Sentences with phrase «studies of single atom»

Their methodology and findings can impact a range of fields from fundamental studies of single atom and single molecule magnetism to the design of spintronic device architectures.

Not exact matches

The most widely studied set of quantum numbers is that for a single electron in an atom: not only because it is useful in chemistry, being the basic notion behind the periodic table, valence (chemistry) and a host of other properties, but also because it is a solvable and realistic problem, and, as such, finds widespread use in textbooks.

In a combined experimental and theoretical study on ultrafast excitation of atoms in intense short pulse laser fields scientists of the Max Born Institute succeeded to show that the prevailing and seemingly disparate intuitive pictures usually used to describe interaction of atoms with intense laser fields can be ascribed to a single nonlinear process.

For the study, published in the journal Nature Physics, the Kaiserslautern team around Professor Widera (Department of Physics and State Research Center OPTIMAS) developed a novel model system: A single atom is cooled by lasers near to absolute zero temperature and trapped by light within a near - perfect vacuum.

In the study, the authors describe a new chemical reaction that converts simple starting materials into architecturally complex molecules (a collection of atoms bonded to one another) called «decalins» in a single step.

Based on the results from the studies at Harvard, NSLS - II, CFN, and additional institutions, the scientists discovered single nickel atoms catalyzed the CO2 conversion reaction with a maximal of 97 percent efficiency.

However, the chemistry of dubnium had been studied previously, so the team was able to identify that final single atom in the decay chain by chemical means before it fell apart.

«By reversing the cycle, we could even use the device as a single atom refrigerator and employ it to cool nano systems coupled to it,» explained Johannes Roßnagel, first author of the study.

This achievement, reported in a paper published today in Nature Communications, will enable scientists to use traditional surface - science tools — such as x-ray photoelectron and infrared reflection absorption spectroscopy — to perform detailed studies of single gas atoms in confinement.

«Our computer simulations solved this dilemma, showing that the particles on the steps are reduced to single atoms» adds Matteo Farnesi Camellone (CNR - IOM), another author of the study.

«The atom - trapping technique should be broadly applicable for preparing single - atom catalysts,» said Abhaya Datye, a distinguished regents» professor of chemical and biological engineering at UNM who led the study.

Indeed, the team is expanding their study to the properties of the nearly ubiquitous hydronium and methyl groups, which contain a single oxygen or carbon atom and three hydrogen atoms.
