Pholidota‐Inspired Electronic Skin Possessing Terahertz‐Wave Reflection–Absorption–Transmission Switchability

Advanced Science, EarlyView.
The pholidota‐inspired electronic skin is successfully constructed, originally realized four‐state reversible switching of terahertz‐wave reflection, absorption, transmission, and secondary reflection. In response to external demands, it issues deformation instructions, verifies the deformation state after the equipment executes the action, and thus ...

Comparative Study on Cavitation Characteristics and Mechanisms of the NACA0015 Hydrofoil under Rotating and Stationary Conditions [PDF]

Journal of Applied Fluid Mechanics
Cavitation characteristics in rotating hydrofoils are crucial for rotating machinery performance. The flow dynamics, significantly influenced by system rotation, differ fundamentally from stationary hydrofoils and require in-depth investigation.

Ultrasound‐Actuated Gene Editing in Human Kidney Organoids

Advanced Science, EarlyView.
Peptide‐stabilized nanoemulsions enable spatially controlled, ultrasound‐triggered delivery of gene‐editing proteins deep within human kidney organoid tissues. Focused acoustic pulses drive droplet vaporization, propelling cargo into target renal cells while preserving native tissue microarchitecture. This non‐viral platform improves both the depth and
