Soft actuators with stimuli-responsive and reversible deformations have shown great promise in soft robotics. However, some challenges remain existing actuators, such as the materials involved derived from nonrenewable resources, complex nonscalable preparation methods, incapability of programmable deformation. Here, a biobased ink based on cuttlefish nanoparticles (CINPs) cellulose nanofibers (CNFs) was developed, allowing for biodegradable patterned by direct writing technology. The hybrid CNF/CINP displays good rheological properties, it to be accurately printed variety flexible substrates. A bilayer actuator developed printing an layer poly(lactic acid) film using extrusion-based 3D technology, which exhibits large bending behavior under stimuli humidity light. Furthermore, folding coiling response been achieved adjusting patterns. This work offers fast, scalable, cost-effective strategy development shape-morphing.

3D metal/alloy nanoarchitectures demonstrate transformative potential for next-generation technologies including metamaterials, nanophotonics, and microrobotics. Current nanomanufacturing methods are often restricted to limited metals simple geometries. Herein, we propose a versatile scalable method fabricating metal-alloy through complexation-driven strategy. By leveraging the complexation of metal ions with carboxyl groups, various incorporated into acrylic acid-based polymer scaffolds. Subsequent thermal decomposition reduction transform these scaffolds metallic nanoarchitectures. As most can engage in complexation, successfully fabricated seven distinct elemental their corresponding alloy variants, substantiating versatility our method.

Transparent ceramics face fabrication challenges in achieving high-resolution 3D architectures with optical isotropy and thermal/mechanical stability. While two-photon lithography (TPL) enables nanoscale printing, existing inorganic TPL materials suffer from opacity, big shrinkage, costly postprocessing. Here, we report a solvent-free, high-loading Mg-cross-linked photoresist for of sub-200 nm MgO transparent high fidelity via two-step sintering. With high-purity cubic lattice, defect-free fully dense structures exhibit wide range thicknesses. Demonstrations include excellent imaging, focusing capabilities, stable mechanical durability under various harsh working conditions, like temperature high-energy laser radiation. This simple relatively low-cost method also showcases fiber-integrated micro-optic device high-intensity systems. synergy precision, wide-thickness transparency, outstanding stability will position as next-generation components to make micro-optical devices damage thresholds.
