Critical Coupling in Semi‐Trasparent Fano Resonators for Photothermal Converters

open access: yesAdvanced Functional Materials, EarlyView.
An ultrathin metal–insulator multilayer architecture is engineered to exploit Fano‐resonant critical coupling, completely suppressing optical reflectance while achieving a balanced 50:50 trade‐off between absorbance and transmittance. Upon laser excitation at resonance, the metamaterial generates intense localized heat (ΔT≈550∘C$\Delta T {\approx }550^\

Thermal conductivity of zirconia thermal barrier coatings [PDF]

open access: yes, 1995
Thermal barrier coatings (TBC's) applied to the hot gas components of turbine engines lead to enhanced fuel efficiency and component reliability. Understanding the mechanisms which control the thermal transport behavior of the TBC's is of primary ...

Exceptional Electro‐Optic Coefficient Unlocked via Polarization Swaying in KNbO3 Thin Films

open access: yesAdvanced Functional Materials, EarlyView.
We present the largest reported electro‐optic response in any material to date, guided by a new design principle that exploits ultralow coercive field polarization swaying enabled by low‐symmetry ferroelectric phases in monoclinic KNbO3 thin films for energy‐efficient classical and quantum photonic integrated circuits. ABSTRACT The electro‐optic effect

Controlling Structure and Stability in Ultrathin Ti3C2Tx MXene Multilayers for Hydrogen Gas Barrier Applications

open access: yesAdvanced Functional Materials, EarlyView.
An ultrathin nanocomposite MXene‐based multilayer effectively blocks hydrogen permeation by presenting a tortuous, layered structure. When the MXene is layered with reduced graphene oxide modified with a polycation, the resulting nanocomposite retains its hydrogen gas barrier properties at temperatures as high as 400°C (permeability of 7.13 ± 0.09 × 10−

Programming Neuromorphic Plasticity Through Ionic and Electronic Coupling in Organic Electrochemical Transistors

open access: yesAdvanced Functional Materials, EarlyView.
Neuromorphic plasticity in OECTs is governed by the post‐stimulus evolution of coupled ionic and electronic states. Semiconductor chemistry and morphology, electrolyte composition and interfaces, and device architecture regulate ion injection, transport, confinement, and release, shifting responses from rapidly relaxing STP to metastable memory and ...

Spectral emittance measurements for ytterbium disilicate‐based environmental barrier coatings

open access: yesInternational Journal of Ceramic Engineering & Science
The spectral reflectance and transmittance of two free‐standing ytterbium disilicate (Yb2Si2O7)—based environmental barrier coatings (EBCs) were measured from 25°C up to 1270°C.

Molecular Bridges for 2D Nanomaterials

open access: yesAdvanced Functional Materials, EarlyView.
Molecular cross‐linking provides a versatile strategy to engineer interfaces in 2D materials. By tuning the linker backbone, binding mode, and interflake spacing, molecular bridges can regulate charge transport, mechanical integrity, chemical functionality, and processing.

Self‐Adaptive Gradient Interphase Enables Durable Solid‐State Lithium Metal Batteries

open access: yesAdvanced Functional Materials, EarlyView.
This work presents a machine learning‐guided interfacial design that forms a self‐adaptive graded interphase on lithium metal anode. A B105M40 composite interlayer evolves into lithiophilic, porous, and fast‐ion‐conducting phases, enabling intimate contact, dendrite suppression, and uniform lithium deposition.

Flame‐Retardant Expandable Graphite–Polymer Composite Putty for High‐Temperature Triboelectric Nanogenerators and Shape‐Adaptive Cyclic Fire‐Warning

open access: yesAdvanced Functional Materials, EarlyView.
This work introduces shape‐adaptive, flame‐retardant (FR) expandable graphite–filled polymer composite putty that unites moldability, self‐healing, adhesion, conductivity, and exceptional fire‐shielding performance to enable FR–TENGs and cyclic fire warning systems operable on complex and irregular 3D surfaces. ABSTRACT Self‐powered, flexible, and fire‐
