Next Generation of Thermal Barrier Coatings with High Temperature Metal‐Silicide Metamaterials

Advanced Optical Materials, EarlyView.
Thermal metamaterials have emerged as a powerful platform in the engineering of radiative heat transfer across a broad range of applications, including thermal imaging, passive cooling, and thermo‐photovoltaics. Here, a novel application is presented for metamaterials: thermal dual barrier coatings (TDBCs).

Gaussian Process Modeling Coronal X-Ray Variability of Active Galactic Nuclei

The Astrophysical Journal
The corona is an integral component of active galactic nuclei (AGNs) that can produce the X-ray emission. However, many of its physical properties and the mechanisms powering this emission remain a mystery.

Chiral Metasurfaces with Multidimensional Tunability for Optical Chiral States

Advanced Optical Materials, EarlyView.
A novel bilayer perovskite chiral metasurface enables tunable transitions between BIC‐associated vortex centres and circularly polarized states via rotational symmetry control. Breaking rotational symmetry and applying in situ rotation to the upper layer allows precise, omnidirectional tuning of C points in momentum space. This evolution forms a Möbius‐

Exploring the Impact of the Presence of 9,9′‐Spirobifluorene Moieties on the Performance of Carbonyl‐Based Multiresonant Thermally Activated Delayed Fluorescence Organic Light‐Emitting Diodes

Advanced Optical Materials, EarlyView.
The impact of decorating the multiresonant thermally activated delayed fluorescence (MR‐TADF) emitter DiKTa with 9,9′‐spirobifluorene units is explored with regard to number, position, and incorporation type. Four novel sky‐blue narrowband MR‐TADF emitters are developed, and in the OLED devices, a structure‐property relationship is observed with ...

Phase Topology Stability of an Optical Vortex via an Electrically Controlled Twist‐Planar Oriented Liquid Crystal Fresnel Lens

Advanced Optical Materials, EarlyView.
A simple and efficient method for determining the stability of optical vortices via Fourier transform using a conventional spherical lens is presented. The theoretical and experimental results demonstrate a practical approach to directly and unambiguously measure the magnitude and sign of the topological charge of a beam without altering an ...

Comparison of the Performance of Fluorescent, Phosphorescent, and TADF Luminophores for Explosives Sensing

Advanced Sensor Research, EarlyView.
Both singlet and triplet populations of the TADF compound 4CzIPN are quenched upon interaction with dinitrotoluene by photoinduced electron transfer. However, their quenching rate is different, with the triplet excitons being more efficiently quenched due to a combination of their longer lifetime and larger population.
