Identification of surfaces at the molecular level has benefited from progress in dynamic nuclear polarization surface enhanced NMR spectroscopy (DNP SENS).

The oxidation of thianisole and other substituted arylalkyl and diaryl sulfides with aqueous H 2 O 2 as the oxidant and heterogeneous TiO 2 catalyst exhibits a high selectivity affording the corresponding sulfones with 80-98% isolated yields. It should be noted that H 2 O 2 provided better results as compared with t BuOOH in terms of the reaction rate and yields of sulfones. The use of hydrogen peroxide and heterogeneous nanocrystalline titania catalyst is a green alternative to the traditional stoichiometric oxidation providing high yields of sulfones in one step.

Highly efficient and very stable iron and/or cobalt-based catalysts for the ammonia synthesis reaction were synthesized by one-step pyrolysis of metal phthalocyanine precursors.
