Study of the pO2-sensitivity of the dendrimeric and free forms of Pd-meso-tetra(4-carboxyphenyl)porphyrin, incorporated or not in chitosan-based nanoparticles

Hubert van den Bergh, Georges Wagnières, Peter Käuper, Patrycja Nowak-Sliwinska

The concentration of oxygen and its rate of consumption are important factors in certain medical treatments, such as radiotherapy and photodynamic therapy (PDT). Measuring the tissue concentration of oxygen or its partial pressure (pO2) can be achieved by ...

Long-Lived States to Monitor Protein Unfolding by Proton NMR

Geoffrey Bodenhausen, Aurélien Bornet, Paul Romeo Vasos, Riddhiman Sarkar, Puneet Ahuja

The relaxation of long-lived states (LLS) corresponds to the slow return to statistical thermal equilibrium between symmetric and antisymmetric proton spin states. This process is remarkably sensitive to the presence of external spins and can be used to ob ...

A Multitechnique Approach to Spin-Flips for Cp2Cr(II) Chemistry in Confined State

David Lyndon Emsley

Paramagnetic solid-state NMR, extended X-ray absorption fine structure (EXAFS), and Raman spectroscopies, along with detailed quantum mechanical calculations performed with different density functional theory (DFT) functionals, are successfully applied to ...

Multistability of a coherent spin ensemble in a semiconductor microcavity

Benoît Marie Joseph Deveaud, François Morier-Genoud, Taofiq Paraïso

Coherent manipulation of spin ensembles is a key issue in the development of spintronics. In particular, multivalued spin switching may lead to new schemes of logic gating and memories. This phenomenon has been studied with atom vapours 30 years ago, but i ...

Ni3TeO6-a collinear antiferromagnet with ferromagnetic honeycomb planes

Ivica Zivkovic, Helmuth Berger, Krunoslav Prsa

We report a comprehensive study of magnetic properties of Ni3TeO6. The system crystallizes in a noncentrosymmetric rhombohedral lattice, space group R3. There are three differently coordinated Ni atoms in the unit cell. Two of them form an almost planar ho ...

Ultrafast X-ray and Optical Spectroscopy of Binuclear Molecular Complexes

Renske Marjan van der Veen

In this thesis we followed the synergetic approach of combining ultrafast optical and X-ray spectroscopies to unravel the electronic and geometric structural dynamics of the solvated binuclear transition metal complex [Pt2(P2O5H2)4] 4- (PtPOP). This molecu ...

Applications of Long-Lived Spin States to High Resolution NMR Studies of Biomolecules

Puneet Ahuja

Slow dynamic processes, such as biomolecular folding/unfolding, macromolecular diffusion, etc., can be conveniently monitored by solution-state two-dimensional (2D) NMR spectroscopy, provided the inverse of their rate constants does not exceed the nuclear ...
