The Houston program on glasses and liquids has continued over the year with an expanded activity into vitreous TiO/sub 2/ and amorphous metals/quasicrystals. The modeling study of vitreous SiO/sub 2/ has been published and the study of amorphous melanin is well underway in-house. We have also begun some promising modeling work on the icosahedral glass model (IGM) for quasicrystals and have completed a preliminary study of epitaxial diamond crystal growth on the (111) silicon crystal surface (initially undertaken to study the expected ''amorphous'' diamond-like phase). The work on GLAD at the Argonne IPNS continues on schedule under the direction of Dr. David L. Price. The status of the Phase I instrument has been published and the Phase II development is underway with an evacuated flight path, additional detectors and a final data acquisition system in progress. It is our expectation that the final instrument will be the most advanced of its kind in the world for the study of a wide variety of problems in glasses, liquids and amorphous materials.
