Single‐Pulse Femtosecond Laser 3D Multi‐Foci Light‐Field Engineering via Multi‐Layer Noise Threshold Filtering

open access: yesAdvanced Science, EarlyView.
This study presents a single‐pulse femtosecond laser strategy for three‐dimensional multi‐foci light‐field shaping and high‐throughput micro/nano manufacturing. The multi‐layer noise threshold filtering algorithm improves focal quality, while the multi‐layer over‐sampling algorithm increases focal density.

Bendable grating for monochromatization of extreme-ultraviolet light

open access: yesOptics Express
Gratings used in laboratory applications such as compensated and non-compensated monochromators have usually a plane geometry and require additional optical elements, mirrors, to focalize the selected spectral component. An active grating, whose curvature radius can be adjusted with a suitable mechanism, can at the same time select a spectral component

Van der Waals Gap‐Confined Molecular Engineering of MoS2 for Selectivity‐Enhanced and Humidity‐Tolerant Gas Sensing

open access: yesAdvanced Science, EarlyView.
Molecular confinement within van der Waals gaps of MoS2 is established as a powerful design strategy for selective and stable chemical sensing. Ethanol‐confined films simultaneously tune electronic doping, surface wettability, and sulfur vacancy configurations, suppressing water interference while enhancing NO2 adsorption.

Mode‐Resolved Phonon Dynamics Under Chemical Pressure in SnTe Thermoelectrics

open access: yesAdvanced Science, EarlyView.
Chemical pressure reshapes low‐energy optical phonons in SnTe, altering their dispersion and scattering with heat‐carrying acoustic modes. Positive and negative pressure states modify phonon frequencies and lifetimes in distinct ways, revealing how mode‐selective lattice perturbations regulate acoustic–optical interactions and suppress lattice thermal ...

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

open access: yesAdvanced 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.
