Researchers discover how molecules in ancient glass rearrange and recombine with minerals over centuries to form a patina of photonic crystals – ordered arrangements of atoms that filter and reflect light in very specific ways – an analog of materials used in communications, lasers and solar cells
Bioengineers have found a way to program the size and shape of virus particles by combining viral protein building blocks and templates made from DNA. The resulting nanostructures could have applications in vaccine development and transporting drugs inside the body.
Researchers at Cornell have developed nanostructures that enable record-breaking conversion of laser pulses into high-harmonic generation, paving the way for new scientific tools for high-resolution imaging.
As antibiotic-resistant bacteria become more prevalent, silver has seen steep growth in its use in things like antibacterial coatings. Still, a better understanding can provide clues on how to best apply it. In Chemical Physics Reviews, researchers monitored the interaction of silver nanoparticles with a nearby E. coli culture and found the silver undergoes several dramatic changes. Most notably, the E. coli cells caused substantial transformations in the size and shape of the silver particles.
Scientists improved the performance of a battery electrode material with a unique flower-shaped nanostructure.
Researchers have been working for decades on improving the anti-icing performance of functional surfaces and work published in AIP Advances investigates a unique nanostructure, modeled on moth eyes, that has anti-icing properties. Moth eyes are of interest because they have a distinct ice-phobic and transparent surface. The researchers fabricated the moth eye nanostructure on a quartz substrate that was covered with a paraffin layer to isolate it from a cold and humid environment.
