The ability to charge cellphones in seconds is one step closer after researchers at the University of Waterloo used nanotechnology to significantly improve energy-storage devices known as supercapacitors.
Lithium-ion batteries are used to power many things from mobile phones, laptops, tablets to electric cars. But they have some drawbacks, including limited energy storage capacity, low durability and long charging time.
OLED displays are very sensitive to oxygen and moisture, and the need to protect the displays is one of the major challenges of this next-generation display technology. First generation OLED displays were protected with a glass barrier, but glass is not easily flexible and so cannot be used in flexible OLEDs. Flexible OLEDs are today encapsulation with a thin-film encapsulation layer made from both organic and in-organic materials, and companies are searching for better OLED encapsulation technologies.
The University of Mississippi has established a new center to advance translational science and engineering of graphene-based technologies. The Center for Graphene Research and Innovation will focus on bridging the gap between university-based science and discovery and industry-led innovations and applications for graphene.
