April Flowers for redOrbit.com - Your Universe Online Currently, heading off into space requires a shuttle, rocket or some sort of high velocity vehicle with enough power to push through Earth's atmosphere. What if you could take a "space elevator" instead? That is the hope of a team of scientists led by Penn State for a new type of nanothread they have created. The threads have been described in a recent issue of Nature Materials. Diamonds are the hardest naturally occurring material...

Tatiana Arizaga, UC Irvine Chemists further discover that it’s oscillating from one quantum state to another UC Irvine chemists have scored a scientific first: capturing moving images of a single molecule as it vibrates, or “breathes,” and shifts from one quantum state to another. The groundbreaking achievement, led by Ara Apkarian, professor of chemistry, and Eric Potma, associate professor of chemistry, opens a window into the strange realm of quantum mechanics – where...

Future Face Of Molecular Electronics

By Laurel Hamers, American Institute of Physics Thin layer of picene molecules attached to a silver surface maintain their structure and function, demonstrating potential for electronic applications The emerging field of molecular electronics could take our definition of portable to the next level, enabling the construction of tiny circuits from molecular components. In these highly efficient devices, individual molecules would take on the roles currently played by...

Two Exotic Forms Of Carbon Crafted Into A Molecule For Steering Electron Flow
2014-09-11 03:17:58

SLAC National Accelerator Laboratory Scientists have married two unconventional forms of carbon – one shaped like a soccer ball, the other a tiny diamond – to make a molecule that conducts electricity in only one direction. This tiny electronic component, known as a rectifier, could play a key role in shrinking chip components down to the size of molecules to enable faster, more powerful devices. "We wanted to see what new, emergent properties might come out when you put these two...

New Light Shed On Fundamental Ultrafast Dynamics

Kansas State University Ultrafast X-ray laser research led by Kansas State University has provided scientists with a snapshot of a fundamental molecular phenomenon. The finding sheds new light on microscopic electron motion in molecules. Artem Rudenko, assistant professor of physics and a member of the university's James R. Macdonald Laboratory; Daniel Rolles, currently a junior research group leader at Deutsches Elektronen-Synchrotron in Hamburg, Germany, who will be joining the...

A combined computational and experimental study of self-assembled silver-based structures known as superlattices has revealed an unusual and unexpected behavior: arrays of gear-like molecular-scale machines that rotate in unison when pressure is applied to them. Computational and experimental studies show that the superlattice structures, which are self-assembled from smaller clusters of silver nanoparticles and organic protecting molecules, form in layers with the hydrogen bonds between...

Chemiscope To Help Chemistry In Action
2014-03-18 05:09:00

redOrbit Staff & Wire Reports - Your Universe Online Researchers at the University of California, Irvine’s Center for Chemistry at the Space-Time Limit (CaSTL) have reportedly developed a new tool that could make it possible to observe the making and breaking of chemical bonds and how molecules behave during a chemical reaction. The device is known as the “chemiscope,” and according to CaSTL officials it could revolutionize chemistry in much the same way that the microscope...

New Boron Nanomaterial Could Be A Very Real Possibility
2014-01-28 10:55:00

Brown University Graphene, a sheet of carbon one atom thick, may soon have a new nanomaterial partner. In the lab and on supercomputers, chemical engineers have determined that a unique arrangement of 36 boron atoms in a flat disc with a hexagonal hole in the middle may be the preferred building blocks for “borophene.” Findings are reported in Nature Communications. Researchers from Brown University have shown experimentally that a boron-based competitor to graphene is a very real...

Researchers Create First Soluble 2D Supramolecular Organic Frameworks
2013-12-16 14:20:48

Lawrence Berkeley National Laboratory Supramolecular chemistry, aka chemistry beyond the molecule, in which molecules and molecular complexes are held together by non-covalent bonds, is just beginning to come into its own with the emergence of nanotechnology. Metal-organic frameworks (MOFs) are commanding much of the attention because of their appetite for greenhouse gases, but a new player has joined the field – supramolecular organic frameworks (SOFs). Researchers with the U.S....

One-of-a-kind spectrometer reads vibrations between atoms to find structures of molecules A Rice University laboratory has improved upon its ability to determine molecular structures in three dimensions in ways that challenge long-used standards. By measuring the vibrations between atoms using femtosecond-long laser pulses, the Rice lab of chemist Junrong Zheng is able to discern the positions of atoms within molecules without the restrictions imposed by X-ray diffraction (XRD) and...
