Unified Analytical Framework for Understanding the Operational Stability of Blue Phosphorescent OLEDs: Quantitative Insights Into Exciton Recycling and Bimolecular Interactions

open access: yesAdvanced Functional Materials, EarlyView.
Blue phosphorescent OLEDs remain limited by poor operational stability. Here, a unified analytical framework integrating transient photoluminescence and magneto‐electroluminescence is developed to correlate intrinsic material photophysics with electrically driven degradation.

A Proposal for a UK Ethics Council for Animal Policy: The Case for Putting Ethics Back into Policy Making

open access: yesAnimals, 2018
Substantial controversy is a consistent feature of UK animal health and welfare policy. BSE,~foot and mouth disease, bovine TB and badger culling, large indoor dairies, and wild animals in circuses are examples.

Wood Cellulosic Membrane With Abundant Nanochannels for Stabilizing Aqueous Zn‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
A wood‐derived cellulosic membrane separator is developed to suppress dendrite growth in aqueous zinc‐ion batteries. Its aligned nanochannels and hydroxyl‐rich surfaces enable uniform Zn2+ flux, water immobilization, and interfacial stabilization. Zn||Zn cells achieve 1920 h of cycling, Zn||Cu cells maintain 99.5% Coulombic efficiency over 1000 cycles,

Microscopic Origin of Temperature‐Dependent Anisotropic Heat Transport in Ultrawide‐Bandgap Rutile GeO2

open access: yesAdvanced Functional Materials, EarlyView.
Rutile GeO2${\rm GeO}_{2}$ exhibits orientation‐dependent heat transport with temperature‐dependent anisotropy, showing higher cross‐plane thermal conductivity along [001] than along the equivalent in‐plane [100] and [010] directions. Temperature‐dependent TDTR measurements and first‐principles phonon calculations identify the microscopic phonon ...

Functional Blood‐Brain Barrier Crossing by Biomimetic M13 Phage Vectors for Targeted Neuronal Delivery

open access: yesAdvanced Healthcare Materials, EarlyView.
This study investigates the M13 bacteriophage as a biomimetic nanovector capable of crossing in vitro models of the blood–brain barrier. By exploiting peculiar transcellular pathways, M13 avoids lysosomal degradation and preserves its structural integrity and functionality.

A Systematic Study of GelMA‐Carbopol Bioinks for High‐Fidelity Extrusion 3D Bioprinting at Physiological Temperatures

open access: yesAdvanced Healthcare Materials, EarlyView.
Gonzalez Martinez and collaborators develop a strategy to formulate high performance GelMA‐based bioinks with low solids contents. The resulting bioinks enable 3D bioprinting at 37 °C of high‐fidelity structures with tunable mechanical properties that support high cell viability and function.

Counterintuitive Fluorescence Blue Shift in Symmetry Breaking Dicationic Bis(indolium) with Two‐Photon Absorption Properties for NIR Living Cell Imaging

open access: yesAdvanced Materials, EarlyView.
Highly water‐soluble dicationic bis(indolium) dyes have been prepared, showing excellent two‐photon absorption and light emission. Their fluorescence behavior discloses an unusual increasing blue shift with increasing solvent polarity, which, in parallel, is beneficial for enhanced detection in biological media.

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

open access: yesAdvanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and
