Determining Exciton Diffusion Length in Organic Semiconductors: Unifying Macro‐ and Microscopic Perspectives

open access: yesAdvanced Energy Materials, EarlyView.
Exciton diffusion length in organic semiconductor films is determined from encounter/annihilation rates. Non‐normalized exciton densities and proper intrinsic lifetime reference avoid over‐parametrization of the fits. Monte Carlo Simulation of individual molecule‐to‐molecule hops reproduce these results (②) when matching lattice constant and hoping ...

Effect of Propagating Dopant Reactivity on Lattice Oxygen Loss in LLZO Solid Electrolyte Contacted with Lithium Metal

open access: yesAdvanced Energy Materials, EarlyView.
The decomposition of Nb‐substituted LLZO solid electrolytes is reported through a propagating reaction between Nb5+ dopants and the Li metal electrode. This work suggests dopants that segregate to interfaces/grain boundaries in LLZO will exhibit reactivity that can propagate into bulk and shed light on new mechanisms for the problematic role of oxygen ...

Food waste, date labels, and risk preferences: An experimental exploration

open access: yesApplied Economic Perspectives and Policy, EarlyView.
Abstract This study provides theoretical and experimental evidence that consumers adjust their premeditated food waste by date labels and their risk and loss preferences. The “Use by” date label leads to more premeditated food waste than “Best by” for deli meat and spaghetti sauce.
