Atomic force microscopy was used to study the surfaces of oxygen-plasma-treated polypropylene (PP), kraft pulp, filter paper, and wood. The effect of plasma treatment on the adhesion properties between PP film and wood was evaluated by means of a pee

We have characterized electrically conductive polymer, polypyrrole (Ppy), films on mild steel with atomic force microscopy (AFM) and x-ray photoelectron spectroscopy (XPS). The Ppy films were polymerized electrochemically from sodium p-toluene sulpho

To clarify the mechanism of mercury adsorption on gold surfaces thin epitaxial gold films have been exposed to trace amounts of gaseous mercury under laboratory conditions for different periods of time. The changes in the surface morphology of the th

A new method for fabrication of reactive ion etching masks for nanoscale GaAs columns is proposed. The mask consists of sub‐100 nm Au islands formed by in situ heating a thin gold film on the substrate surface. The resulting areal density of the Au
