Advanced Science, EarlyView.BF‐PVA porous film is prepared by doping BF into PVA to form hydrogel and then freeze‐drying and compression to improve the tensile resistance, bending resistance, swelling resistance, degradation time and electrical properties of PVA. Finally, the degradable triboelectric sensor made of BF‐PVA porous film and Mg film is used to realize the signal ...

Effect of minor reactive metal additions on fracture toughness of iron: 12-percent nickel alloy at-196 deg and 25 deg C [PDF]
The slow bend precracked Charpy fracture toughness and tensile behavior of arc-melted and hot-rolled Fe-12Ni alloys containing up to 4 atomic percent reactive metal additions were determined at -196 C and 25 C after water quenching from three annealing ...

Lightweight 3D Hierarchical Metamaterial Microlattices
Advanced Science, EarlyView.In this work, hierarchical lightweight 3D auxetic metamaterials based on cubic crystal lattice truss geometries are proposed. Microscale prototypes are fabricated using two‐photon lithography additive manufacturing and tested in situ. These hierarchical metamaterials are shown to exhibit a wide range of negative Poisson's ratios including giant ...

Thermo‐responsive topological metamorphosis in covalent‐and‐supramolecular polymer architectures
Aggregate, Volume 3, Issue 6, December 2022., 2022 We report a thermo‐responsive topological metamorphosis in covalent‐and‐supramolecular polymer (CSP) architectures wherein supramolecular graft polymer (SGP) transforms into supramolecular polymer network (SPN) based on collaborative dynamic covalent bond chemistry and host−guest chemistry.

Advanced Science, EarlyView.Advanced neoteleost fishbones, such as medaka, challenge bone adaptation strategies. While zebrafish bones contain osteocyte‐mediated porosity, medaka bones lack it, raising questions about alternative reinforcement mechanisms. Using advanced imaging, this study reveals higher residual compressive strains in medaka bone, suggesting an adaptation that ...

Advanced Science, EarlyView.Humanized corneal stroma‐like adhesive patches (HCSPs) are developed for lamellar keratoplasty and corneal perforation repair. HCSPs exhibit histological, optical, and biomechanical characteristics similar to those of the natural cornea, with improved wet tissue adhesion, anti‐degradation, and anti‐swelling capabilities compared to conventional tissue ...
