Fruits of the forest: A desktop reactor rapidly grows forests of aligned carbon nanotubes (CNTs) to heights of many millimeters by atmospheric-pressure chemical vapor deposition (see picture). This low-cost apparatus achieves the reaction temperature by resistive heating of a suspended silicon platform, and achieves a 20-fold increase in CNT growth rate by thermal pretreatment of the reactant mixture. The film thickness is monitored in situ.
