Stable, Reusable Copper‐Bispidine Catalysts on Agarose With Diffusion‐Limited Turnover: When Immobilization is not Covalent

European Journal of Inorganic Chemistry, EarlyView.
Epoxy‐activated agarose beads as support for copper(II)‐bispidine complexes provide reusable heterogeneous catalysts for styrene aziridination with negligible copper leaching. Immobilization occurs largely through noncovalent interactions. Catalyst loading strongly governs performance by balancing active‐site density, accessibility, and mass transport.

Limited sex‐specific structural alterations across common epilepsies: A worldwide ENIGMA study

Epilepsia, EarlyView.
Abstract Objective Epilepsy is characterized by widespread cortical and subcortical structural alterations beyond the epileptic zone. Importantly, the clinical manifestation of epilepsy, including seizure types, psychiatric comorbidities, and treatment responses, has been shown to differ between sexes. However, sex differences in structural alterations

Rare genetic variation in adults with surgically treated temporal lobe epilepsy: An exome sequencing study

Epilepsia Open, EarlyView.
Abstract Objective To determine the frequency of monogenic variants and pathogenic copy number variants (CNVs) in adults with surgically treated temporal lobe epilepsy (TLE). Methods We performed exome sequencing (ES), including CNV analysis, in 45 adults with TLE who had previously undergone epilepsy surgery.

Resonant States Reveal Strong Light–Matter Coupling in Nanophotonic Cavities

Laser &Photonics Reviews, EarlyView.
Photonic resonant states reveal characteristics of coupled light–matter systems that would otherwise be hidden by damping. Their trajectories (when tuning the optical resonance) undergo a qualitative change at the onset of strong coupling: They start swapping positions.

From Planar to 3D Nanophotonic Lenses: Advancing Design, Fabrication, and Applications

Laser &Photonics Reviews, EarlyView.
Three‐dimensional nanophotonic lenses are enabled by an integrated workflow that links design parameterization, full‐wave electromagnetic simulation, computational optimization, and freeform fabrication. This Review summarizes how these tools expand optical design freedom beyond a single patterned plane by enriching the local meta‐atom response and ...

Host–Dopant Engineering of Ce4+‐Dominant Y3(Al,Ga)5O12:Ce,Mg Scintillators for High‐Performance X‐Ray Imaging

Laser &Photonics Reviews, EarlyView.
Mg2+ co‐doping strongly suppresses defect‐related emission and luminescence from trace impurities. Moreover, Mg2+ co‐doping improves the scintillation performance of Y3Al3Ga2O12:Ce by increasing the light yield and accelerating the decay time.
