Noble Metal Aerogels

ACS Applied Materials & Interfaces, 2020
Noble metal-based nanomaterials have been a hot research topic during the past few decades. Particularly, self-assembled porous architectures have triggered tremendous interest. At the forefront of porous nanostructures, there exists a research endeavor of noble metal aerogels (NMAs), which are unique in terms of macroscopic assembly systems and three ...

Aerogels

Advanced Materials, 1991
Research News: Recently listed amongst the top ten scientific and technological developments, aerogels have found applications as traps for relativistic particles, in fire protection and in thermal insulation or acoustic impedance. The materials, which contain more air than gel, their synthesis, and other potential applications are described.

Organofunctional silica aerogels

Journal of Sol-Gel Science and Technology, 1997
Organically modified silica aerogels were prepared from mixtures of tetramethoxysilane (TMOS) and organofunctional alkoxysilanes RSi(OMe)3 with R = mercaptopropyl, diphenylphosphinoethyl and chloropropyl. The base catalyzed hydrolysis and condensation reactions, followed by supercritical drying with liquid carbon dioxide were investigated.

Cellulose–silica aerogels

Carbohydrate Polymers, 2015
Aerogels based on interpenetrated cellulose-silica networks were prepared and characterised. Wet coagulated cellulose was impregnated with silica phase, polyethoxydisiloxane, using two methods: (i) molecular diffusion and (ii) forced flow induced by pressure difference.

Monolithic Nanoporous Crystalline Aerogels

Macromolecular Rapid Communications, 2013
Monolithic aerogels can be easily obtained by drying physical gels formed by linear uncross‐linked polymers. Preparation methods, structure, and properties of these physically cross‐linked polymeric aerogels are reviewed, with particular emphasis to those whose cross‐linking knots are crystallites and, more in particular, crystallites exhibiting ...

Aerogels

2014
Aerogels were discovered in 1932 and since then their properties, in particular their high surface area, small pore size, transparency, low thermal conductivity and high pore volume have attracted attention for diverse applications. These applications include thermal insulation, catalyst supports, anti-reflectance coatings, composite materials such as ...

Preparation of V2O5 aerogels and aerogel coatings

Journal of Non-Crystalline Solids, 1992
Monolithic aerogels and aerogel coatings of hydrated V 2 O 5 , containing up to 10 mol% GeO 2 , were prepared from metal alkoxides by hydrolysis and autoclave drying. The porosity of the monolithic aerogels was > 90%. The aerogels consisted of microfibrous V 2 O 5 polymer.

Coherent Expanded-Aerogels

The Journal of Physical Chemistry, 1932
Abstract There are few topics in colloid chemistry that have experienced such extensive investigation as that of the structure of gels. Numerous hypotheses have been presented and supported by experimental data of one character or another. Certain aspects of gels have seemed to classify them as solid solutions, others as emulsions, while yet ...
