Science colloquia discusses physical properties of transition metals

The next Penn State Berks Division of Science Colloquium will feature Dr. Thomas Winter, Professor of Physics at Penn State Wilkes-Barre, who will give a presentation titled “Physical Properties of the Transition Metals" on Friday, Oct. 19, 2012, at 1 p.m. in room 125, Luerssen Building. This presentation is free and open to the public and light refreshments will be served.

According to Winter’s abstract, “The 30 transition metals are characterized by a d sub-shell being filled after the outer s sub-shell. These metals occupy the middle of three rows of the periodic table, and range from the common, such as iron, to the extremely rare, such as osmium. I have obtained samples of all the solid ones except (radioactive) technetium, and will focus on a few of their basic physical properties, including density and specific heat. For the common metals, such properties are typically measured by students in an introductory lab, but with little or no attempt to relate a property for one metal to that for another. Further, for a given metal, one property can often be related to another property. And the limits of accuracy can be pushed and common reference standards (the CRC Handbook and Kittel) can possibly be improved upon. Finally, I will touch on recent controversies on some of these physical properties.”

The Science Division colloquia are of broad and general interest, accessible to a general audience. All students, faculty, and interested members of the Penn State Berks and surrounding community are encouraged to attend.
