Samsung's Board has approved the separation of LCD business

Article first published as Samsung Board has approved the Spin-off of LCD businesses and operations on Technorati.


Samsung Electronics’ Board of Directors has approved the separation of LCD businesses and operations. The separated corporation will be launched by the company as Samsung Display Company Ltd. on 1 April. This new corporation will be started with a capital of 750 billion won ($668 million).
Although, the company has come closer to the separation of the company as a new entity after board’s approval but it still needs the approval of shareholders.
The company has taken this decision as the demand of LCD products is decreasing in this era of fast technological progresses and the company wants to keep in pace with new advancements. Moreover, the supply of LCD products has also been increased by manufacturers.
Samsung is the largest TV and flat screen manufacturer and the deceleration of the sale of LCD products could affect the company most. So, the company has planned to focus on the new technologies such as Organic Light Emitting Diode (OLED) to maintain competitiveness.
"The spin-off will allow us to make quicker business decisions and respond to our clients' needs more swiftly," said Donggun Park, executive vice president and head of Samsung's LCD business.
"Through enhancements in business competitiveness, we will continue to provide superior products and services for the market," he added.
Time will tell that this strategy of Samsung for increasing competency and operations will work or not.

Single atom transistor

Article first published as Transistor Made of Single Atom on Technorati.


Scientists from the University of New South Wales have developed the world’s smallest transistor that is made up of a single atom.
The team of researchers precisely placed the phosphorus-31 isotope on the Silicon base in an ultra-high vacuum chamber with the help of a Scanning Tunneling Microscope (STM) and developed a single atom transistor, which could be a better foundation for scalable quantum computing. Scientists have precisely positioned the atom, so that it must be at an effective place with reduced error margin.
“Our group has proved that it is really possible to position one phosphorus atom in a silicon environment - exactly as we need it - with near-atomic precision, and at the same time register gates,” lead author Dr. Martin Fuechsle from UNSW said.
Phosphorus-31 has been selected by the researchers as it has two possible nuclear spins and it could be an ideal isotope for solid-state quantum computing. Moreover, phosphorus and silicon would be compatible with the CMOS sensors used in processors these days.
“But this device is perfect”, says Professor Michelle Simmons, group leader and director of the ARC Centre for Quantum Computation and Communication Technology at UNSW. “This is the first time anyone has shown control of a single atom in a substrate with this level of precise accuracy.”
Single atom transistor would come in the processors in the near future as it is still a very expensive technology.
This research has been published online in the journal Nature Nanotechnology.

WiFi and processors in combination by Intel

Article first published as Combination of WiFi and Processors on a Single Chip is Among Intel’s Next Projects on Technorati.


Intel Corp. has unveiled a small device dubbed “Rosepoint” at International Solid-State Circuits Conference (ISSCC) this week. This small device is a 32nm system-on-chip (SoC) has an integrated digital 2.4 GHz WiFi radio with a dual-core Intel Atom Processor. According to the company, this small device can be not only miniaturized but also will result in low cost fitting in mobile devices.
“Energy efficiency has been Intel’s goal for many years now,” said Justin Rattner, chief technology officer at Intel, in a call with reporters. “We do it to minimize the energy impact on the environment but also to make Intel’s products more scalable across the computing continuum.”
The company has to work a lot in this regard as this breakthrough design needs a lot of research due to the interference caused by the wireless radio and processors’ radiations’ interference. The company has to develop a cover up material that can not only protect against radiation but also has noise-cancelling methods, so that both the components may exist on the same chip without disrupting each other.
The company is also thinking on the addition of digital cellular radio chip in the near future. According to the company, such technology will come in the market by three years or so.

Stronger adhesion gained through biomimetics

Article first published as Substance From Gecko Feet Holds a Lot of Weight on Technorati.


Researchers from University of Massachusetts Amherst have developed very strong sticky substance that has the ability to hold 318 kg or 700 pounds of a substance on a smooth wall without slipping.
Researchers extensively studied the adhesive forces in the feet of gecko, which is a small tropical lizard with hooked ridges in feet allowing it to climb smooth vertical surfaces. The sticky nature in the feet of gecko is able to hold 4 kg of material on the wall, without slipping, as it has high-capacity, dry and reversible in nature.
They have named “Geckskin” to the adhesive material.
"Our Geckskin device is about 16 inches square, about the size of an index card, and can hold a maximum force of about 700 pounds while adhering to a smooth surface such as glass." said Alfred J. Crosby from Department of Biology, University of Massachusetts, Amherst, and one of the authors in this study.
Geckskin can be released from the wall or attaching surface with negligible efforts despite of its highly strong sticking ability. After release it can be used many times without any loss of effectiveness. Researchers have reported that it can attach a 42-inch television on the wall, can be released from the wall with little force and can be attached on any other surface without leaving any residue behind.
The researchers have published their findings in the journal of Advanced Materials.
