View ArticleResearchers watch a next-gen memory bit switch in real time
For the first time, engineering researchers have been able to watch in real time the nanoscale process of a ferroelectric memory bit switching between the 0 and 1 states. Ferroelectric materials have...
View ArticleReliable nuclear device to heat, power Mars Science Lab
NASA’s Mars Science Laboratory mission, which is scheduled to launch this week, has the potential to be the most productive Mars surface mission in history. That’s due in part to its nuclear heat and...
View ArticleThe impending revolution of low-power quantum computers
By 2017, quantum physics will help reduce the energy consumption of our computers and cellular phones by up to a factor of 100. For research and industry, the power consumption of transistors is a key...
View ArticleNew ’3-D’ transistors promising future chips, lighter laptops
Researchers from Purdue and Harvard universities have created a new type of transistor made from a material that could replace silicon and have a 3-D structure instead of conventional flat computer...
View ArticleNovel device removes heavy metals from water
An unfortunate consequence of many industrial and manufacturing practices, from textile factories to metalworking operations, is the release of heavy metals in waterways. Those metals can remain for...
