Cross‐Phase Modulation via Time‐Varying Epsilon‐Near‐Zero Metasurfaces
Time‐varying epsilon‐near‐zero metasurfaces are shown to enable cross‐phase modulation beyond conventional ENZ excitation. By engineering dual absorption bands and exploiting oblique ultrafast pumping, large and broadband frequency translations are achieved at low pump energies.

Optical and plasmonic properties of TiN and Ti(O)N thin films were tuned at the synthesis stage by modulating the oxygen pressure during room‐temperature pulsed laser deposition. Ti(O)N thin films exhibiting a highly metallic and peculiar double‐epsilon‐near‐zero (DENZ) behavior were produced.

Quasi‐Random Nanostructured Substrates for Enhancing Light Outcoupling in OLEDs
ABSTRACT Organic light–emitting diodes (OLEDs) suffer from low light outcoupling efficiency, with much of the generated light trapped within the device. To address this issue, we present a scalable, maskless, polymer‐free strategy for fabricating quasi‐random external nanowire (ENW) and internal nanocorrugation (INC) structures directly on glass ...

Dry soft Ti3C2Tx MXene electroencephalography (EEG) electrodes provide low impedance (2.1 ± 1.8 kΩ at 10 Hz), long‐term stability, and enable safe simultaneous EEG and transcranial magnetic stimulation (TMS). Across scalp sites, hair types, and recording paradigms, including steady state visual evoked potentials (SSVEP), clinical EEG, and mobile EEG ...
