Local Quadrupole Ellipticity as Predictor of Anion‐Affinity in Nanographenes

open access: yesJournal of Computational Chemistry, Volume 47, Issue 13, 15 May 2026.
Anion affinity in nanographenes arises from anion–π interactions in electron‐deficient regions and CH‐‐‐anion hydrogen bonds in electron‐rich domains. Quadrupole moments help describe these interactions but have limitations in polycyclic systems. A regression model based on local quadrupole ellipticity predicts binding energies, highlighting local ...

A Tri‐Culture Heart‐on‐a‐Chip Platform With iPSC‐Derived Cardiac Cells for Predictive Cardiotoxicity Testing

open access: yesAdvanced Healthcare Materials, Volume 15, Issue 18, 15 May 2026.
This study presents the first entirely isogenic heart‐on‐chip, unifying cardiomyocytes, fibroblasts, and endothelial cells from a single iPSC source. The platform reveals a critical biological insight: the endothelium actively shields cardiac tissue from drug‐induced toxicity, challenging the predictive accuracy of conventional, avascular models for ...
