Nanotechnology paves way for super iPodsIssued: Tue, 15 Apr 2008 15:42:00 BST
A breakthrough by scientists from the University of Glasgow could see the storage capacity of an iPod increase 150,000 times. Nanotechnology researchers have developed a molecule-sized switch which means that data storage can be dramatically increased without the need to increase the size of devices. Professor Lee Cronin and Dr Malcolm Kadodwala’s work would see 500,000 gigabytes squeezed onto one square inch. The current limit for the space is around 3.3 gigabytes. The researchers believe that their development could see the number of transistors per chip rising from today’s limit of 200million to well over one billion. Professor Lee Cronin said: “What we have done is find a way to potentially increase the data storage capabilities in a radical way. “We have been able to assemble a functional nanocluster that incorporates two electron donating groups, and position them precisely 0.32 nm apart so that they can form a totally new type of molecular switching device. “This is unprecedented and provides a route to produce new a molecule-based switch that can be easily manipulated using an electric field. “By taking these nano-scale clusters, just a nanometer in size, and placing them onto a gold or carbon, we can control the switching ability. Not only is this a new type of switchable molecule, but by grafting the molecule on to metal (gold) or carbon means that we can potentially bridge the gap between traditional semiconductor devices and components for nanoscale plastic electronics. “The key advantage of the molecule sized switch is information / transistor density in traditional semi-conductors. Molecule sized switches would lead to increasing data storage to say 4 Petabits per square inch. “This breakthrough shows conceptually that this is possible (showing the bulk effect) but we are yet to solve the fabrication and addressing problems. “The fact these switches work on carbon means that they could be embedded in plastic chips so silicon is not needed and the system becomes much more flexible both physically and technologically. “Since these switches are little balls of metal oxide they are made of similar stuff to normal semi-conductors but are much easier to manipulate as discrete molecular units.
The breakthrough was reported in this month’s edition of the prestigious journal, Nature Nanotechnology.

Wi- fi technology

Wi-Fi (IPA: /ˈwaɪfaɪ/) is the common name for a popular wireless technology used in home networks, mobile phones, video games and more. Wi-Fi is supported by nearly every modern personal computer operating system and most advanced game consoles.
Advatages:

Wi-Fi allows LAN's(Local Area Networks) to be deployed without cabling for client devices, typically reducing the costs of network deployment and expansion. Spaces where cables cannot be run, such as outdoor areas and historical buildings, can host wireless LANs.
As of 2007 wireless network adapters are built into most modern laptops. The price of chipsets for Wi-Fi continues to drop, making it an economical networking option included in even more devices. Wi-Fi has become widespread in corporate infrastructures.
Different competitive brands of access points and client network interfaces are inter-operable at a basic level of service. Products designated as "Wi-Fi Certified" by the Wi-Fi Alliance are backwards inter-operable. Wi-Fi is a global set of standards. Unlike mobile telephones, any standard Wi-Fi device will work anywhere in the world.

Disadvantages:
Spectrum assignments and operational limitations are not consistent worldwide. Most of Europe allows for an additional 2 channels beyond those permitted in the U.S. for the 2.4 GHz band. (1–13 vs. 1–11); Japan has one more on top of that (1–14). Europe, as of 2007, was essentially homogeneous in this respect. A very confusing aspect is the fact that a Wi-Fi signal actually occupies five channels in the 2.4 GHz band resulting in only three non-overlapped channels in the U.S.: 1, 6, 11, and three or four in Europe: 1, 5, 9, 13 can be used if all the equipment on a specific area can be granted not to use 802.11b at all, even as fallback or beacon. Equivalent isotropically radiated power (EIRP) in the EU is limited to 20 dBm (0.1 W).
