Submerged SNO in the presence of electric bias undergoes a phase change by intercalating protons in the lattice structure.
Sense like a shark: Saltwater-submersible nickelate film

Argonne researchers have developed a new sensor technology that detects minute changes in electromagnetic fields in much the same way sharks sense their prey.

Depiction of the peptide amphiphile, PA (A) and the zinc porphyrin, ZnP (B, shown as both sticks and spheres) that comprise the doped nanofibers. Sheets are shown for high doping ratios of ZnP:PA (C,E,G) and low doping ratios (D,F,H). C and D highlight the relative ZnP packing and E and F illustrate the variation in ZnP spacing. G and H highlight the fiber cross sections.
A new infrastructure: Moving energy on peptide nanofibers

This study links a controllable parameter to improved light-harvesting capabilities.
