Ultrathin MXene/EMF composite foams achieve a specific shielding efficiency of 749.6 dB.dB·cm3$\mathrm{dB}\cdot {\mathrm{cm}}^{3}$/g, while the silver‐enhanced MXene/Ag/EMF reaches 81.4 dB shielding effectiveness at just 1.0 mm thickness. Both composites exhibit rapid Joule heating, retain stability up to 250∘C$^\circ{\rm C}$, and withstand 1000 ...

Blending silk fibroin with polycaprolactone alters crystalline organization and surface morphology. Low fibroin levels promote ring‐banded spherulites, while higher contents generate porous, pit‐like textures, though overall crystallinity remains unchanged. Solvent evaporation further modulates surface patterns.

A 4‐layer Kevlar‐based composite is fabricated by combining ultrasonic spraying and electrostatic flocking. Carbon black dispersion is first deposited onto Kevlar fabric to create a conductive electrode. Nylon fibers are then electrostatically flocked onto the coated fabric, forming a dielectric layer.

AbstractFor a hydrogel coating on a substrate to be stable, covalent bonds polymerize monomer units into polymer chains, crosslink the polymer chains into a polymer network, and interlink the polymer network to the substrate. The three processes—polymerization, crosslinking, and interlinking—usually concur.

AbstractThe apparent biocompatibility of many synthetic and natural aqueous gel materials has encouraged their study and testing for a wide variety of biomedical device applications. Many of the physical and in particular the interfacial properties of such gels are highly dependent on the organization of water within and on the surface of the hydrogel.

Gradient hydrogels represent a pivotal and expanding direction of three-dimensional cell culture. Since various types of gradients play an important role in physiological and pathological processes in vivo, recreation of these gradients in vitro allows a better understanding of cellular behavior, intercellular and cell-matrix interactions.
