The potential applications for flexible plastic electronics are enormous -- from electronic books to radio frequency identification (RFID) tags to electronics for cell phones, personal digital assistants (PDAs) and laptop computers -- but certain technological hurdles must be overcome before we see such widespread use.
Now a Northwestern University team of materials chemists report a breakthrough in the race to find the right materials for producing cost-effective, high-performance plastic electronics. The findings appear in the Proceedings of the National Academy of Sciences (PNAS).
The team, led by Tobin J. Marks, Vladimir N. Ipatieff Professor of Chemistry and professor of materials science and engineering, has designed organic molecules that self assemble into an ultra-thin layer (less than six nanometers thick) for use in the dielectric, or nonconducting, component of a transistor. Their tailored molecular components reduce both operating voltage and power consumption in organic thin-film transistor (OTFT) structures, making low-power consumption OTFTs a reality.

It’s All in the Mix: Jülich Researchers are Developing Fast-Charging Solid-State Batteries
20.08.2018 | Forschungszentrum Jülich
There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.
The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...
