Advanced Functional Materials, EarlyView.This study presents a novel donor‐bridge‐acceptor‐bridge‐donor (D‐B‐A‐B‐D) molecular system, which shows near‐unity intramolecular excitation energy transfer (IET) from two identical energy donors to a coplanar acceptor. It enables a four‐level energy system for efficient lasing at the acceptor emission band in a microspherical cavity with a low lasing

Cardiomyopathy Induced by Artificial Heart Stimulation
Journal of Cardiac Arrhythmias, 2020 With the advent of cardiac pacemakers more than 60 years ago, the era of artificial cardiac pacing began, which changed the natural history of symptomatic bradycardias, significantly increasing the survival especially of patients with complete ...

1D Light‐Emitting MAPbBr3 Perovskite Encapsulated in Carbon Nanotubes
Advanced Functional Materials, EarlyView.Encapsulation of MAPbBr3 perovskite in single‐walled carbon nanotubes (SWCNTs) yields a hybrid nanomaterial with distinctive optoelectronic properties. Perovskite confinement induces a unified single‐peak photoluminescence (PL) with a reduced lifetime, while charge transfer alters the optical properties of nanotubes.

A Universal Biomimetic Approach for Making Artificial Antigen‐Presenting Cells for T Cell Activation
Advanced Functional Materials, EarlyView.This study shows a biomimetic silica microcapsule (SMC) fabrication method under mild conditions for making artificial antigen‐presenting cells (aAPCs). Inspired by marine biomineralization, peptide‐mediated biosilicification enables silica shell formation on emulsion templates. The resulting SMCs possess a core–shell structure, controlled fluorescence
