Micellization of true amphoteric surfactants
Journal of Colloid and Interface Science, 2013The physical chemical behavior of a series of N-alkyl amino acid-based surfactants has been investigated. The series comprises four different types of amino acids as polar headgroups: glycine, aminomalonic acid, aspartic acid and glutamic acid, and for each type three homologues were synthesized: the octyl, decyl and dodecyl derivative.

The formation of the Wheland or Meisenheimer cr-complexes the wellknown phenomena in chemistry of aromatics and heteroaromatics [1, 2] is a key step in the both classical SE2Ar and SN2Ar substitution. The ability of arenes and hetarenes to form predominantly the cationic or the anionic type of s-complexes is, in general, determined by the p-excessive ...

Two Amphoteric Silver Carbene Clusters
Angewandte Chemie, 2018AbstractTwo highly labile silver carbene cluster complexes are described, which are unique in that they mark the transition point at which the carbene center transmutes from a fairly common NHC‐like nucleophilic behavior to an electrophilic character befitting reactive silver carbene intermediates of relevance in various catalytic transformations. This

Amphoteric CdSe nanocrystalline quantum dots
Nanotechnology, 2008The nanocrystal quantum dot (NQD) charge states strongly influence their electrical transport properties in photovoltaic and electroluminescent devices, optical gains in NQD lasers, and the stability of the dots in thin films. We report a unique electrostatic nature of CdSe NQDs, studied by electrophoretic methods.
