Effects of Adding Nanosilica on Acrylic and Siloxane Hydrophobic Coatings to Protect Calcite Stones [PDF]

open access: yesعلوم و تکنولوژی پلیمر, 2019
Hypothesis: Both acrylic and siloxane polymers show good water-repellency when applied on the surface of mineral materials, such as bricks and stones. This property makes them an option to protect the porous surfaces of mineral, such as stone artworks ...

Low‐Fraction Irregular Inclusions Trigger Large Compression Stiffening in Biopolymer Hydrogels

open access: yesAdvanced Functional Materials, EarlyView.
Irregular inclusions at low filler fractions trigger large compression stiffening in biopolymer hydrogels. By promoting contact‐network formation under compression, these inclusions induce non‐affine rearrangements, stretch surrounding fibers, and provide parallel load‐bearing pathways.
