World's Smallest Desktop- Lenovo

One of the Major Electronics Lenovo said that they got succeed in launching the World Smallest Desktop and now they are continuing their efforts in improving in this Field.
ThinkCentre M72e
The desktop ThinkCentre M72e and ThinkCentre M92p small desktop PC's are the cost of Rs. 23,500 (excluding taxes and operating system).
The company has said that this products is not only cover less space but offer Superior Performance and Reliability.
Now the companies prefer to launch small desktops so that it will occur less space but yet perform at high level.

Samsung with its New Windows Tablet

Tech giant Samsung has approved that it plans to come out with a new aspect with Windows Tablet. Samsung has said that it is working on a new tablet that will run the Windows Rt OS. This tablet is expected to launch in October 2012 this year.

                                   


It's been ups and downs for Samsung this past few days, but also mentioned that Samsung  has the breaking record profit this week. We will appreciate Samsung's work and hope it will be a great success for Samsung in future with these gadgets.
Unicornix will soon present its review when we will have the gadget in the Market.

Batteries charge quickly and retain capacity

The batteries in Illinois professor Paul Braun's lab look like any others, but they pack a surprise inside. 

Braun's group developed a three-dimensional nanostructure for battery cathodes that allows for dramatically faster charging and discharging without sacrificing energy storage capacity. The researchers' findings would be reported in the March 20 advance online edition of the journal Nature Nanotechnology. 
Aside from quick-charge consumer electronics, batteries that can store a lot of energy, release it fast and recharge quickly are desirable for electric vehicles, medical devices, lasers and military applications. 

"This system that we have gives you capacitor-like power with battery-like energy," said Braun, a professor of materials science and engineering. "Most capacitors store very little energy. They can release it very fast, but they can't hold much. Most batteries store a reasonably large amount of energy, but they can't provide or receive energy rapidly. This does both". 

The performance of typical lithium-ion (Li-ion) or nickel metal hydride (NiMH) rechargeable batteries degrades significantly when they are rapidly charged or discharged. Making the active material in the battery a thin film allows for very fast charging and discharging, but reduces the capacity to nearly zero because the active material lacks volume to store energy. 

Braun's group wraps a thin film into three-dimensional structure, achieving both high active volume (high capacity) and large current. They have demonstrated battery electrodes that can charge or discharge in a few seconds, 10 to 100 times faster than equivalent bulk electrodes, yet can perform normally in existing devices. 

This kind of performance could lead to phones that charge in seconds or laptops that charge in minutes, as well as high-power lasers and defibrillators that don't need time to power up before or between pulses. 

Braun is especially optimistic for the batteries' potential in electric vehicles. Battery life and recharging time are major limitations of electric vehicles. Long-distance road trips can be their own form of start-and-stop driving if the battery only lasts for 100 miles and then requires an hour to recharge. 

"If you had the ability to charge rapidly, instead of taking hours to charge the vehicle you could potentially have vehicles that would charge in similar times as needed to refuel a car with gasoline," Braun said. "If you had five-minute charge capability, you would think of this the same way you do an internal combustion engine. You would just pull up to a charging station and fill up". 

All of the processes the group used are also used at large scales in industry so the technique could be scaled up for manufacturing. 

They key to the group's novel 3-D structure is self-assembly. They begin by coating a surface with tiny spheres, packing them tightly together to form a lattice. Trying to create such a uniform lattice by other means is time-consuming and impractical, but the inexpensive spheres settle into place. 

automatically. 

Then the scientists fill the space between and around the spheres with metal. The spheres are melted or dissolved, leaving a porous 3-D metal scaffolding, like a sponge. Next, a process called electropolishing uniformly etches away the surface of the scaffold to enlarge the pores and make an open framework. Finally, the scientists coat the frame with a thin film of the active material. 

The result is a bicontinuous electrode structure with small interconnects, so the lithium ions can move rapidly; a thin-film active material, so the diffusion kinetics are rapid; and a metal framework with good electrical conductivity. 

The group demonstrated both NiMH and Li-ion batteries, but the structure is general, so any battery material that can be deposited on the metal frame could be used. 

"We like that it's very universal, so if someone comes up with a better battery chemistry, this concept applies," said Braun, who is also affiliated with the Materials Research Laboratory and the Beckman Institute for Advanced Science and Technology at Illinois. "This is not associated with one very specific kind of battery, but rather it's a new paradigm in thinking about a battery in three dimensions for enhancing properties".
