O][OSiHx3]22+

open access: yesElectrochemistry Communications, 2021
An in situ spectroelectrochemical study of the oxidation of the μ-oxosilicon phthalocyanine dimer [(SiPc)2O][OSiHx3]2 utilizing cyclic voltammetry, electron spin resonance spectroscopy, and visible–near infrared spectroscopy has been carried out.
