New tannin-lignin aerogels

Author(s): , , , , , ,

Tannin and lignin are organic materials that are more cost-effective than synthetic, non-renewable phenolic compounds. In this paper, tannin-lignin-formaldehyde (TLF) composites were used to synthesize thermally insulative mesoporous aerogels. A ...

Influence of environmental factors on the adsorption capacity and thermal conductivity of silica nano-porous materials 

Author(s): , , , , ,

Aerogels have a wide range of properties that make them effective thermal insulators. However, these properties are lost when the materials absorb too much water. The goal of this experiment ...

Ambient pressure dried shape-controllable sodium silicate based composite silica aerogel monoliths

Author(s): , , , , ,

The preparation process of silica aerogels has commonly involved a dangerous supercritical drying step, so work has been done to eliminate this step. This paper discusses the preparation of composite ...
