Electrochemical "switching" of Si(100) modular assemblies
MetadataShow full item record
We report on a modular approach for producing well-defined and electrochemically switchable surfaces on Si(100). The switching of these surfaces is shown to change a Si(100) surface from resistant to cell adsorption to promoting cell adhesion. The electrochemical conversion of the modified electrode surface is demonstrated by X-ray photoelectron spectroscopy, X-ray reflectometry, contact angle and cell adhesion studies.

Relationship between surface concentration of l-leucine and bulk powder properties in spray dried formulationsMangal, S.; Meiser, F.; Tan, G.; Gengenbach, T.; Denman, J.; Rowles, Matthew; Larson, I.; Morton, D. (2015)The amino acid l-leucine has been demonstrated to act as a lubricant and improve the dispersibility of otherwise cohesive fine particles. It was hypothesized that optimum surface l-leucine concentration is necessary to ...
