Texturing (Na_0.5Bi_0.5)TiO₃-KNbO₃-SrTiO₃ Electrostrictive Ceramics by Templated Grain Growth Using (Na_0.5Bi_0.5)TiO₃ Platelets

Inorganics
Electrostriction is an intriguing behaviour of dielectric materials, characterized by stable electrostrain with minimal hysteresis. (Na0.5Bi0.5)TiO3-based ceramics show promising electrostrictive behaviour, particularly the 0.90(Na0.5Bi0.5)TiO3-0.08KNbO3-

Structure of nanoparticles embedded in micellar polycrystals

, 2012
We investigate by scattering techniques the structure of water-based soft composite materials comprising a crystal made of Pluronic block-copolymer micelles arranged in a face-centered cubic lattice and a small amount (at most 2% by volume) of silica ...

Oriented Graphene Nanoribbons Embedded in Hexagonal Boron Nitride Trenches

, 2017
Graphene nanoribbons (GNRs) are ultra-narrow strips of graphene that have the potential to be used in high-performance graphene-based semiconductor electronics. However, controlled growth of GNRs on dielectric substrates remains a challenge.
