Physiological pH Transition‐Driven Protein Corona Dynamics Regulate Cellular Uptake and Inflammatory Responses of Silica Nanoparticles

open access: yesAdvanced Science, EarlyView.
Physiological pH transitions modulate protein corona dynamics on nanoparticles, altering their cellular uptake and inflammatory responses. Acidic pHs enhance protein adsorption, induce structural changes, and promote cellular uptake. Simultaneously, inflammatory responses are reduced due to altered protein composition, including decreased ...

A Failed Encounter in Mathematics and Chemistry: The Folded Models of van ‘t Hoff and Sachse [PDF]

open access: yes, 2016
Three-dimensional material models of molecules were used throughout the 19th century, either functioning as a mere representation or opening new epistemic horizons. In this paper, two case studies are examined: the 1875 models of van ‘t Hoff and the 1890

Dual Regulation of Molecular Rigidity and Orbital Engineering of Pt(II) Emitters for High‐Performance Deep‐Blue OLEDs

open access: yesAdvanced Science, EarlyView.
Four novel tetradentate Pt(II) emitters (PtCY, PtCY‐F, PtCY‐tBu, PtCY‐tBuF) are designed through synergistic strategy of molecular orbital engineering and steric hindrance effect. PtCY‐tBuF‐based device B4 achieves a high maximum luminance of 45 621 cd m−2, and record high external quantum efficiency (EQE) of 27.1%, 24.3%, and 21.7% at high brightness ...

Enhanced Single‐Particle Upconversion Imaging via Energy Migration Boosting

open access: yesAdvanced Science, EarlyView.
A core‐shell‐shell Yb3⁺/Er3⁺ UCNP architecture is engineered to balance energy migration and back energy transfer, yielding more than a tenfold enhancement in single‐particle brightness. Leveraging these optimized probes, it achieves long‐term, high‐resolution single‐particle tracking in live neurons, uncovering coordinated transport mechanisms of ...
