Adsorption Preceding Wetting Front Controls Seismic Velocity
Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract Rock elasticity varies with both humidity and water saturation, yet their combined effects remain poorly understood, although in nature vapor adsorption and liquid infiltration occur simultaneously. Here, we present experimental data of P‐wave velocity and volume expansion in a free‐standing sandstone subject to progressive wetting.

Advanced Functional Materials, Volume 36, Issue 32, 20 April 2026.Light reflectance increases along incidence angle and transmittance significantly drops around 90‐degree incidence angle. Here, we report two‐photon laser printed micro mirrors that redirect the skimming light beam into normal light absorption. Using this technique, light‐driven micro walkers and grippers are demonstrated by using grazing incidence ...

Quasi‐Single‐Mode Polaritonic Crystal for Hyperbolic Phonon‐Polaritons
Advanced Optical Materials, Volume 14, Issue 13, 3 April 2026.Near‐field study of the polaritonic Fourier crystal with α‐MoO3 reveals that the hyperbolic phonon‐polaritons within the Type‐I Reststrahlen band may form a quasi‐single‐mode Bloch wave where only the fundamental mode propagates in the crystal. Our results demonstrate the realization of a quasi‐single‐mode regime for the inherently multimode hyperbolic

Advanced Science, Volume 13, Issue 23, 23 April 2026.A meta‐YAG crystal with artificially order/disorder structures was fabricated to realize the efficient third‐harmonic generation at 343 nm with a conversion efficiency of 4.5×10−3, surpassing six orders of magnitude compared to bulk YAG crystal. Moreover, a wide spectral tunability from 331 to 356 nm was also achieved in the meta‐YAG, indicating its ...
