    The present invention involves alewives of highly aligned single-wall carbon nanotubes (SWNT), process for making the same and compositions thereof. The present invention provides a method for effectively making carbon alewives, which are discrete, acicular-shaped aggregates of aligned single-wall carbon nanotubes and resemble the Atlantic fish of the same name. Single-wall carbon nanotube alewives can be conveniently dispersed in materials such as polymers, ceramics, metals, metal oxides and liquids. The process for preparing the alewives comprises mixing single-wall carbon nanotubes with 100% sulfuric acid or a superacid, heating and stirring, and slowly introducing water into the single-wall carbon nanotube/acid mixture to form the alewives. The alewives can be recovered, washed and dried. The properties of the single-wall carbon nanotubes are retained in the alewives.
