Combined STM and MRI techniques resolve single atoms on a surface, providing potential for imaging larger molecules. Credit: Philip Willke et al. One of the quantum properties used to characterize ...

In her continuing search for clues to understanding structural biology underlying disease, University of Delaware chemist Tatyana Polenova analyzes, atom by atom, the structure of viruses and ...

AMES, Iowa – A tiny, solid sample of a drug, complete with active and inactive ingredients, spun at 50,000 revolutions per ...

Being able to manipulate and monitor single electrons in predesigned atomically-defined structures has been a long-standing goal for condensed matter physicists. A team led by Robert Wolkow of the ...

WEST LAFAYETTE, Ind. — The same technology behind MRI images of injury or disease also powers nuclear magnetic resonance (NMR) spectroscopy, which is used to analyze biological molecules for research ...

It's driving me nuts. Is the double bond constantly changing between all possibilities fast enough that it shortens the bond length for all, or are all the double bonds existing in all possible states ...

Oxidative damage is thought to underlie many age-related disorders of the eye, and can be caused by oxidative molecules as well as photooxidation from UV light. The risk of AMD increases with exposure ...

An international research team has taken a decisive step toward a new generation of atomic clocks. At the European XFEL X-ray laser, the researchers have created a much more precise pulse generator ...

Atomic clocks based on stimulated resonance of cesium 133 or rubidium atoms are the most accurate clocks in relatively widespread use (there’s one in each GPS satellite), but they’re costly and ...
