Much like a meteor impacting a planet, highly charged ions hit really hard and can do a lot of damage, albeit on a much smaller scale. And much like geologists determine the size and speed of the meteor by looking at the hole it left, physicists can learn a lot about a highly charged ion's energy by looking at the divots it makes in thin films. Building upon their work for which they were recently awarded a patent, scientists at the National Institute of Standards and Technology (NIST) and...

Separating carbon dioxide from its polluting source may soon be cleaner and more efficient, research at a California lab indicates. A Lawrence Livermore National Laboratory researcher developed a screening method that would use ionic liquids -- a type of molten salt that liquefies under the boiling point of water -- to separate carbon dioxide from its source, the Livermore, Calif., lab said Wednesday in a release. The method is cleaner, more viable and more stable than what is available now,...

Experts from Queen's University Belfast have developed new agents to fight MRSA and other hospital-acquired infections that are resistant to antibiotics. The fluids are a class of ionic liquids that not only kill colonies of these dangerous microbes, they also prevent their growth.The development of these new antimicrobial agents was carried out by a team of eight researchers from the Queen's University Ionic Liquid Laboratories (QUILL) Research Centre. The team was led by Brendan Gilmore,...

Certain explosives may soon get a little greener and a little more precise. LLNL researchers added unique green solvents (ionic liquids) to an explosive called TATB (1,3,5-triamino-2,4,6-trinitrobenzene) and improved the crystal quality and chemical purity of the material. This work, supported under the Transformational Materials Initiative (TMI) Laboratory Research and Development project, appears on the cover of the Sept. 1 issue of the journal Physical Chemistry Chemical Physics....

U.S. government scientists say they've developed a "green" method that makes some explosives safer and more stable. The Lawrence Livermore National Laboratory researchers say they added unique green solvents -- ionic liquids -- to an explosive called TATB and improved its crystal quality and chemical purity. "Improving crystal quality and purity leads to explosive materials that are (less likely to react violently) when subjected to mechanical impact or heat," said Larry Fried, the...

Researchers at Hampshire defense and security firm Qinetiq are currently testing ion thrusters, which they hope will one day bring spacecraft to the planets through solar energy.The ion engines create thrust by the acceleration if ions by electromagnetic forces. They make use of the fact that a current flowing across a magnetic field creates an electric field directed sideways to the current.This is used to accelerate a beam of ions of xenon away from the spacecraft, thereby providing...

NEW BRUNSWICK/PISCATAWAY, N.J. "“ Safe, versatile and environmentally friendly chemicals could replace hazardous, petroleum-based solvents used in science labs and industrial plants. Chemists at Rutgers, The State University of New Jersey, reported research results this week on a new class of ionic liquid chemicals with these attributes. Rutgers chemistry researchers Hideaki Shirota and Edward Castner, writing in the American Chemical Society's Journal of Physical Chemistry B, describe...

(Kingston, ON) "“ Researchers from Queen's University and the Georgia Institute of Technology have discovered a new environmentally-friendly way to make chemicals for pharmaceutical and other industries, such as plastics, pesticides, dyes and fragrances. The team, led by Queen's chemist Dr. Philip Jessop, has developed new solvents (liquids that dissolve other substances) that are both cleaner and cheaper when used in the production of many chemicals. Because each step in a chemical...

In chemistry, salt is a general term used for ionic compounds composed of positively charged cations and negatively charged anions, so that the product is neutral and without a net charge. These ions can be inorganic (Cl-) as well as organic (CH3-COO-) and monoatomic (F-) as well as polyatomic ions (SO42-). Solutions of salts in water are called electrolytes. Electrolytes as well as molten salts conduct electricity. Zwitterions are salts that contain an anionic center and a cationic...
