The entatic-state principle has been observed to apply to copper electron-transfer proteins and it results in a lowering of the reorganization energy of the electron-transfer process.

A series of CSQDs with a wide range of shell thicknesses was studied.

This work presents a detailed X-ray transient absorption (XTA) spectroscopy study of a prototypical spin crossover (SCO) complex [FeII(mbpy)$_3$]$^{2+}$ (where mbpy = 4,4′-dimethyl-2,2′-bipyridine) with an [Fe$^{II}$N$_6$] first coordination shell in water (H2$_O$) and acetonitrile (CH$_3$CN).

With two-photon excitation, red-shifted PL spectrum and increased PL lifetime is observed compared with one-photon excitation.

Photoemission delay: The White Rabbit's clock Nature physics 13(3), 207 – 208 (2016) [10.1038/nphys3973]   Without a very precise timer one can never catch up with the electron released in photoemission. Attosecond streaking spectroscopy allows such a chronometer clock to be set to zero and reveals the role of electron correlations..

In the present study, the damage caused by energetic particles was simulated by measuring the action of extreme ultraviolet (XUV) attosecond pulses on the DNA building blocks thymine and thymidine [...] 2017-12-3019:11 [PUBDB-2017-14151] Journal Article et al Attosecond streaking metrology with isolated nanotargets Journal of optics 20, 0024002 (2017) [10.1088/2040-8986/aa9b08]   The development of attosecond metrology has enabled time-resolved studies on atoms, molecules, and (nanostructured) solids. Despite a wealth of theoretical work, attosecond experiments on isolated nanotargets, such as nanoparticles, clusters, and droplets have been lacking.

So far, single-shot single-particle diffraction was assumed to be feasible only at extreme ultraviolet and X-ray free-electron lasers, restricting this research field to large-scale facilities.

Maximizing the signal-to-noise ratio of the measurements is often a primary need of the experiment, and the aggregation of repeated, rapid, scans of the pump-probe delay is preferable to a single long-lasting scan.
