The goal of this research project is to determine the viability of an interconnect and probing technology which could be used to test and burn-in unpackaged semiconductors at system level speed, and at operating frequency, with voltage and with temperature margins verified. The focus of the research will be to address directly the most costly limitation to widespread MCM use; the problem of readil ...

We propose to demonstrate the feasibility of fabricating a phototransistor using the A1xGa1-xN material system. The proposed phototransitor is based on a GaN-A1xGa1-xN heterojunction which exhibits a 2-D electron gas conduction when a bias is applied on the source-drain terminals. The device is maintained in a nominally OFF state by applying a reverse bias voltage on the gate terminal. With optica ...

ONCE THOUGHT TO BE A PROBLEM ASSOCIATED ONLY WITH ELITE ATHLETES, ANABOLIC STEROID ABUSE IS NOW UNDERSTOOD TO PERMEATE ALL LEVELS OF ATHLETICS, FROM HIGH SCHOOL TO PROFESSIONAL, AND IS GROWING IN POPULARITY AMONG NON-ATHLETES AS WELL. VIEWED IN CONTEXT OF THE SUBSTANTIAL HEALTH RISKS ASSOCIATED WITH CHRONIC STEROID INGESTION, AND IN PARTICULAR, IN ADDITIONAL HEALTH RISKS FACED BY ADOLESCENT ABUSER ...

We will develop reagents and methods for coating fabrics for use in medical applications; these fabrics will include surgical gowns and drapes that will protect both health care workers and patients from transmission of pathogens, such as HIV and hepatitis viruses. The methods will use photochemistry for covalently coating nonwoven fabrics with both hydrophilic photopolymers and hydrophobic photor ...

A project is proposed to develop reagents and methods for coating latex rubber devices to prevent leaching of allergenic proteins. Allergies to latex rubber proteins has become recognized as a serious problem in recent years. These allergic problems are partly due to increased exposure by medical personnel and patients resulting from increased use of latex gloves for protection from exposure to th ...

All synthetic materials which contact blood are thrombogenic and activate processes such as fibrin coagulation, platelet adhesion, and complement activation. Numerous investigations have been conducted to develop nonthrombogenic materials because of these observations. These include chemical modifications of the natural surface by the addition of hydrophilic moieties or immobilization of biologica ...
