Dynamics of dark and bright excitons

By varying the time between the exciton-generating pump pulse and the extreme ultraviolet pulse that kicked out the electrons, the scientists were able to construct a video showing how dark excitons (red) and bright excitons (blue) changed over time.

To Buckle or Not to Buckle

Testing the stability of cylindrical tube made from 15,360 hexagonally packed magnetic balls (192 rings, each made up of 80 balls). A high-speed camera recording reveals crumpling at the base of the cylindrical tube, reminiscent of paper-like crumpling, when it loses stability from shaking.

The mechanophore glows more intensely as the stretching increases.

The polymer material is stretched with an increasing force resulting in a corresponding brighter emission of light from the mechanophore (here under UV light and with false colors). The graph shows the intensity of the emitted light following punctual increases in the stretching force applied to the polymer.

Math Meets Art: Möbius Kaleidocycles

Dr. Johannes Schönke and Prof. Eliot Fried of the OIST Mathematics, Mechanics, and Materials Unit have introduced a new class of kaleidocycles into the world. They call them Möbius Kaleidocycles because they resemble the famous Möbius band, a geometrical object with a characteristic topology. These mystifying objects can be turned inside-out continuously and have unique mathematical properties. While classical kaleidocycles typically have six hinges, the new class of kaleidocycles can have seven or more. Not only are these objects beautiful to see, but they could also have very practical applications in a variety of fields.
