Helion sez, "Good news for goth clothing - darkest ever material created from a forest of nearly totally light-absorbing carbon nanotubes.
Dark forest indeed."
A team led by Dr Pulickel Ajayan, who is presently at Rice University in Houston, Texas, built an array of vertically aligned, low-density carbon nanotubes. Dr Shawn Lin measured the optical properties.
The roughness of the material's surface was tuned to minimise its optical reflectance.
Experiments showed that this "forest" of carbon nanotubes was very good at absorbing light, and very poor at reflecting it.

High-def cameras are available to anyone and for much less than they were just a decade ago. Even the phones in our pockets can be used to shoot and edit short films. It’s never been easier to be a filmmaker, providing you have the technique. Enter the Film & Cinematography Mastery Bundle, an online boot […]
Breaking into the indie video game market may be easier than you think. It all starts with an idea, and then it’s a matter of finding the right development platform to bring it to life. No matter what that platform is, it’s a good bet that it’s covered in the 2019 Game Dev & Design […]
Learning a new language like Spanish doesn’t have to be hard. Either you can buy a ticket to a Spanish-speaking country, immerse yourself in the culture and pick it up intuitively – or you can do it from the comfort of the chair you’re in right now by logging on to Rocket Spanish. There are […]
