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.

Cirrus creates Lightning-headphone dev kit
Apple supplier Cirrus Logic has introduced a MFi-compliant new development kit for companies interested in using Cirrus' chips to create Lightning-based headphones, which -- regardless of whether rumors about Apple dropping the analog headphone jack in its iPhone this fall -- can offer advantages to music-loving iOS device users. The kit mentions some of the advantages of an all-digital headset or headphone connector, including higher-bitrate support, a more customizable experience, and support for power and data transfer into headphone hardware. Several companies already make Lightning headphones, and Apple has supported the concept since June 2014. http://bit.ly/29giiZj
Apple Store app offers Procreate Pocket
The Apple Store app for iPhone, which periodically rewards users with free app gifts, is now offering the iPhone "Pocket" version of drawing app Procreate for those who have the free Apple Store app until July 28. Users who have redeemed the offer by navigating to the "Stores" tab of the app and swiping past the "iPhone Upgrade Program" banner to the "Procreate" banner have noted that only the limited Pocket (iPhone) version of the app is available free, even if the Apple Store app is installed and the offer redeemed on an iPad. The Pocket version currently sells for $3 on the iOS App Store. [32.4MB]
Porsche adds CarPlay to 2017 Panamera
Porsche has added a fifth model of vehicle to its CarPlay-supported lineup, announcing that the 2017 Panamera -- which will arrive in the US in January -- will include Apple's infotainment technology, and be seen on a giant 12.3-inch touchscreen as part of an all-new Porsche Communication Management system. The luxury sedan starts at $99,900 for the 4S model, and scales up to the Panamera Turbo, which sells for $146,900. Other vehicles that currently support CarPlay include the 2016 911 and the 2017 models of Macan, 718 Boxster, and 718 Cayman. The company did not mention support for Google's corresponding Android Auto in its announcement. http://bit.ly/295ZQ94
Apple employees testing wheelchair features
New features included in the forthcoming watchOS 3 are being tested by Apple retail store employees, including a new activity-tracking feature that has been designed with wheelchair users in mind. The move is slightly unusual in that, while retail employees have previously been used to test pre-release versions of OS X and iOS, this marks the first time they've been included in the otherwise developer-only watchOS betas. The company is said to have gone to great lengths to modify the activity tracker for wheelchair users, including changing the "time to stand" notification to "time to roll" and including two wheelchair-centric workout apps. http://bit.ly/2955JDa
SanDisk reveals two 256GB microSDXC cards
SanDisk has introduced two 256GB microSDXC cards. Arriving in August for $150, the Ultra microSDXC UHS-I Premium Edition card offers transfer speeds of up to 95MB/s for reading data. The Extreme microSDXC UHS-I card can read at a fast 100MB/s and write at up to 90MB/s, and will be shipping sometime in the fourth quarter for $200. http://bit.ly/294Q1If
Apple's third-quarter results due July 26
Apple has advised it will be issuing its third-quarter results on July 26, with a conference call to answer investor and analyst queries about the earnings set to take place later that day. The stream of the call will go live at 2pm PT (5pm ET) via Apple's investor site, with the results themselves expected to be released roughly 30 minutes before the call commences. Apple's guidance for the quarter put revenue at between $41 billion and $43 billion. http://apple.co/1oi1Pbm
Twitter stickers slowly roll out to users
Twitter has introduced "stickers," allowing users to add extra graphical elements to their photos before uploading them to the micro-blogging service. A library of hundreds of accessories, props, and emoji will be available to use as stickers, which can be resized, rotated, and placed anywhere on the photograph. Images with stickers will also become searchable with viewers able to select a sticker to see how others use the same graphic in their own posts. Twitter advises stickers will be rolling out to users over the next few weeks, and will work on both the mobile apps and through the browser. http://bit.ly/29bbwUE
