Selective Deposition of Charged Droplets for Programmable and Rewritable Printing of Patterned Microstructure Arrays

Advanced Science, EarlyView.
A residual‐charge‐induced electric field control (SDREC) strategy enables the fabrication of patterned microstructure arrays with a resolution of 20 µm via the selective deposition of charged droplets. The resulting arrays exhibit reversible writing/erasing, optical encryption, and selective silver electrode formation, offering a versatile route to ...

Transient Terahertz Oscillations During Photoinduced Polarization Topology Reconfiguration in Ferroelectric Superlattices

Advanced Science, EarlyView.
Terahertz resonances in crystalline heterostructures could close a spectral gap between conventional electronics and photonics while opening new windows on non‐equilibrium lattice dynamics. Femtosecond optical screening of the depolarization field in epitaxial PbTiO3/SrTiO3 superlattices launches a collective polar mode that oscillates near 1 THz and ...

Absorption‐Dominant Electromagnetic Interference Shielding of Ti3C2Tx MXene‐Coated and Fe3O4‐Integrated TPMS Composites with Coupled Gradient Conductivity and Size‐Graded Structure

Advanced Science, EarlyView.
A functionally driven variable‐cell size and gradient‐conductive coated TPMS structure was developed. Accordingly, stepwise longitudinal gradient impedance was realized, achieving absorption‐dominant EMI shielding (absorptivity≈0.85) with an EMI SET of ≈ 59 dB, for 10 mm‐thick composites. Further increasing the thickness of composites to 20 mm achieved

Optimization Techniques on Permittivity Distribution in Permittivity Graded Solid Insulators

Optimization Techniques on Permittivity Distribution in Permittivity Graded Solid Insulators
We have proposed a new concept for solid insulation; an application of FGM (Functionally Graded Materials). By controlling the distribution of dielectric permittivity inside solid insulators, we can achieve the efficient field control with keeping simple configuration of solid insulators.
