Toothpick Fab Tools NASA's Goddard Space Flight Center in Greenbelt, Md. has developed a specialized atomic layer deposition (ALD) system and a "virtual toothpick" to enable ultra-thin films on chips and systems. NASA has built an ALD reactor chamber, which measures three inches in diameter and two feet in length. The system can deposit films inside pores and cavities, giving ALD the abilit... » read more

Diamond chips The optical transistor, which transports photons, holds great promise. Photons are not only faster than electrons, but they have less crosstalk. But optical transistors are also expensive and difficult to produce. In a possible breakthrough, the ICFO-Institute of Photonic Sciences has demonstrated a “nano-size” diamond that can act as an efficient optical switch. Researche... » read more

Space Tubes In 2011, NASA produced a material that absorbs on average more than 99% of the ultraviolet, visible, infrared, and far-infrared light that hits it. NASA’s so-called “super-black” material is based on a thin layer of multi-walled carbon nanotubes. Tiny gaps between the nanotubes collect and trap light. The carbon absorbs the photons, preventing them from reflecting off surf... » read more
