nano scale

A ferrofluid is a fluid that becomes strongly magnetized in the presence of a magnetic field. Essentially, they’re nano-scale particles of magnetic iron suspended in an organic solvent. Put them near a magnet and things get really awesome really fast. (Source: Business Insider)


Scientists record heat moving through materials at speed of sound

Providing unprecedented insight into roles played by individual atomic and nano-scale features, researchers have recorded the first-ever videos showing how heat moves through materials at the nano-scale traveling at the speed of sound.

The groundbreaking videos were made using a state-of-the-art ultrafast electron microscope called FEI Tecnai Femto, which is capable of examining the dynamics of materials at the atomic and molecular scale over time spans measured in femtoseconds (one millionth of a billionth of a second).
