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....

Blacksburg, Va. -- Chemistry and biology researchers at Virginia Tech have enhanced the abilities of the molecules they are creating to deliver killing blows to cancer cells. The man-made molecular complexes enter cancer cells and, when signaled, deliver killing medicine or cause the cell to change. The new supermolecules have more units that will absorb light "“ providing more control over the range of light frequencies that can be included and excluded as signals and the responses....

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...

UCLA chemists have created the first nano valve that can be opened and closed at will to trap and release molecules. The discovery, federally funded by the National Science Foundation, will be published July 19 in the Proceedings of the National Academy of Sciences. "This paper demonstrates unequivocally that the machine works," said Jeffrey I. Zink, a UCLA professor of chemistry and biochemistry, a member of the California NanoSystems Institute at UCLA, and a member of the research team....

22 June 2005 - A team of chemists at Penn State has developed a new type of ultrathin film, which has unusual properties that could improve the fabrication of increasingly smaller and more intricate electronic and sensing devices. The material, a single layer made from spherical cages of carbon atoms, could enable more precise patterning of such devices with a wider range of molecular components than now is possible with conventional self-assembled monolayers. The research is published in the...
