Penn State researchers have observed and reported a new material that could make energy storage safer.
that demonstrate a spontaneous electric polarization when an external electric charge is applied. This causes a spontaneous electric polarization when positive and negative charges in the materials head to different poles. These materials also have piezoelectric properties, which means the material generates an electrical charge under an applied mechanical force.
Nasim Alem, Penn State associate professor of materials science and engineering and the study’s corresponding author, said, “We would love to design a piezoelectric material that doesn’t have the disadvantages of the current materials. And right now, lead in all these materials is a big disadvantage because the lead is hazardous. We hope that our study can result in a suitable candidate for a better piezoelectric system.
There is also a unique characteristic of CMO’s microstructure that is something of a mystery to researchers. Alem noted, “We monitored the material, what’s going on during the phase transition, and were able to probe atom by atom at what type of bonding we have, what type of structural distortions we have in the material, and how that may change as a function of temperature. And this is very much explaining some of the observations that people have had with this material. For example, when they get the thermal expansion coefficient, no one has really known where this comes from.
