Materials scientists can learn a lot about a sample material by shooting lasers at it. With nonlinear optical microscopy — a specialized imaging technique that looks for a change in the color of intense laser light — researchers can collect data on how the light interacts with the sample and, through time-consuming and sometimes expensive analyses, characterize the material’s structure and other properties. Now, researchers at Penn State have developed a computational framework that can interpret the nonlinear optical microscopy images to characterize the material in microscopic detail.

Clive Randall, Evan Pugh University Professor of Materials Science and Engineering, has been elected as a fellow of the European Academy of Sciences. The academy is an international scientific organization composed of the world’s leading scientists, scholars and engineers, dedicated to promoting excellence in science and technology.

Building on a legacy of excellence in glass science and engineering, the new Center for Glass Research (CGR) was recently launched at Penn State. It brings together the expertise of researchers from Penn State, Alfred University, and the Missouri University of Science and Technology (Missouri S&T) in a strategic collaborative initiative.

UNIVERSITY PARK, Pa. — A new twist on a classic material could advance quantum computing and make modern data centers more energy efficient, according to a team led by researchers at Penn State.   

Barium titanate, first discovered in 1941, is known for its powerful electro-optic properties in bulk, or three-dimensional, crystals. Electro-optic materials like barium titanate act as bridges between electricity and light, converting signals carried by electrons into signals carried by photons, or particles of light.

Penn State commemorates 70 years since faculty member Erwin Müller became the first person to ‘see’ atoms

By Katie Yan

Seventy years ago, in Osmond Laboratory on Penn State’s University Park campus, Erwin W. Müller, Evan Pugh Research Professor of Physics, became the first person to “see” an atom. In doing so, Müller cemented his legacy, not only at Penn State, but also as a pioneer in the world of physics and beyond.

When patients undergo reconstructive surgery for devastating injuries, one of the biggest obstacles surgeons face is restoring blood supply to the repaired tissue. Without a functioning vascular system, new grafts cannot survive. With a new $3 million grant from the National Institutes of Health, researchers at Penn State are taking on this challenge by combining advanced 3D bioprinting with a novel surgical method, known as micropuncture.
