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.

A Review of Grain Boundaries: Formation Mechanism, Synthesis Strategy, and Application in Electrocatalysis

EcoEnergy, EarlyView.
An overview of grain boundary engineering in the field of electrocatalysis. ABSTRACT Key electrocatalytic reactions such as HER, OER, ORR, CO2RR, and NRR offer promising routes for storing renewable energy as chemical fuels. However, their widespread application is constrained due to the lack of highly active and stable catalysts. Grain boundaries (GBs)

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 ...
