Preparation of High Purity Mullite Ceramics

Laboratory for preparation of high-purity clinical chemicals.

A laboratory is described for the preparation and analysis of high-purity clinical chemicals. The work area is designed to minimize contact of high-purity materials with the main source of contamination, the chemical operator. We discuss the use of a perforated, curved, anodized aluminum membrane that permits completely free access to the work area and describe the general construction of the l...

Materials Development for Next Generation Optical Fiber

Optical fibers, the enablers of the Internet, are being used in an ever more diverse array of applications. Many of the rapidly growing deployments of fibers are in high-power and, particularly, high power-per-unit-bandwidth systems where well-known optical nonlinearities have historically not been especially consequential in limiting overall performance. Today, however, nominally weak effects,...

Module 2 - Optical Fiber Materials

Dr. B.G.Potter is a Professor of Material Science and Engineering in the University of Arizona. Research activity within Dr. Potter's group is centered on the synthesis and study of glass, ceramic, and molecular hybrid materials for photonic and electronic applications. Active research and ongoing programs include: optically driven molecular assembly strategies, nanostructured photovoltaic ener...
