Hydrophobization of Monolithic Resorcinol-Formaldehyde Xerogels by Means of Silylation

open access: yesGels, 2022
In materials research, the control of wettability is important for many applications. Since they are typically based on phenolics, organic aerogels, and xerogels are intrinsically hydrophilic in nature, and examples of the chemical functionalization of ...

Impact of pearl-necklace-like skeleton on pore sizes and mechanical properties of porous materials: A theoretical view

open access: yesAIP Advances, 2022
The structural and mechanical properties of open-porous cellular materials are often described in terms of simple beam-based models. A common assumption in these models is that the pore walls have a constant cross section, which may be in agreement for a

Computational design of biopolymer aerogels and predictive modelling of their nanostructure and mechanical behaviour

open access: yesScientific Reports, 2021
To address the challenge of reconstructing or designing the three-dimensional microstructure of nanoporous materials, we develop a computational approach by combining the random closed packing of polydisperse spheres together with the Laguerre–Voronoi ...
