Preparation of Silica Aerogels by Ambient Pressure Drying without Causing Equipment Corrosion [PDF]

Molecules, 2018
The silica aerogels were prepared via a sol-gel technique and ambient pressure drying by using industrial solid wastes, dislodged sludges, as raw materials. A strategy was put forward to reduce the corrosion of equipment during the drying procedure.

Hydrophilic and Hydrophobic: Modified GeO₂ Aerogels by Ambient Pressure Drying [PDF]

Nanomaterials
An ever-increasing number of applications of oxide aerogels places a high demand on wettability-tuning techniques. This work explores the possibility to cheaply prepare GeO2 aerogels with controlled wettability by an ambient pressure drying (APD) method.

Solvent Cavitation during Ambient Pressure Drying of Silica Aerogels. [PDF]

Langmuir
Ambient-pressure drying of silica gels stands out as an economical and accessible process for producing monolithic silica aerogels. Gels experience significant deformations during drying due to the capillary pressure generated at the liquid–vapor interface in submicron pores.

Morphology control of nickel nanoparticles prepared in situ within silica aerogels produced by novel ambient pressure drying [PDF]

Scientific Reports, 2020
Silica aerogels are low density solids with high surface area and high porosity which are ideal supports for catalyst materials. The main challenge in aerogel production is the drying process, which must remove liquid from the pores of the wet gel while ...

Effect of Drying Control Agent on Physicochemical and Thermal Properties of Silica Aerogel Derived via Ambient Pressure Drying Process

Energies, 2023
This paper presents the effect of drying control agents on the physicochemical and thermal properties of hydrophobic silica aerogels derived via the ambient pressure drying (APD) method by a surface silylation using a TMCS/n-hexane mixture.

Springback effect and structural features during the drying of silica aerogels tracked by in-situ synchrotron X-ray scattering

Scientific Reports, 2022
The springback effect during ambient pressure drying of aerogels is an interesting structural phenomenon, consisting of a severe shrinkage followed by almost complete re-expansion.
