The photochemical formation of a titan haze analog. Structural analysis by x-ray photoelectron and infrared spectroscopy
The photochemical flow reactor (D.W. Clarke et al., 2000, Icarus 147, 282–291) has been modified to minimize the incorporation of oxygen and other impurities in the photoproducts. A mixture of gasesExpand

Characterization of PdCl2/SnCl2 metallization catalysts on a polyetherimide surface by XPS and RBS
A metallization catalyst (based on the PdCl2/SnCl2 system) adsorbed on polyetherimide surfaces was characterized by x-ray photo-electron spectroscopy (XPS), Rutherford back scattering (RBS) andExpand

Interfacial reactions at copper surfaces coated with polyimide films prepared from poly(amide–acid) precursors
Thin films of polyimide were prepared by spin coating the poly(amide–acid) precursor onto copper and aluminum substrates, followed by the usual heat treatment to promote imidization (curing) of theExpand
