Dynamics of geminate recombination of NO with myoglobin in aqueous solution probed by femtosecond mid-IR spectroscopy

Article Abstract:

The dynamics of nitric oxide (NO) rebinding to Mb and its model system, microperoxidase, in D2O solution at 283 K after photolysis was directly observed by monitoring the stretching mode of NO using time-resolved IR spectroscopy is accurately determined. The transient spectra of photolyzed MbNO reveal two overlapping vibrational bands for bounds NO 1598 and 1611 cm(super -1).

On the role of different adsorption and reaction sites on supported nanoparticles during a catalytic reaction: NO decomposition on a Pd/Alumina model catalyst

Article Abstract:

The catalytic decomposition of NO on a structurally well-defined Pd model catalyst is studied by employing a combination of molecular beam techniques and time-resolved absorption spectroscopy (TR-IRAS). The study concluded by investigating the role of different adsorption and reaction sites on a structurally well-defined Pd/alumina model catalyst.

N20 decomposition on TiO2 (110) from dynamic first-principles calculations

Article Abstract:

Two different mechanisms for N2O decomposition on defective TiO2 (110) were elucidated and were related to experimental findings. The role of the metal oxide surface is identified as a provider of electrons and pointed out the fact that, from a methodological point of view, dynamical effects are essential.
