Advanced Energy Materials, EarlyView.A high‐resolution image‐based multiphase and multi‐physics modelling framework is developed to decouple structural changes in the membrane electrode assemblies of high‐temperature proton exchange membrane fuel cells. These changes are then digitally combined to show how morphological defects such as membrane pores, catalyst cracks, and phase migration ...

Advanced 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 ...

Transport Resistance Dominates the Fill Factor Losses in Record Organic Solar Cells
Advanced Energy Materials, EarlyView.Organic photovoltaics are a promising solar cell technology, but even the record devices with 20% efficiency have significant fill factor losses due to low active layer conductivities. In this Perspective, the authors describe the origin of these losses, discuss experimental methods for their quantification, and explain how to minimize them to optimize

Discerning Performance Bottlenecks of State‐of‐the‐Art Narrow Bandgap Organic Solar Cells
Advanced Energy Materials, EarlyView.This work quantitatively discerns the loss mechanisms of state‐of‐the‐art low‐bandgap organic solar cells based on BTPV‐4X‐eC9 acceptors. Compared to PM6:Y6, geminate recombination of charge transfer (CT) states governs photocurrent losses. This relates to conformational freedom of these acceptors that restricts their aggregation, and also counteracts ...

Advanced Energy and Sustainability Research, EarlyView.Less metal, more distance! The ReOx‐Pd/CeO2 catalyst, an active heterogeneous catalyst for the consecutive deoxydehydration and hydrogenation of vicinal diol, suffers a gradual loss of activity throughout its use due to the polymerization of monomeric ReOx active species.

Advanced Energy and Sustainability Research, EarlyView.An aqueous potassium‐ion battery using vanadium hexacyanoferrate (VHCF) as the cathode and graphite as the anode is presented. During charge/discharge, K+ ions shuttle between electrodes through the electrolyte, enabling energy storage. The VHCF material demonstrates high capacity (≈121 mAh g−1), fast kinetics, and eco‐friendliness, making it a ...

Dynamic site‐interconversion reduces the induction period of methanol‐to‐olefin conversion
AIChE Journal, EarlyView.Abstract Reaction–diffusion coupling across the catalyst pore, grain, pellet, and reactor bed has been studied using a particle‐resolved transient microkinetic model applied to temperature‐programmed desorption and step‐response studies of methanol and dimethyl ether conversion over ZSM‐5 catalysts, respectively.

AIChE Journal, EarlyView.Abstract The modernization of pharmaceutical manufacturing is driving a shift from traditional batch processing to continuous alternatives. Synthesizing end‐to‐end optimal (E2EO) manufacturing routes is crucial for the pharmaceutical industry, especially when considering multiple operating modes—such as batch, continuous, or hybrid (containing both ...
