A group of engineers working on a novel manufacturing technique at NASA`s Langley Research Center in Hampton, Va., have come up with a new twist on the popular old saying about dreaming and doing: "If you can slice it, we can build it."
That`s because layers mean everything to the environmentally-friendly construction process called Electron Beam [...]

When the University of Chicago`s David Mazziotti talks about chemistry, perhaps he is thinking about how the behavior of all of the electrons in a molecule can be anticipated from the behavior of just two of its electrons.
For 50 years theoretical chemists have puzzled over the problem of predicting many-electron chemistry with only two electrons, [...]

Like astronomers tweaking images to gain a more detailed glimpse of distant stars, physicists at the U.S. Department of Energy`s (DOE) Brookhaven National Laboratory have found ways to sharpen images of the energy spectra in high-temperature superconductors — materials that carry electrical current effortlessly when cooled below a certain temperature.
These new imaging methods confirm that [...]
