Intracrystalline Void‐Mediated Toughening of Brittle Crystals in Quail Eggshells

open access: yesAdvanced Functional Materials, EarlyView.
In quail eggshells, the high density and disordered arrangement of intracrystalline voids inhibit lattice cleavage, suppress long‐range crack propagation, and promote deformation twinning and quasi‐plasticity, serving as an essential toughening motif. We show that these voids remain within a narrow subcritical size range and therefore predominantly do ...

Switching Superconductivity with Uniaxial Strain in a high‐Tc${\rm T}_{c}$ Cuprate Superconductor

open access: yesAdvanced Functional Materials, EarlyView.
Uniaxial strain is demonstrated as a new scheme for a superconductivity switch. Exploiting the large strain‐induced Tc shift in a cuprate superconductor enables robust switching between superconducting and normal states over 100 cycles with only 0.1% strain.

Bistable Isochoric Chiral Metamaterials with Reprogrammable Multiaxial Responses

open access: yesAdvanced Functional Materials, EarlyView.
An isochoric bistable rotational unit cell enables in situ modification of internal contact conditions post‐fabrication, without altering the global envelope dimensions of the surrounding architecture. By selectively switching between open and closed states, the tessellated chiral metamaterial can reprogram its volumetric response, including bulk ...

In Situ Interfacial Assembly of Dynamic Semi‐Interpenetrating Biopolymer Networks for Robust and Mechanically Adaptive Droplet Interfaces

open access: yesAdvanced Functional Materials, EarlyView.
A dynamic interfacial semi‐interpenetrating polymer network is constructed by sequential assembly of β‐sheet‐rich SF and CS‐RL. The SF framework provides mechanical strength, while dynamically associated CS‐RL enables local rearrangement, allowing droplets to rapidly reconfigure without loss of interfacial integrity.

Modulation of Surface‐Associated Transport in (Bi1‐xSbx)2Te3 via Battery‐ Inspired Solid‐State Iontronic Gating

open access: yesAdvanced Functional Materials, EarlyView.
Iontronic gating in a battery‐inspired device modulates the relative weight of surface‐associated and bulk‐like transport fingerprints in (Bi1‐xSbx)2Te3, resulting in phenomenological valve‐like transport behavior. The strongest WAL‐associated coherent transport signatures emerge near the transport‐defined carrier compensation regime at ultra‐low gate ...

Protease‐Activated Theranostic Nanomedicine for Endometriosis Treatment

open access: yesAdvanced Functional Materials, EarlyView.
Endometriosis is a chronic gynecological disorder that affects a substantial proportion of reproductive‐aged women. In this study, we identify aberrant overexpression of matrix metalloproteinase‐9 (MMP‐9) in endometriotic lesions and develop a novel multifunctional nanomedicine that integrates MMP‐9‐targeted therapy, ratiometric photoacoustic (PA ...

The Role of Viscoelasticity in Heterogeneous Glioblastoma Stem Cell Invasion in Biomimetic 3‐Dimensional Hydrogels

open access: yesAdvanced Healthcare Materials, EarlyView.
The role of viscoelasticity in the invasion of heterogeneous glioblastoma stem cells (GSCs) was investigated with GSCs categorized into subgroups based on molecular profile, as Reactive, Invasive, or Constructive using viscoelastic biomimetic hyaluronan‐oxime hydrogels.
