The excited-state dynamics of covalently linked electron donor−acceptor systems consisting of N,N-dimethylaniline (DMA) as electron donor and either perylene (Pe) or cyanoperylene (CNPe) as acceptor has been investigated in a large variety of solvents, inc ...
The electrolytic cond. and soln. viscosity of some strong polycations, which possess the ammonium quaternary centers either attached to an acrylic macromol. chain (polycation PDMAEMQ type), or in the backbone (polycation PCA type), have been measured to id ...
Cyclosporin is a cyclic undecapeptide useful as drug for organ transplantation due to its immunosuppressive properties. Ten years ago, an anti-viral activity was discovered, incompatible with immunosuppression. These two activities originate in the presenc ...
The optical properties of mols. in complex environments were studied within hybrid time-dependent d. functional theory / mol. mechanics (TDDFT/MM) simulation studies. The potential energy surface in the excited state is described within time-dependent d. f ...

This thesis presents a comparative study of the ultrafast solvation dynamics of liquids in bulk conditions, and at the interfaces of metal-IV oxides (specifically TiO2 and ZrO2), using ultrafast spectroscopy techniques. In the first part of the thesis we r ...

Optical measurement techniques such as particle image velocimetry (PIV) and laser Doppler velocimetry (LDV) are now routinely used in experimental fluid mechanics to investigate pure fluids or dilute suspensions. For highly concentrated particle suspension ...

The fs-time-resolved study of a small UV dye in different solvents with fluorescence up-conversion and photon-echo techniques in the UV range provides new insight in cooling relaxation and solvation dynamics of non-polar molecules in polar solvents. ...

Hexofuranosides are widely spread in nature, and notably in numerous pathogenic microorganisms. This particular five-membered ring for hexosides leads to novel biological properties and, as usual in glycochemistry, to completely different reactivity and se ...

Without any claim of presenting scientific results, this article will present some reflections on different attitudes we can find in citizens towards their city. We categorised here two different behaviours that we connected to an active or passive role in ...
