Two new technologies for removing heat from electronic devices could help future generations of laptops, PDAs, mobile phones, telecom switches and high-powered military equipment keep their cool in the face of growing power demands.

The patented technologies – synthetic jets that rely on trains of turbulent air puffs and a system that uses vibration to atomize cooling liquids such as water – were developed by Professor Ari Glezer and co-workers at the Georgia Institute of Technology’s School of Mechanical Engineering. The pair of technologies has been licensed to Atlanta-based company Innovative Fluidics, which will use them to meet a broad range of electronics cooling needs.
“There is a lot of concern in the electronics industry about thermal management,” said Raghav Mahalingam, a research engineer in Georgia Tech’s School of Mechanical Engineering. “New processors are consuming more power, circuit densities are getting higher and there is pressure to reduce the size of devices. Unless there is a breakthrough in low-power systems, conventional fan-driven cooling will no longer be enough.”

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
