Method Created for Synthesizing Graphene on Silicon Chips
Since its discovery, many researchers from around the world have been working to bring graphene to electronics, and we may be one giant step closer to realizing this. Researchers at Korea University have found a way to grow graphene on silicon, making it possible to integrate the material into silicon microelectronics.
Graphene was first discovered in 2004 and is the first 2D material we ever created. It is considered two dimensional because a single layer is just one atom thick, making it the thinnest material known to humanity. In addition to that distinction, it also possesses a number of extraordinary properties, including exceptionally high electron mobility, strength, and flexibility. These would make it ideal for electronics, but the normal means of producing it, chemical vapor deposition, is not compatible for silicon manufacturing. The Korean researchers' new method however is able to grow the graphene directly on silicon and silicon oxide by utilizing ion implantation. This works by accelerating carbon ions with an electric field into a layered surface of nickel, silicon dioxide, and silicon. The nickel acts as a catalyst for producing graphene during an activation annealing process.
Along with the ability to grow graphene directly on the silicon materials, this method also allows the properties of the graphene layers to be tuned, such as their thickness. Perhaps most importantly though is the fact that this method can produce graphene sheets with four-inch diameters, and it should be possible to scale them up to the size of silicon wafers. Now the researchers are working to lower the temperatures involved and to better control the thickness of the layers.

Hardware Roundup: Wednesday, July 22, 2015, Edition
The middle of the week is upon us, with a few items to interest you this day. We have a review of the Deepcool Assassin II CPU cooler, a dual tower packing two fans, eight heat pipes, and its own four-port fan hub. There is also a look at the Acer Aspire V 15 Nitro Black Edition gaming laptop, which offers solid performance without costing you an arm and a leg. Wrapping things up for today is the VKWorld VK6735 smartphone, a budget-friendly model offering a 1GHz processor, 2GB of RAM, and Android 5.1.

Program Beats Humans at Recognizing Sketches
Personally I am not afraid that a robot-apocalypse will happen, but when I see news like this, I cannot help but feel we should be working harder to maintain our dominance. A recent study from Queen Mary, University of London has determined that the program Sketch-a-Net is better at identifying sketches than people. The program had a success rate of 74.9%, beating humans at our 73.1% rate.
Sketch-a-Net is a deep neural network, which means the program emulates how our brains process information, but its success comes from more than that. The program uses information that is normally discarded, including the order the strokes were made in, and it turns out that information is helpful for identifying the subject. The program does need all help it can get too, due to the abstract nature of sketches, compared to photographs. Still it was able to distinguish the finer details of some sketches, including identifying four different bird variants.
With the growing use of touchscreens, Sketch-a-Net and similar programs will become ever more important as a means to interface with our devices. It could also find more professional uses, such as in police forensics for identifying persons in mugshots or CCTV footage from artists' impressions, as well as image retrieval systems.

Leaked Benchmarks Compare Skylake Core i7-6700K and Devil’s Canyon Core i7-4790K
Chinese sources have leaked some intriguing benchmarks for the Core i7-6700K, Intel’s flagship 14nm Skylake processor that is expected to launch on August 5, 2015 at Gamescom. The benchmarks compare the Core i7-6700K against the flagship 22nm Devil’s Canyon processor, the Core i7-4790K. While separate motherboards were used for the benchmarks for compatibility reasons, the Intel Core i7-6700K certainly shines with its 10 to 15 percent increase in gaming performance and up to 30 percent increase in CPU performance. Besides the improved speed, the Core i7-6700K also boasts reduced power usage when compared to the Core i7-4790K, with the 14nm Skylake processor using 10W less at idle and 50W less at load in a similarly configured system. With the reduced power usage comes reduced temperatures as well, and it seems Intel has fixed the heating problem by the removal of on-board voltage regulator units. In the benchmarks, the Core i7-6700K ran between 55 and 65C on average while the Core i7-4790K ran at a blistering 90C on average.
For more specific benchmark results, as well as additional information on the motherboards utilized in the testing of the Intel CPUs, please see the source link below.
