World's first fully digital radio transmitter built purely from microprocessor technology

By - March 5, 2015
For the first time in history, a prototype radio has been created that is claimed to be completely digital, generating high-frequency radio waves purely through the use of integrated circuits and a set of patented algorithms without using conventional analog radio circuits in any way whatsoever. This breakthrough technology promises to vastly improve the wireless communications capabilities of everything from 5G mobile technology to the multitude devices aimed at supporting the Internet of Things.

Tiny Uamp turns your music-playing smartphone into a portable hi-fi

By - March 4, 2015 7 Pictures
The speakers on many smartphones can be painfully lacking in detail and bottom end, and really start to distort when the volume is pushed to levels guaranteed to annoy fellow commuters. Listening to music with the help of the built-in headphone jack will almost certainly offer an improved sonic experience, but high quality? Probably not. External headphone amps can help to increase the quality of mobile music devices, but (with some notable exceptions) these can add significant bulk to your pocket. A tiny new headphone amp named Uamp is making a bid for production on Kickstarter and, though small in size, its makers reckon that portable music lovers are in for a clearer, louder and richer listening experience.

New electrolyte promises to rid lithium batteries of short-circuiting dendrites

By - March 2, 2015 2 Pictures
Dendrites – thin conductive filaments that form inside lithium batteries – reduce the life of these cells and are often responsible for them catching fire. Scientists working at the Pacific Northwest National Laboratory (PNNL) of the US Department of Energy claim to have produced a new electrolyte for lithium batteries that not only completely eliminates dendrites, but also promises to increase battery efficiency and vastly improve current carrying capacity.

Going small with silicon potentially has big implications for lithium-ion battery capacity

By - February 25, 2015 3 Pictures
Researchers at the University of California, Riverside (UCR) have developed a silicon anode for lithium-ion batteries that outperforms current materials and gets around previous issues that would cause the battery to be inefficient and quickly degrade (or even fail catastrophically) with use. As the researchers focus on scaling up production, the advance could pave the way for higher-performance electric vehicles, electronics and all-around portable power. Read More

GE RFID tech turns stickers into explosives detectors

By - February 24, 2015 2 Pictures
A global economy brings many benefits, but it also makes international terrorism extremely difficult to combat. With more goods passing through the world's shipping terminals and airports than ever before, hunting explosives with large, static detectors or teams of inspectors armed with detecting devices and reagents is a bottleneck that increases the chances of evasion. To help US counterterrorism efforts, GE has developed RFID stickers that act as wireless, battery-free explosives detectors that can be placed almost anywhere. Read More
