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

open access: yesAdvanced Science, EarlyView.
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 ...

A Versatile Three Dimensional Traction Force Microscopy Framework for Uncovering the Mechanics of Bio‐Adhesion

open access: yesAdvanced Science, EarlyView.
This study introduces a versatile platform for quantifying three dimensional traction forces at bio‐adhesive interfaces. Integrating in situ stereo‐digital image correlation with finite element simulations allows for precise measurement of microscale displacements and traction forces in both dry and wet conditions.

Wave‐Partition‐Governed Dual‐Site Spallation in Single Crystals

open access: yesAdvanced Science, EarlyView.
Crystalline anisotropy shapes shock‐wave propagation and the resulting damage evolution in single crystals. Large‐scale molecular dynamics and damage modeling uncover a dual‐spallation mechanism driven by anisotropic elasticplastic wave separation, which mitigates damage accumulation.

A Sustainable Adhesive Paradigm: Reversibly Reinforcing, Heat‐Free Bonding with Universal Substrates

open access: yesAdvanced Science, EarlyView.
A heat‐free adhesive system, delivering superior adhesion strength across metal, plastic, and glass substrates, is developed. Repeatable bonding with reinforcement instead of strength reduction enables error‐tolerant applications. This design paradigm establishes an eco‐friendly alternative to conventional adhesives, particularly suitable for ...
