Dynamics of the formation of a hydrogel by a pathogenic amyloid peptide: islet amyloid polypeptide [PDF]
, 2016 Many chronic degenerative diseases result from aggregation of misfolded polypeptides to form amyloids. Many amyloidogenic polypeptides are surfactants and their assembly can be catalysed by hydrophobic-hydrophilic interfaces (an air-water interface in ...

International Journal of Pharmaceutics, 2003 Bags made of poly-ethylene and poly-vinylchloride and of the copolymer ethylene-vinylacetate were used as containers of perfusion solutions for total parenteral nutrition. The bags were characterised by tensiometry (free energy and its polar and dispersed components) and atomic force microscopy (AFM) before and after various periods of storage of ...

The Hierarchical Structure of Sheep Wool and Its Impact on Physical Properties
Advanced Functional Materials, Volume 35, Issue 52, December 23, 2025.Sheep wool, a prevalent α‐keratinous fiber, is an essential model for studying protein‐based fibers. Its genetic diversity across breeds enables the establishment of multiscale structure‐property relationships, uncovering previously elusive insights into wool's hierarchical structure.

Natural variations in the biofilm-associated protein BslA from the genus Bacillus [PDF]
, 2017 BslA is a protein secreted by Bacillus subtilis which forms a hydrophobic film that coats the biofilm surface and renders it water-repellent. We have characterised three orthologues of BslA from Bacillus amyloliquefaciens, Bacillus licheniformis and ...
