Spin phenomena in semiconductor quantum dots [PDF]

, 2013
This thesis discusses development of new semiconductor quantum dot (QD) devices and materials. Optical spectroscopy of single QDs is employed in order to investigate electronic structure and magnetic properties of these materials.

Defect Identification in Silicon Using Electron Nuclear Double Resonance

, 1985
The application of electron nuclear double resonance (ENDOR) for identification and characterization of point defects in silicon is reviewed. Taking the vacancy and the boron-vacancy complex as examples it is discussed how ENDOR can provide information ...

Aluminum and gallium nuclei as microscopic probes for pulsed electron-nuclear double resonance diagnostics of electric-field gradient and spin density in garnet ceramics doped with paramagnetic ions

AIP Advances, 2018
The presence of aluminum and gallium isotopes with large nuclear magnetic and quadrupole moments in the nearest environment of impurity ions Mn2+ and Ce3+ in garnets made it possible to use hyperfine and quadrupole interactions with these ions to ...

The interplay between spin densities and magnetic superexchange interactions: case studies of mono- and trinuclear bis(oxamato)-type complexes

Beilstein Journal of Nanotechnology, 2017
For future molecular spintronic applications the possibility to modify and tailor the magnetic properties of transition-metal complexes is very promising.

Overdense plasma heating in Wendelstein 7-X(W7-X) stellarator

Results in Physics, 2017
High yield nuclear fusion operating in tokamak and stellarator need to heat plasma up to the required temperatures. As the confined plasma is overdensed, the electron cyclotron resonance heating (ECRH) is inefficient due to cut-off layer.

Comparative Electron‐Nuclear Double Resonance Study of Two Flavoproteins [PDF]

European Journal of Biochemistry, 1970
The proton electron‐nuclear double resonance (ENDOR) of flavin radicals in NADPH dehydrogenase and a flavoprotein from Azotobacter vinelandii have been studied at −160 and −120°. By combination of the apoprotein of NADPH dehydrogenase with [8‐Me‐2H3]FMN, it was demonstrated that the CH3(8) group of the coenzyme gives an ENDOR signal.

Structural and biochemical analysis of a B12 superbinder

FEBS Letters, EarlyView.
BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

Study on resonant electron cyclotron heating by OSXB double mode conversion at the W7-X stellarator

Nuclear Engineering and Technology, 2018
Electromagnetic waves potentially have been used to heat overdense nuclear fusion plasmas through a double mode conversion from ordinary to slow extraordinary and finally to Electron Bernstein Wave (EBW) modes, OSXB.

Invisible but not inaccessible—Revealing transient oligomers formed by intrinsically disordered proteins with solution NMR and complementary methods

FEBS Letters, EarlyView.
Transient oligomers formed by intrinsically disordered proteins may be ‘invisible’ to direct detection yet remain accessible to solution NMR through equilibrium‐exchange measurements and pressure‐jump experiments. Complementary methods report on mass, stoichiometry, selected distance distributions, morphology, and internal packing.
