Advanced Materials Interfaces, EarlyView.Amphiphilic non‐isocyanate polyurethane (NIPU) coatings containing reactive hydrophobic poly(dimethylsiloxane) (PDMS) and hydrophilic methoxy poly(ethylene glycol) (MPEG) prepolymers for marine antifouling (AF) and fouling‐release (FR) applications were investigated. The coatings were evaluated with a set of representative marine foulants.

Advanced Materials Technologies, EarlyView.Dense tactile streams from across the humanoid body converge on collide in a central wiring and data bottleneck. By relocating computation closer to and then into the skin itself, near‐ and in‐sensor architectures, together with neuromorphic computing, chart a path toward perception‐native electronic skin, in which the conversion of stimulus into ...

Zero‐Waste Manufacturing of Ophthalmic Lenses by Direct Fluidic Shaping in Arbitrary Domains
Advanced Materials Technologies, EarlyView.Conventional ophthalmic lens manufacturing discards up to 97% of material through subtractive processes. The Cookie Cutter algorithm extends Fluidic Shaping to arbitrary rim geometries. The framework prescribes a spatially varying boundary height that, under neutral buoyancy and surface tension, shapes curable polymer into spherocylindrical lenses that

Red‐Light Tomographic Volumetric 3D Printing in Seconds for Fabrication of Colorless Structures
Advanced Materials Technologies, EarlyView.A custom red‐light‐responsive TVAM platform combines methylene blue, triethanolamine, and PEGDA to fabricate transparent crosslinked hydrogels. Light patterns are projected into a rotating resin container, where a sacrificial photoinitiator system enables rapid polymerization and colorless channel‐containing structures, utilizing low‐energy light for ...
