A new method for preparing tannin-based foams

Author(s): , , , ,

The authors present a novel method for the preparation of highly porous tannin-based meringues by shear mechanical mixing of tannin, hexamine, and Kolliphore® ELP in water. The liquid foam was ...

Reduction of shrinkage and brittleness for resorcinol-formaldehyde aerogels by means of a pH-controlled sol-gel process 

Author(s): , ,

This article investigates how the thermal conductivity of a resorcinol-formaldehyde aerogels varies with increasing resorcinol (R) to water (W) ratios. The thermal conductivity was measured using the Hot disk transient ...

Preparation and characterization of ultralow density silica aerogels by acetonitrile supercritical drying

Author(s): , , ,

In this study, ultralow density silica aerogels were synthesized and their thermal conductivities were tested to determine how supercritical drying affected the samples. A Hot-Disk TPS2500 measured the thermal conductivity ...

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 ...
