An Innervated Human Skin Equivalent that Electrically Encodes Mechanical and Thermal Stimuli

Advanced Science, EarlyView.
An innervated human skin equivalent is integrated with high‐density microelectrode arrays to reveal how engineered free nerve ending–like structures translate touch and temperature into electrical codes. Mechanical indentation and thermal stimulation engage the engineered somatosensory circuitry and evoke distinct firing and waveform signatures ...

Origin of Enhanced Efficiency and Reduced Roll‐Off in Organic Light‐Emitting Diodes Based on Pt(II) Complexes

Advanced Science, EarlyView.
Controlled Pt–Pt fine structure in square‐planar Pt(II) complexes governs metal–metal‐to‐ligand charge‐transfer (MMLCT) state formation, exciton dynamics, and organic light‐emitting diode performance. Short Pt–Pt contacts in Pt(fppz)2 enable coherent metal–metal coupling, sub‐microsecond emission and an external quantum efficiency of 29%, whereas ...

Nonlinear Frequency Conversion of Dissipative Soliton Resonance Pulses Using the Second Harmonic Generation Effect

IEEE Photonics Journal
We present the first demonstration of using the second harmonic generation effect to upconvert dissipative soliton resonance laser pulses. We have designed and built two independent dissipative soliton resonance lasers, emitting rectangular shaped ...

Experimental study on harmonic mode-locking in soliton fiber lasers by bidirectional adjustment of pump power [PDF]

Nanotechnology and Precision Engineering
Harmonic mode-locking (HML) in soliton fiber lasers is crucial for generating high-repetition-rate pulse trains beyond the fundamental cavity frequency, enabling advanced applications in, for example, optical communication and precision sensing. However,

From Sensing Mechanisms to System Co‐Design: Graphene‐Based Sensors and Readout Circuits

Advanced Science, EarlyView.
This review establishes a unified PS–EQ–RF framework linking graphene sensing mechanisms, native electrical outputs, and output‐specific readout circuits. Voltage‐, current‐, resistance‐, and capacitance‐type sensing systems are systematically classified to guide architecture selection, low‐noise design, system co‐design, and practical integration ...

GHz harmonic mode-locking in a fiber laser via synergistic action of residual NPR and FBS opto-acoustic phase-locking

We report on the experimental realization of GHz harmonic mode-locking (HML) in an erbium-doped fiber ring laser incorporating a 25-m highly nonlinear fiber (HNLF), enabled by the synergistic action of residual nonlinear polarization rotation (NPR) and ...

Pulse-Amplitude Equalized Rational Harmonic Mode-Locking by Negative Impulse Modulation

, 2006
We have proposed a novel modulation scheme for rational harmonic mode-locking which does not suffer from pulse-amplitude fluctuations, and generated a 15 GHz pulse train with 16 dB harmonic suppression using 1 GHz modulation.

Disorder Driven Anisotropic Nonlinear Hall Effect in the Kagome Metal YbCo6Ge6 at Room Temperature

Advanced Science, EarlyView.
The intrinsic structural disorder and short‐range correlated motifs in the kagome metal YbCo6Ge6 constitute the primary mechanism for a robust and anisotropic nonlinear Hall effect (NLHE). This effect is sustained across a wide temperature range, achieving a nonlinear responsivity of up to ∼4.5 × 10−3 m/V at 70 K, higher than known disordered and ...
