Superior strength-ductility synergy of an oxide-dispersion strengthened CoCrNi-based multi-principal element alloy [PDF]

CoCrNi-based multi-principal element alloys (MPEAs) often lack strength at elevated temperatures. Here, to overcome this deficiency, a novel oxide-dispersion strengthening (ODS) CoCrNi-based MPEA was designed by incorporating nano-scale yttria via LPBF ...

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 ...
