Nanophotonic Design of Germanium‐Silicon Single‐Photon Detectors for Integrated Quantum Photonic Circuits

Nanophotonics, Volume 15, Issue 13, 13 July 2026.
Nanophotonic Ge/Si single‐photon avalanche detectors (SPADs) employing photonic‐crystal‐enhanced optical confinement and a separate absorption–multiplication (SAM) architecture enable near‐unity internal quantum efficiency, low dark current, sub‐50 ps temporal response, and efficient telecom‐band single‐photon detection.

Ultra‐Wideline 2D Correlations Among Low‐γ Species in Solid‐State NMR via the Progressive Saturation of a Common Proton Reservoir

Chemistry – A European Journal, Volume 32, Issue 25, 2 July 2026.
This study introduces PROSPECT, a 2D solid‐state NMR method that correlates MHz‐wide, low‐γ anisotropic powder patterns. PROSPECT operates by progressively depleting a shared 1H dipolar‐order reservoir via two independently stepped cross‐polarizing offsets, yielding homonuclear and heteronuclear correlations without requiring direct transfers or even ...

Mitigating Efficiency Roll‐Off in Phosphor‐Sensitized Fluorescence OLEDs via Molecular Polarity‐Based Benzofuropyridine Host Engineering

Advanced Optical Materials, Volume 14, Issue 25, 3 July 2026.
Positional isomerism in dibenzofuran‐based n‐type hosts modulates molecular polarity, charge‐transport balance, and emissive‐layer packing. The higher‐polarity BFPDB‐2 host facilitates efficient energy funneling, reduced aggregation, and preferential dipole orientation, leading to phosphor‐sensitized fluorescence OLEDs with enhanced external quantum ...

Naphthyridine‐Based Donor–Acceptor Boron Difluoride Complexes Targeting Red Emission in Organic Light‐Emitting Diodes

Advanced Optical Materials, Volume 14, Issue 25, 3 July 2026.
Four donor–acceptor boron difluoride complexes based on triphenylamine donor and a naphthyridine acceptor units were synthesized, studied, and applied as OLED emitters. They exhibit pronounced intramolecular charge transfer character, balanced charge transport properties, and tunable emission. Near‐unity PLQYs are achieved for selected compounds, while

EEG Functional Connectivity Associated With Antidepressant Response to Transcutaneous Electrical Cranial‐Auricular Acupoint Stimulation

CNS Neuroscience &Therapeutics, Volume 32, Issue 7, July 2026.
(A) Fifty MDD patients underwent an 8‐week TECAS treatment and were then classified into responders and nonresponders according to their clinical outcomes. (B) Resting‐state EEG was acquired from all participants and subsequently preprocessed. (C) Functional connectivity analysis revealed that TECAS modulates frontoparietal θ‐band connectivity in MDD ...
