Method of manufacturing spacers for pipe-in-pipe systems and spacer for a pipe-in-pipe structure

A method manufacturing a spacer for a pipe-in-pipe system includes mixing aerogel particles with a polymer to form a mixture in which the particles are dispersed in the polymer. The resulting mixture is moulded and the polymer is solidified to form the spacer or a component of the spacer, in which the dispersed, particles are suspended in a matrix of the solidified polymer.

System and method for infusing nano-technology into production of physical storage containers
11936106 · 2024-03-19 ·

The present invention is directed to the production of shipping containers, computer server farm containers, and other forms of physical storage containers from a carbon nanotube-based fiber material with the potential application of other, non-carbon, nano-based materials containing various structures. Current materials used for shipping containers, computer server farm containers, and other forms of physical storage containers are heavier than the present invention and lack the ability to withstand high-intensity shock vibrations and other disturbances and are vulnerable to radiofrequency (RF) radiation. Instead of using metal, which is the currently preferred material used in the development of shipping containers, computer server farm containers, and other forms of physical storage containers, the present invention provides the use of a carbon nanotube-based material.
