Direct Gravity‐Induced Modulation of Cardiac Conduction Pathways Evidenced Through Propagation Features in Electrophysiological Mapping

Advanced Materials Technologies, EarlyView.
A high‐density wearable body‐surface potential mapping array reveals how gravity reshapes cardiac conduction in real time. By resolving spatiotemporal delay patterns invisible to conventional ECG, the platform uncovers posture‐dependent electrophysiological adaptations across the thorax.

Aerosol Jet Printed Polymer‐Free High Aspect Ratio Quantum Dot Films for Enhanced Color Conversion

Advanced Optical Materials, EarlyView.
Polymer‐free quantum dot color conversion layers are aerosol jet printed at high aspect ratio by tuning the aerosol focus ratio to induce in‐flight droplet drying. Contact‐line pinning suppresses lateral spreading, enabling ∼10 µm‐thick films at ∼50 µm widths with blue light leakage below 0.25% and conversion efficiency approaching 18%, demonstrated ...

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

Advanced Optical Materials, EarlyView.
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
