What’s transparent, stretchable, nearly weightless, flexible enough to be sown onto a shirt and plugs into your iPod? Maybe, soon, this may describe one of the best and most durable audio speakers you’ll ever own. A group of Chinese researchers have discovered that, by zapping an audio-frequency current through a carbon nanotube thin film, it …

Perhaps we shouldn’t read too much into the microscopic faces of Barack Obama (shown above) that University of Michigan professor John Hart has created using carbon nanotubes, optical and scanning electron microscope. One has to wonder, however, if Hart’s creations are meant to convey a symbolic message – like the potential that both nanotechnology and the …

[flash /ceramictechtoday/wp-content/video/Aerogel.flv mode=1 f={image=/ceramictechtoday/wp-content/video/Aerogel.jpg}] This week’s video is actually a three-in-one aerogel feature. Aerogel is wispy, translucent, highly insulating material often described as “solid smoke.” It’s worth noting that aerogel is not a new material and may date back to the 1930s. Many new applications and lower-cost production processes, however, are opening up. The first …
