Researchers from Greece demonstrated a groundbreaking methodology for controlled in-situ reduction of spin-casted graphene oxide (GO) nanometric films on flexible substrates and the subsequent realization of highly conductive and transparent electrodes for flexible organic photovoltaics (OPV). This technique is the first reported to be compatible with temperature sensitive substrates in the sense that it achieves reduction of films on flexible substrates in a single step, in contrast to the approaches utilized so far. Furthermore the featured work provides a new insight in the relevant scientific community considering that it is experimentally clarified that efficient photoreduction of GO can be achieved by exploiting non-thermal processes occurring upon ultrafast laser treatment. This suggests that there is no need for high temperature treatments that potentially destroy the integrity of the graphene lattice as well as the flexibility of the underlying substrate. The in-situ non-thermal photoreduction of spin-coated GO films creates a novel way to produce functional graphene electrodes for a variety of applications in a process that carries substantial promise for potential implementation in organic electronics industry. By employing the optical schemes and translation systems that have already been developed for i ...

MIT researchers find that lubricated, nanotextured surfaces improved performance of condensers in power and desalination plants.Condensers are a crucial part of today’s power generation systems: About 80 percent of all the world’s powerplants use them to turn steam back to water after it comes out of the turbines that turn generators. They are also a key element in desalination plants, a fast-growing contributor to the world’s supply of fresh water.
First awards granted for the NSF Designing Materials to Revolutionize and Engineer our Future (DMREF) program. The National Science Foundation (NSF), in support of the multi-agency, federal Materials Genome Initiative (MGI), has now granted the first awards for the Designing Materials to Revolutionize and Engineer our Future (DMREF) program.The NSF Mathematical and Physical Sciences (MPS) and Engineering (ENG) Directorates invested a total of just over $12 million for 22 grants in support of 14 distinct DMREF projects intended to yield a range of new developments, including new lightweight yet rigid polymers; highly durable, multi-layered materials for aircraft engines and power plants; new data storage technology based on spin electronics; composites for converting heat to electricity; novel designer glasses; membranes that function as well as biological counterparts; new techniques to develop exceptionally hard coatings; and many others.
To craft some of the most complex semiconductors, manufacturers etch pre-defined patterns into wafers, carving out structures layer by layer. The processes can be time-consuming and are executed blindly, leaving few opportunities to monitor the etching or make any necessary adjustments.Now, researchers at the University of Illinois at Urbana-Champaign have developed a technique to watch and control the etching of semiconductors as it is happening, with a height resolution at the scale of nanometers--billionths of a meter.
DNA sequencing is the driving force behind key discoveries in medicine and biology. For instance, the complete sequence of an individual’s genome provides important markers and guidelines for medical diagnostics and healthcare. Up to now, the major roadblock has been the cost and speed of obtaining highly accurate DNA sequences. While numerous advances have been made in the last 10 years, most current high-throughput sequencing instruments depend on optical techniques for the detection of the four building blocks of DNA: A, C, G and T. To further advance the measurement capability, electronic DNA sequencing of an ensemble of DNA templates has also been developed. Recently, it has been shown that DNA can be threaded through protein nanoscale pores under an applied electric current to produce electronic signals at single molecule level. However, because the four nucleotides are very similar in their chemical structures, they cannot easily be distinguished using this technique. Thus, the research and development of a single-molecule electronic DNA sequencing platform is the most active area of investigation and has the potential to produce a hand-held DNA sequencer capable of deciphering the genome for personalized medicine and basic biomedical research.
Nanotech Security Corp., developer of next-generation security and authentication features using nanotechnology based optics, announced that it has achieved a technological breakthrough with the successful metallization of images in a commercial-scale run.

Researchers have learned how to mass produce tiny mechanical devices that could help cell phone users avoid the nuisance of dropped calls and slow downloads. The devices are designed to ease congestion over the airwaves to improve the performance of cell phones and other portable devices."There is not enough radio spectrum to account for everybody's handheld portable device," said Jeffrey Rhoads, an associate professor of mechanical engineering at Purdue University.The overcrowding results in dropped calls, busy signals, degraded call quality and slower downloads. To counter the problem, industry is trying to build systems that operate with more sharply defined channels so that more of them can fit within the available bandwidth.
Microchips are pervasive in today’s high-tech society, playing integral roles in the inner workings of your cell phone to your Keurig coffee machine.A processing technology called CMOS, or complementary metal–oxide–semiconductor, made microchips economically feasible in the 1980s, said Sivasubramanian Somu, a research scientist in Northeastern’s Center for High-rate Nanomanufacturing.A critical element in any microchip is something called an inverter — an electronic component that spits out zeros when you give it ones, and vice versa. “A transistor [the basic element in an inverter] is a simple, extremely fast switch,” Somu explained. “You can turn it on and off by electric signals.”
View Improved Performance Information Needed for Environmental, Health, and Safety Research report What GAO FoundFrom fiscal years 2006 to 2010, the National Science and Technology Council (NSTC) reported more than a doubling of National Nanotechnology Initiative (NNI) member agencies’ funding for nanotechnology environmental, health, and safety (EHS) research––from approximately $38 million to $90 million. Reported EHS research funding also rose as a percentage of total nanotechnology funding over the same period, ending at about 5 percent in 2010. However, GAO identified several reporting problems that raise concerns about the quality of EHS funding data reported. For example, for 18 percent of the 2010 projects GAO reviewed that were reported as EHS research, it was not clear that the projects were primarily directed at EHS risks. In addition, NNI member agencies did not always report funding using comparable data. The absence of detailed guidance on how agencies should report funding for their nanotechnology research has contributed to these problems, as GAO also reported in 2008 and made a related recommendation.In 2010, EHS research at the NNI member agencies GAO reviewed most frequently focused on carbon nanotubes, nanosilver, and nanoscale titanium dioxide. NNI has not prioritized nanomaterials fo ...
Sunscreens, lotions, and cosmetics contain tiny metal nanoparticles that wash down the drain at the end of the day, or are discharged after manufacturing. Those nanoparticles eventually end up in agricultural soil, which is a cause for concern, according to a group of environmental scientists that recently carried out the first major study of soybeans grown in soil contaminated by two manufactured nanomaterials (MNMs).The team was led by scientists at UC Santa Barbara's Bren School of Environmental Science & Management. The team is also affiliated with the UC Center for Environmental Implications of Nanotechnology (CEIN), a $24 million collaboration based at UCLA, with researchers from UCSB, UC Davis, UC Riverside, University of Texas at El Paso, Columbia University, and other national and international partners. The results of the study are published this week in the Proceedings of the National Academy of Sciences.
Thin, conductive films are useful in displays and solar cells. A new solution-based chemistry developed at Brown University for making indium tin oxide films could allow engineers to employ a much simpler and cheaper manufacturing process.PROVIDENCE, R.I. [Brown University] — In a touch-screen display or a solar panel, any conductive overlay had better be clear. Engineers employ transparent thin films of indium tin oxide (ITO) for the job, but a high-tech material’s properties are only half its resume. They must also be as cheap and easy to manufacture as possible. In a new study, researchers from Brown University and ATMI Inc. report the best-ever transparency and conductivity performance for an ITO made using a chemical solution, which is potentially the facile, low-cost method manufacturers want.“Our technology is already at the performance level for application in resistive touch screens,” said Jonghun Lee, a Brown chemistry graduate student and lead author of the paper posted online Aug. 1 by the Journal of the American Chemical Society.The group made conductive ITO films 146 billionths of a meter thick that allowed 93 percent of light to pass through, a transparency comparable to the glass plates they were deposited on. The team also made their films on top of bendable polyimide, showing that it cou ...
The U.S. Forest Service Forest Products Laboratory recently opened a $1.7 million production facility for renewable, forest-based nanomaterials. This facility is the first of its kind in the United States and one that positions the laboratory as the country’s leading producer of these materials, also called nanocellulose.
Nanocellulose is simply wood fiber broken down to the nanoscale. For perspective, a nanometer is roughly one-millionth the thickness of an American dime. Materials at this minute scale have unique properties; nanocellulose-based materials can be stronger than Kevlar fiber and provide high strength properties with low weight. These attributes have attracted the interest of the Department of Defense for use in lightweight armor and ballistic glass. Companies in the automotive, aerospace, electronics, consumer products, and medical device industries also see massive potential for these innovative materials.
Researchers from North Carolina State University have developed highly conductive and elastic conductors made from silver nanoscale wires (nanowires). These elastic conductors can be used to develop stretchable electronic devices.Stretchable circuitry would be able to do many things that its rigid counterpart cannot. For example, an electronic “skin” could help robots pick up delicate objects without breaking them, and stretchable displays and antennas could make cell phones and other electronic devices stretch and compress without affecting their performance. However, the first step toward making such applications possible is to produce conductors that are elastic and able to effectively and reliably transmit electric signals regardless of whether they are deformed.
Fifth NSI will accelerate the development of nano-enabled sensors and nanomaterial sensingThe Nanotechnology Signature Initiative (NSI) Nanotechnology for Sensors and Sensors for Nanotechnology: Improving and Protecting Health, Safety, and the Environment is the fifth NSI to be launched by agencies of the National Nanotechnology Initiative (NNI). The NNI agencies recognize the considerable potential for nanotechnology to open the door to the development of inexpensive, portable devices that can rapidly detect, identify, and quantify biological and chemical substances. As such, nanosensors are expected to lead to revolutionary applications, including early disease detection that can result in faster treatments and better outcomes, as well as the early and accurate detection of environmental pollutants, contaminants, and even biological or chemical weapons. Due to the diverse nature of these potential applications, nanosensors are expected to impact multiple sectors of the economy, including the healthcare, pharmaceutical, agricultural, food, environmental, consumer products, and defense sectors.
Graphene, a one-atom-thick layer of graphitic carbon, has attracted a great deal of attention for its potential use as a transistor that could make consumer electronic devices faster and smaller. But the material's unique properties, and the shrinking scale of electronics, also make graphene difficult to fabricate on a large scale. The production of high-performance graphene using conventional fabrication techniques often leads to damage to the graphene lattice's shape and performance, resulting in problems that include parasitic capacitance and serial resistance.
In the last two decades, the number of deaths from colorectal cancer has steadily declined, according to the American Cancer Society. While some of the decrease can be attributed to better treatment practices, early detection is another primary factor. Nonetheless, colorectal cancer is still the second leading cause of death among men and women in the U.S., and is expected to be responsible for more than 50,000 deaths in 2012.

Overall, PCAST concluded that the NNI remains a successful cooperative venture that is supporting high-quality research, facilitating the trans ...
Solvay, Holst Centre and several other partners demonstrate flexible 69cm2 Organic LED (OLED) lighting tiles with an efficiency of 30lm/Watt.Chemical group Solvay and Holst Centre have demonstrated high efficiency flexible Organic Light Emitting Diodes (OLED) lighting tiles with a surface area of 69cm2. These large-area demonstrators contain several layers deposited by solution processing at Holst Centre and additional layers applied by conventional vacuum deposition at Solvay.OLEDs are a new lighting technology enabling flat diffuse lighting sources, and are complementary to inorganic LEDs, which are by nature well suited as spotlights. Current OLED devices are made at pilot scale by depositing many layers on glass by vacuum process. Solvay and Holst Centre were able to deposit several layers of the OLED by solution processing, which brings the use of printing technologies to produce OLEDs closer.Use of printing technologies on flexible substrates will enable large scale manufacturing of OLEDs for general lighting applications, and will bring some additional features: thin, flexible, and potentially transparent light sources that could be integrated in ceiling, walls, windows…The highly efficient flexible OLED stack was designed and optimized at Solvay. It is based almost entirely on organic functional materials develope ...
The first draft guideline, “Draft Guidance for Industry, Considering Whether an FDA-Regulated Product Involves the Application of Nanotechnology”, was published in the Federal Register in June, 2011. The FDA is still reviewing and receiving comments on this document from the public.In April 2012 the FDA is issuing two new draft guidelines for manufacturers of food substances and cosmetics, which are also open for public comment.FDA Commissioner Margaret A. Hamburg, M.D., says the guidelines provide a starting point for the nanotechnology discussion. “Our goal is to regulate these products using the best possible science,” Hamburg says. “Understanding nanotechnology remains a top priority within the agency’s regulatory science initiative and, in doing so, we will be prepared to usher science, public health, and FDA into a new, more innovative era.”FDA is working with the White House, the National Nanotechnology Initiative, other U.S. government agencies, and international regulators to focus on generating data and coordinating policy approaches to ensure the safety and effectiveness of products using nanomaterials.
