Abstract The electronic and optical properties of graphene are greatly dependent on the the number of layers. For the precise control of the graphene layers, atomic layer etching (ALE), a cyclic etching method achieved through chemical adsorption and

Monitoring early-stage β-amyloid (Aβ) dimerization is a formidable challenge for understanding neurological diseases. We compared β-sheet formation and histidine site-specific two-dimensional infrared (2D IR) spectroscopic signatures of Aβ dimers

The ultrafast photoinduced chirality loss of 2-iodobutane is studied theoretically by time- and frequency-resolved X-ray circular dichroism (TRXCD) spectroscopy. Following an optical excitation, the iodine atom dissociates from the chiral center, whi

In the current study, we present nonadiabatic (NAMD) and adiabatic molecular dynamics simulations of the transition-state dynamics of photoexcited cyclooctatetraene (COT). The equilibrium-state structure and absorption spectra are analyzed using the

Nitrogen/fluorine doping of TiO2 nanoparticles (NPs) serves to play an important role with regard to visible light absorption and charge carrier dynamics. However, it is largely unknown how nitrogen/fluorine doping retards electron–hole recombinati

We theoretically monitor the photoinduced ∗ → n∗ internal conversion process in 4-thiouracil (4TU), triggered by an optical pump. The element-sensitive spectroscopic signatures are recorded by a resonant X-ray probe tuned to the sulfur, oxygen,

Organic magnetic materials must possess sufficient magnetic coupling to realise their potential. Most coupling studies were based on intramolecular modifications because the molecular structure ultimately dictates the molecule's properties. In this s
