High-resolution, full-color display devices like foldable mobile phones and ultrathin television sets use organic light-emitting diodes (OLEDs). Compared to other display technologies, OLEDs offer ...

Scientists created dye-based molecules that self-assemble into ring-shaped structures, mimicking nature's light-harvesting systems. These stacked rings allow electrons and energy to circulate freely, ...

Electricity can be easily converted into heat—every electric cooker does it. But is the opposite also possible? Can heat be converted into electricity—directly, without a steam turbine or similar ...

Flat, dye-like molecules with eight upright, pillar-shaped extensions self-assemble into pairs, interlocking like gears to form a tightly packed ring of 16 stacked layers. This structure allows charge ...
