High-Quality Helium Crystals Show Supersolid Behavior
Microprinting Technique for Patterning Single Molecules
credit: Paul Weiss lab, Penn State Microcontact Insertion Printing Left: Single molecules are inserted into a preexisting layer in microscopic regions that are defined by a patterned elastomeric stamp. Right: Complex and overlapping chemical patterns can be fabricated employing multiple stamping steps. (scanning electron micrograph, field of view 90 µm x 90 µm)
Taking Nanolithography Beyond Semiconductors
A new technique of chemical patterning developed at Penn State combines conventional lithography with molecular self-assembly for the creation of multifunctional surfaces.
Ultraviolet Light Reveals Secrets of Nanoscale Electronic Materials
In this diagonally striped picture, the distance between each line is about 0.4 nanometers and each of the bands is several nanometers.
Research Paper Illuminates How Light Pushes Atoms
A pencil-like laser beam can be made by intersecting two infinitely wide light waves at a small angle. "You might think that an atom would absorb a photon randomly from only one of the beams," as depicted in the section labeled a), "but this paper shows that the atom recoils with a speed that is less than it would get from the momentum of either of the infinitely wide photons, with no sideways recoil," as depicted in b).
Penn State Researchers Look Beyond the Birth of the Universe
The figure represents our expanding universe as the right branch of the arc.
