Liquid crystals, discovered more than 125 years ago, are at work behind the screens of TV and computer monitors, clocks, watches and most other electronics displays, and scientists are still discovering new twists—and bends—in their molecular makeup. Liquid crystals are an exotic state of matter that flows like a fluid but in which the molecules […]

Researchers 3D print ultralight supercapacitors
For the first time ever, scientists at Lawrence Livermore National Laboratory and UC Santa Cruz have successfully 3D-printed supercapacitors using an ultra-lightweight graphene aerogel, opening the door to novel, unconstrained designs of highly efficient energy storage systems for smartphones, wearables, implantable devices, electric cars and wireless sensors. Using a 3D-printing process called direct-ink writing […]
