Quantitatively elucidating the effect of supercritical drying conditions on silica aerogels’ structure and chemical composition

Results in Surfaces and Interfaces
Aerogels, renowned for their exceptional thermal insulation, are widely used in the space industry and sustainable applications. However, their large specific surface area makes them highly sensitive to environmental conditions, such as relative humidity,

Performance of the Two Aerogel Cherenkov Detectors of the JLab Hall A Hadron Spectrometer

, 2008
We report on the design and commissioning of two silica aerogel Cherenkov detectors with different refractive indices. In particular, extraordinary performance in terms of the number of detected photoelectrons was achieved through an appropriate choice ...

Varying Synthesis Parameters of Potato Starch Aerogel for Aerospace Applications

Gels
Aerogels have the potential for usage in many daily and high-tech aerospace applications. Silica aerogels are fragile, while organic aerogels are much tougher, but they are both generally synthesized using toxic solvents.

Sky-mimesis, a path from nanotechnology to visual arts: A review of art applications of aerogels

Micro and Nano Engineering
Interdisciplinary research between science and art is becoming more active, because it stimulates the both fields with far different viewpoints. In the field of aerogels, exceptionally low-density porous materials, the authors have been promoting ...

Catalytically Active SiO₂ Aerogels Comprising Chelate Complexes of Palladium

Molecules
A series of silica-based aerogels comprising novel bifunctional chelating ligands was prepared. To produce target aerogels, two aminosilanes, namely (3-aminopropyl)trimethoxysilane (APTMS) and N-(2-aminoethyl)-3-aminopropyltrimethoxysilane (AEAPTMS ...
