Ionic Solids
In this video Paul Andersen explains how ionic solids form a lattice between cations and anions. According the Coulomb's Law the lattice energy increases as the ions carry a larger charge and are smaller. Some of the properties of ionic...

TED-ED: What is metallic glass? - Ashwini Bharathula
Steel and plastic are essential to much of our infrastructure and technology. Steel is strong and hard, but difficult to shape intricately. Plastic can take on just about any form, but it's weak and soft. Wouldn't it be nice if there...

TED-Ed: How to squeeze electricity out of crystals - Ashwini Bharathula
It might sound like science fiction, but if you press on a crystal of sugar, it will actually generate its own electricity. This simple crystal can act like a tiny power source because sugar happens to be piezoelectric. Ashwini...
