Abstract
Carbon nanotubes are attracting a lot of attention as the building blocks of nanotechnology. But nanotubes are difficult to align and process into useful materials. In his Perspective, [Dzenis][1] discusses the process of nanofiber electrospinning, in which continuous threads of polymers or ceramic precursors are emitted from a liquid surface as thin jets. These continuous nanofibers may offer an alternative for new nanotechnology applications. [1]: http://www.sciencemag.org/cgi/content/full/304/5679/1917
