Highly Luminous Scintillating Nanocomposites Enable Ultrafast Time Coincidence Resolution for γ‐rays Detection with Heterostructured Multilayer Scintillators

open access: yesAdvanced Functional Materials, EarlyView.
A scintillating polymeric composites loaded with hafnia nanoparticles is engineered to obtain a highly luminous material, thus achieving a 400% improvement of the scintillation yield under soft X‐rays. The nanocomposite is employed to realize a multilayer heterostructured prototype scintillator than enable for ultrafast time coincidence resolution in ...

Bi‐Directional Assembly of Boron Nitride µ‐Platelets by Micro‐Molding for Advanced Thermal Interface Materials

open access: yesAdvanced Functional Materials, EarlyView.
Bi‐directionally assembled BN µ‐platelets in micropatterns formed by a micro‐molding method for thermal interface materials are demonstrated. The BN µ‐platelets are vertically aligned selectively, while compressed regions without patterns accommodate horizontally assembled BN µ‐platelets. Through anisotropic orientation, high thermal conductivities for

Elucidating Sodium Ion Storage Mechanisms in Hard Carbon Anodes at the Electronic Level

open access: yesAdvanced Functional Materials, EarlyView.
High‐resolution, multi‐frequency continuous wave, and pulsed Electron Paramagnetic Resonance (EPR) spectroscopy uncover the intricate Na ion storage mechanisms in hard carbon. This study reveals the coexistence of Na ion intercalation and solvent co‐intercalation, alongside a subsequent transition of Na ions from ionic to quasi‐metallic to metallic ...

Heat Conduction Modulation in Incommensurate Twisted Stacking of Transition‐Metal Dichalcogenide

open access: yesAdvanced Functional Materials, EarlyView.
The interlayer thermal conductance in twisted bilayer TMDs is initially investigated experimentally by the thermoreflectance method. The overlap of lattice vibrations within individual layers and the interlayer interactions, as elucidated through both Raman spectroscopy and molecular dynamics simulations, are demonstrated to be critical factors in ...
