Wood Reconfiguration Enables Broadband Blackbody in Large‐Area, Modular, Optically Welded Carbon Constructs

open access: yesAdvanced Functional Materials, EarlyView.
Wood‐based broadband blackbody is achieved by reconfiguration of wood with lignin nanoparticles prior carbonization. Neglectable reflectivity from the visible to infrared wavelengths is obtained by combining thin nanostructures originated from the wood cell walls with long‐range microcavities in the wood lumina.

Scalable Perovskite Quantum Dot Glass Nanocomposites for High‐Efficiency Luminescent Solar Concentrators

open access: yesAdvanced Functional Materials, EarlyView.
This study evaluates the scalability of PQD GNC‐based LSCs for BIPV applications. Experimental data and Monte Carlo simulations predict performance up to 1 m2, achieving a peak power conversion efficiency of 3.17%. The results confirm the viability of these LSCs for energy‐efficient building applications.

Demonstration of an All‐Optical AND Gate Mediated by Photochromic Molecules

open access: yesAdvanced Functional Materials, EarlyView.
A logic AND gate that runs on photons is demonstrated. It relies on two spatially separated photochromic molecules that work in tandem. Abstract The realization of a photonic logic AND gate, i.e. a logic AND gate that runs on photons rather than electrons, and where all steps are controlled by light, is demonstrated. In a proof‐of‐principle experiment,

Selective Benzene Capture by Metal‐Organic Frameworks

open access: yesAdvanced Functional Materials, EarlyView.
Metal‐organic frameworks (MOFs) hold significant potential for capturing benzene from air emissions and hydrocarbon mixtures in liquid phases. This capability stems from their precisely engineered structures, versatile chemistries, and diverse binding interactions.
