A three-year evaluation of pesticide residue profiles in managed and wild honeybees across traditional and reclaimed agricultural lands of Egypt

Scientific Reports
Pesticide contamination in honeybees directly endangers vital pollinators and serves as a bio-indicator of regional agricultural practices. This is especially important in North Africa (Egypt), which has a unique balance between traditional methods and ...

3D Bioprinted Glioblastoma Multiforme Models: How the Extracellular Matrix Glycosignature Influences Drug Response

Advanced Functional Materials, EarlyView.
Aberrant glycosylation in the glioblastoma tumor microenvironment drives therapeutic resistance. Here, a 3D bioprinted model was engineered by incorporating α‐NeuNAc‐(2→3)‐β‐D‐Gal‐ and chondroitin sulfate. Combined multiplex immunofluorescence and synchrotron‐based nanoCT analysis revealed that glycan‐matrix interactions dictate specific drug‐escape ...

Tetracyclic π‐Extended Multi‐Resonant TADF Emitters for Green PSF‐OLEDs With 37.7% EQE and BT.2020‐Compatible Top‐Emitting Devices

Advanced Functional Materials, EarlyView.
Ultra‐narrow green multi‐resonance thermally activated delayed fluorescence emitters have been developed by linear π‐extension strategy using tetracyclic naphtho[2,3‐b]benzofuran unit. The resulting phosphorescence‐sensitized OLEDs achieve a maximum external quantum efficiency of 37.7% in the bottom‐emitting architecture, while the complementary top ...

Donor‐Engineered Chiral Indium–Salen Complexes for Tunable Circularly Polarized Luminescence

Advanced Functional Materials, EarlyView.
Chiral indium–salen complexes bearing electronically and structurally diverse donor substituents are presented as modular main‐group luminophores exhibiting tunable blue‐to‐green circularly polarized luminescence. Donor engineering systematically controls frontier‐orbital distribution, intraligand charge transfer, and excited‐state relaxation ...

Electrical Tuning of Ferrimagnetic Spin Alignment Angle and Compensation Temperature in Pt/IrMn3/CoGd Multilayers

Advanced Functional Materials, EarlyView.
Spin‐orbit torque controls the Néel vector of antiferromagnetic IrMn3, which selectively exchange‐couples with spins of Co only in the ferrimagnetic CoGd. This selective interfacial pinning induces the non‐collinear spiral spin configuration, leading to a non‐uniform distribution of local compensation temperature along the film thickness, and enabling ...
