Nanoscientists Describe Electron Movement through Molecules

 

ATHENS, Ohio — Molecular electronics is the ultimate miniaturization of electronics. In this area of research, scientists have been studying the movement of electrons through individual molecules in an effort to understand how they might control and use the process in new technologies. Computers and thousands of other devices could become vastly faster, smaller and more reliable than conventional transistor-based (wire-based) electronics.

A team of Ohio University and Brazilian physicists has taken another step toward this goal. In the Rapid Communication section of the Sept. 15 issue of the journal Physical Review B , the researchers present a new theory of how electrons interact in a molecule.

In the new paper, the team describes what happens to electrons when scientists put two molecules between electrodes, which are bits of tiny conducting wire. Existing theoretical models of molecular electronics take into account that electrons avoid each other, according to Nancy Sandler, Ohio University assistant professor of physics and astronomy. The scientists report that molecular vibrations, in addition to strong electronic interactions, will produce unexpected “transport channels.” The electrons move through the molecule while the molecule vibrates, said Sergio Ulloa, co-author of the paper and Ohio University professor of physics and astronomy...read the wave

‘Defective' Nanostructures Make Breaking Water to Extract Hydrogen Easier

 

Scientists at North Carolina State University have discovered a nanoscale method for extracting hydrogen from water that requires only half the energy of current hydrogen production methods.

The researchers discovered that “defective” carbon nanotubes make it easier to “break” water molecules and extract hydrogen.

The discovery could have big implications, namely, lower hydrogen production costs, for industries looking to hydrogen as an alternative fuel.

The scientists – NC State Department of Physics professor Dr. Marco Buongiorno-Nardelli; Dr. Keith Gubbins, W.H. Clark Distinguished University Professor of Chemical and Biomolecular Engineering; post-doctoral researcher Milen Kostov; and students Erik Santiso and Aaron George – published their results in the Sept. 30 edition of Physical Review Letters....read the wave

 

 
| What can be observed on a surface? | Masaru TSUKADA |


Tremendous progress has been made in surface physics since the invention of the scanning tunneling microscope (STM) in 1982. Even though atomic images were obtained, how exactly they were taken was unknown. "In order to determine the mechanisms, I developed a method to do theoretical simulations using first principle computations. From the simulation, I found that the tunneling current concentrated on the atom of the probe closest to the sample surface, and this was the key to STM with atomic scale resolution," said Prof. Tsukada....read the wave

Scientists create two-sided nanoparticles

 

ANN ARBOR, Mich.---As with many things in nature, including nanoparticles, two are better than one.

Scientists at the University of Michigan have used electricity to create nanoparticles with two sides, similar to how a fish bobber is made of two colored half shells. The technique could fuel a new research direction in the field, because the limits of size and shape are expanded, said Joerg Lahann, assistant professor of chemical engineering at U-M.

The new particles are exciting for several reasons, Lahann said, and could be used in many applications including targeted drug delivery, or to create new self-assembling particles. The big advantage is that the two sides, or phases, may be modified separately.

A good way to understand this is to picture two full water balloons squished into a see-through jar. The membranes are pressed together but the contents of each balloon could differ, because the membrane separates the two balloons. Scientists could load two different drugs into the particles, one on each side, for use in targeted drug delivery

Manipulation of single atoms provides fundamental insights

 

It seemed like science-fiction just a few years ago, but is now common practice for scientists at the Paul Drude Institute for Solid State Electronics (PDI) in Berlin. The scientists manipulate single atoms resting on surfaces and assemble them into wires or tiny clusters. In the world of nanometric dimensions, fundamental material properties such as magnetism, electrical conductivity or chemical reactivity differ from the conventional behaviour observed in everyday life. If metal clusters or semiconductor crystals are made just tiny enough, effects often arise which can be only explained by the laws of quantum physics. Recently, a team of scientists at the PDI documented the transition of the quantum world characteristics of atomic structures to the world of macroscopic material properties. They assembled individual copper atoms on a crystalline copper surface and examined the electronic properties of these artificial structures.

Nanotube films as sticky as a gecko's foot

 

Geckos are lizards with an impressive capacity to walk upside down on almost any surface, using just the attractive forces created by their feet to hold on. Borrowing the miraculous mechanism of the creature's feet, CAS researchers have succeeded in producing superhydrophobic nanotube films noted for their high adhesion.

How can geckos run upside down on polished glass? Some think that the creatures have suction cups on their feet, others say it is due to electrostatic attraction, and still others believe that they use hooks or claws or secrete glue on their feet. The question kept puzzling people for years until 2000, when a study published in Nature found that amazing climbing ability of geckos can be attributed to their nearly five hundred thousand tiny elastic hairs called setae, each of which branches at the end into up to 1,000 even tinier fibers called spatulas

Molecule Walks Like a Human

Moving one step at a time, newly designed molecule walks in a straight line; potential applications in molecular computing

 

RIVERSIDE, Calif. – A research team, led by UC Riverside's Ludwig Bartels , is the first to design a molecule that can move in a straight line on a flat surface. It achieves this by closely mimicking human walking. The “nano-walker” offers a new approach for storing large amounts of information on a tiny chip and demonstrates that concepts from the world we live in can be duplicated at the nanometer scale – the scale of atoms and molecules.

The molecule – 9,10-dithioanthracene or “DTA” – has two linkers that act as feet. Obtaining its energy from heat supplied to it, the molecule moves such that only one of the linkers is lifted from the surface; the remaining linker guides the motion of the molecule and keeps it on course. Alternating the motions of its two “feet,” DTA is able to walk in a straight line without the assistance of nano-rails or nano-grooves for guidanc

Innos, the UK's leading research and development company delivering expertise in silicon, MEMS and nanotechnologies, today announced its involvement in an EPSRC-funded project collaborative between Liverpool and Southampton Universities, which has demonstrated how high performance MOSFETs used in radio frequency applications can be manufactured at a low cost. The advance could enable more small to medium sized businesses to enter the radio frequency applications market and be used as part of a sensor network within ‘ambient intelligence' systems.

The research conducted at Liverpool and Southampton Universities shows how the adoption of vertical MOS transistors could enable a route to ultra-short channel MOS transistors using relaxed (hence cheaper) lithography rules and a reduced footprint. Classically, such devices are lateral but expensive lithography is required to achieve the ultra short channel lengths which are easily achieved with a vertical approach. The shortcomings of vertical transistors have been addressed by a number of novel solutions to drastically reduce parasitic effects generated by the geometric configuration of the device...read the wave

A Beam of Light on a Path of Gold to a Miniaturized World: Penn Theorists to Create Optical Circuit Elements

 

PHILADELPHIA – Engineers at the University of Pennsylvania have theorized a means of shrinking electronics so they could be run using light instead of electricity. In the search to create faster, smaller and more energy-efficient electronics, researchers have looked elsewhere in the electromagnetic spectrum, which ranges from the low-frequency energy used in everyday electronics to the high-frequency energy of gamma rays, to pass the limits of conventional technology.

In the Aug. 26 issue of Physical Review Letters, currently online, the Penn theorists outline how familiar circuit elements -- inductors, capacitors and resistors – could be created on the nanoscale (about a billionth of a meter) in order to operate using infrared or visible light. The Penn researchers describe how nanoscale particles of certain materials, depending on their unique optical properties, could work as circuit elements. For example, nanoscale particles of certain metals, such as gold or silver, could perform the same function in manipulating an "electric" current as an inductor does on a circuit board.

Breakthrough in micro-device fabrication combines biology and synthetic chemistry

 

ATLANTA, Ga. – Sept. 20, 2005 – Nanostructured micro-devices may be mass produced at a lower cost, and with a wider variety of shapes and compositions than ever before, for dramatic improvements in device performance by utilizing very small biologically produced structures. These entirely new biologically-enabled approaches are detailed in the current issue of the International Journal of Applied Ceramic Technology, published on behalf of The American Ceramic Society.

This study's newly invented approaches for the low-cost mass production of micro-devices could yield unprecedented breakthroughs in genetically engineered microdevices (GEMs) for biomedical, computing, environmental cleanup, defense and numerous other applications.

Conventional microfabrication processes, similar to methods used to make computer microchips, are expensive (i.e., capital equipment intensive) and not well-suited for directly producing large numbers of complex, three-dimensional, nanostructured devices with a wide variety of chemistries and properties. Nature, on the other hand, provides...read the wave

Carbon nanotubes inject antimycotics into cells and increase their effectiveness

 

Putting pharmaceutical agents into the body isn't hard, but getting them into targeted areas can be problematic. If drugs aren't taken up by a large enough proportion of cells, a suitable “transport agent” must be used. A French and Italian research team has successfully used carbon nanotubes as transport agents for antimycotics (antifungal agents). In addition, they have developed a strategy for attaching a second agent or marker to the nanotubes in a controlled fashion.

Carbon nanotubes are long, narrow nanoscale tubes made of multiple layers of carbon atoms arranged in graphite-like sheets. “They can drill through cell membranes like tiny needles,” explains Alberto Bianco, “without damaging the cell.” If proteins or nucleic acids are attached to the nanotubes, they come right along through the membrane.

Helping Out a High-Temperature Superconductor

 

Researchers at the U.S. Department of Energy's Brookhaven National Laboratory have discovered a way to significantly increase the amount of electric current carried by a high-temperature superconductor, a material that conducts electricity with no resistance. This is an important step in the drive to create superconductor-based electric and power-delivery devices, such as power transmission lines, motors, and generators. The results are explained in the September 12, 2005, online edition of Applied Physics Letters .

"In theory, superconducting materials can conduct an enormous amount of electric current. But when incorporated into actual devices, certain factors tend to limit the current," said Brookhaven materials scientist Qiang Li, a co-author on the paper. "We studied these factors and found that one, which we call 'substrate roughness,' can actually significantly increase the current-carrying capacity."

'Bowtie nanoantennas' could shed light on molecules, other nano-sized objects

Rapid One-Pot Syntheses Developed For Quantum Dots

New processes have applications in bioimaging and solar conversion

 

BUFFALO, N.Y. -- Efficient and highly scalable new chemical synthesis methods developed at the University at Buffalo's Institute for Lasers, Photonics and Biophotonics have the potential to revolutionize the production of quantum dots for bioimaging and photovoltaic applications.

A patent has been filed on the methods, which were described last month in papers in the Journal of the American Chemical Society and Applied Physics Letters.

Quantum dots are tiny semiconductor particles generally no larger than 10 nanometers that can be made to fluoresce in different colors depending on their size. Scientists are interested in quantum dots because they last much longer than conventional dyes used to tag molecules, which usually stop emitting light in seconds. Quantum dots also are of great interest for energy applications because they can produce electrons when they absorb light, making possible extremely efficient solar-energy devices.

Both fabrication methods developed by the UB researchers involve using a single container, or "pot," and take just a few hours to prepare...read the wave

A key technological breakthrough led by the University of Edinburgh suggests that a futuristic world where people can move objects about ‘remotely' with laser pointers could be closer than we think. Chemists working on the nanoscale (80,000 times smaller than a hair's breadth) have managed to move a tiny droplet of liquid across a surface – and even up a slope – by transporting it along a layer of light-sensitive molecules.

Scientists at Edinburgh, Groningen and Bologna are the first to manipulate tiny nanoscale machines (two millionths of a millimetre high) so that they can move an object that is visible to the naked eye. The team has shifted microlitre drops of diiodomethane not just across a flat surface, but also up a one millimetre, 12 degree slope against the force of gravity. It may be the tiniest of movements, but, in the emerging discipline of nanotechnology, it represents a giant technological leap forward..

Method Slashes Quantum Dot Costs By 80 Percent

 

Houston, TX, --- In an important advance toward the large-scale manufacture of fluorescent quantum dots, scientists at Rice University have developed a new method of replacing the pricy solvents used in quantum dot synthesis with cheaper oils that are commonplace at industrial chemical plants.

Rice's study, which was conducted under the auspices of the Center for Biological and Environmental Nanotechnology (CBEN), is published online and slated to appear in the October issue of the journal Nanotechnology .

"CBEN started to undertake some exploratory work more than a year ago on the scale-up issues of quantum dot manufacture, but the solvents turned out to be so expensive that we just couldn't afford to run more than a few large-reactor experiments," said the study's lead author, Michael Wong, assistant professor of chemical and biomolecular engineering and of chemistry. "That was a great reality check, and it made us look at the problem of solvent cost sooner rather than later."

Quantum dots typically cost more than $2,000 per gram from commercial sources, and pricy solvents like octadecene, or ODE - the least expensive solvent used in quantum dot preparation today - account for about 90 percent costs of raw materials.

This involves a base consisting of three aromatic rings which is bent like a boomerang. The central ring has a long, branched side-chain hanging from it.

BREAKTHROUGH IN DEVELOPMENT OF QUANTUM COMPUTERS

 

Hitachi Europe Ltd. has announced that a Hitachi-Cambridge team has developed a new silicon device for quantum computing: a quantum-dot charge qubit. This structure, based on years of work on single-electronics, is the first step in the development of a quantum computer based on conventional silicon technology.

The world's most powerful supercomputers could be made obsolete in the future, by a totally different approach to processing information. In a classical computer, the basic unit of information is the ‘bit', which can exist in one of two possible states, 0 or 1. Quantum computers make use of quantum bits (qubits), which can exist in a superposition of both states - a mixture of both 0 and 1 simultaneously. Qubits are also subject to quantum entanglement. When two or more are entangled, they behave as one system, so that the state of one qubit depends directly on the state of the others. Thus the potential processing power of a quantum information system increases exponentially rather than linearly with the number of qubits.

Although the principles behind quantum computing have been established and small model systems constructed, it still remains a considerable task to scale these up to practical, working computers. However, it is a valuable objective as it would make possible certain types of computation that are currently either impossible or impractical within a sensible timescale using classical computers. There are a raft of potential applications including bioinformatics, molecular modelling, codebreaking and encryption. Quantum computers could also be used as simulators to solve quantum mechanics problems...read the wave

About one three-hundredth (1/300) of the diameter of human hair, the device is small enough to travel through blood vessels and can carry drugs the same weight as itself.
The device's surface is full of cavities where drugs are stored. Magnetic material within the device helps it to be directed to target areas. When it arrives at its destination, the protective coating will dissolve and start to release the drug.

Two leading scientific magazines, Journal of the American Chemical Society and Germany's Angewandte Chemie, have published articles about the invention.

A nanometre is a metric unit of length equal to one billionth of a meter. Thanks to their ability to gain access throughout the body, nanometre-sized devices have the potential to treat diseases like cancers in previously inconceivable ways. Source : english.eastday.com

Argonne researchers create new diamond-nanotube composite material

 

ARGONNE, Ill. – Researchers at the U.S. Department of Energy's Argonne National Laboratory have combined the world's hardest known material – diamond – with the world's strongest structural form – carbon nanotubes. This new process for “growing” diamond and carbon nanotubes together opens the way for its use in a number of energy-related applications.

The technique is the first successful synthesis of a diamond-nanotube nanocomposite, which means for the first time this specialized material has been produced at the nanometer size – one-millionth of a millimeter, or thousands of times smaller than the period at the end of this sentence.

The result established for the first time a process for making these materials a reality, setting the stage for several fundamental advances in the field of nanostructured carbon materials.

The resulting material has potential for use in low-friction, wear-resistant coatings, catalyst supports for fuel cells, high-voltage electronics, low-power, high-bandwidth radio frequency microelectromechanical/nanoelectromechanical systems (MEMS/NEMS), thermionic energy generation, low-energy consumption flat panel displays and hydrogen storage...read the wave

Harder than diamond

 

Physicists in Germany have created a material that is harder than diamond. Natalia Dubrovinskaia and colleagues at the University of Bayreuth made the new material by subjecting carbon-60 molecules to immense pressure. The new form of carbon, which is known as 'aggregated diamond nanorods' (ADNR), is expected to have many industrial applications.

Due to combination of unique physical and chemical properties such as hardness, high thermal conductivity, wide band gap, high electron and hole mobility and chemical inertness, diamond has been used for a wide range of applications in modern science and technology. There is growing demand for diamond-like materials in electronic applications.

Although there is little prospect of diamond-based microelectronics ousting silicon totally, diamond devices could function in situations when silicon electronics fail: diamond chips potentially could still work at temperatures of several hundred degrees, whereas silicon devices generally fail above 450 degrees Kelvin.
