The solid state photochemistry and photophysics of a triphenylmethyl dye cyanide

Creator:

Vernier, David L.

Abstract:

Triphenylmethyl dye cyanides have been known to be sensitive to ultraviolet radiation since early in this century. Under appropriate conditions, exposure to uv leads to heteropolar fission of the C-CN bond (photoionization) and intense coloration due to dye formation. Thin homogeneous films of hexahydroxyethyl pararosaniline cyanide in a nylon matrix...

Some aspects of the sulfur cycle in tidal flat areas, and their impact on estuarine water quality

Creator:

Ramm, Alan Edmund

Abstract:

A conceptual model of the tidal flat system, emphasizing the sulfur cycle was presented. Measurements were made of the vertical distribution within tidal flat deposits of total aerobic and sulfate reducing bacteria, total sulfides, redox potential, volatile solids, and particle size. Variations in dissolved oxygen and free sulfides in the...
