  5. Completing singlet and triplet exciton management in fluorescent/phosphorescent hybrid white organic light-emitting devices: stable high-utilization blue emitters, resonant energetic alignment, and predictive modeling of exciton losses

  6. Open problems in room-temperature organic-microcavity polariton condensation: loss-limited ground-state populations, quantitative feeding mechanisms, finite-lifetime thresholds, polariton-versus-photon lasing criteria, and the path to electrical driving

  7. Predictive switching physics and array-level validation of the hybrid PEDOT:PSS-fuse / thin-film-silicon-diode write-once read-many-times (WORM) memory

  8. Realization of a directly electrically pumped (current-injection) organic semiconductor laser diode, with quantified management of injection losses

  9. Microscopic origin of the mobility enhancement at OTS-modified gate dielectrics in pentacene thin-film transistors, and the decoupling of grain size from field-effect mobility
