Move over, ceramics: New materials combine flexibility and ferroelectricity

By April Gocha / February 7, 2017

Scientists at Argonne National Laboratory in collaboration with researchers at Northwestern University have discovered that some organic ferroelectric materials are composed of crystal planes that atomically slide past one another, providing them with flexibility.

Marija Kosec mourned

By / January 14, 2013

Marija Kosec, from lecture, “Towards small size ferroelectrics” (click on image to watch). I have received several inquiries about the possible death of Marija Kosec. Unfortunately, Kosec indeed died in late December although its unclear if the exact date was Dec. 23 or 24, 2012. In an obituary I posted about Kosec on ACerS’ main website last…

Breakthrough in understanding piezoelectric mechanism in Pb-free ferroelectrics

By Eileen De Guire / September 11, 2012

Applying a poling field (Epol) creates a rhombohedral (R)/tetragonal (T) morphotropic phase boundary in a single phase grain of (Bi½Na½)TiO3-6%BaTiO3. Such direct in-situ transmission electron microscopy observations led to the establishment of an Epol vs x phase diagram for (1-x)(Bi½Na½)TiO3–xBaTiO3. Credit: Tan; Iowa State University. Lead zirconate titanate ceramics are the “gold standard” materials for…

Making ferroelectric nanorocks with an atomic force microscope hammer

By Eileen De Guire / February 7, 2012

Ferroelectric lead titanate nanodots were shattered using an atomic force microscope tip to make nanodots less than 10 nm diameter. Credit: Son and Jung, JACerS; Wiley. Jim O’Neil, a fellow graduate student a good while ago, liked to say, “Ceramic engineering is all about making big rocks into little rocks, and then making little rocks into…
