Researchers have experimentally realized the quantum anomalous Hall effect in a multilayered insulator, essentially producing a multilane highway for the transport of electrons that could increase the speed and efficiency of information transfer without energy loss.
Researchers have developed tiny 'Janus balls' that show their colored side under a magnetic field. These microparticles could be useful in inks for anti-counterfeiting tags, which could be verified with an ordinary magnet, the researchers say.
Printing with an ink-jet printer is part of daily life, but the same technology finds more complex applications in electronics and in protein separation. These applications rely on the quality of the printing process which depends on the flow of the 'ink' through narrow pores.
Researchers have created a new carbon-based electrical device by using an ionic gel made of a conductive polymer. This work may lead to cheaper and more reliable flexible printable electronics.
An international research team has demonstrated a novel process to modify the structure and properties of graphene. This chemical reaction, known as photocycloaddition, modifies the bonds between atoms using ultraviolet (UV) light.
