Nitrogen Reduction Reaction
In article number 2306840, Jun Fan and co‐workers showed that tensile strain tuning the oxidation states of Ti and favoring O‐vacancy formation in Ti2CO2 enhances electrochemical dinitrogen reduction. The downshift of d‐band center leads to unique adsorption behaviors of N‐containing intermediates, which is elucidated by a spin‐polarized d‐band center model.
Electrocatalytic reduction of dinitrogen to ammonia has attracted significant research interest. Herein, it reports the boosting performance of electrocatalytic nitrogen reduction on Ti2CO2 MXene with an oxygen vacancy through biaxial tensile strain engineering. Specifically, tensile strain modified electronic structures and formation energy of oxygen vacancy are evaluated. The exposed Ti atoms with...
Introduction
Pulsed dye laser (PDL) is the main treatment for port wine stain (PWS), but a considerable number of patients show low clearances. The reason for the poor efficacy is related to PDL‐induced angiogenesis. Vascular endothelial growth factor (VEGF) plays an important role in PDL‐induced angiogenesis and can activate the tyrosine kinase activity of VEGF receptor (VEGFR) in endothelial cells...
Poly(vinyl butyral) (PVB) is selected as a promising ethanol‐permselective membrane based on the solubility parameter theory; however, it exhibits anomalous water perm‐selectivity in practical pervaporation (PV) process. Comprehensive analysis based on experimental and theoretical methods were carried out to explore the inherent mechanism of the anomalous performance. Firstly, sum frequency generation...
