High‐Efficiency TADF Dendritic Emitters Enabled by Synchronously Inhibiting Degenerated Triplet Excited States and Structural Relaxation Toward Solution‐Processed OLEDs with EQE Over 33%

open access: yesAdvanced Science, EarlyView.
Asymmetrical thermally activated delated fluorescence dendritic emitters are delicately constructed through symmetry breaking strategy, and near‐unity photoluminescence efficiency and excellent reverse intersystem crossing process are achieved via breaking the degeneracy of vibrational levels and boosting the spin flip of triplet excitons.

Unveiling Copper‐Induced Phase Transitions and Degradation Mechanisms of Transition Metal Sulfide Anodes for Sodium‐Ion Batteries

open access: yesAdvanced Science, EarlyView.
Sodium polysulfides, which are generated from TMS anodes, react with the Cu current collector, thereby triggering Na‐Cu–S interfacial phase formation. Simultaneously, transition metals undergo ionization and redeposition on the counter electrode. The coupled processes drive the phase evolution of TMS toward the stable Cu1.8S phase.

‘A wedding through a piece of glass’: Transnational Tunisian family communication as driver of ICT adoption

Media, Culture & Society, 2022
This study focuses on the role of ICT in transnational communication between family members, mainly between elderly parents and adult children living abroad. A semi-structured interview study (N = 32) was conducted during Fall 2015 in three neighborhoods
