A simple sol-gel synthesis of superconducting MgB2 nanowires

Superconducting MgB2 nanowires have been synthesized to a very high yield by a simple soft-chemical approach combining sol-gel chemistry and pyrolysis techniques (see main image in the figure; scale bar: 10 gm). The long thin nanowires show a superconducting transition temperature, T., of ca. 39 K, as shown in the magnetization curve in the inset of the figure.
