Abstract Phase change materials have attracted significant attention due to their promising applications in many fields like solar energy and chip cooling. However, they suffer leakage during the phase transition process relatively low thermal conductivity. Here, through introducing hard magnetic particles, we synthesize a kind of magnetically tightened form-stable materials. They achieve multifunctions such as leakage-proof, dynamic assembly, morphological reconfiguration, presenting...
Ultra-broad-band electromagnetic absorption materials and structures are increasingly attractive for their critical role in competing with the advanced broad-band detection systems. Mechanically soft weak wax-based composites known to be insufficient serve practical applications. To break through such barriers, here we developed an innovative strategy enable robust repairable meta-structures by employing a three-dimensional (3D) printed polymeric patterned shell. Because of integrated merits...
Abstract Origami structures offer valuable applications in many fields, ranging from metamaterials to robotics. The multistable characteristics of origami have been pursued for acquiring unique reconfigurable features. For achieving this goal, an unusual polymeric tristable structure is demonstrated using a classic square‐twist configuration. By manipulating both material properties and geometric parameters the heteropolymer structures, design principle tailoring configuration established...
Ferroelectric field-effect transistors (FeFETs) based on HfO<sub>2</sub> are promising for low-power and high-speed non-volatile memory devices. However, most reported FeFETs show limited write endurance significant read-after-write delay due to parasitic charge trapping. Here we that n-type with SiN<sub><i>x</i></sub> interfacial layer high also exhibit immediate behavior negligible This overcomes one of the major challenges faced by FeFET technologies today.
Highly homogeneous Al- and Zn-doped TiO2 nanotubes were fabricated by atomic layer deposition (ALD) via nanolaminated stacks of binary layers TiO2/Al2O3 TiO2/ZnO, respectively. The bilayers alternately deposited on the polycarbonate (PC) membrane template ALD with various cyclic sequences. in a length 20 μm diameter 220 nm obtained after removal PC annealing at 450 °C. effects doping composition photocatalytic photoelectrochemical (PEC) activities investigated. Increasing Al reduced activity...
While achieving the spatial organization of cells within 3D assembled nanofiber/cell constructs via nanofiber-enabled cell layering, small sizes inter-fiber pores electrospun nanofiber mats could significantly limit penetration across layers for rapid formation an integrated tissue construct. To address this challenge, efforts were made to improve cell-infiltration by modulating density distribution and fibers during electrospinning. Collection collagen-containing nanofibers (300-600 nm in...
For achieving active shape transformable materials and structures, smart with memory effects along deliberate structure design are generally used as the critical parameters in realizing transformation.

Oriented fibers in bone lamellae are recognized for their contribution to the anisotropic mechanical performance of cortical bone. While increasing evidence highlights that such oriented also exhibit osteogenic induction preosteoblasts, little is known about effect overlay angle between on differentiation marrow-derived mesenchymal stem cells (BMSCs).

Abstract The Masquelet technique that combines a foreign body reaction (FBR)‐induced vascularized tissue membrane with staged bone grafting for reconstruction of segmental defect has gained wide attention in Orthopedic surgery. success hinges on its ability to promote formation “periosteum‐like” FBR‐induced at the site. Inspired by Masquelet's technique, here novel approach is devised create periosteum mimetics from decellularized extracellular matrix (dECM), engineered vivo through FBR,...
