Rice University team creates 3D objects from graphene foam

Rice University scientists have developed a simple way to create conductive, 3D objects made of graphene foam. The resulting objects may offer new possibilities for energy storage and flexible electronic sensor applications, according to Rice chemist Prof. James...

Researchers use graphene to increase the sensitivity of diagnostic devices

Researchers at the University of Pennsylvania have used graphene to increase the sensitivity of diagnostic devices, in particular those used to monitor and treat HIV. The team combined a trick of DNA engineering which involves an engineered piece of DNA called a...

Graphene and silver combined to create photodetectors with increased ability to detect UV light

Researchers from the Indian Institute of Science (IISc), the Max Planck Institute for Intelligent Systems in Germany and the University of Stuttgart, Germany have developed a novel silver nanoparticle-graphene hybrid photodetector device with an increased ability to...

The dispute over the origins of terahertz photoresponse in graphene results in a draw

Researchers at the Russia-based MIPT, MSPU and the University of Manchester revealed the mechanisms leading to photocurrent in graphene under terahertz radiation. The paper is said to put an end to a long-lasting debate about the origins of direct current in graphene...

Russian team develops copper-graphene oxide biosensor chips with excellent sensitivity

Researchers from the Russia-based Moscow Institute of Physics and Technology (‘MIPT’) have developed biosensor chips of unprecedented sensitivity, which are based on copper combined with graphene oxide instead of the conventionally used gold. In addition...
