Scientists say the Rydberg molecule, a molecule that until now existed only in theory, has finally been created, BBC News reported. The molecule is formed through an elusive and extremely weak chemical bond between two atoms. Researchers reported in the journal Nature that the new type of bonding occurs when one of the two atoms in the molecule has an electron very far from its nucleus or center. Nobel prize-winning physicist Enrico Fermi developed fundamental quantum theories about how...

Scientists in the US and Germany have discovered two of the most complex molecules ever to be found in space, and their scientific models imply that even larger molecules, such as amino acids, may also exist. Scientists from the Max Planck Institute for Radio Astronomy in Bonn, Germany, Cornell University in the US, and the University of Cologne in Germany have reported the discovery of ethyl formate and n-propyl cyanide in space. Using the IRAM 30 m telescope in Spain, the team discovered...

MANHATTAN, Kan., April 13 /PRNewswire-USNewswire/ -- Kansas State University engineers think the possibilities are deep for a very thin material. Vikas Berry, assistant professor of chemical engineering, is leading research combining biological materials with graphene, a recently developed carbon material that is only a single atom thick. "The biological interfacing of graphene is taking this material to the next level," Berry said. "Discovered only four years ago, this material has already...

Chemists at the University of Illinois have created a simple and inexpensive molecular technique that replaces an expensive atomic force microscope for studying what happens to small molecules when they are stretched or compressed.The researchers use stiff stilbene, a small, inert structure, as a molecular force probe to generate well-defined forces on various molecules, atom by atom."By pulling on different pairs of atoms, we can explore what happens when we stretch a molecule in different...

To be useful in real-world applications, a self-assembled monolayer (SAM) of molecules on a surface must have a stable and controllable geometry. Researchers at Penn State and the Sigma-Aldrich company have found a way to control geometry and stability by making SAMs out of different carboranethiol isomers, which are cage-like molecules. The research results will be published in the March 2009 issue of the journal ACS Nano."Our results allow us to control the chemical and physical properties...

When the University of Chicago's David Mazziotti talks about chemistry, perhaps he is thinking about how the behavior of all of the electrons in a molecule can be anticipated from the behavior of just two of its electrons.For 50 years theoretical chemists have puzzled over the problem of predicting many-electron chemistry with only two electrons, which many thought intractable and perhaps impossible to solve. Mazziotti, an associate professor in chemistry, will present a new approach to...

A former military technology can make almost any surface or fabric waterproof but remain breathable. Originally, the process was developed to ensure soldiers' clothing remained impermeable to chemical weapons. Now the developers of the process have signed a deal with shoemaker Hi-Tec to use the technology to waterproof many of its shoes. This week was the first commercial debut of the treated shoes in London. The Ministry of Defence funded the technology and it was developed at its Defence...

By Castelvecchi, Davide Bond lengths are different in heavy, light water molecules Heavy water is not just heavier. Swapping each H in H2O with a D- hydrogen's isotope deuterium - changes water's properties. The deuterium version is mildly poisonous, and its freezing point is 4[degrees] Celsius, instead of 0[degrees]C Such differences reveal that quantum effects, which aren't usually manifest to the naked eye, rule in ordinary water, researchers suggest. Alan Soper of the Rutherford...


Word of the Day
penuche
  • A fudgelike confection of brown sugar, cream or milk, and chopped nuts.
'Penuche' is a variant of 'panocha,' a coarse grade of sugar made in Mexico. 'Panocha' probably comes from the Spanish 'panoja, panocha,' ear of grain.
