Proximal Steric Shielding Unlocks High Solid‐State Luminescence in Quinoxaline‐Fused Pyrene Heteroacenes

Chemistry – A European Journal, EarlyView.
Proximal steric tuning of quinoxaline‐fused pyrene heteroacenes enables soluble derivatives that exhibit solid‐state photoluminescence quantum yields (PLQYs) up to 82%, surpassing previous benchmarks. This work reveals key structure–property relationships for next‐generation, processable organic emitters in advanced optoelectronic applications ...

Chiral Dipicolinamide‐Based Push–Pull π‐Conjugated Systems as Nonreciprocal Circularly Polarized Luminescence Emitters

Chemistry – A European Journal, EarlyView.
This work presents the synthesis and characterization of chiral dipicolinamide push–pull fluorophores. While possessing similar photophysical properties in solution, their solvent‐annealed thin films exhibit unexpected, nonreciprocal chiroptical activity in both absorption and emission, including a complete inversion of the chiroptical profile upon ...

Crystallization‐Induced Emission Enhancements of Hybrid Butenolide‐Diphenylethenes

Chemistry – A European Journal, EarlyView.
Hybrid butenolide‐diphenylethene fluorophores show crystallization‐induced emission enhancement (CIEE), with substituents tuning solid‐state quantum yields up to 50%. One derivative, BuCM, displays dual‐state emissions (DSE), making this compact scaffold a promising platform for CIEE/DSE‐active fluorophores.

Synthesis, Structures, and Properties of Cyclopenta‐Fused Anthra[1,2‐a]anthracene Derivatives as New Polycyclic Aromatic Compounds

Chemistry – A European Journal, EarlyView.
Three new polycyclic aromatic compounds consisting of one or two five‐membered rings were synthesized by Scholl reaction or Pd‐catalyzed cyclization from fused anthracene derivatives. X‐ray analysis and DFT calculations revealed that these compounds have slightly twisted or curved structures.

Overview of Regulatory Guidelines Related to Methods and Models for Small Populations

Clinical Pharmacology &Therapeutics, EarlyView.
This paper provides an overview of approaches and related guidelines from the EMA, FDA, and ICH that are relevant for obtaining clinical evidence for small populations to support regulatory decision making. The approaches are grouped into three categories: (1) maximizing the attainable sample size, (2) adapting the trial design to deal with a small ...

First SOLPS‐ITER Simulation Study of Japanese DEMO on Leakage of Seeded Ar Impurity

Contributions to Plasma Physics, EarlyView.
ABSTRACT For JA DEMO, one of the grand challenges is efficiently handling the extreme power loads onto plasma‐facing components, particularly the divertor targets. Impurity seeding is an essential strategy for increasing the radiation losses and thereby reducing the heat load on the targets.

Transition Metal Compounds as Thermochromic Materials: Classification, Properties, Limitations, and Applications

EcoEnergy, EarlyView.
This review systematically examines how different transition metal compounds—such as binary and multinary metal oxides, halides, sulfides, and salts—exhibit thermochromism based on the d‐electron configurations of their transition metal cations. It focuses on three main mechanisms of thermochromism: phase transition, charge transfer, and bandgap change.

Light‐Induced Structural Reorganization of Fe Centers Unlocks High Efficiency of Visible‐Light Photo‐Fenton Water Cleaning Catalyst

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Bimetallic Cu and Fe oxide species supported on porous silica with interparticle mesoporosity act as efficient photo‐Fenton‐like catalysts under visible light. Photogenerated electrons drive the Cu2+/Cu1+ redox cycle. Part of Cu1+ is responsible for the regeneration of the Fe3+/Fe2+ cycle at neutral pH. Light irradiation additionally induces structural
