Transparent, flexible memory chips could replace flash

By - April 2, 2012 2 Pictures
According to Dr. James M. Tour, a synthetic organic chemist at Houston’s Rice University, flash memory devices can only be built smaller for another six to seven years – at that point, they will reach a technological barrier. Already, however, Tour and his colleagues have developed a new type of memory chip, which they believe could replace flash in thumb drives, smartphones and computers. Not only does their chip allow more data to be stored in a given space, but it can also be folded like paper, withstand temperatures of up to 1,000ºF (538ºC), and is transparent – this means that devices’ screens could also serve as their memory.

Doctor creates his own Tricorder

By - April 2, 2012 24 Pictures
If Star Trek has taught us anything, it's the importance of gathering as much information about the alien planet you've just been beamed onto as quickly as possible. To that end, the Science Officer on the away team would perform a quick scan of the surroundings with a handheld, multifunctional sensing device called a Tricorder. Fortunately, we now live in an age where the science fiction of yesteryear is increasingly becoming the science fact of today, and the once futuristic Tricorder is no exception. For his Tricorder Project, Canada's Dr Peter Jansen has designed and built some pocket-friendly devices housing a number of sensors which reveal the secrets of the unseen world around us. Read More

DVD writer spins out graphene electrodes for new class of supercapacitor

By - March 26, 2012 2 Pictures
The wonders of graphene seem to know no bounds. Not only is it one of the strongest materials known, is both highly conductive and piezoelectric, it can generate electricity from flowing water and now it is being used to make better supercapacitors. Using a DVD writer, a team of UCLA researchers has invented a new process for making high quality graphene electrodes and used these electrodes to make a new species of supercapacitor. Though the work is in the early stages of development, it could lay a foundation for supercapacitor-based energy storage systems suitable for flexible portable electronic devices. Read More

Piezolelectric graphene could have wide-reaching applications

By - March 22, 2012
Scientists have succeeded in endowing graphene with yet another useful property. Already, it is the thinnest, strongest and stiffest material ever measured, while also proving to be an excellent conductor of heat and electricity. These qualities have allowed it to find use in everything from transistors to supercapacitors to anti-corrosion coatings. Now, two materials engineers from Stanford University have used computer models to show how it could also be turned into a piezoelectric material – this means that it could generate electricity when mechanically stressed, or change shape when subjected to an electric current.

Sony develops power outlet that can recognize devices and users

By - March 21, 2012 4 Pictures
Sony has developed a power outlet that can identify devices plugged into it, as well as individuals using the plug. The company says such technology could allow the electricity usage of individual devices to be monitored so non-essential devices could be switched off remotely in the event of limited electricity supply, or for the billing of customers charging their electric vehicles or mobile devices in public places.

IBM unveils one trillion bit-per-second optical chip

By - March 12, 2012 2 Pictures
Last Thursday at the Optical Fiber Communication Conference in Los Angeles, a team from IBM presented research on their wonderfully-named “Holey Optochip.” The prototype chipset is the first parallel optical transceiver that is able to transfer one trillion bits (or one terabit) of information per second. To put that in perspective, IBM states that 500 high-def movies could be downloaded in one second at that speed, while the entire U.S. Library of Congress web archive could be downloaded in an hour. Stated another way, the Optochip is eight times faster than any other parallel optical components currently available, with a speed that’s equivalent to the bandwidth consumed by 100,000 users, if they were using regular 10 Mb/s high-speed internet.

New supermarket scanner recognizes objects by appearance, not barcodes

By - March 8, 2012 6 Pictures
At some point, we’ve probably all had a supermarket cashier ask us to identify the mysterious fresh produce that we’re attempting to buy. Once we’ve told them what it is, they have then had to manually type in its code – they have to enter it themselves, of course, given that fruits and vegetables don’t have barcodes. Thanks to Toshiba Tec, however, those days may be coming to an end. The company’s new Object Recognition Scanner is able to instantly identify grocery items of all types based on their appearance alone. Read More

Biodegradable transistors created from proteins found in the human body

By - March 7, 2012
In a bid to develop a transistor that didn’t need to be created in a “top down” approach” as is the case with silicon-based transistors, researchers at Tel Aviv University (TAU) turned to blood, milk and mucus proteins. The result is protein-based transistors the researchers say could form the basis of a new generation of electronic devices that are both flexible and biodegradable. Read More
