Here's the world's first giant-screen Windows Phone, the Nokia Lumia 1520

Here's the world's first giant-screen Windows Phone, the Nokia Lumia 1520 | Online Exams | Scoop.it

Nokia announced the world's first giant-sized Windows Phone, the Lumia 1520. It will have a 6-inch screen, which makes the phone's display a full inch larger than Samsung's Galaxy S4 and two inches larger than Apple's iPhone 5S. It's also the first phone to take advantage of the newest version of Microsoft's Windows Phone 8 software, which has been designed to work on giant "phablets" (part phone, part tablet).

A phablet why not, but if you do want to make a phone call, best not to hold the thing to your ear: you may look ridiculous. Invest in a Bluetooth headset and yammer away with your phablet hidden.

that is really cool. i was actually just asking myself the other day when they were going to come out with the next nokia lumia, and now i have an answer. i originally wanted the 1020 for christmas, but now i want the 1520. it looks really awesome.

Why Apple's A7 chip will really shine in the iPad Air

Why Apple's A7 chip will really shine in the iPad Air | Online Exams | Scoop.it

The new A7 processor in Apple's latest tablets and phones will help that even more. At first glance, this is nothing new. Every processor generation ends up being faster and more energy efficient in some way or another, so it's rare that a new CPU itself ends up being news outside of hardcore PC enthusiast circles.

Researchers Develop Design to Seamlessly Integrate Electronic Circuits onto Graphene

Researchers Develop Design to Seamlessly Integrate Electronic Circuits onto Graphene | Online Exams | Scoop.it
UC Santa Barbara researchers have demonstrated a seamless design of an atomically-thin circuit with transistors and interconnects etched onto a seemingly impossible single layer of graphene.

 

The demonstration offers possibilities for ultra energy-efficient, flexible, and transparent electronics. Bulk materials commonly used to make CMOS transitors and interconnects pose fundamental challenges in continuous shrinking of their feature-sizes and suffer from increasing "contact resistance" between them, both of which lead to degrading performance and rising energy consumption.

"In addition to its atomically thin and pristine surfaces, graphene has a tunable band gap, which can be adjusted by lithographic sketching of patterns - narrow graphene ribbons can be made semiconducting while wider ribbons are metallic. Hence, contiguous graphene ribbons can be envisioned from the same starting material to design both active and passive devices in a seamless fashion and lower interface/contact resistances," explained Kaustav Banerjee, professor of electrical and computer engineering and director of the Nanoelectronics Research Lab at UCSB. Banerjee's research team also includes UCSB researchers Jiahao Kang, Deblina Sarkar and Yasin Khatami.

 

"Accurate evaluation of electrical transport through the various graphene nanoribbon based devices and interconnects and across their interfaces was key to our successful circuit design and optimization," explained Jiahao Kang, a PhD student in Banerjee's group and a co-author of the study. Banerjee's group pioneered a methodology using the Non-Equilibrium Green's Function (NEGF) technique to evaluate the performance of such complex circuit schemes involving many heterojunctions. This methodology was used in designing an "all-graphene" logic circuit reported in this study.

"atomically-thin circuit", this is amazing!  I remember GPS receivers that were 15 pounds, now they are in cell phones.
