Ultrahigh Piezoelectricity in Truss‐Based Ferroelectric Ceramics Metamaterials
By leveraging the unique combination of polarization direction and loading state, ultrahigh piezoelectricity is achieved through careful tuning of the relative density and scaling ratio in truss‐based ferroelectric metamaterials. This approach enables the simultaneous realization of extremely high piezoelectric constants and ultralow dielectric ...

Harnessing Outer Space for Improved Electrocaloric Cooling
A novel radiative heat sink/source‐integrated electrocaloric (R‐iEC) system combines the electrocaloric (EC) effect with a thermally conductive radiative cooler (TCRC) to address heat dissipation limitations in EC devices. Utilizing outer space as a heat sink, the system achieves up to 240 W m−2 of heat dissipation performance, making it highly ...

Streamer characteristics of dielectric natural ester-based liquids under long gap distances
Natural esters, as the renewable resources, offer excellent physiochemical and dielectric properties such as the fire-resistance, high biodegradability and satisfactory dielectric breakdown performance. Thus, natural esters are selected as the insulation

The THz drive of the Mott insulating state of a rare‐earth nickelate induces instantaneous insulator‐metal transition via quantum tunneling of valence electrons across the bandgap. This transition is pure electronic and highly non‐thermal, which may find its applications in ultrafast opto‐electronics with enhanced performance and minimal device size ...

This review highlights recent advances in engineering artificial antigen‐presenting cells (aAPCs) as alternatives to dendritic cells for T cell expansion. Key design principles inspired by the immunological synapse are discussed, with emphasis on strategies for polyclonal and antigen‐specific T cell expansion.
