Dr. Gomez Public Lecture at UPLB |
|
Dr. Romel D. Gomez, Professor of Electrical Engineering in the University of Maryland, College Park, and our Balik Scientist last year, will be here on Thursday and Friday, July 16-17, 2009, for a short research visit. On Friday at 11:00 a.m. at PSLH-B, he will deliver a public lecture titled "Visualizing and manipulating objects at the nanometer length scale". The visit is hosted by the IMSP-Physics Division. You are all invited, and please help us send this invitation to others.

Visualizing and manipulating objects at the nanometer length scale
In the closing decades of this millennium our civilization has seen the rise in scientific and popular interest in tiny entities. We have begun to accept as common place, previously unexpected and seemingly impossible effects that occur at very short length scales. We have used new theories, rooted in quantum mechanics, to build faster and better computing tools, store massive amounts of data, diagnose and treat human afflictions, generate energy, and provide new insights into the nature of matter. We have even introduced the word "nanotechnology" in the English vernacular to indicate novel artifacts with sizes that approach a billionth of a meter.
In this talk, I will focus on one aspect of nanotechnology, the scanning probe microscopy, which is a tool that spurred advances in this area. This technique and its numerous variations have revealed the intricate details of objects far beyond the resolution of visible light and have made the world of atoms much more accessible to tabletop experimentation. I will review the key principles and will provide examples of applications in solid state physics, biology, magnetism as well as fabrication processes at the nanometer length scale. |
