Molecularly tunable "Organic Capacitors" at silicon/aqueous electrolyte interfaces

Article Abstract:

Organic modification of oxide-free silicon surfaces offers a direct combination of molecular materials and solid-state semiconductor structures, making it an attractive approach to provide technologically useful and molecularly tunable thin films. The fabrication and characterization of these organic thin films covalently bound to silicon surfaces promise to improve the stability toward oxidation and to maintain satisfactory electrical properties of silicon electrodes.

Conformation of an alkane chain in confined geometry: cetyl trimethyl ammonium ion intercalated in layered CdPS(sub 3)

Article Abstract:

Intercalation occurs with a lattice expansion of 4.8 angstrom with the methylene "tail" of the intercalated surfactant lying closer to the walls of galleries, rather than in the center. Extensive theoretical and experimental studies of ultrathin films of oligomeric hydrocarbons confined between atomically smooth surfaces report remarkable differences in static and dynamic properties from those of the bulk.

A cationic rubidium continuum in zeolite X

Article Abstract:

Zeolites exposed to alkali metal vapor can sorb metal atoms into their cavities to form cationic clusters. The synthesis and characterization of supersmall clusters have drawn increased attention from a variety of research fields, such clusters have application in heterogeneous catalysis as well as in advanced magnetic, optical, and electronic materials.
