BSNL launches new tablet


BSNL has launched three tablets including two 7 inch resistive screen based tabs with Android 2.3 operating system while the third tablet comes with an 8 inch capacitive touchscreen.

Made by Noida based company - Pantel, the tablets will be sold with discounted data plans from BSNL. The three tablets are priced at Rs 3,250, Rs 10,999 and Rs 13,500.
The cheapest model is Panta Tpad IS 701r which is priced at Rs 3,250. Notably, Aakash is priced at just Rs 2500. However, Tpad has better specification than the Datawind's low cost tablet.

Panta Tpad is a WiFi only tablet with Android 2.3 operating system, it has a 1 GHz processor (ARM11 IMAP210) clubbed with 256 MB RAM. The tablet also offers HDMI port through which it can be connected to a TV. Its 7 inch resistive touch screen comes with 800x600 resolution and 16:9 aspect ratio.

The tablet has a 3000 mAh battery and 2 GB internal memory which can be expanded through micro SD card. The tablet also has a VGA front facing camera for video calling. While Panta Tpad IS 701r has the BSNL branding, the other two tablets images do not have.
The second tablet is named 'Panta Tpad_ws704c'. It has the same specification as its cheapest cousin (701r) but offers added 3G connectivity which supports both CDMA/EVDO and GSM, inbuilt A-GPS, Accelerometer and Bluetooth. It also comes with a 2 megapixel rear camera and also has bigger 512 MB RAM for faster performance.

The costliest amongst the three is the Tpad WS802C which has an 8 inch capacitive screen. It comes with a faster 1.2 GHz processor and 512 MB RAM. The internal memory is also bigger at 4 GB. Rest of the features like GPS, camera and Bluetooth are same as the 704C.

Amazon’s Kindle fire launched for $199


Bangalore: Amazon launched its much awaited Kindle fire tablet for $199, the latest--and possibly biggest--challenger to Apple Inc.'s dominant iPad.The $199 device that will run on modified version of Google's Android operating system has a 7-inch screen nd can access Amazon's app store, streaming movies and TV shows.
The tablet will go on sale from Nov 15 and the pre-orders will start from today.
Amazon's CEO Jeff Bezos said, "We asked ourselves, Is there some way we can bring all of these things together [web service, Prime, Kindle, instant video and its app store] into a remarkable product offering customers would love. Yes there is Kindle Fire," during the launch.
The cheapest new Kindle will cost $79, and dispenses with the keyboard the Kindles have carried since the first model launched in 2007. Previously, the cheapest Kindle cost $114.
Amazon is also bringing out the first black-and-white Kindle with a touch screen. It will cost $99 and is reminiscent of Barnes & Noble's latest Nook. A version with access to AT&T's cellular network for book downloads will cost $149.
Bezos said that most of the content is backed up in the cloud, and that the device features wireless synching. The specifications are however lower when compared to higher end tablets in the category. Though it has a dual core processor and is 3G enabled, it lacks other features like camera and a microphone. Fire includes an IPS display, an ultra-wide viewing angle, and fast dual-core processor
On the e-reader front, Bezos said the Kindle Touch e-book includes an advanced E Ink display, infrared touch interface, extra long battery life, access to millions of e-books, free storage in the Amazon Cloud, Audible integration, and more, including a feature known as X-Ray, which shows the "bones" of a book, or details Amazon thinks a reader would find interesting.
It would be interesting to see how it survives in an already crowded tablet market. So far Apple's iPad has been the most popular tablet for its ease of use, elegant design and selection of over 90,000 apps. The iPad has sold 29 million versions since its introduction, owning more than two-thirds of the market.
So far, iPad rivals like HP's touchpad, Research in Motion's Playbook, Samsung Electronics Co. Ltd.'s Galaxy Tab and Motorola Mobility Holdings Inc.'s Xoom have failed to attract mass audiences.
For Amazon, its relationships with its users could be its biggest advantage and also the smart pricing might help them.

Some examples of how nanotechnology impacts our lives now

A plastic nanocomposite is being used for "step assists" in the GM Safari and Astro Vans. It is scratch-resistant, light-weight, and rust-proof, and generates improvements in strength and reductions in weight, which lead to fuel savings and increased longevity. And in 2001, Toyota started using nanocomposites in a bumper that makes it 60% lighter and twice as resistant to denting and scratching.
Impact: Will likely be used on other GM and Toyota models soon, and in other areas of their vehicles, as well as the other auto manufactures, lowering weight, increasing milage, and creating longer-lasting autos. Likely to impact repair shops (fewer repairs needed) and auto insurance companies (fewer claims). Will also likely soon be seen everywhere weight, weather-proofing, durability, and strength are important factors. Expect NASA, the ESA, and other space-faring organizations to take a serious look, soon, which will eventually result in lower lift costs, which will result in more material being lifted into space. 

Strong and light sounds like the perfect recipe for a golf club, of course, which is why so many golf club manufacturers are now devoting big bucks to nano R&D. Thus far, the only company among the big boys to convert research into tangible products is Wilson, which offers three drivers, a fairway wood, four balls and even a golf bag made using nano-materials. 

Nanocrystals


Examples: "Metal nanocrystals might be incorporated into car bumpers, making the parts stronger, or into aluminum, making it more wear resistant. Metal nanocrystals might be used to produce bearings that last longer than their conventional counterparts, new types of sensors and components for computers and electronic hardware.

Nanocrystals of various metals have been shown to be 100 percent, 200 percent and even as much as 300 percent harder than the same materials in bulk form. Because wear resistance often is dictated by the hardness of a metal, parts made from nanocrystals might last significantly longer than conventional parts." 
Nanocrystals absorb then re-emit the light in a different color -- the size of the nanocrystal (in the Angstrom scale) determines the color.

Six different quantum dot solutions are shown, excited with a long-wave UV lamp.

Quantum dots are molecular-scale optical beacons. Qdot™ nanocrystals behave like molecular LEDs (light emitting diodes) by "lighting up" biological binding events with a broad palette of applied colors. 


Nanostructured Materials


     Example:
 Nanodyne makes a tungsten-carbide-cobalt composite powder (grain size less than 15nm) that is used to make a sintered alloy as hard as diamond, which is in turn used to make cutting tools, drill bits, armor plate, and jet engine parts.
Impact: Every industry that makes parts or components whose properties must include hardness and durability. 

Nanoclays and Nanocomposites


     Example:
 Used in packaging, like beer bottles, as a barrier, allowing for thinner material, with a subsequently lighter weight, and greater shelf-life.
Impact: $480B packaging and $300B plastics industries. Reduced weight means transportation costs decline. Changing from glass and aluminum - think beer and soda bottles - to plastic reduces production costs. Nanoclays help to hold the pressure and carbonation inside the bottle, increasing shelf life. It is estimated that beer in these containers will gain an extra 60 days (from 120 to 180) of shelf life, reducing spoilage, and decreasing overall costs to the end user. Nanocor is one company producing nanoclays and nanocomposites, for a variety of uses, including flame retardants, barrier film (as in juice containers), and bottle barrier (as shown above). "They are not only used to improve existing products, but also are extending their reach into areas formerly dominated by metal, glass and wood."

Nanocatalysts


     Examples:
 China's largest coal company (Shenhua Group) has licensed technology from Hydrocarbon Technologies that will enable it to liquify coal and turn it into gas. The process uses a gel-based nanoscale catalyst, which improves the efficiency and reduces the cost.
Impact: "If the technology lives up to its promise and can economically transform coal into diesel fuel and gasoline, coal-rich countries such as the U.S., China and Germany could depend far less on imported oil. At the same time, acid-rain pollution would be reduced because the liquefaction strips coal of harmful sulfur."
