Researchers at the University of California at Irvine (UCI) have accidentally – yes, accidentally – discovered a nanowire-based technology that could lead to batteries that can be charged hundreds of thousands of times.
Mya Le Thai, a PhD candidate at the university, explained in a paper published this week that she and her colleagues used nanowires, a material that is several thousand times thinner than a human hair, extremely conductive and has a surface area large enough to support the storage and transfer of electrons.
Nanowires are extremely fragile and don’t usually hold up well to repeated discharging and recharging, or cycling. They expand and grow brittle in a typical lithium-ion battery, but Le Thai’s team fixed this by coating a gold nanowire in a manganese dioxide shell and then placing it in a Plexiglas-like gel to improve its reliability. All by accident.
The breakthrough could lead to laptop, smartphone and tablet batteries that last forever.
Reginald Penner, chairman of UCI’s chemistry department, said: “Mya was playing around and she coated this whole thing with a very thin gel layer and started to cycle it.
“She discovered that just by using this gel she could cycle it hundreds of thousands of times without losing any capacity. That was crazy, because these things typically die in dramatic fashion after 5,000 or 6,000 or 7,000 cycles at most.”
The battery-like structure was tested more than 200,000 times over a three-month span, and the researchers reported no loss of capacity or power.
“The coated electrode holds its shape much better, making it a more reliable option,” Thai said. “This research proves that a nanowire-based battery electrode can have a long lifetime and that we can make these kinds of batteries a reality.”
The breakthrough also paves the way for commercial batteries that could last a lifetime in appliances, cars and spacecraft.
British fuel-cell maker Intelligent Energy Holdings announced earlier this year that it is working on a smartphone battery that will need to be charged only once a week.

Will Intel Assist Apple?
Apple is apparently having problems getting its partners to make 3-D transistors that go.
Drexel Hamilton’s chip analyst Rick Whittington [no really] made a comment that Intel might be getting ready to bail Apple out while he was having a chat about Micron. In passing, Whittington noted problems had by Taiwan Semiconductor and Samsung Electronics trying to produce 3-D transistors in any useful yield.
He noted that Intel has mastered 3-D transistors, and said that it would be very good for Intel if neither Samsung or TSM can do FinFET this next year; puts them in line to supply Apple’s internal foundry needs.
However he admitted that it was more that TSM/Samsung would operate FinFET under very low yield output and keep capacity tight.
Of course if Jobs’ Mob don’t want that they can always rush into the loving arms of Chipzilla – again. As happened with Saphire glass Apple has shown that it can dump a partner quickly if it does not move fast enough.
Are Transparent Semiconductors Next?

Scientist have emerged from their smoke filled labs with transparent thin-film organic semiconductors that could become the foundation for cheap, high-performance displays. Two university research teams have worked together to produce the world’s fastest thin-film organic transistors, proving that this experimental technology has the potential to achieve the performance needed for high-resolution television screens and similar electronic devices.
According to the latest issue of Nature Communications, engineers from the University of Nebraska-Lincoln (UNL) and Stanford University show how they created thin-film organic transistors that could operate more than five times faster than previous examples of this experimental technology.
Research teams led by Zhenan Bao, professor of chemical engineering at Stanford, and Jinsong Huang, assistant professor of mechanical and materials engineering at UNL used their new process to make organic thin-film transistors with electronic characteristics comparable to those found in expensive, curved-screen television displays based on a form of silicon technology.
At the moment the high tech method is to drop a special solution, containing carbon-rich molecules and a complementary plastic, onto a spinning platter made of glass. The spinning action deposits a thin coating of the materials over the platter. The boffins worked out that if they spun the platter faster and coated a tiny portion of the spinning surface, equivalent to the size of a postage stamp they could put a denser concentration of the organic molecules into a more regular alignment. The result was a great improvement in carrier mobility, which measures how quickly electrical charges travel through the transistor.
Intel’s Bay Trail M Is On The Way
Intel launched its Bay Trail-M ultra low voltage processors for netbooks and mobile devices over the weekend. According to CPU World the new mobile CPUs, branded this time as Celeron and Pentium, can manage twice the CPU performance, and up to three times faster graphics.
They do all that while using the same amount of juice as their “Cedar Trail” predecessors. Most chips have higher clock speeds than N2805, N2810 and N2910 SKUs and come with Burst Performance technology. They can operate at a higher maximum operating temperature which makes them easier to cool. Finally, in addition to 4 N28xx/N29xx Celerons Intel also released Pentium N2920.
Then there are new dual-core Bay Trail-M microprocessors like the Celeron N2806, N2815 and N2820 which can operate at frequencies from 1.6 GHz to 2.13 GHz, when going downhill had the wind is behind them. They also have the maximum burst speed ranging from 2 GHz to 2.39 GHz. The processors come with 1 MB L2 cache, Ivy Bridge graphics clocked at 311 MHz and up to 756 MHz, and support for DDR3L-1066 memory. The N2806 has 4.5 Watt TDP while the N2815 and N2820 have 7.5 Watt TDP. All of the Celeron N28xx processors are priced at $132.
Two new quad-core microprocessors are Celeron N2920 and Pentium N3520. The CPUs have 2 MB L2 cache, and run at 1.86 GHz and 2.17 GHz respectively, with burst frequencies reaching 2 GHz and 2.42 GHz. Both parts integrate Ivy Bridge graphics, that can be clocked as high as 854 MHz. The Celeron can deal with DDR3L-1066 memory, and the Pentium supports 1333 MHz memory data rate. They fit into 7.5 Watt power envelope. The official prices of Celeron N2920 and Pentium N3520 are $132 and $180.
Does Wall Street Like Intel’s Mobile Plan?
Comments Off on Does Wall Street Like Intel’s Mobile Plan?
In recent months Intel’s new CEO Brian Krzanich and President Renee James made several interesting statements, signalling to Wall Street that the chipmaker gets it – it has to do more in mobile.
With smartphone shipments expected to hit one billion per year as early as next year, Intel’s newfound love of mobile chips is hardly surprising. In recent months Intel told the world that it’s now treating Atom just like Core, which means Atom will no longer look like an unwanted stepchild. On the face of it this is good news for shareholders and investors, but scratch the surface it doesn’t look too encouraging.
As a result, most analysts expect Intel to post lacklustre results on Tuesday, which is hardly surprising given the state of the PC market, which is still the bulk of Intel’s core business. Analysts expect revenue of $13.47 billion, 0.1 percent higher year-on-year, but earnings per share are estimated at $0.53, or 8.6 percent down over last year. But negative EPS forecasts aren’t the biggest problem facing Intel. Most analysts agree that 2014 won’t be much better, but there are some factors that indicate even these bleak forecasts might be too optimistic.
The first Bay Trail products are starting to appear and initial performance reports are encouraging, but they are just that – encouraging rather than groundbreaking. Benchmarks seem to indicate that Bay Trail-T tablets end up marginally slower than Qualcomm 800 and Tegra 4 based devices, which are a bit older, too. With prices ranging from $32 to $37, the first batch of Bay Trail chips also cost a bit more than their ARM competitors, but a direct comparison is not possible as ARM players don’t disclose the unit prices of their chips.
Furthermore Intel still lacks integrated LTE support, which means Bay Trail isn’t going to score big phone design wins. Intel hopes to roll out its first LTE enabled products next year, but there’s still some ambiguity. For example, Intel discrete modems are still built on TSMC silicon and it could be a couple of years before they end up on the die of an Intel SoC built in an Intel fab. While Intel could roll out the first two-chip solution next year, it’s highly unlikely that it will have a proper integrated solution before 2015.
This is a bit of a problem for more reasons than one. Many analysts don’t dig deep enough, some of these technical issues go under the radar – so they stick to Intel’s promise of LTE in 2014. Quark is also being overhyped, although it won’t generate any significant revenue over the next few years. Many analysts also believe x86 support is still a big deal, and to some extent it is, but the relevance of x86 is often exaggerated and it is diminishing as we speak. That is why Intel is talking up hybrids, or 2-in-1s – because legacy x86 support is a lot more important for hybrids than regular tablets. In smartphones, x86 support is as useless as a Facebook share button on a porn site.
However, this is where it gets interesting, because Intel is also promising $99 Bay Trail tablets. Back at IDF, Krzanich said Intel’s new tablet platform would “go below $100 by Q4 2013,” giving the impression that Intel can do dirt cheap tablets as well. We are not sure that it can, not unless it subsidizes them with heaps of cash, and we all know how well that went with Ultrabooks.
As for phones, Intel is still dead in the water and this won’t change anytime soon. Apple is quite happy designing its own custom chips and having them built by the lowest bidder. Samsung is going for off-the-shelf IP and manufacturing its Exynos 5 chips in 28nm, and it will hit 20nm soon. Qualcomm dominates the market and Intel can’t erode its lead over the next couple of product cycles. Even if Intel comes up with competitive smartphone chips in a year or two, who will they be for? Apple won’t buy them, neither will Samsung. This would leave Intel in an awkward position of fighting over scraps with heavy hitters like Qualcomm and a range of smaller ARM players like Nvidia and MediaTek.
This is hardly a viable long-term mobile strategy. Intel is basically doing the only thing it can – and doing the only thing that can be done and calling it a strategy doesn’t really make for much of a strategy.
Intel Goes AI
Intel has written a check for the Spanish artificial intelligence technology startup Indisys.
The outfit focuses on natural language recognition and the deal is worth $26 million. It follows Intel’s recent acquisition of Omek, an Israeli startup with specialties in gesture-based interfaces. Indisys employees have joined Intel already. Apparently the deal was signed on May 31 and the deal has been completed.
Intel would not confirm how they are using the tech: “Indisys has a deep background in computational linguistics, artificial intelligence, cognitive science, and machine learning. We are not disclosing any details about how Intel might use the Indisys technologies at this time.”
HP Goes All-In On Tablets
Hewlett-Packard garnered attention at Mobile World Congress show with its new Slate 7-inch tablet and then the sale of webOS assets, but the company is looking to put past distractions behind and will release more tablets in the future, the company said.
“You can expect going forward [to release] a family of products,” said Shane Wall, chief technology officer at Hewlett-Packard’s mobility group, in an interview at MWC. The mobility trade show is being held in Barcelona from Feb. 25 to 28.
The 7-inch tablet attracted a small crowd at the HP booth, with people lining up to photograph or use the device. The company effectively took a dive into the low-cost tablet and tried to differentiate its tablet by a lower price, and also features like a micro-SD card slot for expandable storage and dual-cameras. Google’s $199 Nexus 7 is priced higher and has a quad-core processor, a higher-resolution screen and Android 4.2, but HP believes it will sell a lot of the tablets at the $169 price.
“We’re obviously late,” Wall said. “We wanted to start and see how aggressive we can be on the low end.”
The Slate 7 also signifies HP’s re-entry into the consumer tablet market after a disastrous stint with the webOS mobile operating system, which it got with the acquisition of Palm in 2010 for $1.2 billion. The first webOS tablet, the TouchPad, was launched in 2011, but later discontinued along with webOS smartphones. Since then HP has released enterprise tablets such as ElitePad 900 with Windows 8, and now the company has adopted Android for consumer tablets.
Intel Wins Patent Case
Intel has had a previous decision upheld by the US International Trade Commission (ITC), which decided it did not infringe several X2Y chip manufacturing patents.
X2Y had claimed that Intel’s chip manufacturing technology infringed five of its patents and requested an injunction to stop the chips from entering the US. Previously Judge David Shaw ruled that Intel did not infringe X2Y’s patents, a decision that has been upheld by the ITC, which said it will “terminate the investigation with a finding of no violation”.
X2Y’s patents relate to the shielding of electromagnetic interference that is a significant problem in electronics manufacture. The firm has sold licenses to other chipmakers including Samsung, however Intel decided to develop its own techniques, which are now deemed not to infringe X2Y’s patents.

While Intel had the most to lose, X2Y also went after Apple and HP, two of Intel’s highest profile customers. Intel even argued that an injunction on its chips would hurt American jobs.
Not only did X2Y lose its patent battle with Intel, but two of its patents were ruled invalid. The company had filed two civil lawsuits that were put on hold pending the ITC’s decision, but given the ITC action it will be surprising if the firm continues in its legal campaign against Intel.
