  • Extreme synthesis of crystalline aerogel materials from amorphous aerogel precursors
    Patent number: 11718787
    Abstract: In one embodiment, a composition of matter includes a crystalline porous structure having a density in a range from about 30 to about 50 mg/cm3. In another embodiment, a kit includes an amorphous, porous material, an inert pressure medium, a heating source, and a sample chamber configured to withstand an applied pressure of at least about 20 GPa. Other aspects and embodiments of the present invention will become apparent from the following detailed description, which, when taken in conjunction with the drawings, illustrate by way of example the principles of the invention.

  • Extreme synthesis of crystalline aerogel materials from amorphous aerogel precursors
    Patent number: 10479933
    Abstract: A method includes positioning a porous structure in a pressure cell; injecting an inert pressure medium within the pressure cell; and pressurizing the pressure cell to a pressure that thermodynamically favors a crystalline phase of the porous structure over an amorphous phase of the porous structure to transition the amorphous phase of the porous structure into the crystalline phase of the porous structure.

  • EXTREME SYNTHESIS OF CRYSTALLINE AEROGEL MATERIALS FROM AMORPHOUS AEROGEL PRECURSORS
    Publication number: 20110129614
    Abstract: In one embodiment, a system includes a pressure cell adapted for enclosing a porous structure; an inert pressure medium within the pressure cell; and a heat source for heating the porous structure. In another embodiment, a composition of matter includes a crystalline porous structure having a density of about 30 to about 50 mg/cm3. A method according to one embodiment includes positioning an amorphous porous structure in a pressure cell; injecting an inert pressure medium within the pressure cell; and pressurizing the pressure cell to a pressure that thermodynamically favors a crystalline phase of the porous structure over an amorphous phase of the porous structure to transition the amorphous porous structure into a crystalline porous structure. Additional embodiments are also presented.
