Heterogeneous phase astrochemistry plays an important role in the synthesis of complex organic matter (COM) as found on comets and rocky body surfaces like asteroids, planetoids, moons and planets. The proposed catalytic model is based on two assumpt

Cosmic siliceous dust grains are involved in the synthesis of H2 in the inter-stellar medium. In this work, the dust grain siliceous surface is represented by a hydrogen Fe-metalla-silsesquioxane model of general formula: [Fe(H7 Si7 O12-n )(OH)n ]+ (

Transition metals (TMs) are proposed to play a role in astrophysical environments in both gas and solid state astrochemistry by co-determining the homogeneous/heterogeneous chemistry represented by the gas-gas and gas-dust grain interactions. Their c

An EGFP construct interacting with the PIB1000-PEG6000-PIB1000vesicles surface reported a ~2-fold fluorescence emission enhancement. Because of the constructs nature with the amphiphilic peptide inserted into the PIB core, EGFP is expected to experie
