Quantifying Electron and Ion Transfers in Contact Electrification with Ionomers
The concurrent existence of both electron and ion transfers in solid‐ionomer contact electrification is reported. The ion transfer contributes significantly to the process of contact electrification, especially at high humidity, although only less than 2% of ions participate in the ion transfer, suggesting that there is room for further performance ...

Rapid Diagnostics of Reconfigurable Intelligent Surfaces Using Space‐Time‐Coding Modulation
A fast reconfigurable‐intelligent‐surface (RIS) diagnostics method is proposed based on spatio‐temporal modulation with orthogonal codes. Theoretical analysis demonstrates a clear distinction in code channel power between normal and faulty elements. Simulations validate its feasibility under high fault ratios and varying receiving angles.

Ferroelectricity in Single‐Crystalline BaTiO3 Nanodisks on Silicon
Ferroelectricity is studied in 20 nm thick single crystalline BaTiO3 nanodisks when scaling their diameter from ≈ 400 down to 100 nm. For 100 nm diameter, the vertical polarization component adopts three distinct patterns, and the lateral one shows a rotational invariance in‐plane, suggesting a combination of center‐type and flux‐closure domains.
