An easy, scalable and direct method for synthesizing graphene in silicon microelectronics
Researchers have developed an easy and microelectronics-compatible method to grow graphene and have successfully synthesized wafer-scale (four inches in diameter), high-quality, multi-layer graphene on silicon substrates. The method is based on an ion implantation technique, a process in which ions are accelerated under an electrical field and smashed into a semiconductor.
Degrading BPA with visible light and a new hybrid nanoparticle photocatalyst
Adding silver and reduced graphene oxide to titanium dioxide nanoparticles improves their photocatalytic activity.
U.S. Navy eyes nanotechnology for ultimate power control system
The Office of Naval Research has awarded engineers an $800,000 grant to develop narrow strips of graphene called nanoribbons that may someday revolutionize how power is controlled in ships, smartphones and other electronic devices.
Spintronics: Organic molecules stabilizing magnetism
Organic molecules allow producing printable electronics and solar cells with extraordinary properties. In spintronics, too, molecules open up the unexpected possibility of controlling the magnetism of materials and, thus, the spin of the flowing electrons. According to a new report, a thin layer of organic molecules can stabilize the magnetic orientation of a cobalt surface.
Fluorescent material reveals how cells grow
Fibre from a semiconducting polymer, developed for solar cells, is an excellent support material for the growth of new human tissue. Researchers have shown that the fibre glows, which makes it possible to follow the growth of the cells inside living tissue.
Self-assembled aromatic molecular stacks, towards modular molecular electronic components
Researchers describe the electron-transport properties of aromatic stacks aligned in a self-assembled cage, using a scanning tunneling microscope (STM) based break-junction method.
