Anionic Polysaccharide Cryogels: Interaction and In Vitro Behavior of Alginate–Gum Arabic Composites
Polymers, 2023 In the present study, polysaccharide-based cryogels demonstrate their potential to mimic a synthetic extracellular matrix. Alginate-based cryogel composites with different gum arabic ratios were synthesized by an external ionic cross-linking protocol ...

Macroporous Silk Fibroin Cryogels
Biomacromolecules, 2013 Silk fibroin cryogels with remarkable properties were obtained from frozen fibroin solutions (4.2-12.6%) at subzero temperatures between -5 and -22 °C. This was achieved by the addition of ethylene glycol diglycidyl ether (EGDE) into the cryogelation system.

Advances in tailoring the porosity of tannin-based carbon xerogels [PDF]
, 2015 Usually, carbon xerogels are obtained from resorcinol–formaldehyde organic gels. However, more cost-effective and eco-friendly carbon xerogels can be synthesised by using tannins instead of resorcinol, provided that a suitable surfactant is added to ...

Biopolymer Cryogels for Transient Ecology‐Drones
Advanced Intelligent Systems, 2023 Aerial robots can autonomously collect temporal and spatial high‐resolution environmental data. This data can be utilized to develop mathematical ecology models to understand the impact of climate change on the habitat. In case of drone malfunction, the incorporated materials can threaten vulnerable environments.
