An international team of researchers have devised an ultrafast tunable metamaterial based on gallium arsenide nanoparticles. The new optical metamaterial paves the way to ultrafast information transfer on the nanoscale.
Researchers report the development of nanoparticles that mimic the behavior of natural melanosomes, melanin-producing cell structures that protect our skin, eyes and other tissues from the harmful effects of ultraviolet radiation.
Researchers have shown record external quantum efficiencies for diodes based on organic red/NIR oligomers free from heavy/toxic metals and combining electron-withdrawing (A) moieties together with electron-donating (D) ones, in a previously poorly studied A-D-A motif.
Materials scientists have written the recipe on how to use an oddball enzyme to build new biomaterials out of DNA. The work provides instructions for researchers the world over to build self-assembling molecules for applications ranging from drug delivery to nanowires.
