Uniform In‐Plane Growth of Large‐Area Ultrathin Zn2(benzimidazole)4 Membrane

Advanced Functional Materials, Volume 36, Issue 11, 5 February 2026.
A multicycle, ultradilute exposure strategy enables uniform in‐plane growth of ultrathin Zn2(benzimidazole)4 membranes on graphene, suppressing bulk nucleation and defects. The resulting centimeter‐scale films deliver high H2/CO2 separation performance, and are highly reproducible.

Probing Ultrafast Coherent Bandgap Modulation in Monolayer WSe2 by Nonlinear Optics

Advanced Optical Materials, Volume 14, Issue 5, 2 February 2026.
This work sheds light on how resonant nonlinear optics blursthe line between perturbative and non‐perturbative nonlinear optics. Measured deviationsfrom the quadratic second‐harmonic scaling near the excitonic resonance arisefrom optical Stark and Bloch‐Siegert shifts. The experimental results arefurther underpinned by analytical and numerical analysis

Structural Stability‐Driven Dynamic Range Analysis of Carbon Nanotube Photo‐Thermoelectric Sensors

Advanced Sensor Research, Volume 5, Issue 2, February 2026.
This work clarifies that surface adhesiveness of supporting substrates dominantly governs response signal dynamic ranges for pn‐junction type carbon nanotube (CNT) film photo‐thermoelectric sensors. Chemical agents constituting substrate adhesion degrade the pn‐junction of the device, which inherently serves as the most sensitive photo‐detection ...

Formation of Condition‐Dependent Alpha‐Synuclein Fibril Strain in Artificial Cerebrospinal Fluid

Advanced Science, Volume 13, Issue 7, 3 February 2026.
α‐synuclein aggregation in artificial cerebrospinal fluid (aCSF) leads to a distinct conformation with an electron density pocket motif found in aggregates from PD and MSA patients. Such fibrils has low stability outside the reaction conditions, hinting about the influence of cerebrospinal fluid components not only on the formation, but also on the ...

Damage‐Free Full‐Thickness Dicing of Ultra‐Thin GaAs Wafers Using a Femtosecond Laser with Low Residual Stress

Advanced Science, Volume 13, Issue 7, 3 February 2026.
This study presents a femtosecond laser‐based ultrashort pulse dicing system that uses a non‐diffracting Bessel beam to shape the femtosecond laser. The use of femtosecond Bessel beam shaping and high‐speed scanning enables rapid material removal that outpaces thermal diffusion, thereby suppressing melting, minimizing the HAZ, and reducing sidewall ...
