XPS film thickness and adsorption studies of alkyltrimethylammonium bromides and organosilanes on silica surfaces

Kinetic and mechanistic study of CO2 corrosion inhibition by cetyl trimethyl ammonium bromide

“…The peak at 402-403 eV was found in the spectra of the three specimens exposed to the CTAB solution, but was absent in the spectrum of the one removed before CTAB addition. This peak may be assigned to the N 1s energy of adsorbed CTAB, since it is close to the value of 402 eV reported for CTAB adsorbed on silver bromide [32] and quarts [33]. A second nitrogen peak (397-398 eV) appeared for the 19 and 96 h specimens.…”

Synthesis of magnetic and fluorescent multifunctional hollow silica nanocomposites for live cell imaging

“…The N1s peak is now at 402.8 eV. This value is slightly higher that for pure CTAB (402 eV), indicative of the interaction between CTAB and the nanoparticles surface [50,51]. As shown in Fig.…”

Adsorption of organic molecules on silica surface

“…The elemental nature of surface can be characterized by Xray photoelectron spectroscopy [310][311][312] and augur spectroscopy [313], and its chemical state can be viewed through valence level photoemission spectra and molecular vibrational spectra. Similarly vibrational spectroscopy can be used to study local ordering while diffraction method can be used to study long range ordering.…”
