Q-Dots

Quantam dots or in short Q-dots is an upcoming area of nanotechnology for digonostic and sensoring application in biomedical field.

Q-dots are tiny semiconduction of 1-10nm in size and work exteremely fast for flouroscence detetction and imaging in cell and molecular biology.

Compared to organic dyes they offer possibilities like multiplexed imaging and long-term investigations, e.g. for cell uptake studies and in-vivo imaging, due to their tunable emission wavelength and an increased photostability up to several months.
 
well sorry for not sharing knowlege here but i am reading on regular basis abt wireless and nano tech and similar links too...
sir as sumit said no probs being a small grp too... its individual interest and cant enforce anyone to come and participate... but its so kind of u of starting such a worthy thread... keep pouring sir... ue posts r not going waste... thanks
 
guys if this thread here in general was meant to dissent the technology to the not-so-tech savvy people, it had to be in layman's lingo...

in a layman's diction, GSM phones have SIM (changeable) cards and are hi-end sets. on the contrary, CDMA phones don't have a SIM and the card is linked to the phone which can't be exchanged with any other handset.

Let's Google!!

10 tips for optimized Google search phrases


1. Explicit phrase: To search on the net for an exact word combination in Google, enclose your search within double quotes.
Example: "google tips"

2. Exclude words: To exclude words from the found webpages of Google, simply use the "-" symbol in front of the word you want to exclude.
Example: "google tips" -advertising

3. Site specific search: If you're looking on an specific phrase on a specific site (if it doesn't have a search function itself), use the "site:www.thesearchedsite.com" modifier.
Example: "google tips" site:www.marcofolio.net

4. URL specific search: In addition to my previous tip: What if you don't know the full site name? Of what if it has subdomains you want to search through? Use the "inurl:" modifier to search for things what is within the URL.
Example: "google tips" inurl:www.marcofolio.net

5. Similar terms: Use the "~" symbol in front of a search word to return similar terms or synonyms of that word.
Example: "google tips" ~useful

6. Use a wildcard: For example, if you're looking for some lyrics but you couldn't remember the full song, use the wildcard symbol "*" between the words. In the example Google will return the lyrics from The Beatles - Can't buy me love.
Example: can't * me love lyrics.

7. Specific document filetypes: Looking for a file which has your search phrase in it? Try the "filetype:" modifier. This example will return all DOC (Microsoft Word) files.
Example: "google tips" filetype:doc

8. This OR that: By default, when you do a search, Google will include all the terms specified in the search. If you are looking for any one of one or more terms to match, then you can use the OR operator. (Note: The OR has to be capitalized or the "||" combination can be used).
Example: "google tips" || "yahoo search"

9. Numeric Ranges: This little-known feature searches for a range of numbers. Looking for the best movies from 2002 until now? Try the example (note the two periods between the two number).
Example: best movies 2002..2007

10. Cached pages: Looking for a version of a page the Google stores on its own servers? This can help with outdated or update pages. Use the "cached:" modifier.
Example: cached: marcofolio.net

Happy google-ing :-)!!

Thanks,
Sumit

Blu-ray...all the way :-)!

Source: http://en.wikipedia.org/wiki/Blu-ray_Disc

Blu-ray Disc
Blu-ray Disc (also known as Blu-ray or BD) is an optical disc storage media format. Its main uses are high-definition video and data storage. The disc has the same dimensions as a standard DVD or CD. The name Blu-ray Disc is derived from the blue-violet laser used to read and write this type of disc. A Dual Layer Blu-ray Disc can store 50 GB, almost six times the capacity of a dual-layer DVD.

As of February 19, 2008, more than 450 Blu-ray Disc titles have been released in the United States, and more than 250 in Japan. Blu-ray was locked in a format war against HD DVD until the format emerged as the winner on February 19, 2008 when Toshiba — the main driving force behind HD DVD — announced it would no longer develop, manufacture and market HD DVD players and recorders.

Like its rival format HD DVD, Blu-ray uses a "blue" (technically violet) laser operating at a wavelength of 405 nm to read and write data. Conventional DVDs and CDs use red and near infrared lasers at 650 nm and 780 nm respectively.

The blue-violet laser's shorter wavelength makes it possible to store more information on a 12 cm CD/DVD sized disc. The minimum "spot size" on which a laser can be focused is limited by diffraction, and depends on the wavelength of the light and the numerical aperture of the lens used to focus it. By decreasing the wavelength, increasing the numerical aperture from 0.60 to 0.85 and making the cover layer thinner to avoid unwanted optical effects, the laser beam can be focused to a smaller spot. This allows more information to be stored in the same area. In addition to the optical improvements, Blu-ray Discs feature improvements in data encoding that further increase the capacity. (See Compact disc for information on optical discs' physical structure.)

Sir
You are absolutely right. Science gives you reasoning. As far as Nanotechnology is concerned, its biggest application is in military hardware. For example, F-22A Raptor, B2 Stealth bomber and much more. Other fields using nanotechnology is Medical field. Miniaturization of tools needed to perform the most complex surgeries are possible by nanotechnology. It is the most promising field of future, combine nanotechnology with Biotech and you have a recipie of success.
Just my thought.

first of all lemme thanx uncle Brigadier Lakshman Singh for starting such a gud thread. i think myself a techie... n uncle told us bout some stuff unknown to me. i feel like in infancy stage in technology... so here is my small contri ... i ve already posted in tech talk section... so its now just a copy - paste.

Smart homes may become a reality soon (BSNL to start 500 MBPS)

Remember all those stories about remote-controlled gadgets at home. These have remained dreams for Indians. Not any more. Bharat Sanchar Nigam Ltd (BSNL) is all set to install and test a killer application that will offer broadband speeds of at least 500 mbps (250 time the current speed) to homes through fibre optics network in Kolkata. Such speeds will be the basic enabler for these dream technologies.

Currently, BSNL offers a broadband speed of 2 mbps that can be stretched to 16 mbps allowing limited internet-based value added services like gaming and steaming video. Mbps is the speed at which a certain volume of data travels every second. Faster speeds help run more intelligent applications.

BSNL is currently working on two technologies. One that will offer speeds of 100 mbps and the other that will allow at least 500 mbps. The 100 mbps project will allow users to make his/her entire house a local area network on which all gadgets like TV, refrigerator, washing machine, micro-wave, gizzard, water filter or the lock at the main door and the gate will be connected. All these can be controlled remotely through a wireless gadget like the cell phone or any other handheld devices.

“These kind of applications require at least 100mbps speeds, termed FTTP (fibre to the premises). Once this speed is achieved a few additional instruments at the users end will enable wireless gadgets to control almost all electronic and electrical devises from remote locations. We are in advanced stage of rolling out this service. It has already been tested and will initially be offered to clusters of housing or large residential campuses. We will roll it out over the next two years,” BSNL’s chief general manager (Calcutta telephones) S K Chakravarti said.

He was talking to reporters on the sidelines of a seminar on telecom organised by Merchant Chamber of Commerce. The 100mbps technology will be based on a combination of fiber optics and ethernet — a kind of a wire currently used in offices to connect PCs on a LAN. “We will supply fibre optics from our exchanges to the premises of a housing complex. A special installation at the base of building will then carry internet (data) to individual flats through ethernet at 100 mbps,” Mr Chakravarti said.

He added: “The second project involves supplying direct fibre optics to individual houses. This technology is technically termed passive optical network (PON) and allows speeds of 500 mbps. A passive optical network (PON) is a point-to-multipoint, fiber to the premises network architecture in which unpowered optical splitters are used to enable a single optical fiber to serve multiple premises, typically 32. PON does not require those installations necessary for FTTP.” “We have decided to install and test this technology. The project will be initiated next month and will be rolled out as demand for faster broadband rises,” he said.

The broadband technology that offers 2mpbs requires fibre optics to the exchanges. Rest is through copper wire. FTTP is through supply of fibre optics to premises and PON is supply of fibre optics to individual homes. All these will be offered in stages. Interestingly, price of fibre optics have declined by as much as 20% every year over the last three years making these technologies affordable.

“Possibilities are immense. PON will allow video conferencing from home. Professors and teachers will be able to hold virtual classes while doctors will be able to examine their patients from home through a very high resolution image transfer process. It will open a new world of possibilities,” the CGM explained.

Future's 5 hottest technologies

Source: http://infotech.indiatimes.com/quickiearticleshow/3431341.cms

The research agency Gartner Inc has identified emerging technologies for future and predicts that these will have a transformational business impact. According to the report "Hype Cycle for Emerging Technologies, 2008," these should be considered for adoption by technology planners in the next 10 years. "Although Web 2.0 is now entering the trough of disillusionment, it will emerge within two years to have transformational impact, as companies steadily gain more experience and success with both the technologies and the cultural implications," said Jackie Fenn, vice president, Gartner. "Later -- in between two and five years -- cloud computing and service-oriented architecture (SOA), which is moving up the slope of enlightenment, will deliver transformation in terms of driving deep changes in the role and capabilities of IT,” he adds.

So, here’s looking into the emerging technologies for future.

1. Green IT
Along with broader societal pressure for environmentally sustainable solutions, IT has the opportunity -- and in many cases, a requirement -- to improve the "greenness" of its own activities, as well as to contribute to broader company and industry environmental initiatives.

2. Cloud Computing
As companies seek to consume their IT services in the most cost-effective way, interest is growing in drawing a broad range of services (for example, computational power, storage and business applications) from the "cloud," rather than from on-premises equipment. Many types of technology providers are aligning themselves with this trend, with the result that confusion and hype will continue for at least another year before distinct submarkets and market leaders emerge.

3. Social computing platforms
Following the phenomenal success of consumer-oriented social networking sites, such as MySpace and Facebook, companies are examining the role that these sites, or their enterprise-grade equivalents, will play in future collaboration environments. The scope is also expanding to incorporate the notion of social "platforms," or environments for a broad range of developers to build on the basic application.

4. Video Telepresence
High-end videoconferencing systems (for example, from HP, Cisco, Teliris and others) that utilise large, high-definition (HD) displays and components to show life-size images of participants in meeting rooms or suites have proven significantly more effective than earlier generations of video conferencing technology. High cost is currently the barrier to broader adoption.

5. Microblogging
Pioneered by Twitter (although other services such as FriendFeed or Plurk are also available), microblogging is a relatively new addition to the world of social networking. In this contributors post a stream of very short messages (fewer than 140 characters) providing information about their current activity or thoughts, which can then be subscribed to by others. The phenomenon has caught on among certain online communities, and leading-edge companies are investigating its role in enhancing other social media and channels.

New Fuel Cell System 'Generates Electricity with Only Water, Air'

Prototyped vehicle
120W fuel cell system

Genepax Co Ltd explained the technologies used in its new fuel cell system "Water Energy System (WES)," which uses water as a fuel and does not emit CO2.
The system can generate power just by supplying water and air to the fuel and air electrodes, respectively, the company said at the press conference, which took place June 12, 2008, at the Osaka Assembly Hall.
The basic power generation mechanism of the new system is similar to that of a normal fuel cell, which uses hydrogen as a fuel. According to Genepax, the main feature of the new system is that it uses the company's membrane electrode assembly (MEA), which contains a material capable of breaking down water into hydrogen and oxygen through a chemical reaction.
Though the company did not reveal the details, it "succeeded in adopting a well-known process to produce hydrogen from water to the MEA," said Hirasawa Kiyoshi, the company's president. This process is allegedly similar to the mechanism that produces hydrogen by a reaction of metal hydride and water. But compared with the existing method, the new process is expected to produce hydrogen from water for longer time, the company said.
With the new process, the cell needs only water and air, eliminating the need for a hydrogen reformer and high-pressure hydrogen tank. Moreover, the MEA requires no special catalysts, and the required amount of rare metals such as platinum is almost the same as that of existing systems, Genepax said.
Unlike the direct methanol fuel cell (DMFC), which uses methanol as a fuel, the new system does not emit CO2. In addition, it is expected to have a longer life because catalyst degradation (poisoning) caused by CO does not occur on the fuel electrode side. As it has only been slightly more than a year since the company completed the prototype, it plans to collect more data on the product life.
At the conference, Genepax unveiled a fuel cell stack with a rated output of 120W and a fuel cell system with a rated output of 300W. In the demonstration, the 120W fuel cell stack was first supplied with water by using a dry-cell battery operated pump. After power was generated, it was operated as a passive system with the pump turned off.
This time, the voltage of the fuel cell stack was 25-30V. Because the stack is composed of 40 cells connected in series, it is expected that the output per cell is 3W or higher, the voltage is about 0.5-0.7V, and the current is about 6-7A. The power density is likely to be not less than 30mW/cm2 because the reaction area of the cell is 10 x 10 cm.
Meanwhile, the 300W fuel cell system is an active system, which supplies water and air with a pump. In the demonstration, Genepax powered the TV and the lighting equipment with a lead-acid battery charged by using the system. In addition, the 300W system was mounted in the luggage room of a compact electric vehicle "Reva" manufactured by Takeoka Mini Car Products Co Ltd, and the vehicle was actually driven by the system.
Genepax initially planned to develop a 500W system, but failed to procure the materials for MEA in time and ended up in making a 300W system.
For the future, the company intends to provide 1kw-class generation systems for use in electric vehicles and houses. Instead of driving electric vehicles with this system alone, the company expects to use it as a generator to charge the secondary battery used in electric vehicles.
Although the production cost is currently about ¥2,000,000 (US$18,522), it can be reduced to ¥500,000 or lower if Genepax succeeds in mass production. The company believes that its fuel cell system can compete with residential solar cell systems if the cost can be reduced to this level
