Physicists control molecule for a millionth of a billionth of a second

Physicists control molecule for a millionth of a billionth of a second

Science
Sept. 7 (UPI) -- Using a microscope and its electrical current, physicists have found a way to manipulate and control a single molecule. The breakthrough happened by accident. In the lab, scientists were observing a basic chemical reaction under an electron microscope. Normally, when the current of the microscope is increased, the reaction happens faster. This time, it didn't. "This was data from an utterly standard experiment we were doing because we thought we had exhausted all the interesting stuff -- this was just a final check," Kristina Rusimova, physicist at the University of Bath, said in a news release. "But my data looked 'wrong' -- all the graphs were supposed to go up and mine went down." Scientists at Bath spent months trying to explain the anomaly. After repeating their exp...

Physicists build 2D platinum magnet

Science
April 6 (UPI) -- Scientists have induced magnetism in 2D platinum using a paramagnetic ionic liquid.Platinum is a superb conductor but features no magnetic properties. But using an electric field created by the paramagnetic ionic liquid, scientists produced a ferromagnetic state on the surface of the platinum sheet."You can tune magnets electrically by changing the number of carriers inside, which is one of the key ideas in spintronics. But so far, no one could generate magnets like that," Justin Ye, a material scientist at the University of Groningen in Germany, said in a news release.Ionic liquids are salts in liquid form, or a salt solution. They are good conductors of electricity."The key, here, is that we used a paramagnetic ionic liquid, a new type of ionic liquid we synthesized ours...
Physicists discover super stable tri-anion particle

Physicists discover super stable tri-anion particle

Science
Sept. 18 (UPI) -- Researchers at Virginia Commonwealth University have discovered a new tri-anion particle, a type of particle with three more electrons than protons.The new particle is extremely stable and its discovery apply to a variety of applications in the fields of physics and chemistry. The imbalance between electrons and protons on all other tri-anions makes the particle inherently unstable.Tri-anion particles can often disrupt chemical reactions, as they refuse to take on any more electrons.Researchers discovered the particle through a computer middle. Scientists built the model to prove a stable tri-anion particle was theoretical property."This is very important in this field, nobody has ever found such a tri-anion," Dr. Puru Jena, a physics professor at VCU, said in a news rele...
Physicists find new particle with a double dose of charm

Physicists find new particle with a double dose of charm

Technology
Scientists have found an extra charming new subatomic particle that they hope will help further explain a key force that binds matter together. Physicists at the Large Hadron Collider in Europe announced Thursday the fleeting discovery of a long theorized but never-before-seen type of baryon. Baryons are subatomic particles made up of quarks. Protons and neutrons are the most common baryons. Quarks are even smaller particles that come in six types, two common types that are light and four heavier types. The high-speed collisions at the world's biggest atom smasher created for a fraction of a second a baryon particle called Xi cc, said Oxford physicist Guy Wilkinson, who is part of the experiment. The particle has two heavy quarks — both of a type that are called "charm"— and a light one. ...
