A multi‐generational compositional design creates a printable low‐loss dielectric composite that achieves over 16 W m−1 K−1. This breakthrough is enabled by thermal post‐processing, which promotes templated crystallization in a polymer matrix from surface‐modified particles, creating a “hetero‐percolated network.” The resulting material is three ...

Superior Adhesion of Monolayer Amorphous Carbon to Copper
The adhesion energy of monolayer amorphous carbon on copper substrate is 85 J m−2, 13 times higher than that of graphene due to covalent‐like bonding between the sp2 carbon structure to copper. X‐ray photoelectron spectroscopy (XPS), near‐edge X‐ray absorption (NEXAFS), and (density functional theory) DFT calculations are used to elucidate the ...

A Multifunctional Binder for Current‐Collector‐Free Zn Powder Anodes
By introducing abundant polar groups as Zn2+ absorption sites and hydrogen bond arrays, a protein structure‐derived binder for ZP anode and iodine cathode is proposed. This design can regulate the Zn2+ flux, benefit the formation of free‐standing electrode, inhibit the side reactions, suppress the shuttle effect of polyiodides, and enable the large ...

The highest experimentally determined focusing efficiency is reported here by using the direct imprinting of all‐inorganic TiO2 metalens arrays. Absolute efficiency greater than 80% and relative efficiency greater than 90% are achieved by optimization of all fabrication parameters controllable in the additive manufacturing process.

Lithium plating mechanisms on 2D‐coated current collectors: PtTe2 coating enables rapid Li surface diffusivity, while PdTe2 and NiTe2 coatings shorten diffusion paths for Li adatoms. In addition, Li2Te, formed from PdTe2 and NiTe2 decomposition, reduces the critical nucleus size by lowering the interfacial energy between the electrolyte and deposited ...

Precision Synthesis of a Single Chain Polymorph of a 2D Solid within Single‐Walled Carbon Nanotubes
The precise synthesis of 1D materials has enabled the discovery of physical properties only accessible in length scales close to the atomic scale. Herein, it is demonstrated that encapsulation within single‐walled carbon nanotubes with matching diameters leads to a stoichiometric quasi‐1D van der Waals polymorph of a 2D pnictogen chalcogenide, Sb2Te3 ...

Synthetic Chromatophores for Color and Pattern Morphing Skins
Cephalopods use chromatophore organs (muscle‐actuated pigment sacs) to alter their skin color and pattern. Synthetic chromatophores, which closely mimic the mechano‐optical process found in cephalopods using stimuli‐responsive microscale hydrogel actuators, are reported.
