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.

A transformative route to nanoporous manganese oxides of controlled oxidation states with identical textural properties [PDF]

, 2014
Nanoporous nanocrystalline metal oxides with tunable oxidation states are crucial for controlling their catalytic, electronic, and optical properties. However, previous approaches to modulate oxidation states in nanoporous metal oxides commonly lead to ...

Catastrophic disassembly of actin filaments via Mical-mediated oxidation. [PDF]

, 2017
Actin filament assembly and disassembly are vital for cell functions. MICAL Redox enzymes are important post-translational effectors of actin that stereo-specifically oxidize actin's M44 and M47 residues to induce cellular F-actin disassembly.

Accessing the + IV Oxidation State in Molecular Complexes of Praseodymium.

Journal of the American Chemical Society, 2020
Out of the 14 lanthanide (Ln) ions, molecular com-plexes of Ln(IV) were known only for cerium and more recently terbium. Here we demonstrate that the +(IV) oxidation state is also accessible for the large praseodymium (Pr) cation.

Impact of Physico-Chemical Properties of Cellulose Nanocrystal/Silver Nanoparticle Hybrid Suspensions on Their Biocidal and Toxicological Effects

Nanomaterials, 2021
There is a demand for nanoparticles that are environmentally acceptable, but simultaneously efficient and low cost. We prepared silver nanoparticles (AgNPs) grafted on a native bio-based substrate (cellulose nanocrystals, CNCs) with high biocidal ...
