COVER Molybdenum dioxide nanowires (300 nanometers in diameter) were electrodeposited from an aqueous solution onto this graphite surface, where each nanowire is formed at a preexisting defect. After reduction in hydrogen gas, metallic molybdenum nanowires are obtained. These nanowires can then be embedded in a polystyrene film and lifted off the surface intact, creating the potential for applications in microelectronics and chemical sensors. See page 2120.
