Engineering Pt nanoclusters on CeO2 surface with abundant point defects by in situ confined-domain encapsulation strategy for the catalytic elimination of VOCs† [PDF]

RSC Applied Interfaces, 2023
Pt nanoclusters are a promising catalyst for VOC catalytic combustion, but they have been rarely studied so far. Herein, Pt nanoclusters (Pt NCs) and Pt nanoparticles (Pt NPs) were constructed by an in situ confined-domain encapsulation strategy, and ...

Chemodivergent transformations of amides using gem-diborylalkanes as pro-nucleophiles

Nature Communications, 2020
Amides are versatile synthetic building blocks, however the general stability of the amide bond makes its selective transformation challenging. Here, the authors report a chemodivergent transformation of primary, secondary and tertiary amides by using 1 ...

Effect of Water Chemistry on Zeta Potential of Air Bubbles

International Journal of Electrochemical Science, 2013
Effects of various factors on zeta potential of air bubbles in aqueous solution were studied. It was found that the water pH, surfactants types and concentration, and water temperature had significant roles on the zeta potential of air bubbles.
