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

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.

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

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.

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...read the wave

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.

The mechanism of oxygen release was analyzed and described by studying the surfaces of cerium oxide (ceria). “Ceria-based materials are oxygen buffers, materials that allow to efficiently store or release oxygen, thus favoring a high catalytic activity and inducing a set of chemical reactions which would otherwise require higher pressures and temperatures” says Friedrich Esch (Laboratorio TASC INFM-CNR). “The production of more efficient catalysts is therefore of paramount importance for saving energy, increasing the safety of industrial processes, and reducing the environmental impact.”...read the wave

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. Researchers wish to use this phenomenon, known as multivalency, for the development of pharmaceuticals and targeted-imaging agents. “The idea is to attach several...read the wave
