Investigate at Nanoscale.

In 2004, the Nanophotonics Fabrication Laboratory was built with grants from the University of Dayton and the Ohio Third Frontier project. Nanoscale components research for telecommunications and infrared applications for commercial, military, safety and security purposes is conducted.

NSF Nanotechnology Grant

Linking the University of Dayton and Sinclair Community College.

We have a joint National Science Foundation (NSF) grant with Sinclair Community College to introduce nanotechnology to undergraduates and two-year colleges. Through this, we have introduced two undergraduate courses at UD (EGR-311 and EGR-411) and two courses at Sinclair.

Live Video System

We built a remote video system to link any laboratory on campus to the classroom. The system, on a cleanroom compatible mobile cart, is portable from one laboratory to another with the intent to leverage existing research laboratories, which may be located in different buildings. The laboratory codec communicates with the classroom codec through the Internet or campus intranet. The cart also has a large LCD monitor to allow the operator in the laboratory to see and interact with the classroom. Two high-definition cameras can be moved and zoomed by the laboratory operator and also by the instructor at the classroom end. The video and audio are two-way, with multiple wireless microphones at the student desks, allowing the students to interact with the laboratory instructor and the laboratory instructor to see the students in real time.
