11 megapixel micro-mirror array
(Preview)
At today's IEEE International Electron Devices Meeting, IMEC presents a monolithically integrated 11 megapixel micro-mirror array for high-end industrial applications, a world's first both in terms of pixel density and reliability. Each mirror in the array is 8µm x 8µm and can be individually...

Basic fluid mechanics
(Preview)
MIT researchers have found an elegant solution to a sticky scientific problem in basic fluid mechanics: Why water doesn't soak into soil at an even rate, but instead forms what looks like fingers of fluid flowing downward. Scientists call these rivulets "gravity fingers," and the expl...

Magnetic shield
(Preview)
Magnetic shield for spacefarers Future astronauts could benefit from a magnetic "umbrella" that deflects harmful space radiation around their crew capsule, scientists say. The super-fast charged particles that stream away from the Sun pose a significant threat to any long-durati...

Mathematics
(Preview)
The last two instalments of Engineering on Purpose have focused on fundamental attributes of linear systems and the mathematics that describe them. The approach to the subject centred on simple linear time-invariant circuits (LTICs) with the implicit suggestion that the same techniques could...

Buckypaper
(Preview)
It's called "buckypaper" and looks a lot like ordinary carbon paper, but don't be fooled by the cute name or flimsy appearance. It could revolutionise the way everything from airplanes to TVs are made. Buckypaper is 10 times lighter but potentially 500 times stronger than steel when she...
