What happens to the frequency (related to pitch) in an open-open tube when the length of the tube gets larger?
Is it higher? Lower? Same?

Dr. Balaz has the answer.

The first meeting of the new academic year will be held at 7 p.m. on Wednesday, September 24, in Room 2026, Ward Beecher Science Hall. Parking will be available in the M-1 (Wick Avenue) Parking Deck.

What is physics? Physics is the foundation of science. It is the scientific study of matter and energy and how they interact with each other. But because everything around us is made up of matter and energy, then physics really explains how things work, from the smallest particles to the structure of the universe.

If you have to ask "why study physics," then you don't get science. But if you want to truly understand the world around you, then welcome to our universe. You'll enjoy it here.

Welcome to the 2014-15 academic year!

Several members of the Department of Physics & Astronomy met with YSU President Jim Tressel during the "welcome back" event sponsored by the STEM College. Pictured are, from left: President Tressel, Tom Oder, Gregg Sturrus, Snow Balaz, Don Priour, Mike Crescimanno, Jim Andrews, Chuanhong Zhou, and Jill Mogg.

Plasma etching is on its way, thanks to NSF grant

Research related to the science and engineering of materials at Youngstown State University spans a broad spectrum and includes semiconductors, polymers, carbon nanotubes, ceramic-metallic composites and functional materials.

To meet the challenge in studying the diversity of these types of materials, researches from the STEM College have teamed up with industrial partners such as Fireline Inc. and Materials Research Laboratories, Inc. A major requirement in processing and studying these materials is the ability to remove unwanted layers of the material in order, for example, to fabricate a microelectronic device.

This “subtractive manufacturing” is best accomplished using high density plasma, which can etch materials as soft as polymers or as hard as ceramics. To etch, you need an etcher.

YSU will soon have its own etcher. A grant award in the amount of $307,422 was won by YSU by the National Science Foundation (NSF) to acquire a plasma etching equipment for conducting research on these materials.

The lead investigator of this grant was Dr. Tom Oder, Professor of Physics, assisted by co-investigators Dr. Pedro Cortes, Assistant Professor of Civil/Environmental and Chemical Engineering; Dr. Ruigang Wang, Assistant Professor of Chemistry; Dr. Virgil Solomon, Associate Professor of Department of Mechanical & Industrial Engineering; and Klaus-Markus Peters, General Manager Fireline TCON, Inc.

 Dr. Oder, who led this grant proposal, is the Director of the Wide Bandgap Semiconductor Research at YSU. He has successfully won previous major grant awards, including:

(a) NSF award for $224,500 (2010-2015),

(b) NSF award for $171,046 (2006-2010),

(c) Research Corporation for Science Advancement grant for $43,470 (2006-2008).

 Dr. Oder is also a co-principle investigator of several major grants in the STEM College.
