Substrate and solution effects on the long-Range "Hydrophobic" interactions between hydrophobized gold surfaces
Article Abstract:
Hydrophobic surfaces prepared by adsorption of hexadecanethiol, 1,10-dithiodecane, octadecanoic acid, and hexadecanol onto gold with the use long-range "hydrophobic" interactions are studied and direct-force measurements in water, aqueous NaCl electrolytes, and water/ethanol mixtures, using a bimorph surface force instrument are performed. The contact angle is sufficient to predict the presence of an attraction in excess of van der Waals forces for very stable hydrophobic surfaces in which case the attraction is caused by the coalescence of microscopic bubbles on the surfaces is confirmed.

Combing and bending of carbon nanotube arrays with confined microfluidic flow on patterned surfaces
Article Abstract:
It is demonstrated that a wet-chemistry approach can be used to produce a massive amount of textured nanotube fabrics or nanotube loops of different shapes assembled in ordered, robust arrays on the patterned silicon wafer surface. The orientation and bending mechanisms are facilitated by the pinning of the carbon nanotubes predominantly tethered to the functionalized surface by their carboxylic end groups.

Enhanced vibrations at surfaces with back-Bonds nearly parallel to the surface
Article Abstract:
A class surface structure is identified in which usually large vibration amplitudes were detected with low-energy electron diffraction (LEED). The study suggested that theory examines and confirms the cause of enhanced surface vibration amplitudes and explore its implications for other phenomena such as adsorption and catalysis.
