Abstract
Systems and methods for the formation of carbon-based nanostructures using large-scale active growth structures are generally described. In addition, systems and methods related to the formation of carbon-based nanostructures using basalt and/or titanium (e.g., elemental titanium) are generally described. The carbon-based nanostructures can be grown by exposing the large-scale active growth structures, basalt, and/or titanium to a set of conditions selected to cause formation of carbon-based nanostructures on (e.g., directly on) the large-scale active growth structure, basalt, and/or titanium. When basalt and/or titanium are used as all or part of an active growth structure, the basalt and/or titanium can be in any suitable form such as, for example, a planar or non-planar active growth structure (which can have, in some cases, a first cross-sectional dimension of at least about 1 mm) comprising basalt and/or titanium (e.g., a fiber comprising basalt and/or titanium) and/or particles (e.g., nanoparticles) comprising basalt and/or titanium.
