Advanced Materials Technologies, Volume 10, Issue 9, May 6, 2025.A stretchable and bendable resistance sensor made predominantly from sustainable and biodegradable components is conductive courtesy a water soluble self‐doped conjugated polymer. The wearable sensor measures micromovements by changes in its resistance and it can track both human movement and phonation. Abstract Sustainable electronic devices offer the

Cavity-enhanced noncollinear high-harmonic generation
, 2019 Femtosecond enhancement cavities have enabled multi-10-MHz-repetition-rate coherent extreme ultraviolet (XUV) sources with photon energies exceeding 100 eV – albeit with rather severe limitations of the net conversion efficiency and of the duration of ...

Phased-Locked Two-Color Single Soliton Microcombs in Dispersion-Engineered Si3N4 Resonators
, 2018 We propose and theoretically investigate a dispersion-engineered Si3N4 microring resonator, based on a cross-section containing a partially-etched trench, that supports phase-locked, two-color soliton microcomb states.
