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 ...

Wavy‐Interlocked Stretchable Triboelectric Nanogenerators Enhanced by Liquid Metal Microflowers for Self‐Powered Wearable Motion Monitoring

Advanced Science, EarlyView.
Schematic showing a stretchable triboelectric nanogenerator based on interlocked wavy architectures that uses EGaIn microflower‐embedded PVDF‐TrFE and Nylon‐6 nanofiber membranes. The multi‐petaled, electron‐rich EGaIn microflowers enhance interfacial polarization and capacitance, while the interlocked wavy architecture enlarges the effective contact ...

Axial-Flow Pump with Enhanced Cavitation Erosion Resistance

Energies, 2023
Axial-flow pumps, in addition to providing high anti-cavitation properties, must have high anti-erosion properties to ensure the required lifetime of the pump. Erosion damage of surfaces occurs when the net positive suction head (NPSH) significantly exceeds its critical value.

Cavitation erosion resistance of basalt

, 2020
The cavitation erosion resistance of the basalt samples from Vrelo, Kopaonik deposit was investigated. The cavitation erosion test was performed using an ultrasonic vibratory cavitation testing method in accordance to the ASTM G32 standard. To measure the cavitation resistance, a change in the sample mass in function of the cavitation time was ...
