Unveiling Exsolution‐Induced Giant Electronic and Magnetic Property Changes in Non‐Stoichiometric Titanate Perovskite Thin Films

Advanced Materials, EarlyView.
A giant insulator to metal transition and emergent superparamagnetism are revealed by nanoparticle exsolution in non‐stoichiometric titanate perovskite thin films. By combining transport, synchrotron spectroscopy, and first‐principles calculations, this work reveals how defect reconfiguration and lattice reconstruction fundamentally reshape electronic ...

Shape-Memory Solid Polymer Electrolytes

ECS Meeting Abstracts, 2021
Stimuli-responsive materials are smart materials capable to adjust their properties (e.g. shape and size) in response to an external or internal stimulus including temperature, light, magnetic field, mechanical stress, and pH. Shape memory polymers (SMPs) are attractive class of stimuli-responsive, programmable smart materials with shape-memory ...

Solid Polymer Electrolytes

2011
Solid polymer electrolytes which are solvent-free electrolytes based on polymers have potential for use in next-generation lithium ion batteries. These batteries, used in cell phones and laptop computers, currently contain a liquid electrolyte. Replacing the liquid electrolyte currently used has several advantages: it allows use of higher-energy ...
