Active materials can interchange types of energy. In a new cover article in the journal molecules, Geophysical Lab Staff Scientist Ronald Cohen and his colleague Haiwu Zhang report on predictions of a new class of polar metallocene crystals, which may be useful as active materials.
Reynold E. Silber of Yale University presented on "Mystery of transport properties of liquid transition metals and alloys along the melting boundaries - Implications for terrestrial cores.”
Piezoelectric materials are a class of smart materials that can convert electrical energy to mechanical energy and vice versa. Developing new piezoelectrics for novel electromechanical device applications has been a long-lasting interest, both scientifically and technologically. The negative response has been considered a rare and counterintuitive anomaly. The Geophysical Laboratory's Shi Liu and Ron Cohen showed that the negative response is not so rare after all.
The Geophysical Laboratory's Postdoctoral Fellow Shi Liu was awarded the 2017 APS Metropolis Award in late October. The purpose of the award is to recognize doctoral thesis research of outstanding quality and achievement in computational physics and to encourage effective written and oral presentation of research results.
The Geophysical Laboratory's weekly seminar series continues with our own Shi Liu. He will present, "Making sense of ferroelectric switching."
Washington, DC--Researchers at the Carnegie Institution have discovered a new efficient way to pump heat using crystals.
Washington, DC, 15 April 2010- Single-crystal relaxor ferroelectrics are useful and fascinating systems, but understanding the inner workings of these complex materials has been very challenging. They have spatial and temporal heterogeneities over a range of length and time scales.
