Core-level spectra and molecular deformation in adsorption: V-shaped pentacene on Al(001)
By first-principle simulations we study the effects of molecular deformation on the electronic and spectroscopic properties as it occurs for pentacene adsorbed on the most stable site of Al(001).

Photochemistry of Aromatic N‐Oxides in Water Probed by Time‐Resolved X‐ray Absorption Spectroscopy
Time‐resolved XAS at the nitrogen and oxygen K‐edges is applied to the photorearrangement of two N‐oxides in water. Pyridine N‐oxide rapidly forms the oxaziridine isomer. Pyridazine N‐oxide undergoes ring opening to the diazo compound, without any evidence of intermediates.

Spherulite in the modern aragonitic travertine stromatolite has a calcite core with exopolymers
ABSTRACT Spherulites are spherical to ellipsoidal particles formed by various crystalline substances and can be abiotically synthesised in the laboratory. Among various spherulite types, spherulites composed of calcium carbonate are also found in various natural environments, but their abiotic or biotic origins are still controversial.

The molecular orientation is crucial for the efficiency of organic solar cells. A face-on orientation, in which the $\pi - \pi $ stacking direction is oriented perpendicular to the substrate, is typically preferred because it enhances vertical charge ...

Influence of bond defects on coiling of graphite
The effect of annealing at 1400 °C in argon on the bond structure of graphite ball milled for 100 h at 400 rpm in polar (water) and in non-polar (n-dodecane) liquids was investigated primarily by near-edge X-ray absorption fine structure spectroscopy ...
