TL;DR: This work uses femtosecond transient absorption spectroscopy to monitor the relaxation dynamics of single-layer MoS2 over the entire visible range, and finds that, irrespective of excitation photon energy, the transient absorption spectrum shows the simultaneous bleaching of all excitonic transitions and corresponding red-shifted photoinduced absorption bands.

TL;DR: In this article, the authors show that the third-order nonlinear susceptibility of Graphene can be increased by almost two orders of magnitude by controlling the Fermi energy and the incident photon energy.

TL;DR: Differences in the photocatalytic efficiencies are correlated with ultrafast transient absorption spectroscopy measurements, which show a faster bleach recovery for the PEI-coated hybrid nanoparticles, consistent with faster and more efficient charge separation.

TL;DR: The interplay between the many-body high-energy CuO2 excitations at 1.5 and 2 eV, and the onset of HTSC is reported, revealing an unconventional mechanism both below and above the optimal hole concentration required to attain the maximum critical temperature (Tc).
