Phosphor‐Sensitized Ternary Organic Solar Cells Achieving 18.6% PCE via Ir(III)‐Mediated Triplet Energy Transfer and Non‐Radiative Recombination Suppression

open access: yesAdvanced Science, EarlyView.
A synergistic phosphor‐sensitization strategy (PSS) significantly enhances ternary OSCs performance. By integrating an Ir‐3 complex as a triplet energy mediator within a pyrazine‐based (N2) ternary blend (PM6:N2: L8‐BO) doped with 1 wt.% of Ir‐3 complex, and a PCE of 18.6% is achieved through efficient triplet‐triplet energy transfer (TTET), suppressed

Quantification of torsional stiffness in running footwear: proposed methodology

open access: yes, 2017
There is evidence to suggest that certain extrinsic factors, such as footwear, may contribute to risk of running injury. Torsional shoe stiffness quantifies the resistance of a shoe to twisting about its long axis between the heel and toe box, and has ...

A Novel Reactive Oxygen Species‐Responsive Bone‐Targeted Nanoplatform Based on Cloperastine Attenuates Ovariectomy‐Induced Bone Loss by Inhibiting Osteoclast Oxidative Phosphorylation

open access: yesAdvanced Science, EarlyView.
Cloperastine suppresses osteoclastogenesis by inhibiting PGC1β‐mediated oxidative phosphorylation. Its incorporation into a ROS‐responsive, Asp8‐modified nanoplatform enhances skeletal accumulation. The resulting Clo/Asp8‐PMK‐MCs combine cloperastine‐mediated antiresorptive activity with carrier‐mediated osteogenic activity to attenuate OVX‐induced ...

A Programmable Braided Silk‐Glass Fiber Ligament Promoting Rapid Motoric Recovery

open access: yesAdvanced Science, EarlyView.
A scalable three‐dimensional braiding strategy integrates silk and glass fibers into customizable artificial ligaments with programmable “J‐shaped” nonlinear mechanics. The silk‐rich architecture supports osseoligamentous integration, while glass fibers provide mechanical reinforcement and biomimetic mineralization cues, enabling strain‐adaptive load ...

Hydrodynamic Selection of Polymorphic Assembly Pathways in Plant Protein Amyloid Fibrils

open access: yesAdvanced Science, EarlyView.
Hydrodynamic conditions are revealed to govern polymorphic assembly of soy protein amyloid fibrils. Distinct flow‐induced drafting, kissing, and docking dynamics direct fibril growth into multiple morphologies, linking fluid mechanics with nanoscale assembly and enabling rational design of functional amyloid materials.
