It’s nice in its way. It will play DVDs, it’ll write data on ‘em, it’ll even inscribe them with text and graphics if you care to utilize the Lightscribe function. But I can hardly think of a single situation in which something like this would be needed. Can you?

I mean, netbooks would croak after powering this thing for half an hour. Every regular-sized laptop worth its salt has a DVD drive already. The market for these must just be incredibly small.

Aussie Scientists Pack Massive Data Onto Single 5-D Discs

Aussies develop multi-terabyte optical storage…

Researchers at a University in Melbourne, Australia have come up with a “five dimensional” disc capable of storing 2,000 times more data than a conventional DVD.

That’s 10TB per DVD disc, in case you’re counting.

The research was conducted in Centre of Micro-Photonics at Swinburne University and was in the journal Nature.

Friday, May 22, 2009: For the first time, researchers from the University’s Centre for Micro-Photonics have demonstrated how nanotechnology can enable the creation of ‘five dimensional’ discs with huge storage capacities. Their findings point towards using nanoscopic particles to exponentially boost the amount of information stored on a single disc with a unique ‘five dimensional’ structure.

The discs are the same size as a conventional three dimensional existing DVDs.

This means that data – usually written in a typical three dimensional (x, y, z) fashion – acquired two more dimensions. So far this has already resulted in an optical disc sample capable of storing 1.6TB of data, but as development continues, researchers Min Gu, Peter Zijlstra and James Won expect storage capacity to reach a whopping 10TB.

 

We were able to show how nanostructured material can be incorporated onto a disc in order to increase data capacity, without increasing the physical size of the disc,” said Professor Min Gu, one of the researchers on the team.

The research, carried out by Peter Zijlstra, Dr James Chon and Professor Min Gu was published in the scientific journal Nature. The Nature article describes how the researchers were able to use nanoscopic particles to exponentially increase the amount of information contained on a single disc.

Discs currently have three spatial dimensions, but using nanoparticles the Swinburne researchers were able to introduce a spectral – or colour – dimension as well as a polarisation dimension.

 

“These extra dimensions are the key to creating ultra-high capacity discs,” Gu said.

 
To fabricate the ‘color dimension’, gold nanorods are interleaved into the disc’s surface. The information can then be recorded in a range of different color wavelengths on the same physical disc location. This is possible due to a unique characteristic of the nanoparticles, which react differently to light depending on their shape.

This is a major improvement on current DVDs that are recorded in a single colour wavelength using a laser.

None of these techniques are actually new, just the fact that they were all applied at the same time. This brings about at least one major problem that the technology has to contend with, that is, recording speed. Current prototypes record about as fast as a glyph-carver in ancient Egypt, the researchers have implied.

Another problem such high-capacity media are going to have to confront is tied up with several related terms like robustness, reliability and longevity. At least initially, most people will want to have such large capacity physical media offer some assurance that they won’t self-destruct within merely five or fifteen years as most presently available CD and DVD discs are all too prone to do.

But we guess the scientists are working on first things first, thinking about how to do this before working out how to make people believe it’s worth entrusting lots of valuable data to it.

The discs are likely to have immediate applications in a range of fields. They would be valuable for storing extremely large medical files such as MRIs and could also provide a boon in the financial, military and security arenas.

Students Create Portable Device To Detect Suicide Bombers

Washington, 27th June: A group of students have developed a portable device to detect the weapons of suicide bombers.

According to latest reports, improvised explosive devices (IEDs), the weapons of suicide bombers, are responsible for about half of soldier casualties in Iraq and Afghanistan. To get rid of these IEDs, A group of University of Michigan Engineering undergraduate students has developed a new way to detect IEDs that appears to be magnitudes cheaper than comparable approaches used.

Students invented a wireless network of portable hand-held metal detectors that could be hidden in trash cans, under tables, in flower pots. For Example, The detectors are designed to be part of a wireless sensor network that conveys to a base station where suspicious objects are located and who might be carrying them.

Compared with existing technology, the sensors are cheaper, lower-power and longer-range. Each of the sensors weighs about 2 pounds.

Nilton Renno, a professor in the U-M Department of Atmospheric, Oceanic and Space Sciences Expressed his sentiments as: The Invention of this man-portable device really exceed every technology that exist in Market today.

Ashwin Lalendran, an engineering student who worked on the project and graduated in May explained that:
“The core technology is based on a magnetometer, or metal detector. Our sensors are small, flexible to deploy, inexpensive and scalable. It’s extremely novel technology.”

 
The U-M students recently won an Air Force-sponsored competition with Ohio State University.The U.S. Air Force Research Laboratory at Wright Patterson, Air Force Base sponsored the project as well as the contest. “Such contests are regularly held across the country to provide rapid reaction and innovative solutions to the Department of Defense’s urgent needs,” says Capt. Nate Terning, AFRL rapid reaction projects director.

It is really an Excellent turnout in Technology. Tenning said, “Regardless of the competition results, often successful ideas from each student team can be combined into a product which is then realized for DoD use in the future.”

This project undertook in Renno’s Engineering 450 senior level design class. Renno said,
“They clearly have an excellent understanding of the problem. They also thought strategically and designed and optimized their solution. The combination of a movable command center with a wireless sensor network can be easily deployed in the field and adapted to different situations”

Bruce Block, an engineer in the Space Physics Research Laboratory who worked with the students express emotional feeling as,
“I am very proud of the team for applying a sound engineering approach and a lot of imagination to the solution of an extremely difficult real-world problem. They worked well together and never gave up when the going got rough

The students will continue to work on this project through the summer. Other students involved are:
Steve Boland, a senior atmospheric, oceanic and space sciences major,
Andry Supian, a mechanical engineering major who graduated in April,
Brian Hale, a senior aerospace engineering major,
Kevin Huang, a junior computer science major,
Michael Shin, a junior computer engineering major and
Vitaly Shatkovsky, a mechanical engineering major who graduated in April.

Other Space Physics Research Lab engineers who assisted are Steve Musko and Steve Rogacki
