CAMP's Annual Technical Meeting 2003

THIN FILMS AND COATINGS

Deposition of Diamond Films, Aluminum Alloy Solidification, and Contact Angle Measurements

Professor Liya L. Regel has continued research on the deposition of diamond films on a variety of substrates, including those of interest to Kodak, Corning and other companies. Her group is utilizing a new, simpler, less expensive method than has been used previously. Deposition has been achieved on substrates that had previously appeared impossible. Several invention disclosures have been submitted.

CAMP Professor Regel and Clarkson Distinguished Professor William Wilcox are also working with scientists from the Ioffe Physical Technical Institute in St. Petersburg, Russia to determine the influence of levitation and centrifugation on the microstructure and properties of aluminum alloys. Thus far, a variety of hypo- and hyper-eutectic alloys of Al-Ge and Al-Si-Ge were melted and solidified during levitation and centrifugation.

In addition, an apparatus was developed for determining the influence of gas composition on surface tension and contact angle of high-melting materials using the sessile drop technique. Several molten salts were measured for Osram Sylvania. For a NASA grant, it was determined that oxygen and hydrogen both lower the surface tension of molten Ga-doped InSb. Oxygen also lowered its contact angle on fused silica (quartz).

They are working under the first grant at Clarkson from the U.S. Civilian Research and Development Foundation.

PARTICLE TRANSPORT, DEPOSITION AND REMOVAL

Inhalation Drug Delivery and Lung Deposition

Clarkson Distinguished Professor Goodarz Ahmadi (the Robert R. Hill '48 Professor) and Professor Philip Hopke (the Bayard D. Clarkson Distinguished Professor), in collaboration with Dr. Yung Sung Cheng of Lovelace Respiratory Research Institute,are studying fiber deposition in the human lung. Earlier Professor Ahmadi and Dr. Han and Dr. Greenspan of Sura Pharmaceuticals studied powder dispersion in inhalation drug delivery systems.
