Graphene foam detects explosives, emissions better than today's gas sensors

(PhysOrg.com) -- A new study from Rensselaer Polytechnic Institute demonstrates how graphene foam can outperform leading commercial gas sensors in detecting potentially dangerous and explosive chemicals. The discovery opens the door for a new generation of gas sensors to be used by bomb squads, law enforcement officials, defense organizations, and in various industrial settings.

The new sensor successfully and repeatedly measured ammonia (NH3) and nitrogen dioxide (NO2) at concentrations as small as 20 parts-per-million. Made from continuous graphene nanosheets that grow into a foam-like structure about the size of a postage stamp and thickness of felt, the sensor is flexible, rugged, and finally overcomes the shortcomings that have prevented nanostructure-based gas detectors from reaching the marketplace.

Results of the study were published today in the journal Scientific Reports, published by Nature Publishing Group. See the paper, titled “ High Sensitivity Gas Detection Using a Macroscopic Three-Dimensional Graphene Foam Network.”

“We are very excited about this new discovery, which we think could lead to new commercial gas sensors,” said Rensselaer Engineering Professor Nikhil Koratkar, who co-led the study along with Professor Hui-Ming Cheng at the Shenyang National Laboratory for Materials Science at the Chinese Academy of Sciences. “So far, the sensors have shown to be significantly more sensitive at detecting ammonia and nitrogen dioxide at room temperature than the commercial gas detectors on the market today.”

Over the past decade researchers have shown that individual nanostructures are extremely sensitive to chemicals and different gases. To build and operate a device using an individual nanostructure for gas detection, however, has proven to be far too complex, expensive, and unreliable to be commercially viable, Koratkar said. Such an endeavor would involve creating and manipulating the position of the individual nanostructure, locating it using microscopy, using lithography to apply gold contacts, followed by other slow, costly steps. Embedded within a handheld device, such a single nanostructure can be easily damaged and rendered inoperable. Additionally, it can be challenging to “clean” the detected gas from the single nanostructure.

The new postage stamp-sized structure developed by Koratkar has all of the same attractive properties as an individual nanostructure, but is much easier to work with because of its large, macroscale size. Koratkar’s collaborators at the Chinese Academy of Sciences grew graphene on a structure of nickel foam. After removing the nickel foam, what’s left is a large, free-standing network of foam-like graphene. Essentially a single layer of the graphite found commonly in our pencils or the charcoal we burn on our barbeques, graphene is an atom-thick sheet of carbon atoms arranged like a nanoscale chicken-wire fence. The walls of the foam-like graphene sensor are comprised of continuous graphene sheets without any physical breaks or interfaces between the sheets.

Koartkar and his students developed the idea to use this graphene foam structure as a gas detector. As a result of exposing the graphene foam to air contaminated with trace amounts of ammonia or nitrogen dioxide, the researchers found that the gas particles stuck, or adsorbed, to the foam’s surface. This change in surface chemistry has a distinct impact upon the electrical resistance of the graphene. Measuring this change in resistance is the mechanism by which the sensor can detect different gases.

Additionally, the graphene foam gas detector is very convenient to clean. By applying a ~100 milliampere current through the graphene structure, Koratkar’s team was able to heat the graphene foam enough to unattach, or desorb, all of the adsorbed gas particles. This cleaning mechanism has no impact on the graphene foam’s ability to detect gases, which means the detection process is fully reversible and a device based on this new technology would be low power—no need for external heaters to clean the foam—and reusable.

Koratkar chose ammonia as a test gas to demonstrate the proof-of-concept for this new detector. Ammonium nitrate is present in many explosives and is known to gradually decompose and release trace amounts of ammonia. As a result, ammonia detectors are often used to test for the presence of an explosive. A toxic gas, ammonia also is used in a variety of industrial and medical processes, for which detectors are necessary to monitor for leaks.

Results of the study show the new graphene foam structure detected ammonia at 1,000 parts-per-million in 5 to 10 minutes at room temperature and atmospheric pressure. The accompanying change in the graphene’s electrical resistance was about 30 percent. This compared favorably to commercially available conducting polymer sensors, which undergo a 30 percent resistance change in 5 to 10 minutes when exposed to 10,000 parts-per-million of ammonia. In the same time frame and with the same change in resistance, the graphene foam detector was 10 times as sensitive. The graphene foam detector’s sensitivity is effective down to 20 parts-per-million, much lower than the commercially available devices. Additionally, many of the commercially available devices require high power consumption since they provide adequate sensitivity only at high temperatures, whereas the graphene foam detector operates at room temperature.

Koratkar’s team used nitrogen dioxide as the second test gas. Different explosives including nitrocellulose gradually degrade, and are known to produce nitrogen dioxide gas as a byproduct. As a result, nitrogen dioxide also is used as a marker when testing for explosives. Additionally, nitrogen dioxide is a common pollutant found in combustion and auto emissions. Many different environmental monitoring systems feature real-time nitrogen dioxide detection.

The new graphene foam sensor detected nitrogen dioxide at 100 parts-per-million by a 10 percent resistance change in 5 to 10 minutes at room temperature and atmospheric pressure. It showed to be 10 times more sensitive than commercial conducting polymer sensors, which typically detect nitrogen dioxide at 1,000 part-per-million in the same time and with the same resistance chance at room temperature. Other nitrogen dioxide detectors available today require high power consumption and high temperatures to provide adequate sensitivity. The graphene foam sensor can detect nitrogen dioxide down to 20 parts-per-million at room temperature.

“We see this as the first practical nanostructure-based gas detector that’s viable for commercialization,” said Koratkar, a professor in the Department of Mechanical, Aerospace, and Nuclear Engineering at Rensselaer. “Our results show the graphene foam is able to detect ammonia and nitrogen dioxide at a concentration that is an order of magnitude lower than commercial gas detectors on the market today.”

The graphene foam can be engineered to detect many different gases beyond ammonia and nitrogen dioxide, he said.

Studies have shown the electrical conductivity of an individual nanotube, nanowire, or graphene sheet is acutely sensitive to gas adsorbtion. But the small size of individual nanostructures made it costly and challenging to develop into a device, plus the structures are delicate and often don’t yield consistent results.

The new graphene foam gas sensor overcomes these challenges. It is easy to handle and manipulate because of its large, macroscale size. The sensor also is flexible, rugged, and robust enough to handle wear and tear inside of a device. Plus it is fully reversible, and the results it provides are consistent and repeatable. Most important, the graphene foam is highly sensitive, thanks to its 3-D, porous structure that allows gases to easily adsorb to its huge surface area. Despite its large size, the graphene foam structure essentially functions as a single nanostructure. There are no breaks in the graphene network, which means there are no interfaces to overcome, and electrons flow freely with little resistance. This adds to the foam’s sensitivity to gases.

“In a sense we have overcome the Achilles’ heel of nanotechnology for chemical sensing,” Koratkar said. “A single nanostructure works great, but doesn’t mean much when applied in a real device in the real world. When you try to scale it up to macroscale proportions, the interfaces defeats what you’re trying to accomplish, as the nanostructure’s properties are dominated by interfaces. Now we’re able to scale up graphene in a way that the interfaces are not present. This allows us to take advantage of the intrinsic properties of the nanostructure, yet work with a macroscopic structure that gives us repeatability, reliability, and robustness, but shows similar sensitivity to gas adsorbtion as a single nanostructure.”

I have been following this company for some time Donpat. I don't know much about you other than you love "penny plays". Why are you so hot on ANH now? As far as I can remember they have been promising many of these things time and time again. I personally don't like patent type models because they don't actually own anything of substance. Patents come and go and can be cancelled or voided in an instant.

With that being said I have always thought there were great minds involved with this company along with some great innovations.

I was IN the patent biz for 35 years and can't get it out of my system! One of these days!!!

I like nanotech's prospects be it in materials strengthening or medicine delivery, diagnosis and treatment - and ANI is involved in all of those.

So I follow it, having bought in over the years - averaging out at ~ 90¢.

It's a pastime!

I leave my real money with pros!

I'm now in the position of wanting/needing to be vindicated.

We shall see, soon, I hope!

Apple’s 2012 i HDTV- Filling In The Blanks

[My note: RAMAN rules!]

July 5th, 2011 ·

4 Comments · 3D HDTV, CNT FED, Connected TVs, LCD Flat Panel, LED LCD Flat Panels, News




A number of websites have leaked information about an upcoming Apple iHDTV. HD Guru examined the bits and pieces, and together with information on new technologies from other HDTV tech stories and the recent SID show, we’ve put together a picture of what we expect from Apple as the next HDTV maker.


Software

With Apple’s long tradition breaking new ground, we anticipate the Apple iHDTV to launch with significant HDTV improvements.

It’s a given the iHDTV will have the Apple iOS found in the Apple TV box, iPhone and iPad. In addition, it’s a safe bet to assume Apple’s upcoming iCloud system will be included as well, with movies and TV programs.

Hardware

There’s a long relationship between Samsung and Apple for components. This, coupled with Samsung’s LCD manufacturing partnership with Sony and other TV makers, other websites are predicting Samsung as the panel supplier and we concur.

It’s possible, though, that this Apple/Samsung TV will feature a next-generation display technology that will outperform today’s cutting-edge LED LCDs.

According to a number of reports out of Asia including the etnews, late last year Samsung began the conversion of one of its plasma plants to produce Carbon Nano Tube Field Emitter Display (CNT-FED) Back Light Units. A CNT-FED would replace LEDs to create the light for LCDs. One of the main advantages of this technology is the ability to provide very local dimming. Single-pixel local dimming is possible, if the design/cost calls for it.. The result is totally black pixels next to brightly lit pixels (insanely high legitimate contrast ratios), plus lower power consumption.

Here is how they work as explained by Jim Kim’s Displayblog.com website in 2008. “Field emission technology is a variation on how CRTs and plasmas work by using electrons to excite phosphors on a screen. In Samsung's example, the control is fine tuned by the use of carbon nanotubes and a unique structure. The carbon nanotubes are used as emissive tips. Nanotubes are deposited on a flat surface and is treated with an elastomer. The elastomer allows the exposed nanotubes to stand up, which then can be used as emissive tips. A TFT-like grid is layered above the nanotubes to control the movement of electrons to excite the red, green and blue phosphors.”

According to ET news, the first CNT-FED backlight units will be 46-Inch screen size, an ideal size for Apple and the size of Samsung’s current best selling model.

Further improving performance would be the use of Samsung’s new VA 1 (Vertical Alignment) display with its wider viewing angle and faster refresh ( link).

We expect this iHDTV to launch by end of Q1 2012. The price? Well, it’s Apple, so probably not cheap, but not too expensive either.

Switched On: Keeping the 'app' out of Apple's TV

By Ross Rubin posted Dec 4th 2011 8:24PM

Each week Ross Rubin contributes Switched On, a column about consumer technology.



Rumors continue to heat up that Apple will enter the television market next year, stepping up its Apple TV "hobby" into a greater revenue-generating vocation. The company would clearly like to repeat the kind of rousing success it has seen in smartphones. There, it entered a market at least as crowded and competitive as that for televisions whereas most of its Windows rivals have barely been able to eke out a few models with nominal share..

Indeed, the challenge is not as much about competition as commoditization. At first glance, this would be a curious time for Apple to enter the TV space. The HD and flat-panel transitions on which premium manufacturer brands and retailers once feasted has long passed. "Flat-panel TV" and "HDTV" are now just "TV." And prices for smaller sets are settling into a range familiar to those who remember what they cost back in the heyday of CRTs.

What's different, though, is that the state of the smart TV market looks strikingly like the smartphone market did before Apple's entrance. The market essentially has "feature TVs" that present a few popular canned services (YouTube, Netflix, Hulu, Pandora, etc.) and "smart TVs" that are a fractured mixture of homegrown offerings (from companies such as Panasonic, Samsung, LG and Toshiba) and an experience-challenged licensed OS (Android from Sony and Vizio).
The company has clung to the idea of TV as a passive experience.This doesn't mean, though, that Apple would necessarily see its television as a way to extend the iOS developer base any more than it has opened up the Mac to such apps, at least at launch. Switched On has previously discussed the challenges that TV-based apps face. If putting such apps on a TV was Apple's plan, why wouldn't it get it started via support on today's Apple TV box? Even if Apple exceeds its wildest dreams for success with an Apple-branded television, there will be a much, much larger base of Apple TV-accessible HDTVs from other brands available for the foreseeable future.

The company has clung to the idea of TV as a passive experience. Indeed, enabling iPhone-like apps on a TV would likely require some Magic Trackpad-like remote, which is not, in the words of Steve Jobs, "the simplest user interface you could imagine." So, what is Apple's opportunity then? There are at least two paths it can take to creating a compelling, differentiated TV experience. They are:

Aggregation: Switched On has also previously discussed the promise of an iTunes-based subscription alternative to cable. Alas, it has been difficult for any company to coax content owners to abandon their lucrative cable compensation deals. And while Apple may have the cash to do so, it doesn't seem like the sort of spendy deal in Apple's character. Of course, user interface and input would play a huge role. Siri or some Siri-like agent could pluck shows from across services such as Netflix and Hulu if Apple can't pull together an integrated subscription service of its own and repeat the disruption it originally made with the iTunes Music Store..

Integration: The cliche "if you can't beat 'em, join 'em" hasn't worked in the world of broadband television. As difficult as it has been to assemble a competitive show lineup to facilities-based incumbent TV service providers, it hasn't been much easier to integrate the richness of that platform. Most have tried either the kludgey (IR emitters used by early TiVo boxes and the Logitech Revue) to the obscure (CableCARD, used by modern TiV0 boxes, which is hardly universal in the U.S. much lsess Apple's other global markets).

If Apple were to find some way to remix the content that most consumers were already paying for, it would have a huge advantage versus other TV makers. But Comcast and TimeWarner have been slow to provide the keys to the content kingdom to even current high-volume TV companies such as Samsung and Sony. Historically, Apple has been one ring away from Netflix on cable company dartboards, although many of them can't seem to rush enough video to the iPad today. Perhaps Apple could use the iPad as a leverage point. After all, a simple cable or AirPlay support is all that separates its display form a television today.

Over the next few years, Internet connectivity will become a common feature in TV sets. It is already becoming so in 40-inch+ models. Apple seems to be under no pressure to enter the market. With its current Apple TV,it can send a wide range video content up to a television with ease, and future versions of Wi-Fi will easily support the ability to do so in the best quality available. It's almost certain that an Apple-branded television would (and would have to) differentiate on user experience well beyond an engagement level that Apple TV delivers today. Beyond that, optimizing the selection and presentation of the content consumers want is the critical task for any company that would seek to reinvent the TV.
