Add water and dishwashing liquid, and mix at high speed. Congratulations, you just made the wonder material graphene. This surprisingly simple recipe is now the easiest way to mass-produce pure graphene – sheets of carbon just one atom thick. The material has been predicted to , based on its unusual electrical and thermal properties. "There are companies producing graphene at much higher rates, but the quality is not exceptional," says Jonathan Coleman of Trinity College Dublin in Ireland. Coleman's team was contracted by Thomas Swan, a chemicals firm based in Consett, UK, to come up with something better. Carbon smoothie The team put graphite powder and a solvent fluid in a laboratory mixer and set it spinning.
"If you are using a blender, why use a fancy expensive surfactant? Still, Coleman says you may not want to try this at home. "It is a fun experiment, but it wouldn't get you very far," says Colman.

O projeto KOGNIT tem como atividades base a criação e desenvolvimento de materiais e conteúdos pedagógicos que promovam a divulgação e o despertar do interesse para a Ciência e Tecnologia entre crianças com idades compreendidas entre os 6 e 12 anos.
Uma parte significativa do nosso dia é passada interagindo com dispositivos tecnológicos, no entanto a maioria de nós não sabe como funcionam, tão pouco a tecnologia que lhes deu origem ou como são produzidos. Pese embora toda a interatividade que estes dispositivos oferecem, ficamos limitados a um usufruto passivo da tecnologia. No projeto KOGNIT acreditamos que o aceso à ciência e tecnologia deve ser universal e começar desde a mais tenra idade. Para tal criamos conteúdos e materiais pedagógicos que fomentam entre as crianças a descoberta da ciência e da tecnologia, de uma forma intuitiva, segura e universal, sem exclusões (de género, de necessidades especiais, de idade). The Free Universal Construction Kit. Ever wanted to connect your Legos and Tinkertoys together? Now you can — and much more. Announcing the Free Universal Construction Kit: a set of adapters for complete interoperability between 10 popular construction toys.
Fig. 1. The Free Universal Construction Kit. Overview Video by Riley Harmon for F.A.T. Lab + Sy-Lab. F.A.T. The Free Universal Construction Kit offers adapters between Lego, Duplo, Fischertechnik, Gears! Motivation Our kids are already doing it! Opening doors to new creative worlds is one major reason we created the Free Universal Construction Kit. The Kit offers a “best of all worlds” approach to play and learning that combines the advantages of each toy system. Finally, in producing the Free Universal Construction Kit, we hope to demonstrate a model of reverse engineering as a civic activity: a creative process in which anyone can develop the necessary pieces to bridge the limitations presented by mass-produced commercial artifacts.
