The passive state of chromium has been examined in 1 M H 2 SO 4 by a variety of electrochemical techniques and x‐ray photoelectron spectroscopy. The potentiodynamic behavior of the passive electrode may be described by high‐field film growth kinetics. The passivating oxide film is 5–25 Å thick and consists of chromic…
To examine the mechanism of film deposition in a planar rf CH4 discharge plasma, measurements were made of the spatial distributions of the deposition rate and optical emission intensity along the discharge axis between parallel electrodes. Optical-absorption properties of the deposited carbon films were also measured…
The suitability of polymeric biomaterials as surfaces for the attachment and growth of cells has often been investigated in tissue culture. In this study the contribution that adsorption of serum fibronectin (Fn) or vitronectin (Vn) make to the attachment and spreading of fibroblast cells during the first 90 min follo…

Duplex (two‐phase) microstructures and laminar composites offer some unique opportunities for improving the room‐temperature mechanical reliability (e.g., flaw tolerance) and the high‐temperature microstructural stability (e.g., resistance to grain growth and creep damage) of structural ceramic materials. Examples ill…

Low energy electron diffraction (LEED) has been used to study the effects of atomic and molecular species of hydrogen and oxygen on the reconstructed C(100)-(2×1) surface. Thermal desorption spectroscopy was also used to study desorption products and kinetics from hydrogenated and oxygenated surfaces. Atomic hydrogen…
