One bit of digital information stored on a hard disk currently consists of about 3 million magnetic atoms. Researchers from Karlsruhe, Strasbourg, and Japan have now developed a magnetic memory with one bit per molecule. By an electric pulse, the metal-organic molecule can be switched reliably between a conductive, magnetic state and a low-conductive, non-magnetic state. This novel correlation for molecules is now reported in the Nature Communications journal. (doi: 10.1038/ncomms1940)...

A team of chemists at the University of Geneva have finally demonstrated the utility of the rare halogen bond which acts as a anions transporter Professor Stefan Matile does not mention whether, as a child, he was a big fan of Lego. However, as an adult, he is fascinated by the game of molecular construction. Using the rules of chemistry, it is possible to artificially assemble all kinds of molecules and even nanomachines. However, chemists in this area feel their creativity constrained...

Researchers Create And Image Smallest 5-Ring Molecule

[ Watch the Video ] A collaboration of three groups is responsible for creating and imaging the smallest structure ever -- a billionth of a meter across and nearly 100,000 times thinner than a human hair. The structure, called olympicene, because of its five-ringed shape being similar to that of the Olympic symbol, was first synthesized by University of Warwick, UK researchers, who worked closely with IBM Research - Zurich to bring the molecule to life, employing a combination of...

For two molecules on blind date, new method predicts potential for attraction or repulsion Krzysztof Szalewicz, professor of physics and astronomy at the University of Delaware, and Rafal Podeszwa of the University of Silesia Institute of Chemistry in Poland have developed and validated a more accurate method for predicting the interaction energy of large molecules, such as biomolecules used to develop new drugs. The research is reported as a communication in the April 27 issue of the...

Wave Properties of Individual Heavy Molecules Can Also Be Observed Experimentally/Video Shows Development of Interference Pattern in (Nearly) Real Time Quantum theory describes the world of atoms very precisely. Still, it defies our macroscopic conception of everyday´s world due to its many anti-intuitive predictions. The wave-particle dualism probably is the best known example and means that matter may spread and interfere like waves. Now, an international team of researchers has...

A team of international researchers have fired ultra-fast shots of light at oxygen, nitrogen and carbon monoxide molecules as part of a development aimed at mapping the astonishingly quick movements of atoms within molecules, as well as the charges that surround them. The ultra-short laser that spans only a few hundred attoseconds — an attosecond is equivalent to one quintillionth of a second — was fired in a sample of molecules and could pave the way towards imaging the...

Atoms Caught Moving Within A Molecule

Using a new ultrafast camera, researchers have recorded the first real-time image of two atoms vibrating in a molecule. Key to the experiment, which appears in this week's issue of the journal Nature, is the researchers' use of the energy of a molecule's own electron as a kind of "flash bulb" to illuminate the molecular motion. The team used ultrafast laser pulses to knock one electron out of its natural orbit in a molecule. The electron then fell back toward the molecule scattered off...

Researchers at the universities of Granada and Barcelona have described for the first time the diffusion of liquid water through nanochannels in molecular terms; nanochannels are extremely tiny channels with a diameter of 1-100 nanometers that scientists use to study the behavior of molecules (nm. a unit of length in the metric system equal to one billionth of a meter that is used in the field of nanotechnology). This study might have an important impact on water desalinization and...

Researchers at the Nano-Science Center at the University of Copenhagen have developed a new nano-technology platform for the development of molecule-based electronic components using the wonder material graphene. At the same time, they have solved a problem that has challenged researchers from around world for ten years.  Since its discovery in 2004, graphene has been called a wonder material, in part because it is 200 times stronger than steel, a good electrical conductor and is just...

According to a new study, membranes based on the material graphene can be used to distill alcohol. The researchers wrote in the journal Science that they created the membrane from graphene oxide, which is a chemical derivative of graphene. Graphene is the thinnest known material in the universe and the strongest ever measured.  it conducts electricity and heat better the any other material as well. A University of Manchester academics won the Noble Prize in Physics in 2010 by...
