The laser-field-free elastic-scattering cross section of carbonyl sulfide was extracted from the measurements and is found in good agreement with previous experiments, performed using conventional electron diffraction.

Investigating the strong-field effects in the molecular frame allowed to add novel facets to the understanding of the intrinsic nature of strong-field physics..

These pulses constitute the shortest extreme ultraviolet pulses ever achieved via a time-delay compensated monochromator..

The measured spectrum extends from 210 to 340 nm, corresponding to a transform-limited pulse duration of 1.45 fs [...] OpenAccess: PDF PDF (PDFA); 2019-01-2811:38 [PUBDB-2019-00763] Journal Article et al Reconstruction of the time-dependent electronic wave packet arising from molecular autoionization Science advances 4(8), eaat3962 - (2018) [10.1126/sciadv.aat3962]   Autoionizing resonances are paradigmatic examples of two-path wave interferences between direct photoionization, which takes a few attoseconds, and ionization via quasi-bound states, which takes much longer. Time-resolving the evolution of these interferences has been a long-standing goal, achieved recently in the helium atom owing to progress in attosecond technologies [...] OpenAccess: PDF PDF (PDFA); 2019-01-1111:24 [PUBDB-2019-00394] Journal Article et al Solvent control of charge transfer excited state relaxation pathways in $\mathrm{[Fe(2,2′-bipyridine)(CN)_{4} ]^{2−}}$ Physical chemistry, chemical physics 20(6), 4238 - 4249 (2018) [10.1039/C7CP07838B]   The excited state dynamics of solvated $[Fe(bpy)(CN)_{4}]^{2−}$, where bpy = 2,2′-bipyridine, show significant sensitivity to the solvent Lewis acidity. Using a combination of optical absorption and X-ray emission transient spectroscopies, we have previously shown that the metal to ligand charge transfer (MLCT) excited state of $[Fe(bpy)(CN)_{4}]^{2−}$ has a 19 picosecond lifetime and no discernable contribution from metal centered (MC) states in weak Lewis acid solvents, such as dimethyl sulfoxide and acetonitrile.1,2 In the present work, we use the same combination of spectroscopic techniques to measure the MLCT excited state relaxation dynamics of $[Fe(bpy)(CN)_{4}]^{2−}$ in water, a strong Lewis acid solvent.

However, their photostability remains a practical bottleneck and further optimization is highly desirable.

Among them, blue-light-based devices are extremely limited because of the lack of a facile method to obtain high-purity $\mathrm{CsPbCl_{3}}$ NWs. [...] Restricted: PDF PDF (PDFA);
