Abstract: A hydrogel consists of a cross-linked polymer network and water. There are various types of molecule chains in the polymer network, including long chains, short chains, and dangling chains. Under tensile loading, the long ...

Abstract: As 2D materials with subwavelength thicknesses, elastic metasurfaces show remarkable abilities to manipulate elastic waves at will through artificial boundary conditions. However, current elastic metasurfaces are still far ...

Abstract: Introducing inelastic dissipaters can enhance the adhesion of hydrogels. However, the adhesion energy enhanced by inelastic dissipaters dramatically decreases when the adhesion interface is loaded repeatedly. Here, we ...

Abstract: Metallic glasses (MGs) are often perceived as quintessential structural materials due to their superior mechanical properties such as high strength and large elastic limit. In practical applications, service conditions ...

Abstract: Covalent adaptable network (CAN) polymers can rearrange their macromolecular network by bond exchange reactions (BERs), where an active unit attaches to and then replaces a unit in an existing bond and forms a new bond. ...

Abstract: Most tough hydrogels suffer accumulated damages under cyclic loads. The damages may stem from breakage of covalent bonds, unzipping of ionic crosslinks, or desorption of polymer chains from nanoparticle surfaces. Recent ...

Abstract: Aside from ultrahigh strength and elasticity, metallic glasses (MGs) possess a number of favorable properties. However, their lack of dislocation based plastic deformation mechanisms in crystalline metals and the resulting ...
