Material characteristics and applications of transparent amorphous oxide semiconductors
T. Kamiya, H. Hosono
Transparent amorphous oxide semiconductors have unique electron transport properties that are not seen in conventional amorphous semiconductors, and are attractive for use in thin-film transistors as a basis for the next generation of flat-panel displays. Research into these materials has revealed some of the physical features responsible for their useful electronic structures. |

The design and utility of polymer-stabilized iron-oxide nanoparticles for nanomedicine applications
C. Boyer, M. R. Whittaker, V. Bulmus, J. Liu, T. P. Davis
Superparamagnetic iron-oxide nanoparticles have a range of specific applications in the emerging field of nanomedicine, including their use in drug delivery and as contrast agents in magnetic resonance imaging. The addition of a polymer layer stabilizes these nanoparticles for biological applications, and allows functionalization for the encapsulation of therapeutic agents. |

Zero-gap materials for future spintronics, electronics and optics
X. L. Wang, S. X. Dou, C. Zhang
Materials having a zero-energy band gap exhibit some fascinating and superior electronic properties compared to materials with a non-zero energy gap. As the details of the electronic and spin structures of these materials become clearer, so do the range of potential applications, from spintronics and electronics, to optics and sensors. |
