Well, graphene can now add another statistic to its impressive resume now that researchers have confirmed it as the strongest material ever tested.

Two engineering professors at Columbia University tested graphene's strength at an atomic level by indenting a perfect sample of the material with a sharp probe made of diamond. The results confirm what many had suspected all along—and that will go a long way to bolster the case that graphene would be able to handle the heat produced in future ultrafast processors.

<![CDATA[ Scientists Build Nanowire Memory That Uses Trits, Not Bits ]]> Scientists at University of Pennsylvania have been tinkering with germanium-tellurium nanowires and have figured out how to make them store data in three states. Yup, that's 0,1 and 2... binary seems passé now doesn't it? According to the team, storing trits instead of bits "could allow for a huge increase in the memory density of potential future devices," meaning higher capacity storage in the same size. And using nanowires is a particularly good way to make memory chips because it may be possible to make them self-organize, making "top-down" silicon-chip fabrication seem clunky. The team's busy perfecting their understanding of nanowire size and chemistry, so don't expect to see results from the tech too soon. [Physorg]

<![CDATA[ Your Digital Camera Is Obsolete: Japanese Image Sensor 100x More Sensitive Than Current Chips ]]> Right now, your camera either has a CCD (most point and shoots) or a CMOS image sensor (lots of DSLRs) inside, which converts pretty pictures into an electrical signal. Japan's Research Center for Photovoltaics has developed a CIGS image sensor that's 100 times more light-sensitive than the silicon chip inside your cam. It's able to shoot in environments as dark as 0.001 lux, or about as dark as a "moonless clear night." Obviously, it'll be great for night vision gear, but it also picks up infrared, giving this some serious Sam Fisher applications. Check out the comparison shot between a CMOS and CIGS below, it's insane. Chen won't need that invisible coat, just a good zoom lens.

<![CDATA[ New Silicon Circuits Invented: Bendy, Stretchy, Rubbery ]]> Scientists have made a discovery that makes silicon cool again: it can now be made into bendy chips. Stiff silicon devices are powerful, of course, but not the best fit for some situations such as advanced medical sensors. Now a team University of Illinois at Urbana-Champaign has worked out a way to stick 1.5 micron-thick layers of silicon onto rubbery plastic in a way that actually makes it stretchable. Check out the video to see elastic integrated circuits in action.


All very cool, but what will it be used for? Well, stretchiness allows the material to be used in more places than simple "flexible" circuits. Once it's scaled up into real devices it could be used to make wearable computers, or to dot the exterior of aircraft with sensors. The Illinois team also predict it would be perfect for making sensors that wrap around the brain, making a powerful detector for seizures and other brain activity. [BBC News and New Scientist]

<![CDATA[ Silicon Out, Graphene In? ]]> graphene.gifPhysicists at the University of Maryland have demonstrated that graphene, a single-atom-thick sheet of graphite, has a greater ability to conduct electricity than any other known material at room temperature. In fact, electrons can travel up to 100 times faster in graphine than silicon, making it a likely candidate to replace it as a semiconductor material in devices like computer chips and sensors.

Graphene also has a resistivity (opposition to the flow of electric current) of 1.0 microOhm-cm—which is 35% less than copper. That figure would also make graphene the lowest resistivity material at room temperature. However, impurities in graphine make it less effective than copper at transferring electrons (at least for the moment). Still, with some refinement, the future looks promising for graphene as our next "miracle material." [University of Maryland via Slashdot]

<![CDATA[ Rough Nano-Wires Hold the Secret to Efficient Heat to Electricity Conversion ]]> The latest edition of Nature magazine details a new method scientists have derived for converting heat energy into electricity, using silicon to instigate the conversion. Researchers have more investigations to carry out, but if preliminary findings are indicative of what is to come, appliances that charge using your own body heat may be on the horizon.

Using "rough" silicon wires, produced by a process known as "electroless etching," where silicon nano-wires are synthesized in an aqueous solution, over a thin, semiconductor crystallized base, the scientists have been able to exploit the process of galvanic displacement of silicon. This displacement technique, which uses silver ions, causes the thermoelectric efficiency to be increased on the rough surfaces of the nano-wires.

The breakthrough comes from the boffins at the U.S. Department of Energy's (DOE) Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California, who believe they have found a way to increase the conversion efficiency by a factor of 100. Though they are unable to pin the exact physics of why this works, what they can be certain of is that it definitely does work.

The potential uses for such a technology are mind blowing; from power-jackets that recharge gadgets kept in their pockets to vehicles that utilizes your farts for headlight juice, and pretty much everything else in between. It will be a long while before anything like this makes it to the consumer market, but the development is an exciting one. Expect my son to blog about future developments concerning these nano-wires in 2016. [Tom's Hardware]

<![CDATA[ First Blu-ray BD Profile 1.1 Review (Verdict: Is That All?) ]]> The Players: Panasonic DMP-BD30 ($500) and Sony PlayStation 3 with 2.1 firmware ($400 to $500)
The Movies: Fox's Sunshine and Sony Pictures' Resident Evil: Extinction
The Challenge: To find out what's so special about Blu-ray's BD Profile 1.1, also known as Full Standard Profile or just simply "Picture-In-Picture Enabled"

Every new phase of technology has its first few tentative steps. Not only is Blu-ray in its earliest stage, but that stage seems to be subdivided into a few mini-stages. As we talked about in The State of Blu-ray, most Blu-ray players today are Profile 1.0, which means they play Blu-ray movies (usually).

The two above are currently available with Profile 1.1, with several more, such as Samsung's BD-UP5000 and Denon's DVD 3800BDCI, on the way. This profile is characterized by dual-decoder picture-in-picture—and at the moment nothing else.

The final profile is often referred to as 2.0, though the requirement is simply BD Live, that is, an Ethernet port that allows internet connectivity for downloading bonus content. There are currently no players that fit this description on the market.

This week, we decided to take a pre-CES look at Blu-ray 1.1. The movies are cool enough—who doesn't like a sci-fi thriller by the guy who made 28 Days Later? And can you even be on Gizmodo if you don't think Milla Jovovich is some kind of supreme being? But the movies' status as the next phase in Blu-ray evolution seems to be an embarrassment for the studios. Rather than champion the 1.1 players and the discs' new capabilities, they celebrate them in the finest of print sizes: For first attempts, the "enhanced viewing" is not bad: In the 1980s, picture-in-picture was a lame concept created to convince wives that the football games could go on in the corner while the soap opera took up 85% of the screen, but that never actually happened. Now picture-in-picture has been reborn as something far more useful, where you can watch a movie while seeing the shots the director saw before special effects came into play, or the sketches that became the sets, or the faces of the commenters as they goof on their faulty stunts.

The Sunshine disc handles PIP with a shiny golden console screen that pops up to contain the standard-def bonus commentary. There aren't many segments, but what is shown, such as walkthroughs of the sets and shooting in zero-gravity, is cool to see juxtaposed with the final film.

Sweet Resident Evil home screen:
Resident Evil shows PIP videos sans fancy frames, but tips the viewer off in a different way. If the shot is on the bottom right, it's actor or director commentary; if the shot appears on the top right, it's a storyboard sketch; and if it's on the bottom left, it's a behind the scenes making-of view.
I will admit, I am not so in love with either title as to spend several more hours combing through each, but functionally it's great, and there are probably many Boyle-heads or fans of "the other" Paul Anderson who would gladly set aside a Saturday for this. I can see how a simulcast of Star Wars with Lucas' ugly mug would make a ton of sense, and all of those bonus Lord of the Rings DVDs might get watched if the making-of footage was embedded into the original high-def films.

The players themselves behaved well. I have recently been on record angry that too many CE products act like PCs, but in both cases the players performed admirably. The PS3's update was easy, and it took the BD Profile 1.1 discs without a hitch. The Panasonic shipped with all the right firmware, and never once rejected a disc. We ran some tests using the HD HQV Benchmark from Silicon Optix as well as the FPD Benchmark Software, and both came out in good shape, though when it came to processing motion, we agreed that the PS3 edged out the Panasonic by a nose.

Everybody knows that precision video testing requires footage of hot Asian women swinging on things: Of course, the Panasonic beat the PS3 in the role of traditional disc player. Sometimes when you hit a button on the PS3 remote, you jump back to the main menu and have to boot up the Blu-ray disc all over again; not so with the Panny. Speaking of remotes, the Panasonic's had a very handy pair of buttons to turn PIP on and off, and to toggle the audio between the two.In the end, we were glad that Blu-ray could now do what we've already seen in Warner HD DVDs such as 300 and the latest Harry Potter. PIP may yet be a wondrous tool. But we're a little puzzled by two things:

1) It's hard to believe that $1,000+ players from Pioneer and Sony Electronics can't do what these were able to do so easily.

2) If this is all possible, why does it take so long to just complete the damn profile and make all players capable of both picture-in-picture interactivity and online connectivity?

If I had to lay money down on one Blu-ray-only player at this minute, I'd have to choose the PS3. The jury is still out on the dual-format players we want to love best, but the early rumblings suggest they may need some work. And any standalone Blu-ray player without an Ethernet jack may be in danger of obsolescence in a few years, if not a matter of months.

We'll personally be looking into all of that... right after CES. In the meantime, stay tuned for big Blu-ray and HD DVD announcements at the show!

This feature would not have been possible without the excellent assistance and admirable photography of Mr. Benny Goldman. Thanks BG!

<![CDATA[ IBM Unleashes Photonic Supercomputer... On a Chip ]]> IBM_Microscope.jpgModern supercomputers are still at least 100 times faster than the crappy laptop you bought a week ago, and electrons are to blame. Today, IBM introduced a way to speed up the action on regular silicon chips by replacing the wiring with pulses of light, a technology called—what else?—silicon photonics. This method works for longer stretches requiring communication between cores, but it doesn't have a major impact in very tight spaces, so copper can still be used. This all may sound familiar, as it's essentially a teeny tiny version of today's fiberoptic networks. Now that you're kicking yourself about that laptop purchase, here's the good news: photonics won't be marketable on chips for another decade. [InfoWorld]

<![CDATA[ Sharp to Step Up Investment in Solar Cell Technology ]]> SharpGI.jpgOfficial reports from Sharp indicate the company is set to invest heavily in thin film silicon solar cells in the coming year. The production shall take place at Sharp's Nara Prefecture plant in Japan. Sharp currently stands as the world's largest solar panel manufacturer, but is not meeting the growing demand.


The new cells will require 1/100th of the silicon traditionally used in typical solar cells. The new cell type standard is in direct response to the limited global abundance of silicon. The market for solar chips continues to grow at around 30% per year, but so do costs for materials. As a result, Sharp has just posted financial losses for the current term. The new cells, it is hoped, shall be a more economically viable, whilst simultaneously being able to meet demand. [Dailytech]
