Surface and porosity of nanocrystalline boehmite xerogels [PDF]
Journal of Colloid and Interface Science, 2005 Boehmite xerogels are prepared by hydrolysis of Al(OC4H9)3 followed by peptization with HNO3 (H+/Al = 0, 0.07, 0.2). XRD and TEM show that these gels are made of nanosized crystals (5–9 nm in width and 3 nm thick).

Wood xerogel for fabrication of high-performance transparent wood
Nature Communications, 2023 Optically transparent wood has been fabricated by structure-retaining delignification of wood and subsequent infiltration of thermo- or photocurable polymer resins but still limited by the intrinsic low mesopore volume of the delignified wood.

Superfast Synthesis of Carbon Xerogels
ACS Omega, 2023 Carbon xerogels (CXs) provide unique opportunities for numerous applications in the areas of adsorption, separation, insulation, catalysis, and electrochemistry, but their use is hampered by time- and energy-intensive synthesis protocols. Synthesis protocols may require several days or more. Here, we report the synthesis of CXs requiring only 5 h using
