Super-cold microscope has super cool uses

While "go big" is the motto for many science initiatives, Penn State researchers are hoping a cutting-edge microscope will allow them to "go deep" to promote biomedical research and discoveries in materials science.  Full story

Ultrasensitive sensor using N-doped graphene

A highly sensitive chemical sensor based on Raman spectroscopy and using nitrogen-doped graphene as a substrate was developed by an international team of researchers working at Penn State. In this case, doping refers to introducing nitrogen atoms into the carbon structure of graphene. This technique can detect trace amounts of molecules in a solution at very low concentrations, some 10,000 times more diluted than can be seen by the naked eye.  Full story

Chad Hanna appointed Norman and Trygve Freed Early Career Professor in Physics

Chad Hanna, assistant professor of physics at Penn State, has been honored with the inaugural Norman and Trygve Freed Early Career Professorship in Physics. Hanna is a gravitational-wave astrophysicist. His research with the Laser Interferometric Gravitational-wave Observatory (LIGO) focuses on detecting gravitational waves emitted by binary neutron stars or black holes. Gravitational waves, first detected by LIGO in 2015, are "ripples" in spacetime predicted by Albert Einstein's theory of general relativity.  Full story
