In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Redox-Responsive Pickering Emulsions Stabilized by Silica Nanoparticles and Ferrocene Surfactants at a Very Low Concentration, published in 2019-10-07, which mentions a compound: 2834-05-1, mainly applied to green pickering emulsion silica nanoparticle ferrocene surfactant stabilized, Recommanded Product: 2834-05-1.
Here, we describe a redox-responsive Pickering emulsion stabilized by silica nanoparticles and a ferrocene surfactant (FcCOC10N) at a concentration as low as 0.01 mM (≈0.005 cmc). The emulsions are stable and resistant to coalescence for more than one month. The ferrocene group in the structure of FcCOC10N can be reversibly switched between its oxidized and reduced forms by redox reactions, which would alter the amphiphilic properties of the surfactant. Consequently, the emulsion can be switched between ′′on′′ (stable) and ′′off′′ (unstable) states through electrochem. reactions without adding addnl. chems. or changing the particle/surfactant concentration Moreover, the Pickering emulsifier composed of the surfactant and the nanoparticles can be recovered and reused after removal of the original oil. It offers a new platform that provides green and sustainable operation for separation and reuse of the emulsifier in potential applications, such as biphasic catalysis and oil transportation. Redox-responsive Pickering emulsions were prepared using silica nanoparticles and a ferrocene surfactant, in which the emulsifier can be recycled and reused without addnl. chems. or expensive equipment.
In addition to the literature in the link below, there is a lot of literature about this compound(11-Bromoundecanoic acid)Recommanded Product: 2834-05-1, illustrating the importance and wide applicability of this compound(2834-05-1).
