A hybrid insulation material comprises of porous ceramic substrate material impregnated with nanoporous material and method of making the same is the topic of this invention. The porous substrate material has bulk density ranging from 6 to 20 lb/ft and is composed of about 60 to 80 wt % silica (SiO ) 20 to 40 wt % alumina (Al O ) fibers, and with about 0.1 to 1.0 wt % boron-containing constituent as the sintering agent. The nanoporous material has density ranging from 1.0 to 10 lb/ft and is either fully or partially impregnated into the substrate to block the pores, resulting in substantial reduction in conduction via radiation and convention. The nanoporous material used to impregnate the fiber substrate is preferably formed from a precursor of alkoxysilane, alcohol, water, and an acid or base catalyst for silica aerogels, and from a precursor of aluminum alkoxide, alcohol, water, and an acid or base catalyst for alumina aerogels.

The use in diagnostic imaging, in particular X-ray, MRI, ultrasound and scintigraphy, of contrast agents comprising bismuth clusters and/or organic bismuth compounds, and contrast media containing such bismuth compounds. The bismuth compounds are also useful in therapy, in particular as antimicrobial agents and antiulcer agents. Novel bismuth compounds are also disclosed.

This pertains to the general field of gels, foams, and aerogels, particularly, to low density open cell organic foams and low density open cell carbon foams, and methods for preparing them. These low density open cell organic foams are derived from organic gels which may be prepared from hydroxylated benzenes (such as phenol, catechol, resorcinol, hydroquinone, and phloroglucinol) and aldehydes (such as formaldehyde and furfural) using lower than conventional catalyst concentrations (e.g, an R/C value of greater than about 1000, yielding an initial room temperature pH typically lower than about 6.0). These organic foams are characterized by relatively large particle and pore sizes, high porosity, and high surface area. Low density open cell carbon foams derived from such organic foams are also shown, as are methods for preparing same. These carbon foams are also characterized by relatively large particle and pore sizes, high porosity, high surface area, and high electrical capacitance. Low density open cell carbon foam/carbon substrate composites and methods for preparing them are also shown.

Transparent, monolithic metal oxide aerogels of varying densities are produced using a method in which a metal alkoxide solution and a catalyst solution are prepared separately and reacted. The resulting hydrolyzed-condensed colloidal solution is gelled, and the wet gel is contained within a sealed, but gas permeable, containment vessel during supercritical extraction of the solvent. The present invention is especially advantageous for making metal oxides other than silica that are prone to forming opaque, cracked aerogels.
