Abstract. The review describes the application of nuclear magnetic resonance (NMR) spectroscopy to study kinetics folding, refolding and aggregation proteins, RNA DNA. Time-resolved NMR experiments can be conducted in a reversible or an irreversible manner. In particular, folding pose large requirements for (i) signal-to-noise due time limitations (ii) synchronising steps. Thus, this contributi...

A general theory is presented describing the photo-excitation dynamics of transient, paramagnetic triplet states aromatic molecules including their absorption properties in a molecular host crystal when irradiated by pulsed laser beam. It applied to system pentacene doped naphthalene single crystal, where results highly non-equilibrium population intermediate electronic states. These can be add...

We compute the vacuum polarisation correction to the binding energy of nuclear matter in the Walecka model using a nonperturbative approach. We first study such a contribution as arising from a ground state structure with baryon-antibaryon condensates. This yields the same results as obtained through the relativistic Hartree approximation of summing tadpole diagrams for the baryon propagator. S...

although the genome is defined by its primary sequence, its functional properties, are determined by far more complex mechanisms and depend on multiple layers of nuclear organization. the architecture of the nucleus includes two overlapping structures: the chromatin and a framework structure named the nuclear matrix. ultra-structural studies reveal that the nuclear matrix is a network consistin...

Electron-nuclear double resonance (ENDOR) is a method of choice to detect magnetic nuclei in the coordination sphere of paramagnetic molecules, but its sensitivity substantially suffers from saturation effects. Recently we introduced a new pulsed ENDOR experiment based on electron-nuclear cross polarisation (CP) transfer. Here we analyse the time evolution of the spin polarization in CP-ENDOR a...

We demonstrate a simple, scalable fabrication method for producing large-area arrays of vertically stacked metallic micro-rings, embedded in a deformable polymer sheet. Unusual polarisation-dependent hotspots are found to dominate the reflection images. To understand their origin, the arrays are characterized using point-scanning optical spectroscopy and directly compared to numerical simulatio...

At the magnetic fields of common NMR instruments, electron Zeeman frequencies are too high for efficient electron-nuclear dipolar cross-relaxation to occur in solution. The rate that process fades with frequency as omega^{-2} - absence isotropic hyperfine couplings, liquid state dynamic nuclear polarisation (DNP) high-field magnets is therefore impractical. However, contact coupling and not onl...
