Internal triaxial strain imaging of visibly opaque black rubbers with terahertz polarization spectroscopy

open access: yesAPL Photonics, 2017
We demonstrate the nondestructive imaging of internal triaxial strain in visibly opaque black rubbers by employing the polarization-sensitive terahertz time-domain spectroscopy (PS THz-TDS) technique.

Multiscale Coupling From Mastication to Retronasal Aroma Perception: The PG‐DTCFN Model and Multiphysics Simulation

open access: yesAdvanced Science, EarlyView.
Using grilled lamb skewers as a model system, this work builds a multiscale coupling framework from oral processing to retronasal aroma perception, reveals dual‐kinetic release patterns and Electroencephalogram‐characterized central encoding features, and proposes an interpretable physics‐guided deep learning model validated by multiphysics simulation,

From Flow to Function: Using Different Static Mixers to Fabricate Microarchitected Materials Via Chaotic Printing

open access: yesAdvanced Science, EarlyView.
Complex microarchitectures emerge from simple flow‐driven transformations as static mixers iteratively reorient and split material domains. Coupled with diverse deposition strategies, chaotic printing provides an accessible platform for fabricating architected materials that support biologically and chemically relevant processes. ABSTRACT Nature builds

Reference-Free Terahertz Time-Domain Spectroscopy for Direct Measurement of Birefringence and Linear Dichroism

open access: yesPhotonics
Terahertz time-domain spectroscopy (THz-TDS) is a widely used technique for characterizing a broad range of materials in the terahertz frequency region. Conventional THz-TDS requires both reference and sample signals to extract optical parameters such as

Induction and Stabilization of Peptide Alpha‐Helices on Silica Nanoparticles

open access: yesAngewandte Chemie, EarlyView.
Covalent docking turns silica nanoparticles (SNPs) into α‐helix‐stabilizing surfaces. Dynamic imine formation allows peptides with lysine residues aligned on one helical face to adapt to the surface before reduction locks the structure in place, while preserving the opposite face for functional recognition.
