Electric Eel-Inspired Device Reaches 110 Volts: This photo depicts the printed, high voltage implementation of the artificial electric organ. A 3-D bioprinter was used to deposit arrays of gel precursor droplets onto plastic substrates, which were then cured with a UV light to convert them into solid gels. Alternating high-salinity and low-salinity gels (red and blue gels, respectively) were printed onto one substrate, and alternating cation-selective and anion-selective gels (green and yellow gels, respectively) were printed onto a second substrate. When overlaid, these gels connect to form a conductive pathway of 612 tetrameric gel cells that can be used to generate up to 110 volts. Credit: Anirvan Guha and Thomas Schroeder

Under UV light, the SLAO phosphor emits either green-yellow or blue light depending on the chemical activator mixed in. Credit: David Baillot/UC San Diego Jacobs School of Engineering

The aluminum plates were attached to the topological insulator using platinum. The picture (scale bar: 200?nm) shows one of the devices used in the experiment. Because of the stress, induced by various cool downs, a clear buckling feature appears in the nanogap of the device. This modification is causing the characteristics of the superconducting pairs of electron to vary in different directions, a signature of unconventional superconductivity.
