Adsorption characteristics of anthraquinone-2-carboxylic acid on gold
Article Abstract:
The adsorption rate of anthraquinone-2-carboxylic acid (AQ-2-COOH) on gold was, however, much slower than that on silver as well as the adsorption strength to gold being considerably weaker than to silver. Reflection-adsorption infrared (RAIR) spectral data revealed that AQ-2-COOH was chemisorbed on gold as carboxylate, after deprotonation, with its two oxygen atoms bound symmetrically to the metal substrate.

Adsorption characteristics of 1,3-propanedithiol on gold: surface-enhanced Raman scattering and ellipsometry study
Article Abstract:
The adsorption behavior of 1,3-propanedithiol (1,3-PDT) on a colloidal gold surface is investigated by means of surface-enhanced Raman scattering (SERS). The study discuses that a separate ellipsometry measurement revealed that a best one and one-half layered film could be assembled on gold in polar and protic solvents while up to three layers were assembled on gold in n-hexane solution of 1,3-PDT.

Oxygen adsorption on the (110)-oriented diamond surface
Article Abstract:
The interaction of oxygen with a diamond (110)-oriented surface is investigated y using multiple internal reflection infrared spectroscopy (MIRIS) and temperature-programmed desorption (TPD). The observation implies that the low-temperature adsorption sites were etched away, thus favoring the additional adsorption of oxygen sites that are stable at high temperature.
