摘要:
A process of producing a composite having carbon nanotubes is described where the carbon nanotube formation process of producing carbon nanotubes includes controlled heating of plant fiber materials in an oxygen-limited atmosphere. The plant fiber materials may be heated either cyclically or by rapid heating to produce the carbon nanotubes.

A burial vault assembly for displaying a vault cover and placing the cover onto a vault base. The assembly has a support structure with a first and second rail secured to the top of a support structure. Each rail has a first portion and a second portion that extends towards the seating area of the burial site and at a downward angle from the first portion. Each rail additionally at the end of its second portion has a stopping element. Thus, a burial cover is moveable along the first and second rails from a sealing position to a display position wherein the vault cover is stopped in place by the stopping element.
