Quantum dots enabling all-in-one controllable polymerization through triplet energy transfer

Nature Communications
Colloidal quantum dots (QDs) have recently emerged as a class of initiators or activators for photopolymerization, typically relying on photoinduced charge transfer from QDs to co-additives. Here we report efficient photopolymerization of acrylates using

Immuno-colocalization of EGF-QDs with early endosomes and lysosomes. (

, 2012
A) Intracellular location of EGF-QDs and early endosomes (EEA1) at t = 15, 30, and 45 min. The images show the merging of QD (red) and EEA1 (green) photographs in the same focal plane. Yellow puncta in the merged images indicate colocalization.

QDs do not increase cell-cell fusion.

, 2012
A) HEK-293T cells expressing tdTomato were labelled with QDs and co-cultured with KSC-GFP cells. Flow cytometric analysis showed that QDs did not increase cell-cell fusion over a 3 day time course.

Metal‐Organic Framework‐Templated Construction of Internal Electric Field and S‐Vacancy Defect‐Engineered S‐Scheme Heterojunction for Enhanced Photocatalytic Hydrogen Evolution

EcoEnergy, EarlyView.
A Bi2S3@ZnIn2S4 heterojunction with abundant sulfur vacancies was fabricated through MOF‐templated in situ synthesis. DFT calculations and experiments confirm the presence of an internal electric field (IEF) and S‐scheme charge transfer. The optimized catalyst shows a superior H2 evolution rate of 5.13 mmol·h−1 g−1 under visible light, which is 11.7 ...
