Changing Organic Molecules' Interaction With Light
2013-08-06 13:28:05

Massachusetts Institute of Technology, Institute for Soldier Nanotechnologies MIT researchers discover a new platform that provides simple means to manipulate organic molecules' emission, and may have important implications to organic light emitting devices and molecular biosensors Enhancing and manipulating the light emission of organic molecules is at heart of many important technological and scientific advances, including in the fields of organic light emitting devices, bio-imaging,...

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...

Molecules Captured At Work During Graphene Research
2013-05-31 11:30:19

Rebekah Eliason for redOrbit.com — Your Universe Online One of the hottest topics in chemical research right now is the study of graphene. This cutting edge compound, composed of a single layered sheet of hexagonal carbon atoms linked together, could be the next step in designing nanostructures for electronics and next-generation computers. Graphene nanostructures have the potential to form transistors, logic gates, and other parts for use in tiny electronic devices, but...

Buckyball Manipulated By Inserting A Single Water Molecule
2013-05-06 10:26:08

Columbia University Nanoscale technology used to drive a 'big' C60 through a 'small' H2O may help drug delivery Columbia Engineering researchers have developed a technique to isolate a single water molecule inside a buckyball, or C60, and to drive motion of the so-called "big" nonpolar ball through the encapsulated "small" polar H2O molecule, a controlling transport mechanism in a nanochannel under an external electric field. They expect this method will lead to an array of new...

IBM Makes World’s First Atomic Film
2013-05-01 11:10:17

Michael Harper for redOrbit.com — Your Universe Online Every now and then, it´s fun to show off and remind the world just what you´re capable of. IBM has done that today by releasing what they´re calling the “World´s Smallest Movie,” a short film composed entirely with atoms. As if this weren´t enough, the movie is also accompanied by another series of movies wherein the IBM team explains how they were able to manipulate individual atoms to do...

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...

RUB researchers give floppy molecule a structure through solvent effects How you get the chameleon of the molecules to settle on a particular "look" has been discovered by RUB chemists led by Professor Dominik Marx. The molecule CH5+ is normally not to be described by a single rigid structure, but is dynamically flexible. By means of computer simulations, the team from the Centre for Theoretical Chemistry showed that CH5+ takes on a particular structure once you attach hydrogen molecules....

Ancient Fossilized Sea Creatures Contain Oldest Biomolecules Taken Directly From A Fossil
2013-02-19 13:45:53

The Ohio State University Though scientists have long believed that complex organic molecules couldn´t survive fossilization, some 350-million-year-old remains of aquatic sea creatures uncovered in Ohio, Indiana, and Iowa have challenged that assumption. The spindly animals with feathery arms–called crinoids, but better known today by the plant-like name “sea lily”–appear to have been buried alive in storms during the Carboniferous Period, when North America...

Berkeley Lab research at AAAS Meeting In the blink of an eye, more attoseconds have expired than the age of Earth measured in — minutes. A lot more. To be precise, an attosecond is one billionth of a billionth of a second. The attosecond timescale is where you must go to study the electron action that is the starting point of all of chemistry. Not surprisingly, chemists are most eager to explore it with X-rays, the region of the electromagnetic spectrum that can probe the core...

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...


Word of the Day
siliqua
  • A Roman unit of weight, 1⁄1728 of a pound.
  • A weight of four grains used in weighing gold and precious stones; a carat.
  • In anatomy, a formation suggesting a husk or pod.
  • The lowest unit in the Roman coinage, the twenty-fourth part of a solidus.
  • A coin of base silver of the Gothic and Lombard kings of Italy.
'Siliqua' comes from a Latin word meaning 'a pod.'
