Silica aerogel; synthesis, properties and characterization
TL;DR: In this article, a review of research work and developments in synthesis, properties and characterization of silica aerogels is presented, with particular attention paid to drying, which is a critical step in aerogel synthesis and makes the production of this material more economical and commercial.
Journal ArticleDOI
Theory of Drying
TL;DR: In this paper, the authors examined the forces that produce shrinkage and the mechanisms responsible for transport of liquid, and a variety of strategies for avoiding fracture during drying were discussed, with the emphasis on the constant rate period (CRP) when the pores are full of liquid.

Toward aerogel based thermal superinsulation in buildings: A comprehensive review
TL;DR: Aerogel is a kind of synthetic porous material, in which the liquid component of the gel is replaced with a gas as mentioned in this paper, and it is considered as one of the most promising thermal insulating materials for building applications.

Techniques for the preservaation of three-dimensional structure in preparing specimens for the electron microscope†
TL;DR: In this paper, a method of sample preparation that reduces distortion and maintains 3D structure is described, where a droplet is placed on a formvar-coated screen and fix with osmic acid vapor.

Coherent Expanded-Aerogels
TL;DR: The two-phase structure of gels has been investigated extensively in colloid chemistry as discussed by the authors, and the results of diffusion experiments through gels, the fact that the electrical conductivity, refractive index, and vapor pressure before and after setting are identical, at least in certain cases, and the known facts of syneresis would seem to leave little room for doubt of the two phase nature of Gels in general.
