Abstract Ultrafast photoinduced phase transitions at room temperature, driven by a single laser shot and persisting long after stimuli, represent emerging routes for ultrafast control over materials’ properties. Time-resolved studies provide fundam

Abstract We present experiments where extreme ultraviolet femtosecond light pulses are used to photoexcite large molecular ions at high internal energy. This is done by combining an electrospray ionization source and a mass spectrometer with a pulsed

Gas phase experiments combined with ultrafast technologies can provide information on the intrinsic properties of molecular systems at picosecond, femtosecond, or even attosecond timescales. However, these experiments are often limited to relatively

Pump-probe experiments in the gas phase usually target neutral molecules. Here the authors couple an electron spray source with ultrafast pump-probe UV-Vis spectroscopy, to follow the ππ*-πσ* coupling in tryptophan-based ions.

Transient absorption spectroscopy is used to identify the structural characteristics of the atoms and molecules. Here the authors used extreme ultraviolet transient absorption spectroscopy to identify the Rydberg state symmetry of aligned molecules.

Triggering new stable macroscopic orders in materials by ultrafast optical or terahertz pump pulses is a difficult challenge, complicated by the interplay between multiscale microscopic mechanisms, and macroscopic excitation profiles in samples. In p

We present a new experimental set-up combining ultrafast XUV technics with electrospray sources. First results of ultrafast dynamics in large molecular ions are shown demonstrating perspectives for applications in attochemistry.

Transient absorption spectroscopy is utilized extensively for measurements of bound- and quasibound-state dynamics of atoms and molecules. The extension of this technique into the extreme ultraviolet (XUV) region with attosecond pulses has the potent
L'Afrique est-elle vraiment mal partie? L'Afrique s'effondrera-t-elle? Ces interrogations légitimes et objectives, provenant des réflexions des penseurs africains comme Jean Marc Ela et Chinua Achebe trouvent une réponse dans le concept que l'aute
