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...

One Chemical, Two Colors Of Crystals, Sheds Insight On Agostic Bonds Important In Industrial Catalysis
2013-08-04 07:48:34

DOE/Pacific Northwest National Laboratory Chemists have unexpectedly made two differently colored crystals -- one orange, the other blue -- from one chemical in the same flask while studying a special kind of molecular connection called an agostic bond. The discovery, reported in Angewandte Chemie International Edition on July 29, is providing new insights into important industrial chemical reactions such as those that occur while making plastics and fuels. "We were studying agostic...

Quantum Tunneling Is The Secret To Alcohol Reactions In Space
2013-06-30 12:56:40

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online Understanding chemical reactions in space is incredibly difficult. First of all, the extremely cold temperatures would all but preclude most chemicals mixing, as there is simply insufficient energy to ignite the reactions. Yet, observational data suggests that complex compounds are being created in this inhospitable environment. Now, however, a new study reveals that a quantum effect known to be the key in stellar physics may...

All Possible Drug-like Chemical Compounds Mapped By Scientists
2013-04-23 09:00:43

Duke University Software builds "library" of millions of small, carbon-based molecules chemists might synthesize. Drug developers may have a new tool to search for more effective medications and new materials. It's a computer algorithm that can model and catalogue the entire set of lightweight, carbon-containing molecules that chemists could feasibly create in a lab. The small-molecule universe has more than 10^60 (that's 1 with 60 zeroes after it) chemical structures. Duke...

Making Contact Between Metal And Carbon Compounds
2013-02-18 07:59:56

Helmholtz Association of German Research Centres Until now, however, it was practically impossible to accurately predict which molecules performed well on the job. They basically had to be identified by trial-and-error. Now, an international team of scientists around Dr. Georg Heimel and Prof. Norbert Koch from the HZB and the Humboldt University Berlin has unraveled the mystery of what these molecules have in common. Their discovery enables more focused improvements to contact layers...
