Deterministic Nucleation of Nanocrystal Superlattices on 2D Perovskites for Light‐Funneling Heterostructures

Advanced Materials, EarlyView.
This work investigates the heterogeneous nucleation of CsPbBr3${\rm CsPbBr}_3$ nanocrystal superlattices along the faces of 2D PEA2PbBr4${\rm PEA}_2{\rm PbBr}_4$ layered perovskite microcrystals. Core–crown and core–shell heterostructure morphologies are obtained.

Hydrophobic MFI‐Type Zeolites via Alkali‐Cation‐Induced Defect Healing: Implications for Adsorbent and Catalyst Design

Advanced Materials, EarlyView.
Sub‐stoichiometric amounts of Na+ or K+ enhance defect healing during Silicalite‐1 (MFI) and TS‐1 calcination by promoting Si–O–Si annealing and healing framework vacancies. The resulting defect‐free zeolites are more hydrophobic and show improved butanol/water separation and improved activity and selectivity in the epoxidation of 1‐hexene, offering a ...

Unveiling the Hidden Geometry of OECTs: Contact‐Semiconductor Overlap Driven Errors in Volumetric Capacitance

Advanced Materials Technologies, EarlyView.
This work examines how contact–semiconductor overlap influences volumetric capacitance extraction in organic electrochemical transistors as device dimensions shrink. It shows that neglecting overlap leads to systematic, geometry‐driven errors in capacitance values.

Stirring‐Induced Modulation of NIR Emission in Tm3+‐Doped Nanoparticles: Evidence of Apparent Risetime Sensitivity

Advanced Optical Materials, EarlyView.
Motion was found to induce significant variation in the luminescence intensity ratio of NIR‐emitting Tm3+‐doped NaYbF4 nanoparticles, which has been ascribed to the population dynamics of the Tm3+ ion's excited states. These findings provide the groundwork for the design of motion nanosensors that can operate in environments not accessible with UV–vis ...

NIR I‐to‐NIR I Time‐Gated Luminescence Detection From Tm3+‐Doped Gd3TaO7 for Deep Tissue Imaging

Advanced Optical Materials, EarlyView.
A new generation of optical imaging (OI) using temporal resolution, exploring a NIR I‐to‐NIR I biological window emission by a Phonon Assisted Conversion (PAC) system singly doped with Tm3+ ions. Although still in early development, this approach opens new directions for designing optimized fluorophores to enhance bioimaging performance.

Tailoring Amine Substitution in Fluorene and Dibenzothiophene: A Molecular Strategy for Ultralong Organic Phosphorescence

Advanced Optical Materials, EarlyView.
Tailored amine substitution in fluorene and dibenzothiophene derivatives enables systematic control of excited‐state properties and triplet population. Combined photophysical studies, TD‐DFT calculations and time‐resolved EPR reveal how charge‐transfer character, sulfur‐induced spin–orbit coupling and triplet manifold engineering cooperate to promote ...
