Penn Researchers Take a Big Step Forward in Making Smaller Circuits

 

PHILADELPHIA --  Physicists at the University of Pennsylvania have overcome a major hurdle in the race to create nanotube-based electronics.  In an article in the August issue of the journal Nature Materials, available online now, the researchers describe their method of using nanotubes tiny tubes entirely composed of carbon atoms -- to create a functional electronic circuit.  Their method creates circuits by dipping semiconductor chips into liquid suspensions of carbon nanotubes, rather than growing the nanotubes directly on the circuit.

"Given their amazing electric properties, nanotubes have been a subject of keen interest for creating such things as chemical sensors, flexible electronics and high-speed, high-device-density microprocessors for computing," said Alan T. Johnson, associate professor in Penn's Department of Physics and Astronomy.   "The problem is that the properties we like best about nanotubes their size and physical properties also make them very difficult to manipulate."...read the wave

 

 

Nano Debate : Global

Special Report - NanoGeoPolitics:
ETC Group Surveys the Political Landscape

 

Fearful that nanotech may face the same fate as biotech crops, the G8 used their Gleneagles summit to promote "new technologies" (including nanotech and biotech) as the magic bullet to "make poverty history" and to neutralize global warming. By hinting at the availability of billions for science capacity-building in the South, the North hopes to make allies of South governments, scientists, development NGOs, and environmentalists. Meanwhile, the real action is behind the scenes where various government/industry and scientific institutions are rushing to negotiate what the EU hopes will become a nanotech "code of conduct"(but, in light of US opposition may turn into a "framework of shared principles") and lay down the global standards, regulations, and market modus operandi for the greatest industrial revolution society has ever (not) seen coming. Social policy is being replaced by science policy. In this special report, ETC Group reviews the emerging nanogeopolitics landscape...read the wave

Single molecule is in driver's seat of molecular machine

 

EVANSTON, Ill. --- While the human body has plenty of specialized molecular motors and machines powering the mechanical work necessary for cells to function properly, scientists themselves face many hurdles as they try to create their own molecular machines in the laboratory.

The downsides of conventional molecular machines are that they are driven as an ensemble, by external light or chemistry, for example, and they are big -- made up of many molecules. These factors make these machines difficult to control.

In a theoretical paper published in the journal Physical Review Letters, two Northwestern University chemists have shown how molecular machines can be driven individually (relying on only one molecule) by applying an electric current that creates an internal energy source.

"People envision using molecular machines for computing techniques, sensors, bioengineering and solar cells, for example," said Tamar Seideman, professor of chemistry, who led the research team. "Molecular machines have unique...read the wave

Atomic force microscopy : How cell membranes respond to their environment

 

Some 25% of genes code for membrane proteins. Yet membrane organization remains a mystery. Membranes envelop all the cells in our bodies, forming a natural barrier, the membrane proteins within these can also recognize certain cells and direct a drug to them.

Using atomic force microscopy, Simon Scheuring (Inserm), in a CNRS unit at the Institut Curie, and James N. Sturgis, professor at the Université de la Méditerranée (CNRS unit), have studied the organization of a bacterial membrane and how it adapts in response to external factors. This is the first time that the inner workings of a membrane have been unveiled. Scheuring and Sturgis show that the organization of membrane proteins is not fixed but can vary with membrane location and time.

Italian research opens door to new hydrogen production method

 

Researchers in Italy have developed a new technique for producing hydrogen, and for purifying polluted gases.

The technique involves the release of oxygen from cerium oxide, a pale yellow-white powder used in ceramics and to polish glass.

'Ceria-based materials are oxygen buffers, materials that allow [one] to efficiently store or release oxygen, thus favouring a high catalytic activity and inducing a set of chemical reactions which would otherwise require higher pressures and temperatures,' says Friedrich Esch from the TASC INFM-CNR laboratory. The findings could therefore make an important contribution towards energy conservation, increasing the safety of industrial processes, and reducing environmental impact

Nanotech Buyers and Sellers Stuck in a Pricing Stalemate

 

NEW YORK, /PRNewswire/ -- Are high prices a barrier to nanotechnology commercialization? The answer is yes, according to a new report from Lux Research entitled "Nanotech's Pricing Stalemate Ends." In a remarkable disconnect, 75% of large corporations that buy components based on nanotechnology believe that they hold the pricing power in deals, while 70% of sellers think that in fact they have the upper hand. The result: Deals languish while corporate buyers use delay tactics on overeager sellers.

"Pricing is cited by 45% of corporate buyers as a major challenge that often impedes nanotech deals. Buyers lament that sellers frequently pay attention only to the cost of their own components, missing the big-picture view," said Lux Research Senior Analyst David Lackner. "Only 15% of sellers, however, see pricing as a major problem. They have such faith in their products' performance gains that they view pricing as a minor issue that will work itself out." ...read the wave

The next issue of Science will report a study that explains the mechanism for oxygen release by cerium oxide. This material is an important catalyst that favors many fundamental reactions that have profound implications for energy storage and environmental issues. These reactions include, for example, the purification of polluted gases and the production of hydrogen as new energy vector for fuel cells. The present study could inspire the design of new efficient catalysts for producing a large variety of goods, e.g. plastic materials, fuels, fertilizers and drugs.

Physicists Entangle Photon and Atom in Atomic Cloud

 

Physicists at the Georgia Institute of Technology have just reached an important milestone in the development of these systems by entangling a photon and a single atom located in an atomic cloud. Researchers believe this is the first time an entanglement between a photon and a collective excitation of atoms has passed the rigorous test of quantum behavior known as a Bell inequality violation. The findings are a significant step in developing secure long-distance quantum communications. They appear in the July 22, 2005 edition of the Physical Review of Letters .

Relying on photons or atoms to carry information from one place to another, network security relies on a method known as quantum cryptographic key distribution. In this method, the two information-carrying particles, photonic qubits or atomic qubits, are entangled. Because of the entanglement and a rule in quantum physics that states that measuring a particle disturbs that particle, an eavesdropper would be easily detected because the very act of listening causes changes in the system...read the wave

Molecular recognition plays an important role in biological processes. In general, it involves fairly weak interactions between individual molecular fragments. However, markedly strong bonds are occasionally observed, such as those between antibodies and their antigens. One reason for this seems to be that antigens can have multiple binding sites, to which multiple antigen-binding sites in the antibody can bind at the same time. This once again demonstrates that the whole can be more than the sum of its parts; the multiple interactions are stronger than would be expected from the corresponding individual bonds. In addition, the specificity of the molecular recognition is higher.

RIVERSIDE, Calif. www.ucr.edu – Osteoporosis sufferers and victims of broken bones may have the tiniest of friends in carbon nanotubes, according to researchers at the University of California, Riverside.

The strength, flexibility and light weight of carbon nanotubes – structures 100,000 smaller than a human hair – allow them to act as scaffolds to hold up regenerating bone, according to Distinguished Professor of Chemistry Robert C. Haddon , the director of the Center for Nanoscale Science and Engineering at UC Riverside.

“They're the perfect replacement: Small, strong, and they're carbon based,” said Haddon, lead author of a paper titled A Bone Mimic Based on the Self-Assembly of Hydroxyapatite on Chemically Functionalized Single-Walled Carbon Nanotubes, which was published in June in the American Chemical Society's journal Chemistry of Materials .

Watching the birth and death of exotic molecules

 

Researchers from Korea, Italy, France and the ESRF have just observed how a molecule changes structure after being hit with a short flash of laser light. Thanks to very intense pulses of X-rays from the synchrotron and novel data analysis, they were able to confirm a long standing hypothesis regarding the evolution of this molecule. The results are published in the 14 July Science Express, the online counterpart of the journal Science.

The experiment was started by dissolving the molecule C2H4I2 in liquid methanol and then hitting it with a short laser pulse. This excited the molecule, which then cooled down while releasing heat into the surrounding liquid. As a consequence, the temperature rose and the liquid started to expand in response to the increase in temperature. The absorption of light triggered a chemical reaction, which the researchers studied with picosecond time resolution. They measured the change in shape and composition as early as 100 picoseconds after the initial explosion, then at 10 nanoseconds after, then 1 microsecond and so on. All these dancing atoms were confined to a tiny “dance floor” with a radius of about 6 Ångstroms (0.6 nanometres)...read the wave

Circuit Elements for Optical Frequencies

 

Researchers at the University of Pennsylvania propose to shrink circuits in order to save space and power and, more importantly, to accommodate electronic applications at much higher frequencies than are possible with current models, applications that include nano-optics, optical information storage, and molecular signaling.

Electric circuit elements, among them resistors, capacitors, and inductors, come in a variety of sizes to deal with a variety of applications at a range of frequencies. The familiar electrical grid, for example, operates at a frequency of 60 Hz. A circuit designed to process radio signals operates at the 100-megahertz range. A typical frequency domain for computers is 1 GHz. Higher still, microwave applications often operate at the 10-GHz (10 10 Hz) level...read the wave

Diamonds are a scientist's best friend

 

Do diamonds really last forever? That's the hope of University of Wisconsin-Madison researchers who are trying to solve the problems associated with building extremely small machines and having them withstand the test of time, wear and tear.

The problem is that these machines are so small - microscopic or smaller - that their moving parts cannot be assisted by lubricants; instead, they have to function in a dry state, like a car with no oil.

A really, really small car with no oil.

"They no longer behave in the same way as they do at the macro-scale, where materials may be far stronger, have more power to catalyze chemical reactions, be more optically responsive, and more," says Robert Carpick , associate professor of engineering physics. "That is why it is very interesting to study the fundamental physics of nanoscale materials and also to try to utilize these unique properties for real applications."

Nanoscale Fiber Optics

 

One-dimensional nanoscopic structures such as nanowires are important building blocks for future miniature opto-electronic components. Swiss researchers have now developed a new method for the production of nanowires; they use lipid membranes as “molds” and obtain high yields of cadmium chloride nanowires that behave as light conductors.

“Syntheses that use molecular molds have advantages,” explains Horst Vogel, “they are simple, work under mild conditions, and deliver unique, precisely defined nanostructures”. Vogel and his team selected phospholipid membranes as molds. Phospholipids consist of a water-friendly head group and water-repellent tail groups (hydrocarbon chains). In aqueous surroundings, they line up tail to tail into double-layered membranes. If these are dried carefully, stacks of membranes are formed, in which the head groups that point toward each other are separated by nanometer-wide water films. Some types of head groups are able to selectively bind certain positively charged ions.

This is the basis of the Swiss researchers' technique...read the wave

Synapses May Fire Neurotransmitters Like a Shotgun

 

Researchers have constructed a new detailed map of the three-dimensional terrain of a synapse — the junction between neurons which are critical for communication in the brain and nervous system. The “nano-map,” which shows the tiny spines and valleys resolved at nanometer scale, or one-billionth of a meter, has already proven its worth in changing scientists' views of the synaptic landscape.

Using the map as a guide, the research team, led by Howard Hughes Medical Institute investigator Terrence Sejnowski, has developed a biologically accurate computer simulation of synaptic function.

Predicting the Lifetime of Extreme UV Optics

 

Extreme ultraviolet lithography (EUVL) may be the next-generation patterning technique used to produce smaller and faster microchips with feature sizes of 32 nanometers and below. However, durable projection optics must be developed before this laboratory technique can become commercially viable. As part of its long-standing effort to develop EUVL metrology and calibration services (summarized in a recent paper*), the National Institute of Standards and Technology (NIST) is creating a measurement system for accelerated lifetime testing of the mirrors used in EUVL.

The light to be used in EUVL has a wavelength of only 13 nm. It can only be efficiently reflected with mirrors consisting of 50 alternating bi-layers of molybdenum and silicon, each only 7 nm thick and deposited with near-atomic-scale precision. So although the EUVL mirrors will be very large, up to 35 centimeter (cm) in diameter, they are actually incredibly precise nanostructured devices. A single commercial lithography instrument may require six of these mirrors at a cost of more than $1 million each...read the wave

Europe and Asia set to oust US from lead in science and engineering

 

Fifty years of US global dominance in science and engineering (S&E) may be coming to an end as America's share of graduates in these fields stagnates, while S&E degree numbers soar in European and Asian universities.

Richard Freeman, from the National Bureau of Economic Research in Washington, has published a paper showing that changes in the global job market for S&E workers are eroding US dominance in this field. This diminishes the US's comparative advantage in high tech production and creates problems for American industry and workers in favour of the EU and Asian emerging economies.

Illinois chemists spray their way to better catalysts

 

CHAMPAIGN, Ill. –– Using a technique called ultrasonic spray pyrolysis, researchers at the University of Illinois at Urbana-Champaign have created an improved catalyst for removing smelly sulfur-containing compounds from gasoline and other fossil fuels. The improved catalyst is a form of molybdenum disulfide, most commonly recognized as the black lubricant used to grease automobiles and machinery.

Molybdenum disulfide is made of long flat layers of molybdenum metal atoms sandwiched above and below by single atomic layers of sulfur. The interactions between sulfur-sulfur planes are weak, so they can easily slide past one another, providing excellent high-temperature lubrication.

NYU Physicists Find Way to Create Three-Dimensional Quasicrystals

 

New York University physicists have applied a ground-breaking nanotechnology method to create three-dimensional quasicrystals, highly ordered structures that, unlike conventional crystals, never repeat themselves.

Metallic quasicrystals created from exotic alloys have shown promise for storing hydrogen more efficiently than crystalline hosts. Their non-repeating structure has the potential to dramatically strengthen industrial and commercial products. The NYU quasicrystals, by contrast, are made of glass and plastic and have potentially revolutionary optical properties.

Quasicrystals, discovered in the mid-1980s, are different from crystals, whose periodic structures resemble the patterns of tiles on a bathroom floor. By contrast, quasicrystals do not have this property, called translational symmetry, but, like crystals, can be rotated into registry with themselves, a property called rotational symmetry

Fundamental limitation to quantum computers

This could pose a considerable problem for the development of a quantum computer

A quantum computer makes use of the fact that a quantum mechanical system -an electron, an atom or even a larger system such as a superconducting quantum bit - can simultaneously exist in two states. Normally one of the two states disappears as soon as the system comes into contact with the outside world.

Nanotubes inspire new technique for healing broken bones

 

Scientists have shown for the first time that carbon nanotubes make an ideal scaffold for the growth of bone tissue. The new technique could change the way doctors treat broken bones, allowing them to simply inject a solution of nanotubes into a fracture to promote healing.

The report appears in the June 14 issue of the American Chemical Society's journal Chemistry of Materials . ACS is the world's largest scientific society.

Bacteria Take the Path of Least Resistance

Findings may lead to new nano-devices and understanding of infection

 

Researchers have reported new information about how certain bacteria propel themselves from one place to another. Insight into bacterial micro-movement will benefit scientists and engineers developing nano-scale mechanical devices that may one day push fluids and transport molecules without the aid of pumps or electrical charges.

The findings, published in the June 30 issue of the journal, Nature, may also help elucidate how pathogens traverse the human body when causing disease.

Using a novel system of microscopic channels, Harvard University researchers separated individual Escherichia coli cells from their typical "swarm" and videotaped them as they swam over different types of surfaces. A laboratory workhorse and common gastrointestinal bacterium, E. coli , preferred to swim near a gel-like porous surface with characteristics similar to biological tissues rather than near a glassy, solid one. In fact, they swam next to the porous surface for much longer periods of time...read the wave

NanoBots or what?

 

Wateringen, The Netherlands 01-07-2005

Well what can I say ? We had it all last month. Firstly we lost our hosting for Two and a half days ( can anyone out there help us with a sponsored Hosting deal ? ).

Then those NanoBots struck again and munched up 18 days of Site stats,
I call them NanoBots because that's just as credible as the c**p explanation I received from my web hosting company, who in fact had no idea (a) what had happened or (b) how I could retrieve the lost 18 days of stats !

Likely for me I had saved the daily stats, and with a “nano “ bit of statistical juggling I am happy to report that June 2005 was our 2nd best month ever ( after May 2005 ).

So against all the odds it still looks very encouraging, with visitors from over 20 different countries surfing in daily for news & views !

In total our June 2005 county count listed a staggering 73 different country names, making Nano Tsunami a truly Global Brand ! Site Stats here

The design allows more electrical current to flow in and out of the silicon. The researchers believe the design is...read the wave

 

 

Nano Debate : Global

A Tiny Primer on Nano-scale Technologies ...and The Little BANG Theory

 

What is nanotechnology?

Nano-scale technology is a suite of techniques used to manipulate matter at the scale of atoms and molecules. "Nano" is a measurement - not an object. Unlike "biotechnology," where you know that bios (life) is being manipulated, "nanotechnology" speaks solely to scale. A "nanometre" (nm) equals one billionth of a metre. One human hair is about 80,000 nanometres thick. It takes ten atoms of hydrogen side-by-side to equal one nanometre. A DNA molecule is about 2.5 nm wide. A red blood cell is vast in comparison: about 5,000 nm in diameter. Everything on the nano-scale is invisible to the unaided eye and even to all but the most powerful microscopes.

Key to understanding the unique power and potential of nanotech is that, at the nano-scale (below about 100 nanometres), a material's properties can change dramatically - these unexpected changes are called "quantum effects." With only a reduction in size and no change in substance, materials can exhibit new properties such as electrical conductivity, elasticity, greater strength, different colour and greater reactivity - characteristics that the very same substances do not exhibit at the micro or macro scales. For example...read the wave

Clean Drinking Water — Without Using Chemicals

 

To ensure emergency water supplies, Siemens is using mobile water treatment units featuring membrane systems. In the aftermath of the tsunami catastrophe, for example, the company delivered Memcor AXIM mobile water treatment units to the devastated region. The system is equipped with membrane filtration modules that can produce up to 100 cubic meters of water daily, which is sufficient to supply a small town.

The Memcor AXIM membrane modules consist of approximately 10,000 porous synthetic fibers contained in a cylindrical housing. A pump forces the contaminated water from outside the module through the membrane to the inside. Finally, the filtered water is also disinfected to ensure it does not contain any viruses. The result is high-quality drinking water...read the wave

HP researchers propose new path to optical quantum computing

 

Researchers from HP Laboratories in Bristol, UK, have proposed an approach to distributed optical quantum computing with a technique that is highly efficient, flexible and scalable.

Quantum computing is expected to be much more powerful than conventional information processing. It should be able to search faster and simulate better, factor large numbers efficiently and virtually guarantee secure communications.

Optical quantum computing – using photons instead of electrons for computation – is one possible approach to quantum computing. The technology might still be several decades away from practical implementation.

The researchers – Dr Bill Munro and Dr Tim Spiller, of HP Labs Bristol, with Professor Kae Nemoto, of the National Institute of Informatics (NII), Tokyo – have proposed an approach that generates interactions between photons by using so-called weak optical nonlinearities and intense laser fields. The result is the creation of two-photon gates, the basic building blocks of a quantum computer...read the wave

Quantum Computing: The Future may be Nearer Than we Think

 

According to Wall Street Journal columnist Lee Gomes, you know an idea's time has come when it "starts to be taught to undergraduates as though it is old hat." Gomes says that's what led him to sit in on a session of UC Berkeley's senior-level course in "Qubits, Quantum Mechanics, and Computers" last spring, C/CS/Physics 191 — a course otherwise known as quantum computing.

Two people the columnist heard speak that day, teacher Michael Crommie and guest Thomas Schenkel, are both staff scientists at Berkeley Lab, Crommie in the Materials Sciences Division and Schenkel in the Accelerator and Fusion Research Division (AFRD). Crommie, who is also a professor of physics at UC Berkeley, studies atomic and molecular structures on surfaces. Schenkel is heading a project at Berkeley Lab to demonstrate hardware for a quantum computer.

"In our class we start with a foundation in quantum mechanics and only later build up to the machinery we might use," says Crommie. Crommie teams with Umesh Vazirani, an associate professor in UC Berkeley's Department of Electrical Engineering and Computer Sciences; the two created the course in concert with K. Birgitta Whaley, a UCB professor of chemistry....read the wave

A Sharper Focus for Soft x-rays

Zone Plate Lenses Capable of Better than 15-Nanometer Resolution

 

BERKELEY, CA – Progress in nanoscience and nanotechnology depends not only on examining the surfaces of things but on seeing deep inside biological organisms and material structures to identify what they're made of — and what electronic, magnetic, optical, and chemical processes may be in play

For measuring internal variations in shape, organization, magnetism, polarization, or chemical make-up over distances of a few nanometers (billionths of a meter), x-ray microscopy not only complements electron microscopy but also offers important advantages. The XM-1 x-ray microscope at the Advanced Light Source, located at the Department of Energy's Lawrence Berkeley National Laboratory, uses bright beams of "soft" x-rays to produce images that not only reveal structures but can identify their chemical elements and measure their electromagnetic and other properties as well...read the wave

Nano Debate : EU

NanoDialogue project to engage the public in a debate on nanotechnologies and nanosciences

 

The development of nanotechnologies and nanosciences (N&N) is still at an early stage, though the market for nanotechnology-based products is expected to rise to hundreds of billions of euro by 2010. To foster public debate on the developments of research in this field, the NanoDialogue project was recently launched under the European Union's Sixth Framework Programme (FP6).

While products using nanotechnologies are already on the market, and they already have a growing public profile through science fiction, public awareness of its real economic and social potential is probably still quite low. Dialogue on the societal and ethical issues raised by N&N, between researchers, citizens, civil society and business stakeholders, is becoming indispensable to democratic policy decisions in this area.

The European Commission is supporting specific actions to communicate N&N under the FP6 research work-programme in 'Nanotechnologies and nano-sciences, knowledge-based multifunctional materials and new production processes and devices' (NMP). The NanoDialogue project, or 'Nanodialogue - Enhancing dialogue on Nanotechnologies and Nanosciences in society at European level One', is being supported with a budget of 850,000 euro...read the wave

A giant step toward tiny functional nanowires

 

Carving a telephone pole is easy if you have the right tools, say a power saw and some large chisels. And with some much tinier tools you could even carve a design into a paper clip if you wanted to. But shrink your sights down to the nanoscale, to a nanowire that is 1,000 times smaller than the diameter of a paper clip, and you find there are no physical tools to do the job properly.

So a team of Northwestern University scientists turned to chemistry and developed a new method that can routinely and cheaply produce nanowires with gaps as small as five nanometers wide -- a feat that is unattainable using conventional lithographic techniques. The results will be published in the July 1 issue of the journal Science.

Carved gaps are essential to a nanowire's function, and controlling those gaps would allow scientists and engineers to design with precision devices ranging from tiny integrated circuits to gene chips and protein arrays for diagnostics and drug discovery...read the wave
