Researchers at North Carolina State University have reportedly developed a new form of graphene technology that is claimed to be suitable for electronics cooling systems. The copper-graphene composite materials are said to bring a 25 percent improvement in thermal conductivity compared to pure copper.
Korean researchers have developed flexible transistors using graphene to accomplish the feat. The researchers had experimented with a range of conventional materials including molecules, polymers and metals but found them to be ineffective for this purpose. Graphene has an advantage in that it can be integrated using the traditional printing processes at room temperatures without vacuum or high-temperature steps.
British scientists have discovered a way to transmit light much more efficiently than current fiber optic technology. The technique uses increasingly popular graphene in conjunction with tiny metallic structures known as plasmonic nanostructures. The combination could transfer information at speeds tens or potentially hundreds of times faster than the fastest Internet cables available today.
Scientists at the University of California, Berkeley have showed off graphene-based technology that could bring much faster digital communications speeds. An experimental optical device was created that uses graphene, a one-atom-thick layer of crystallized carbon, that switches light on and off much faster than current network modulator technologies. The team, lead by engineering professor Xiang Zhang, believes it can eventually scale its technology up to 500GHz, which is much faster than current 1GHz tech.
Researchers from the University of Illinois may have found a way of creating transistors from graphene that have a unique self-cooling property. Current limitations of computer chips made from silicon revolve around the way they generate heat which often require an external cooling source. This affects the size of the chips and how efficient they can be. The new technique using graphene could deliver smaller, more powerful chips that could require little or no cooling at all.
A recent report from the Massachusetts Institute of Technology (MIT) is naming Graphene, a form of pure carbon founded in 2004 that could be applied to microchips to make for faster processing speeds than is possible with current silicon chips. Researchers outside of MIT have created prototype transistors and similar simple devices using one-atom thick Graphene, but the newer MIT findings could make for more advanced applications. The researchers built an experimental Graphene chip that acts as a frequency multiplier, capable of doubling the frequency of an electromagnetic signal, or effectively doubling a CPU's clock speed.

WaterField cycling ride pouches
WaterField's new cycling ride pouches are custom-fit to carry both in one compact kit and are ready for the summer cycling season. The Cycling Ride Pouch includes a clear window that allows basic phone access with the phone still safely within the case, and the Cycling Club Pouch incorporates a padded phone pocket to separate up to an iPhone 6 Plus-sized phone from the tool compartment. Both handsome pouches fit neatly in a back jersey pocket, with optimized surface area for comfort. The Cycling Ride Pouch sells for $80, with the Club Pouch retailing for $50. http://bit.ly/1rRqN4e
Dish providing on-site iPhone repair services
Dish has expanded into the iPhone repair industry. Available today, the satellite television company's "Smart Phone Repair" routes a technician directly to a customer's door. DISH's network of technicians in all 50 states will repair cracked screens and replace batteries on Apple's iPhone 5, 5c, 5s, 6 and 6 Plus. In the coming months, the company intends to expand its service to include additional devices and smartphone accessories. http://bit.ly/1SLaDiW
India rejects Apple's refurb request
Apple's request to the Indian government to be allowed to sell refurbished iPhones has been rejected, a move that will hurt the company's efforts to attract budget-oriented consumers. Opposition to the importation of refurbished iPhones is said to have been led by local smartphone makers (and, it should be noted, Samsung), who feared that lower-cost iPhones would undermine the government's own mandates on manufacturing phones in India, and trigger a flood of used electronics into the marketplace, driving prices generally downward. Currently, Apple has just two percent of the smartphone market there, and is also applying to the government for permission to open directly-controlled Apple Stores. That decision is still pending. http://bloom.bg/1rRgi0I
Amazon Prime Now available via website
Amazon's Prime Now rapid delivery service is now available to use from the web, giving users an alternative to using the normal mobile app. Available as a free option for Prime subscribers in certain areas, the web-based service continues to offer the same selection of goods as the mobile version, and is still free for deliveries within two hours, $8 for within one hour. http://amzn.to/1UvqYgi
SoundCloud Go expands to UK, Ireland
SoundCloud has expanded its subscription service to the United Kingdom and Ireland, its first expansion since launching in the United States in late March. Priced at £10 ($14) per month, SoundCloud Go lets users listen to existing tracks ad-free, as well as complete access to licensed music from major record labels, and the ability to download tracks for offline listening. http://bit.ly/1rhBv35
Maps adds transit for Rio Olympics
On Monday, Apple added public transit directions for Rio de Janeiro in Brazil to its Apple Maps program in advance of the 2016 Summer Olympics, which begin on August 5. The addition marks the first time a Brazilian city has gotten the upgraded public transit maps, which include station maps as well as transit schedules and tracking. The transit directions cover ferries as well as bus, subway, and light rail lines. The company has recently expanded transit directions to Montreal in Canada, and Seattle, Portand (Oregon), and other US cities.
