Most existing methods for additive manufacturing (AM) of metals are inherently limited to ~20–50 μm resolution, which makes them untenable generating complex 3D-printed metallic structures with smaller features. We developed a lithography-based process create 3D nano-architected ~100 nm resolution. first synthesize hybrid organic–inorganic materials that contain Ni clusters produce metal-rich photoresist, then use two-photon lithography sculpt polymer scaffolds, and pyrolyze volatilize the...
Scalable synthesis of ultralight, multifunctional, and high-temperature resilient ceramic nanofiber sponges by blow-spinning.
Significance A long-standing challenge in modern materials manufacturing and design has been to create porous that are simultaneously lightweight, strong, stiff, flaw-tolerant. Here, we fabricated pyrolytic carbon nanolattices with designable topologies by a two-step procedure: direct laser writing pyrolysis at high temperature. The smallest characteristic size of the approached resolution limits available 3D lithography technologies. Due unit-cell geometries, reduced feature sizes, quality...
Mechanical metamaterials with three-dimensional micro- and nanoarchitectures exhibit unique mechanical properties, such as high specific modulus, strength, energy absorption. However, a conflict exists between strength recoverability in nearly all the reported recently, particular architected micro/nanolattices, which restricts applications of these materials storage/absorption actuation. Here, we demonstrated fabrication composite nanolattices that overcome strength–recoverability...
Recent developments in mechanical metamaterials exemplify a new paradigm shift called mechanomaterials, which forces and designed geometries are proactively deployed to program material properties at multiple scales. Here, we shell-based micro-/nanolattices with I-WP (Schoen’s I-graph–wrapped package) Neovius minimal surface topologies. Following the topologies, polymeric microlattices were fabricated via projection microstereolithography or two-photon lithography, pyrolytic carbon...
Nanoscale small-volume metallic materials typically exhibit high strengths but often suffer from a lack of tensile ductility due to undesirable premature failure. Here, we report unusual room-temperature uniform elongation up ~110% at flow stress 0.6-1.0 GPa in single-crystalline <110>-oriented CoCrFeNi high-entropy alloy nanopillars with well-defined geometries. By combining high-resolution microscopy and large-scale atomistic simulations, reveal that this ultrahigh is attributed spatial...
Abstract Lead‐free single crystal perovskite materials exhibit impressive characteristics, such as high carrier mobility, low trap density, and long diffusion length. Herein, the high‐performance blue light photodetectors are reported based on lead‐free all‐inorganic Cs 3 Sb 2 Br 9 crystals. These millimeter‐sized crystals have small thermal activation energy of 56.8 meV estimated by temperature‐dependent photoluminescence study. There is no obvious structural phase transition as‐obtained...
The ability to overcome the adverse effect induced by obstacles within transmission link is a central challenge in long-distance optical image and significantly crucial free-space communication. In this work, we introduce an efficient protocol realize robust far-field image-signal modulating spatial-coherence structure of partially coherent random light source. information encoded can be stably transmitted far field resist influence obstructions communication link. This due...
Micro-objects stick tenaciously to each other-a well-known show-stopper in microtechnology and handling micro-objects. Inspired by the trigger plant, we explore a mechanical metastructure for overcoming adhesion involving snap-action mechanism. We analyze nonlinear response of curved beam architectures clamped tunable spring, incorporating mono- bistable states. As result, reversible miniaturized snap-through devices are successfully realized micron-scale direct printing, successful...
Lattice metamaterials have demonstrated remarkable mechanical properties at low densities. As these architected materials advance toward real-world applications, their tolerance for damage and defects becomes a limiting factor. However, thorough understanding of the fracture resistance mechanisms in lattice metamaterials, particularly emerging shell-based lattices, has remained elusive. Here, using combination situ experiments finite element simulations, we show that with Schwarz P minimal...
As is well known, a light beam with helical phase carries an optical orbital angular momentum (OAM), which can cause the motion of trapped microparticles around axis. Usually, speed uniform along azimuthal direction and depends on amount OAM intensity. Here, we present reverse customized method to tailor nonuniform local density focal field, has hybrid polarization distribution maintains doughnut-shaped intensity profile. Theoretical analysis experimental results about polystyrene sphere...

Stretchable and transparent inorganic semiconductors play a key role for the next generation of wearable optoelectronics. Achieving stretchability in intrinsically rigid materials is far more challenging than polymers metals. Here, we present low-cost scalable strategy to engineer into buckling open-mesh configuration, by which extraordinary (≈160%) as well high optical transparency (>86% at 550 nm) can be realized simultaneously SnO2 nanofiber webs. Moreover, mechanical nanowebs further...
Abstract Enhanced dry adhesion of micropatterned polymeric surfaces has been frequently demonstrated. Among the design parameters, cap geometry plays an important role to improve their performance. In this study, we combined experiments on single polyurethane mushroom-shaped fibrils (with a stalk diameter 80 µm and height 125 µm) against flat glass, with numerical simulations implementing cohesive zone. We found that mushroom strongly affects interfacial crack behavior pull-off stress. The...
