Beating Radiation with SANDS

Scientists at Northwestern University have reportedly developed a radiation-retardant transistor that is also printable and self-assembling.

The transistors are based on a dielectric called SANDs (self-assembling nanodielectrics) and are created via a dipping process which forms thin films of self-assembled molecules.

Prototypes have been placed outside the International Space Station, where they will be exposed to space radiation for a year.

The researchers feel the novel transistors could be used in transparent displays or flexible electronics.
