Analytical Prediction of Critical Transitions in Oscillator Networks With Non‐Local Links

Advanced Science, EarlyView.
An analytical framework reveals how global coupling, second‐harmonic strength, noise, and network structure govern oscillator‐based Ising dynamics. Spectral reduction predicts stability boundaries, while Fokker–Planck analysis captures one‐ to two‐cluster transitions and identifies conditions favoring low‐energy configurations.

A Compact and Fast Single‐Spike TTFS Encoder With Ultralow Operating Voltage for Efficient Neuromorphic Fourier Transform

Advanced Science, EarlyView.
A Pt/TaOx/V single‐spike TTFS encoder achieves ultralow‐voltage (∼0.35 V), high‐speed (∼100 ns) operation with simplified circuitry. Integrating bipolar nonuniform temporal encoding with a spiking‐DFT neuron model enables a neuromorphic FFT framework. Device‐calibrated simulations demonstrate high spectral fidelity across multitone, speech, and chirp ...

Chiral‐Nematic Lattice Instability in Charge Density Wave of 1T‐TiSe2

Advanced Science, EarlyView.
The charge density wave of 1T‐TiSe2 appears chiral to surface probes yet loses all symmetry in spectroscopic measurements. This study reveals how cooperative condensation of multiple phonon modes stabilizes a chiral monoclinic ground state, while a shallow nematic energy landscape allows the lattice to break the remaining symmetry at negligible cost ...

Rapid Solidification Brings Ultralow Thermal Conductivity and Superior Thermoelectric Performance for Intrinsic GeTe Alloy

Advanced Science, EarlyView.
Rapid solidification with glass fluxing is first applied to the intrinsic GeTe alloy and achieves large undercooling within 2 h. This enables partial retention of the high‐temperature cubic phase at room temperature and forms a crystallographically oriented α+β dual‐phase structure and a hierarchical defect network.

Product‐Reshaped Gas‐Phase Hydrodynamics Govern CO2 Electrolysis in Gas Diffusion Electrodes

Advanced Science, EarlyView.
In gas‐fed CO2${\rm CO}_2$ electrolysers, the gas phase is part of the electrochemical response. As gaseous products form, they change gas composition and flow, which in turn affects CO2${\rm CO}_2$ delivery and CO intermediate availability. This feedback changes the reaction environment needed for multicarbon formation, becoming unavoidable as ...
