What Does Water Looks Like To DNA?
2013-11-20 09:41:53

American Institute of Physics New computational method described in the Journal of Chemical Physics allows researchers to predict how biological molecules interact with water A team of biochemists and mathematicians have developed a sophisticated geometric model to predict how a biological molecule will interact with water molecules, computing the results up to 20 times faster than other existing approaches. This new approach may help researchers find new drugs to treat human...

Nanomachines: Devices Of The Future
2013-08-28 09:42:10

Institute of Physical Chemistry of the Polish Academy of Sciences An innovative measurement method was used at the Institute of Physical Chemistry of the Polish Academy of Sciences in Warsaw for estimating power generated by motors of single molecule in size, comprising a few dozens of atoms only. The findings of the study are of crucial importance for construction of future nanometer machines – and they do not instil optimism. Nanomachines are devices of the future. Composed of a...

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...

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....


Word of the Day
caparison
  • A cloth or covering, more or less ornamented, laid over the saddle or furniture of a horse, especially of a sumpter-horse or horse of state.
  • Clothing, especially sumptuous clothing; equipment; outfit.
  • To cover with a caparison, as a horse.
  • To dress sumptuously; adorn with rich dress.
This word ultimately comes from the Medieval Latin 'cappa,' cloak.
