Triply‐Twinned Metamaterials: Unraveling the Mechanics and Failure Pathways Through High‐Resolution XCT

open access: yesAdvanced Materials, EarlyView.
Triply‐twinned architected lattices transform deformation from bending to stretching of struts, delivering up to threefold increases in stiffness and strength across polymeric and metallic systems. High‐resolution synchrotron XCT and image‐based simulations reveal how meta‐grain architecture, defects, and AM build orientation govern failure pathways ...

A Nano‐Interception Strategy for Chronic Heart Failure: Prussian Blue Nanoparticles Disrupt Fibroblast‐Immune Communication via CCL2 Sequestration

open access: yesAdvanced Materials, EarlyView.
A nano‐interception strategy disrupts pathogenic fibroblast–macrophage crosstalk in chronic heart failure. Scalable Prussian blue nanoparticles selectively sequester CCL2 via ultrahigh‐affinity binding, preventing CCR2+ macrophage recruitment and breaking a key fibro‐inflammatory circuit. This approach demonstrates robust efficacy in murine and porcine

Plasma‐Sequence‐Engineered Atomic Layer Deposition of Ultra‐Thin SiNx for Enhanced Etching Resistance in Extreme Ultraviolet Pellicles

open access: yesAdvanced Materials Interfaces, EarlyView.
Plasma‐sequence‐engineered ALD (PSE‐ALD), based on sequential NH3 and N2 plasma pulses, enables ultrathin, dense SiNx films. ToF‐MS analysis confirms ligand removal via HCl evolution, while increased film density indicates network densification. The resulting SiNx coating provides robust protection of graphite under H2 plasma exposure.

NASA. Langley Research Center dry powder towpreg system [PDF]

open access: yes
Dry powder polymer impregnated carbon fiber tows were produced for preform weaving and composite materials molding applications. In the process, fluidized powder is deposited on spread tow bundles and melted on the fibers by radiant heating to adhere the

Light‐Programmable Interfaces: From Molecular Photoswitching to Adaptive Membrane Separations

open access: yesAdvanced Materials Interfaces, EarlyView.
This review advances an interface‐centered framework for light‐responsive membranes, linking molecular photoswitches (azobenzene (AZO), spiropyran (SP), diarylethene (DAE), donor–acceptor Stenhouse adducts (DASA), photoacid) to integration strategies in polymeric, porous, self‐assembled, and mixed‐matrix systems.

Bonding of Acrylic Pressure‐Sensitive Adhesives and Silicone Elastomers via Surfactant‐Assisted Plasma Activation for Soft Robotics

open access: yesAdvanced Materials Interfaces, EarlyView.
A simple strategy is presented for bonding acrylic PSAs and silicone elastomers by curing surfactant‐doped Ecoflex on oxygen‐plasma‐treated VHB. The interface reaches a maximum strength of 1.6 N/mm (over 20 times that of the control) while retaining material compliance.

Characterizing the variation of propagation constants in multicore fibre [PDF]

open access: yes, 2014
We demonstrate a numerical technique that can evaluate the core-to-core variations in propagation constant in multicore fibre. Using a Markov Chain Monte Carlo process, we replicate the interference patterns of light that has coupled between the cores ...
