Why Ferrofluid is Revolutionary

Ferrofluid is a type of fluid that contains suspended micro particles of iron, magnetite or cobalt in a solvent. The solvent is typically an organic fluid as a carrier, or water in some special cases where oil can be dangerous to use. Join our YouTube channel by clicking here: https://b

Ferroelectrics and Piezoelectrics

Why is it that titanates and zirconates can achieve such remarkably large dielectric constants? These perovskites have ions that can move substantially as the structure switches from cubic to tetragonal. The transition occurs at the Curie Temperature above which there is no net polarizatio

FERROFLUID underwater LIQUID MAGNET to NEODYMIUM Rare earth micro plastic

Ferrofluid is a magnetically active compound attracted to a rare earth or neodymium magnet that is dispersed throughout another substance or organic solvent resulting in micro particles and plastics to attach. It changes shapes and can demonstrate magnetic flux. flhttp://www.greenpowerscie

Attempting to make a ferrofluid

In this video, I'll be attempting to make ferrofluid from the ferric chloride and ferrous sulfate that I made in a previous video. At first, I thought that this project would be really straightforward, but it turned out to be much more difficult than I thought. I am going to be working mo

Thermoplastic vs Thermoset polymers

Some polymers can soften and melt upon heating allowing them to be easily recycled. Others simply catch fire and burn! The key difference is whether polymers are held together by van der Waals bonding or strong covalent bonds in 3 dimensions.

Why is the carbon solubility so different in ferrite vs austenite?

A phase diagram of Fe-C shows right away that austenite can withstand up to 2.14wt% C, whereas the solubility of C in ferrite is a measly 0.022wt% C. Why the big difference? Even more crazy, consider that ferrite is BCC which is only 68% densely packed while FCC is 74% packed. Why should t
