Triggering Anionic Redox Activity in Li₃NbS₄Through Cationic Disordering or Substitution

Theory of tunable pH-sensitive vesicles of anionic and cationic lipids or anionic and neutral lipids.

The design of vesicles that become unstable at an easily tuned value of pH is of great interest for targeted drug delivery. We present a microscopic theory for two forms of such vesicles. A model of lipids introduced by us previously is applied to a system of ionizable anionic lipid and permanently charged cationic lipid. We calculate the pH at which the lamellar phase becomes unstable with res...

Anionic/cationic complexes in hair care.

The formulation of cosmetic products is always more complicated than studying the individual components in aqueous solution. This is because there are numerous interactions between the components, which make the formulation truly more than the sum of the parts. This article will look at interactions between anionic and cationic surfactants and offer insights into how to use these interactions a...

Interactions between Cationic Starch and Anionic Surfactants

Theory of tunable pH sensitive vesicles consisting of anionic and cationic lipids or anionic and neutral lipids

The design of vesicles which become unstable at an easily tuned value of pH is of great interest for targeted drug delivery. We present a microscopic theory for two forms of such vesicles. A model of lipids introduced by us previously is applied to a system of ionizable, anionic lipid, and permanently charged, cationic lipid. We calculate the pH at which the lamellar phase becomes unstable with...

A comparative study of two-stage flotation of Zn and Pb oxide minerals using anionic, cationic, and mixed (cationic/anionic) collectors

A lead-zinc carbonate ore sample containing 2.5% Pb and 9.39% Zn was used in this research work. The sample was prepared from the Darreh-Zanjir mine located in the Yazd province (Iran). Influences of the influential factors on flotation of smithsonite and cerussite were investigated. Among the different parameters involved, dosages of the dispersant, depressants, sulfidizing agent, and collecto...
