For Future Superconductors, a Little Bit of Lithium May Do Hydrogen a Lot of Good

Metallic hydrogen is predicted to be a high-temperature superconductor. A superconductor is a state of matter where electrons, and thus electricity, can flow indefinitely and without resistance.

In a paper published this week in the online edition of the Proceedings of the National Academy of Sciences, a team of scientists from Cornell University and the State University of New York at Stony Brook announce a theoretical study that predicts the metallization of hydrogen-rich mixtures at significantly lower pressures. more

Michael Hall, a graduate student in LASSP's Single Molecule Biophysics Lab, can actually "unzip" the two strands of a DNA molecule using a procedure called optical trapping. To do this, he focuses a laser on a micron-sized polystyrene bead. Light going through the bead changes direction, forcing the bead in the opposite direction. The result is that the bead remains in the center of the beam of light, trapped in the optical trap. Michael can attach these beads to tiny ...
