Mobilizing women scientists in Nano-Science to participate at EU programmes
Mobilizing stakeholders in favour of gender equality in scientific research
Stimulating and facilitating a science-society dialogue
"...acting as ambassadors for women in nano-science"
The Specific Support Action (SSA) “Strengthening the Role of Women Scientists in Nano-Science” = WomenInNano is funded by the 6th Framework programme of the European
Commission in “Science and Society”/ "Women and Science"
It brings
together 11 partners from 9 European countries - Germany, Romania,
Sweden, Spain, Slovenia, United Kingdom, Bulgaria, Italy and France –
under the coordination of the Leibniz Institute for Solid State and Materials Research IFW Dresden, Germany. The basic idea of the project is to allow high-level women
scientists working in Nano-science to act as Ambassadors for Women and
Science in order to raise awareness of gender issues in science (more
specific, in Nano-Science) and to provide ‘role models’ for girls and
women, with a view to encouraging them to consider studies and pursue
careers in scientific fields. The project will empower and enlarge the
women scientists group working in Nano-Science and increase its
visibility in the international scientific community. WomenInNano
proposes a series of activities, which will create and stimulate
structural links at national, trans-national, regional and
trans-regional level between scientists (female and male), policy makers
and society at large.
Berkeley, CA – For millions of years, green plants have employed photosynthesis to capture energy from sunlight and convert it into electrochemical energy. A goal of scientists has been to develop an artificial version of photosynthesis that can be used to produce liquid fuels from carbon dioxide and water. Researchers with the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have now taken a critical step towards this goal with the discovery that nano-sized crystals of cobalt oxide can effectively carry out the critical photosynthetic reaction of splitting water molecules.
Cobalt oxide nanocrystals can effectively be used to
split water molecules, one of the half reactions critical to an artifical photosynthesis system for producing liquid fuels from sunlight.
An aqueous solution contains silica particles that have been embedded with photooxidizing cobalt oxide nanocrystals plus a sensitizer to allow the water-splitting reaction to be driven by visible light. When laser light hits the solution it turns blue as the sensitizer absorbs light. Bubbles soon begin to form as oxygen gas is released from the spilt water molecules

A blazing coating lets microscopic carbon nanotubes generate electricity
Engineers at MIT have devised what they call a new way of producing electricity. By coating a microscopic carbon nanotube with
a layer of fuel and igniting one end with a spark or laser, they're able to send a wave of heat shooting through the nanotube's interior.
This
thermal wave pushes electrons in its path, generating a significant electric current. Prototypes already have energy density 100 times
greater than lithium-ion batteries, and they can be stored indefinitely without leaking charge. The researchers are now investigating optimal
fuels and, to make the system reusable, will have to invent a way to automatically apply a fresh layer of fuel after the first burns away.
How It Works:
1. Heat the Tube. One end of a microscopic carbon nanotube, coated with reactive fuel, is ignited by a laser.
2. Herd the Particles. A wave of heat races through the inside of the tube, pushing electrons toward the other end.
3. Harvest the Energy. The movement of the electrons forms an electric current.

MADE IN IBM LABS: Computer memory that combines the high performance and reliability of flash with the low cost and high capacity of the hard disk drive could be closer than you think, thanks to a team of IBM scientists.
In two papers published recently in the journal Science, IBM Fellow Stuart Parkin and colleagues at the IBM Almaden Research Center in San Jose describe both the fundamentals of a technology dubbed "racetrack" as well as a milestone in that technology. This milestone could lead to electronic devices capable of storing far more data in the same amount of space than is possible today, with lightning-fast boot times, far lower cost and unprecedented stability and durability.
Within the next ten years, racetrack memory, so named because the data "races" around the wire "track," could lead to solid state electronic devices -- with no moving parts, and therefore more durable -- capable of holding far more data in the same amount of space than is possible today. For example, this technology could enable a handheld device such as an mp3 player to store around 500,000 songs or around 3,500 movies -- 100 times more than is possible today -- with far lower cost and power consumption. The devices would not only store vastly more information in the same space, but also require much less power and generate much less heat, and be practically unbreakable: the result, massive amounts of personal storage that could run on a single battery for weeks at a time and last for decades.
The commercial availability of racetrack stands to take microelectronics into the third dimension, exceeding the two-dimensional limits of Moore's Law. And IBM is no stranger to creating entirely new markets that spring from exploratory research such as this. Just a few of the many game-changers invented at IBM Research include the memory chip, the hard disk drive and the relational database.

A transparent coating that isn't just impermeable to water but actually makes it bounce off a surface has a number of potentially interesting applications. It could prevent corrosion, protect electronics and antiquities, or provide a new, more efficient surface to collect pure water. Modeled from Nature, the Brinker group used sol-gel chemistry to make a patent-applied-for, simple-to-prepare coating solution that, upon simple drying, develops a nanoscopically rough silicon dioxide surface decorated with hydrophobic (water-hating) ligands.

Unlike most biological membranes, polymeric, nanometer-thin membranes are very stable and can withstand considerable pressure. This is an essential requirements for separation processes such as in water purification and desalination. Because their mechanical stability can be combined with flexibility and chemical functionality, polymer nanomembranes are also intensely researchers as materials for actuators and microsensors. They have also entered the biomedical field as artificial nacre and as a novel material used in surgery. Crosslinking of a spin-coated precursor solution, a common fabrication technique, reduces the interactions between the polymer chains and the environment and thus impairs the sensitivity and flexibility of the films. Researchers in Germany have now developed the first freestanding polymer brush, grafted from a crosslinked monolayer (nanosheet) that provides mechanical stability and structural integrity.

Nanotechnology Dangers Dangerous issue with Nanotechnology. Nanotechnology may cause problems
and Humans may suffer because of nanotechnology it has been claimed.
One way is such small particles as nanoparticles could be breathed in causing similar problems to that of asbestos. Another issue is that the nanoparticles may behave in unpredictable and dangerous way.
Even poisonous and or radioactive materials may be used causing problems to humans with nanotechnology.
Although once at the atomic size of nanoparticles atoms may behave differently.
Any mechanical device could be dangerous take all safely precaution's
Jeff Grossman, UC Berkeley, (video above), Talks about the growing
involvement of nanotechnology in solar power development. He starts off
with a discussion of the basics of Nanotechnology, the moves into the
challenges around new energy, and the limitations of traditional solar

those limitations, even though he doesn't believe those breakthroughs
will happen for a few years. Finally, Jeff addresses the concern of
nanotoxicity and exposure.

Toxic nanotechnology - a problem that could result in surprising benefits. (Nanowerk Spotlight) The fight against infections is as old as civilization. Silver,
for instance, had already been recognized in ancient Greece and Rome for its infection-fighting proerties and it has a long and intriguing history as an antibiotic in human health care. Modern day pharmaceutical companies developed powerful antibiotics - which also happen to be much more profitable than just plain old silver - an apparent high-tech solution to get nasty microbes such as harmful bacteria under control. In the 1950s, penicillin was so successful that the U.S. surgeon general at the time, William H. Stewart, declared it was "time to close the book on infectious diseases, declare the war against pestilence won." Boy, was he wrong! These days, the U.S. Centers for Disease Control and Prevention (CDC) estimates that the infections acquired in hospitals alone (of all places! it's 2007 and we can't even make our hospitals safe - how scary is that?) affect approximately 2 million persons annually. In the U.S., between 44,000 and 98,000 people die every year from infections they picked up in hospitals. As our antibiotics become more and more ineffective researchers have begun to re-evaluate old antimicrobial substances such as silver. Antimicrobial nano-silver applications have become a very popular early commercial nanotechnology product. Researchers have now made a first step to add carbon nanotubes to our microbe-killing arsenal.
Now is the time to wrestle with the ethics of this Pandora's Box Nanotechnology can learn much from history.
As the biotechnology industry recently discovered, ignoring public policy and social issues – namely, possible heath and environmental hazards from genetically modified foods – invites a public backlash that crippled progress and sent corporate stocks
plummeting.
If nanotechnology is billed as the "Next Industrial Revolution", It also must raise a host of important social and ethical questions that we need to consider now. Some of issues in "nanoethics." Many of them are
familiar to philosophy and ethics, but considering them in the context of nanotechnology is important and can reveal new insights.
Nanotechnology: benefits s toxic risks. A consequence of the new physical and chemical properties of nanotechnology, substances that could not have been used in a particular media previously because of instability or incompatibility (such as pH sensitivities or incompatibilities of solvents), may now have new applications. Some of these new nanotechnological advantages include enhanced solubilization, controlled delivery and absorption of ingredients.Could humans be infected by computer viruses? Dr Mark Gasson, from the School of Systems Engineering, contaminated a computer chip which had been inserted into his hand as part of research into human enhancement and the potential risks of implantable devices.
Groups Demand EPA Stop Sale of 200+ Potentially Dangerous Nano-Silver Products
Nanotech Watchdog Launches First-Ever Legal Challenge To EPA Over Unregulated Nanotech Pesticide Pollution. The International Center for Technology Assessment (CTA) and a coalition of consumer, health, and environmental groups today filed a legal petition with the Environmental Protection Agency (EPA), demanding the agency use its pesticide regulation authority to stop the sale of numerous consumer products now using nanosized versions of silver. The legal action is the first challenge to EPA's failure to regulate nanomaterials. International Center for Technology Assessment (CTA). Increasingly manufacturers are infusing a large and diverse number of consumer products with nanoparticle silver ("nano-silver") for its enhanced "germ killing" abilities. Nanosilver is now the most common commercialized nanomaterial. CTA found over 260 nano-silver products currently on the market, ranging from household appliances and cleaners to clothing, cutlery, and children's toys to personal care products and coated electronics. Yet as CTA's legal petition addresses, the release of this unique substance may be highly destructive to natural environments and raises serious human health concerns.

Nanodot normally focuses on longer-term nanotechnologies such as molecular manufacturing, but we do like to keep an eye on how different countries compare to each other in nanotech and technology in general.

U.S. Risks Losing Global Leadership in Nanotech
While the U.S. still leads the world in nanotech innovation by virtue of its size, Japan, Germany and South Korea are doing a better job of bringing technology to market, says Lux Research.
In terms of sheer volume, the U.S. dominated the rest of the world in nanotech funding and new patents last year, as U.S. government funding, corporate spending, and VC investment in nanotech collectively reached $6.4 billion in 2009. But according to a new report from Lux Research, countries such as China and Russia launched new challenges to U.S. dominance in 2009, while smaller players such as Japan, Germany and South Korea surpassed the United States in terms of commercializing nanotechnology and products.
Now, I don’t know why this may be the case, but speaking as someone running a small nonprofit in the U.S., the paperwork alone is a huge burden, and I know it’s worse in the case of for-profit companies and larger organizations. —Chris Peterson
IBM researchers in its Zurich lab have drawn–or rather, carved–a three-dimensional map of the world that’s 22 micrometers east to west by 11 micrometers north to south. At that size, about 15 of the maps could be wrapped end to end long-ways around a strand of human hair, by our math.
In a process the researchers describe in articles published today in Scienceand Advanced Materials, they used a silicon needle with a tip about ten thousand times smaller than an ant to sculpt a polymer material known as polyphthalaldehyde. By heating the needle to between 300 and 500 degrees centigrade, they were able to melt and evaporate tiny segments of the material without disturbing those particles’ neighbors…
IBM’s researchers hope that it could someday be used to craft circuit boards at smaller sizes than e-beam lithography is used to etch them today, or even build tiny nanobots or other tiny mechanical structures that could travel inside the human body or other nanoscale environments.
Longtime Foresight supporter John Gilmore writes: “I noticed a story that reminded me of something Foresight wanted to encourage in society. Wired reports that the CIA uses decision analysis software ‘Analysis of Competing Hypotheses’, and has funded a rewritten version for shared networked analysis by many people. But the gov’t contractors got into a hassle over who owned the code, so its developer is dumping it out into the open source world:
Analysis of competing hypotheses, sometimes abbreviated ACH, is a tool to aid judgment on important issues requiring careful weighing of alternative explanations or conclusions. It helps an analyst overcome, or at least minimize, some of the cognitive limitations that make prescient intelligence analysis so difficult to achieve.
ACH is an eight-step procedure grounded in basic insights from cognitive psychology, decision analysis, and the scientific method. It is a surprisingly effective, proven process that helps analysts avoid common analytic pitfalls. Because of its thoroughness, it is particularly appropriate for controversial issues when analysts want to leave an audit trail to show what they considered and how they arrived at their judgment.
“This reminded me of the ’science court’ process that Eric [Drexler] described decades ago in Engines of Creation. It sounds like it may have found an institutional home in the CIA and may be able to break out into broader society.”
Thanks for this, John. We’ll watch it with interest! —Chris Peterson

Many of you will recall Bill Joy’s famous article in Wired called Why the future doesn’t need us, where he expressed concern about various technologies including advanced nanotech. Apparently he gave an update of his views on this in his talk for TED, viewable here. An excerpt:
So if we can address, use technology, help address education, help address the environment, help address the pandemic, does that solve the larger problem that I was talking about in the Wired article? And I’m afraid the answer is really no, because you can’t solve a problem with the management of technology with more technology. If we let an unlimited amount of power loose, then we will — a very small number of people will be able to abuse it. We can’t fight at a million-to-one disadvantage. So what we need to do is, we need better policy. And for example, some things we could do that would be policy solutions which are not really in the political air right now but perhaps with the change of administration would be — use markets.
Whether you agree with him or not, it’s a useful discussion to have. As he says:
We can’t pick the future, but we can steer the future…So we can design the future if we choose what kind of things we want to have happen and not have happen, and steer us to a lower-risk place.
An article in New Scientist with the optimistic title “Artificial life forms evolve basic intelligence” gives an update on how two specific examples of computational artificial life is doing in terms of evolving to have more interesting behavior. An excerpt:
Brains that have been evolved with HyperNEAT have millions of connections, yet still perform a task well, and that number could be pushed higher yet,” he says. “This is a sea change for the field. Being able to evolve functional brains at this scale allows us to begin pushing the capabilities of artificial neural networks up, and opens up a path to evolving artificial brains that rival their natural counterparts.
See the comments after the article for useful discussion. A field to keep an eye on. —Chris Peterson
Nanowerk describes a recent advance toward the “e-nose” by an international team of researchers. Team member Andrei Kolmakov explains:
Our approach demonstrates the potential of combining bottom-up nanowire fabrication protocols with state-of-the art microfabrication methods to design prospective simple sensing arrays which, in principle, might be scaled down to the size of few micrometers and thus become the smallest analytical instrument…
Time for open source sensing! I’ll be speaking on this Friday at the Open Science Summit which starts tomorrow. Attend in person or watch the webcast. Hope to see you there. (Image: Dr. Kolmakov, Southern Illinois Univ. at Carbondale) —Christine Peterson
We’ve received an update on work by our friend Anirban Bandyopadhyay at the National Institute for Materials Science in Tsukuba, Japan. Here’s the abstract of his recent Nature Physics paper:
Modern computers operate at enormous speeds—capable of executing in excess of 1013 instructions per second—but their sequential approach to processing, by which logical operations are performed one after another, has remained unchanged since the 1950s. In contrast, although individual neurons of the human brain fire at around just 103times per second, the simultaneous collective action of millions of neurons enables them to complete certain tasks more efficiently than even the fastest supercomputer. Here we demonstrate an assembly of molecular switches that simultaneously interact to perform a variety of computational tasks including conventional digital logic, calculating Voronoi diagrams, and simulating natural phenomena such as heat diffusion and cancer growth. As well as representing a conceptual shift from serial-processing with static architectures, our parallel, dynamically reconfigurable approach could provide a means to solve otherwise intractable computational problems.
He explains:
…we have realized 700 bits parallel processing using cellular automaton for the first time in the world. This is a significant advancement from our 16 bit parallel processing which you highlighted in your website (http://www.foresight.org/nanodot/?p=2687)…This invention may be in coherence with the Feynman’s vision…We can solve some problems which computers will take more than the age of this universe. We did it in 6-10 minutes (in the Nature Physics paper).
Foresight Research Analyst and Technical Editor James Lewis has tracked the careers of those receiving Foresight’s student award. Here are his findings on the careers of a few of these gifted young researchers:
We at Foresight find it gratifying to track the subsequent careers of those who have won our nanotechnology-related prizes and awards, in this case the Foresight Distinguished Student Award, last made in 2007 to a Rice University graduate student, Fung-Suong Ou. Mr. Fung joins a distinguished group of winners who have launched impressive careers in nanoscience and nanotechnology. [ http://www.foresight.org/about/fi_spons.html#StudentAward ]
The Foresight Distinguished Student Award was established in 1997 and is given to a college undergraduate or graduate student whose work is notable in the field of nanotechnology. Typically, the nominations are made by the most prominent researchers in nanoscience and nanotechnology from among their most promising and productive students. The significance of the award is best exemplified by the distinguished careers of previous awardees. To cite only five spanning a wide area of nanoscience and the first eight years that the award has been made:
The first award was made to Phil Collins, then of the Department of Physics, University of California at Berkeley, and the Materials Sciences Division, Lawrence Berkeley National Laboratory, and currently Associate Professor, Physics & Astronomy, School of Physical Sciences, University of California at Irvine. He maintains an active research group in nanoelectronics, carbon nanotubes, and molecular electronics including sensors and bioelectronics. [reference http://www.physics.uci.edu/~collinsp/ ]
In 1998 the award was made to Fotis Nifiatis, then a graduate student at Hunter College, CUNY, for his work on metal-mediated self-assembly of large arrays and tapes. Currently on the Chemistry faculty at SUNY Plattsburgh, he continues research on coordination chemistry and photochemistry aiming to develop newer and more efficient molecular devices, the formation of supramolecular devices via self-assembly of porphyrins, and the application of two-photon initiated processes to microfabrication.
The 1999 award was made to Anita Goel, then an MD/PhD candidate at the Harvard/MIT Division of Health Sciences and Technology and also a PhD candidate at Harvard’s Physics Department. Ms. Goel was selected for her work on using optical and magnetic “tweezers” to probe the real-time single molecule dynamics of motor enzymes “dancing on DNA.” She was named one of the world’s “top 35 science and technology innovators under the age of 35″ by MIT’s Technology Review Magazine and is the Founder, Chairman, and CEO of Nanobiosym, Inc. From the Nanobiosym web site: “Her work on establishing the feasibility of the Gene-RADAR® technology platform at Nanobiosym® has been recognized by multiple rounds of funding from the United States Department of Defense agencies including Defense Advanced Research Projects Agency (DARPA), Air Force Office of Scientific Research (AFOSR) and US Dept of Energy (DOE) and US Defense Threat Reduction Agency.” [references: http://www.technologyreview.com/tr35/Profile.aspx?TRID=97http://www.nanobiosym.com/chairman_ceo.html ]
In 2000 the Foresight Distinguished Student Award was won by Christopher Love, then a PhD candidate in Harvard’s Department of Chemistry and Chemical Biology. Mr. Love was selected for his work in architectures for molecular electronic computers and nanomanipulation of structures on surfaces. He had contributed to nanotechnology research at three major U.S. research laboratories, starting in MITRE’s Nanosystems Group at age 16, before becoming in 2007 an Assistant Professor in Chemical Engineering, Massachusetts Institute of Technology. There he has continued to apply his nanostructure toolkit to exploring the intricacies of the immune system. [reference http://www.the-scientist.com/careers/article/display/55948/
Among more recent awardees, in 2004 a Graduate Fellow at Nanorex Corporation and Syracuse University doctoral candidate, Damian Allis received the Foresight Distinguished Student Award for his work in the application of theoretical computational methods to the design and study of molecules and nanostructures, materials for molecular electronics, non-linear optical materials, and molecular building blocks and biomimetic principles. He is currently Research Assistant Professor, Department of Chemistry, Syracuse University where his research emphasizes computational quantum chemistry and molecular nanotechnology, including the design and simulation of molecules and nanostructures, and molecular-based materials for molecular electronics.

How will nanotechnology change the world? How will nanotechnology
change privacy? The impact of Nanotechnology on health, some may
live healthier and longer, (but who will it be and what will be the
impact of living longer?). Other Nanotech Issues
Nanotechnology is a rapidly moving and all-encompassing suite of technologies that promises to change almost every aspect of our lives, from our health to our security to our ability to create a sustainable environment. As part of a multi-component project,
Fred Friendly Seminars is producing a three-part series - Nanotechnology: The Power of Small - that will explore the social, ethical, and legal implications of this field.

Clusters of heated, magnetic nanoparticles targeted to cell membranes can remotely control ion channels, neurons and even animal
behavior, according to a paper published by University at Buffalo physicists in Nature Nanotechnology. The research could have broad application, potentially resulting in innovative cancer treatments that remotely manipulate selected
proteins or cells in specific tissues, or improved diabetes therapies that remotely stimulate pancreatic cells to release
insulin.Using nanoparticles and a magnetic field, UB researchers were able to make worms reverse course when the nanoparticles were heated
to 34 degres Celsius. Video Credit: University at Buffalo. The work also could be applied to the development of new
therapies for some neurological disorders, which result from
insufficient neuro-stimulation."By developing a method that allows us to use magnetic fields to
stimulate cells both in vitro and in vivo, this research will help
us unravel the signaling networks that control animal behavior,"
says
Arnd Pralle, PhD, assistant professor of physics in the
University at Buffalo College of Arts and Sciences and
senior/corresponding author on the paper.The UB researchers demonstrated that their method could open
calcium ion channels, activate neurons in cell culture and even
manipulate the movements of the tiny nematode, C. elegans."We targeted the nanoparticles near what is the 'mouth' of the
worms, called the amphid," explains Pralle. "You can see in the
video that the worms are crawling around; once we turn on the
magnetic field, which heats up the nanoparticles to 34 degrees
Celsius, most of the worms reverse course. We could use this method
to make them go back and forth. Now we need to find out which other
behaviors can be controlled this way."
