Graphene is one of the wonders of the science world, with the potential to create foldaway mobile phones, wallpaper-thin lighting panels and the next generation of aircraft. The new finding at the University of Manchester gives graphene's potential a most surprising dimension — graphene can also be used for distilling alcohol. In a report published in Science, a team led by Professor Sir Andre Geim shows that graphene-based membranes are impermeable to all gases and liquids...

A Rice University research team makes graphene suitable for a variety of organic chemistry applications The Air Force Office of Scientific Research (AFOSR), along with other funding agencies, helped a Rice University research team make graphene suitable for a variety of organic chemistry applications–especially the promise of advanced chemical sensors, nanoscale electronic circuits and metamaterials. Ever since the University of Manchester's Andre Geim and Konstantin Novoselov...

To better understand the fundamental behavior of molecules at surfaces, researchers at the U.S. Department of Energy's Oak Ridge National Laboratory are combining the powers of neutron scattering with chemical analysis. Scientists have a fundamental interest in how molecules behave at solid surfaces because surface interactions influence chemistry, such as in materials for catalysis, drug delivery and carbon sequestration. Understanding these interactions allows researchers to tailor...

Delivery of pharmaceuticals into the human body and the storage of gas molecules for alternative energy could now be better controlled The delivery of pharmaceuticals into the human body or the storage of voluminous quantities of gas molecules could now be better controlled, thanks to a study by University of Pittsburgh researchers. In a paper published online today in Nature Communications, a team of chemists and colleagues from Pitt´s Kenneth P. Dietrich School of Arts and Sciences...

Targeted proton transfer within a molecule For a long time miniaturization has been the magic word in electronics. Dr. Willi Auwaerter and Professor Johannes Barth, together with their team of physicists at the Technische Universitaet Muenchen (TUM), have now presented a novel molecular switch in the journal Nature Nanotechnology. Decisive for the functionality of the switch is the position of a single proton in a porphyrin ring with an inside diameter of less than half a nanometer. The...

Individual molecules have been used to create electrical components like resistors, transistors and diodes, that mimic the properties of familiar semiconductors. But according to Nongjian (NJ) Tao, a researcher at the Biodesign Institute® at Arizona State University, unique properties inherent in single molecules may also allow clever designers to produce novel devices whose behavior falls outside the performance observed in conventional electronics. In research appearing in today's...

Rice researchers' two-step technique makes graphene suitable for organic chemistry The future brightened for organic chemistry when researchers at Rice University found a highly controllable way to attach organic molecules to pristine graphene, making the miracle material suitable for a range of new applications. The Rice lab of chemist James Tour, building upon a set of previous finds in the manipulation of graphene, discovered a two-step method that turned what was a single-atom-thick...

Controlling forces between oppositely charged polymers opens a new route towards creating vectors for gene therapy Gene therapy can only be effective if delivered by a stable complex molecule. Now, scientists have determined the conditions that would stabilise complex molecular structures that are subject to inherent attractions and repulsions triggered by electric charges at the surfaces of the molecules, in a study about to be published in EPJ E´, by Valentina Mengarelli and her...

The World's Smallest Electric Car Made Out Of Single Molecule
2011-11-11 06:29:35

Scientists have developed the world's smallest electric car, made from a single molecule. The molecule has four branches that act as wheels and rotate when a tiny metal tip helps apply a small current of electricity to them. The car was made to move six billionths of a meter with just 10 electric bursts. The car's "batteries" are a scanning tunneling microscope, which is a fine point of metal that ends in just an atom or two.  As the tip draws near the molecule, electrons jump...

A team of scientists led by a Penn State University chemist has demonstrated the strengths and weaknesses of an alternative method of molecular depth profiling -- a technique used to analyze the surface of ultra-thin materials such as human tissue, nanoparticles, and other substances. In the new study, the researchers used computer simulations and modeling to show the effectiveness and limitations of the alternative method, which is being used by a research group in Taiwan. The new...
