Why is it so hard to get around a nanoscopic world?


For a machine the size of a virus, the rules of locomotion are weird and surprising. Water behaves like jittery molasses. Solids are sticky. Just hovering near certain surfaces can repel a tiny vehicle like a same-pole magnet would.

The nanoworld is also vast compared to the macroscopic one, and suitable materials to build motors for nanobots are limited at best.

“Trying to move a nano device at the speed and direction you want is like fighting a hurricane,” said nanotechnologist Daniela Wilson of Radboud University in the Netherlands. “It’s a real challenge to have complete control over the movement.”

As consumers, no one ever complains that their wireless connectivity is “too fast”. Global wireless carriers and network providers continue to push the limits of 4G LTE, but a next-generation wireless standard – 5G New Radio (5G NR) – is on the horizo...

Torrents of packets will cascade into the data center: endless streams of data from the Internet of Things (IoT), massive flows of cellular network traffic into virtualized network functions, bursts of input to Web applications. And hidden in the cascades, far darker bits try...

Our existing customers ask us some pretty big questions: “How can this technology implement a step-change in my specific process? How can Speedcore IP be integrated in my SoC? How can you increase the performance of my ASIC?” We revel in answering such questions. Ho...
