Emulsion formation and stabilization by biomolecules: the leading role of cellulose [PDF]
, 2019 Emulsion stabilization by native cellulose has been mainly hampered because of its insolubility in water. Chemical modification is normally needed to obtain water-soluble cellulose derivatives.

Pickering Interfacial Catalysis—Knoevenagel Condensation in Magnesium Oxide-Stabilized Pickering Emulsion [PDF]
ACS Omega, 2020 In the present study, a novel catalytic route for the Knoevenagel condensation reaction has been developed by Pickering interfacial catalysis using magnesium oxide (MgO) as both an emulsion stabilizer and a base catalyst. MgO was prepared by the precipitation method using sodium hydroxide or ammonium hydroxide as the precipitating agent and calcined at

Heterogeneous Pd catalysts as emulsifiers in Pickering emulsions for integrated multistep synthesis in flow chemistry [PDF]
, 2018 Within the “Compartmentalised Smart Factory” approach of the ONE-FLOW project the implementation of different catalysts in “compartments” provided by Pickering emulsions and their application in continuous flow is targeted.

Reconfigurable Pickering Emulsions with Functionalized Carbon Nanotubes
Langmuir, 2021 Pickering emulsions (PEs) achieve interfacial stabilization by colloidal particle surfactants and are commonly used in food, cosmetics, and pharmaceuticals. Carbon nanotubes (CNTs) have recently been used as stabilizing materials to create dynamic single emulsions. In this study, we used the formation of Meisenheimer complexes on functionalized CNTs to

Highly Active, Entirely Biobased Antimicrobial Pickering Emulsions
ChemMedChem, 2021 AbstractWe present the development of surfactant‐free, silica‐free and fully biobased oil‐in‐water antimicrobial Pickering emulsions, based on the self‐assembly of β‐cyclodextrin and phytoantimicrobial oils (terpinen‐4‐ol or carvacrol). Undecylenic acid (UA), derived from castor oil, can be used as bio‐based drug to treat fungal infection, but is less ...
