Carbon is proving to be a very useful substance for many applications. A 2D, single atomic layer of carbon, called graphene, could provide the ideal, nearly transparent electrode material for future displays and solar cells, and one which will not further deplete our already scarce supply of indium.
Stanford (CA) - Researchers at Stanford University have discovered a way to utilize silicon nanowires in such a way as to reinvent the rechargeable Lithium-Ion battery. This find produces 10x the electricity of existing Li-ion batteries, leading to the 20-hour notebook. The lead researcher is calling it "a revolutionary development".
The coral reefs are providing early signs as to the perilous conditions of our oceans. Too much acid, too much salt, and too much CO2 in the Earth's atmosphere increasing the temperature. Changes need to be enacted soon to keep the coral reefs from dying by 2100, and an irreversible trend beginning.
Los Angeles (CA) - A team of UCLA researchers has been able to increase the performance of transistors by at least 5% without changing anything in the manufacturing process. Instead, they looked only at the up-front design used to create the circuit's shape. The research produced wires that were 30% shorter than standard models, as are used for logic gates, interconnects and nodes. They've found that by only optimizing the layout during the computer design stage, additional performance and speed is achievable without any other considerations.
Argonne (IL) - A newly published research finding at Argonne National Laboratory has identified a hybrid organic/inorganic material with zero thermal expansion (ZTE) that is proving suitable for use in semiconductors. Such ZTE products would allow for a much wider operational temperature range, resulting in faster clock rates and higher performing computers.
Taipei (Taiwan) - The silicon wafers used for the solar cell industry have increased significantly in price this quarter. 6" wafers are currently priced between $9.20 and $9.30 each. The Taiwanese solar cell makers claim this is an unacceptably high price. When the wafers exceeded $9 in November there was an outcry. The additional 3% has pushed the price beyond $9, what was considered to be the ceiling. As a result, silicon solar cell makers are now forced to reduce the number of products they buy, sending ripples downstream to end-produ
An ancient magnetic mineral called lodestone is proving somewhat baffling to modern scientists. By using a new generation of nano-tools, researchers have been able to un-earth a new ability that could have applications in mass storage or computer memory.
Copenhagen (Denmark) - Martin Aagesen, a PhD from the Nano-Science Center at the Niels Bohr Institute at the University of Copenhagen, discovered a new, untried material, called silicium. He describes it as "a perfect crystalline structure". The new material has the ability to absorb all light, and he claims it could become "the perfect solar cell". According to early reports, 30% efficiencies seem well within reach, though there are very few details in his findings.
While Gartner projects phishing and malware attacks will to become increasingly piercing through 2009, in 2007 the damage was done. 3.6 million U.S. adults lost $3.2 billion to phishing schemes.
A paid, professional DRAM industry forecaster see only one activity which could turn the DRAM industry's slump around, that of big corporate buying spree for the new year. Let's hope it's time to upgrade those machines.
Tucson (AZ) - An all-electric dragster named Current Eliminator V, has set a National Hot Rod Association's Super Pro class quarter-mile world speed record. Coming in at 8.10 seconds, and a top speed of 153.6 mph, the car, driven by Dennis Berube, was powered by the same type of battery which accelerated the Killacycle to a whopping 168 mph in 7.824 seconds in a quarter mile just a month prior.
A new proposal to bring 4x faster speeds over FireWire 800 is approaching the final ratification phase. Beginning in February, 2008, a 3.2 Gbps FireWire could be standard fare for future machines, using the same cables and connectors.
