-The construction of complex man-made objects--a car, for example, or even a pizza--almost invariably entails what are known as "top-down" processes, in which the structure and order of the thing being built is imposed from the outside (say, by an automobile assembly line, or the hands of the pizza maker)."Top-down approaches have been extremely successful," says Erik Winfree of the California Institute of Technology (Caltech). "But as the object being manufactured requires higher and higher...

Plasmonics -- a possible replacement for current computing approaches -- may pave the way for the next generation of computers that operate faster and store more information than electronically-based systems and are smaller than optically-based systems, according to a Penn State engineer who has developed a plasmonic switch."If plasmonics are realized, the future will have circuits as small as the current electronic ones with a capacity a million times better," said Tony Jun Huang, James...

By Anonymous NANOTECHNOLOGY We encounter valves every day, whether in a water faucet, automobile carburetor, or bicycle tire tube. Valves also are present in the world of nanotechnology. A team of researchers headed by J. Fraser Stoddart and Jeffrey I. Zink at the University of California, Los Angeles, has developed a new nanovalve. In contrast to prior versions, which only function in organic solvents, this valve operates in an aqueous environment and under physiological...

Indiana University Bloomington chemists have designed an organic molecule that binds negatively charged ions, a feat they hope will lead to the development of a whole new molecular toolbox for biologists, chemists and medical researchers who want to remove chlorine, fluorine and other negatively charged ions from their solutions."What we've done is create an efficient synthesis that gives us access to a whole new family of binding agents," said Amar Flood, who reports the discovery with...

Bacteria can be made to spin spider silk Biological and medical research is on the threshold of a new era based on better understanding of how large organic molecules bind together and recognise each other. There is great potential for exploiting the molecular docking processes that are commonplace in all organisms to develop new drugs that act more specifically without adverse side effects, and construct novel materials by mimicking nature. A recent workshop on Biosupramolecular Chemistry...

A new rubber-like material created with the ability to "heal" itself is paving the way for the development of a wide variety of new products.Polymer chemist Ludwik Leibler developed the "supramolecular rubber" with his colleagues at the Industrial Physics and Chemistry Higher Educational Institution (ESPCI) in Paris, France.When light pressure is applied to the fractured pieces of rubber at room temperature, they form a hydrogen bond and about 15 minutes later become one piece that is just as...

By Rostro, Betty Catalina Water is one of nature's most amazing fluids-and the hydrogen bond is the key to understanding its peculiar, eccentric and mesmerizing properties. Water is all over-two-thirds of the planet is covered by it-sometimes where we need it, sometimes not. Water is, in the words of Nobel Prize winner Albert Szent-Gyorgyi, "life's matter and matrix, mother and medium." Water seems such a simple substance, just two hydrogen atoms covalently bonded to a single oxygen atom,...

Blacksburg, Va. -- Chemists are several steps closer to teasing hydrogen fuel from water using man-made molecular devices that collect electrons and use them to split hydrogen from oxygen. Virginia Tech graduate students in chemistry will present two posters at the 230th national meeting of the American Chemical Society in Washington, D.C., Aug. 28 through Sept. 1, 2005, describing photochemical processes. Electrons are negatively charged particles that allow atoms to react and form bonds....
