High-entropy alloys are solid solutions of multiple principal elements that capable reaching composition and property regimes inaccessible for dilute materials. Discovering those with valuable properties, however, too often relies on serendipity, because thermodynamic alloy design rules alone fail in high-dimensional spaces. We propose an active learning strategy to accelerate the high-entropy Invar a practically infinite compositional space based very sparse data. Our approach works as...
Novel poly( N ‐isopropylacrylamide)‐clay (PNIPAM‐clay) nanocomposite (NC) hydrogels with both excellent responsive bending and elastic properties are developed as temperature‐controlled manipulators. The PNIPAM‐clay NC structure provides the hydrogel mechanical property, thermoresponsive property of is achieved by designing an asymmetrical distribution nanoclays across thickness. simply fabricated a two‐step photo polymerization. resulted from unequal forces generated thermoinduced...
Artificially-structured materials with negative Poisson's ratio, also known as auxetics, have been the focus of numerous studies over past few decades. In this paper, using a group-theory-based symmetry reduction approach, and based on structure composed rotating rigid triangles, we propose new approach to designing auxetic metamaterials. These metamaterials can be fabricated by variety active or smart structural members that undergo different deformations when subjected external...
In engineering design, origami structures are frequently characterized by their geometry-shifting behavior, mechanical properties, lightness, and appealing aesthetic qualities. particular, conical have attracted increasing attention in recent years owing to excellent energy absorption performance. However, designing with customizable geometry folding morphology has remained a less explored research area. this paper, an artificial intelligence (AI)-based framework is proposed for the design...
In recent years, energy-dissipation devices have gained significant attention in seismic protection engineering because of their effectiveness mitigating the destructive effects earthquakes. Inspired by an origami pattern invented Ron Resch, this study, we propose a novel type brace to guide deformation process and prevent global buckling structures. To end, parametric geometric model is developed, followed exploring different parameters on structural collapse modes. Subsequently, using...
Extending the method coined virtual-center-based (VCB) for synthesizing a group of deployable platonic mechanisms with radially reciprocating motion by implanting dual-plane-symmetric 8-bar linkages into polyhedron bases, this paper proposes first time more general single-plane-symmetric linkage and applies it together to synthesis family one-degree freedom (DOF) highly overconstrained polyhedral (DPMs) motion. The two are compared, geometry kinematics investigated providing geometric...
Abstract In this study, soft hydrogel walkers with electro-driven motility for cargo transport have been developed via a facile mould-assisted strategy. The consisting of polyanionic poly(2-acrylamido-2-methylpropanesulfonic acid- co -acrylamide) exhibit an arc looper-like shape two “legs” walking. can reversibly bend and stretch repeated “on/off” electro-triggers in electrolyte solution. Based on such bending/stretching behaviors, the move their to achieve one-directional walking motion...
A novel and facile assembly strategy has been successfully developed to construct smart nanocomposite (NC) hydrogels with inhomogeneous structures using nanoclay-cross-linked stimuli-responsive hydrogel subunits as building blocks via rearranged hydrogen bonding between polymers clay nanosheets.
