Boron carbide is a highly refractory material that is of great interest for both its structural and electronic properties. Of particular importance are its high-temperature stability, high hardness, high cross section for neutron capture, and excellent high-temperature thermoelectric properties. This combination of properties gives rise to numerous applications, including uses as an abrasive wear-resistant material, ceramic armor, a neutron moderator in nuclear reactors, and, potentially, for power generation in deep-space flight applications. In this communication , the authors report a simple, straightforward method for the generation of aligned, monodispersed boron carbide nanofibers based on the use of the porous alumina templating technique in combination with a new single-source molecular precursor.
