 I. INTRODUCTIONHE expression "nanotechnology" has developed throughout the years by means of conceptual drift to the term "anything smaller than microtechnology," for example, nanopowders, and different things that are nanoscale in size, but not alluding to mechanisms that have been deliberately constructed from nanoscale components. This development version of the term is more properly called "Nanoscale Bulk Technology," whereas the original meaning is

“…The sol–gel process is one of the techniques for synthesizing silica gel, and the dried gel may present a variety of microstructures, depending on the synthesis parameters and drying conditions . The challenge to produce very low-density products led to the synthesis of silica aerogels that are among the lightest and best thermal insulating materials known . All types of silica, from dense glass to aerogels, can be classified as brittle materials .…”

Structure and Properties of Cork–Silica Xerogel Nanocomposites: Influence of the Cork Content

2018

Environmentally friendly nanocomposites were synthesized from a silica precursor and cork under mild conditions and dried at atmospheric pressure. Because of the covalent bonding between the components, these CorSil nanocomposites are homogeneous, light (apparent density in the range 360−750 kg m −3 ), machinable, with the Shore D hardness up to 67 and compressive strength up to 22.6 MPa. These properties place them as good replacements for wood, other natural products, and thermoplastic polymers, with the advantage of being flameretardant. The influence of the cork content and grain size on the structure, porosity, and mechanical properties of the nanocomposites was studied using infrared spectroscopy, sorption isotherms, compressive strength, and Shore D hardness measurements.

“…Metal oxide aerogels have been more challenging to synthesize and are less well understood than the silica type [2] , especially when these aerogels have been formed via catalyzed hydrolysis and condensation reaction of metal alkoxide precursors [3, 4] . Unfortunately, the lack of suitable metal alkoxides and their associated handling issues has restricted the production of metal oxide aerogels.…”

“…Unfortunately, the lack of suitable metal alkoxides and their associated handling issues has restricted the production of metal oxide aerogels. However, the epoxide-assisted gelation approach expanded the production of metal oxide aerogels and the range of possible salt precursors that could be used [2] .

Aerogel materials manufactured from metal oxides have been used as components in numerous high-energy density physics targets. These aerogels have been identified to be used as a future target material in the AWE fielded campaigns at the US National Ignition Facility. A wide variety of metal oxide aerogels are required for future campaigns and therefore a versatile manufacturing route is sought; as such, an epoxide-assisted sol-gel route was investigated. Under the European Union Registration, Evaluation, Authorization and Restriction of Chemicals legislation, the most commonly used epoxide, propylene oxide, is recognized as a substance of very high concern (SVHC). This work sought to investigate suitable alternative epoxides for use in target manufacture. The outcome was the identification of synthesis routes for stable metal oxide aerogel monoliths using epoxides not subject to the above restrictions.
