Journal ArticleDOI
Influence of surface oxides on the adsorption of naphthalene onto multiwalled carbon nanotubes.
TL;DR: Sorption data are consistent with the idea that incorporated surface oxides create polar regions that reduce the surface area available for naphthalene sorption, and highlight the important role of surface chemistry in controlling the environmental properties of CNTs.
Journal ArticleDOI
Electron Induced Surface Reactions of the Organometallic Precursor Trimethyl(methylcyclopentadienyl)platinum(IV)
Joshua D. Wnuk,Justin M. Gorham,Samantha G. Rosenberg,Willem F. van Dorp,Theodore E. Madey,Cornelis W. Hagen,D. Howard Fairbrother +6 more
TL;DR: In this paper, the effect of 500 eV electrons on nanometer scale thin films of trimethyl(methylcyclopentadienyl)platinum(IV) (MeCpPtIVMe3), were studied in situ, under ultrahigh vacuum conditions using a combination of temperature-programmed desorption (TPD), X-ray photoelectron spectroscopy (XPS), mass spectrometry, and reflection absorption infrared spectroscope.
Journal ArticleDOI
Electron induced dissociation of trimethyl (methylcyclopentadienyl) platinum (IV): Total cross section as a function of incident electron energy
W. F. van Dorp,W. F. van Dorp,Joshua D. Wnuk,Justin M. Gorham,D. H. Fairbrother,Theodore E. Madey,Cornelis W. Hagen +6 more
TL;DR: In this paper, the total cross section of trimethyl (methylcyclopentadienyl) platinum (IV) [MeCpPt(IV)Me3], a Pt precursor often used in focused electron beam induced processing (FEBIP), for incident electron energies ranging between 3-3 keV.
Journal ArticleDOI
Electron beam irradiation of dimethyl-(acetylacetonate) gold(III) adsorbed onto solid substrates
Joshua D. Wnuk,Justin M. Gorham,Samantha G. Rosenberg,Willem F. van Dorp,Theodore E. Madey,Cornelis W. Hagen,D. Howard Fairbrother +6 more
TL;DR: In this article, an ultrahigh vacuum-surface science approach was employed to study the electron induced reactions of dimethyl-(acetylacetonate) gold(III) [AuIII(acac)Me2] adsorbed onto solid substrates.
Journal ArticleDOI
Multielectron Transfer at Heme-Functionalized Nanocrystalline TiO2: Reductive Dechlorination of DDT and CCl4 Forms Stable Carbene Compounds
TL;DR: The spectroscopic data are fully consistent with a dissociative two-electron organohalide reduction mechanism of CCl4 and DDT to yield (protoporhyrinato)FeIICCl2 and ( protoporHyrinatos) FeIIC=C(p-Cl-phenyl)2 respectively.
