PICKERING EMULSION TECHNOLOGY IN FABRICATE CELLULOSE FOAM FROM OILPALM EMPTY FRUIT BUNCH WASTE. Cellulose from the oil palm empty fruit bunch (OPEFB) waste can make a porous material. This study aims to cellulose foam with Pickering emulsion technology used nanofiber as agent. The mechanism of is learned foamability and stability in presence various concentrations surfactant. result showed that...

Cellulose nanofibers (CNF) have been applied in various applications due to the abundant raw materials and excellent mechanical thermal properties. In this work, CNF from Cigarette butts (CNF-CB) was used as emulsion stabilized for oil water emulsion. prepared regenerated cellulose fibers that were produced by deacetylation of waste using autoclave then hydrolysis chemical treatment sulfuric ac...

Statistical copolymers of methacrylic acid (MAA) and methyl methacrylate (MMA), butyl (BMA), or lauryl (LMA) were synthesized via cobalt(II)-mediated catalytic chain transfer polymerization (CCTP) used as macromonomeric stabilizers in the emulsion MMA. By varying composition, length, concentration macromonomers, we able to tune particle size, molar mass, rheological behavior latexes. Most latex...

In the preparation of oleogels based on Pickering-emulsions, choice route is critical to withstand drying under ambient conditions, as it conditions composition interfacial layer at oil-water interface. Hexadecane and olive oil were prepared using an emulsion-template approach from oil-in-water emulsions formulated with cellulose nanocrystals (CNC) sodium caseinate (CAS) added in different orde...

Recent experiments have shown that coalescence of an oil/water/nanoparticle Pickering emulsion contained in a vial induces a nanoparticle-film o climb up the walls of the vial. Here we show that this phenomenon is highly general and can be induced by a variety of particle types, particle izes ranging from a few nm to a few m, and different emulsion types. Many of the features of film growth des...

BACKGROUND Emulsions stabilized by colloidal particles are known as Pickering emulsions. To date, soft microgel particles as well as inorganic and organic particles have been utilized as Pickering emulsifiers. Although cyclodextrin (CD) works as an attractive emulsion stabilizer through the formation of a CD-oil complex at the oil-water interface, a high concentration of CD is normally required...

Physical trapping of a hydrophobic liquid oil in a matrix of water-soluble biopolymers was achieved using a facile two-step process by first formulating a surfactant-free oil-in-water emulsion stabilized by biopolymers (a protein and a polysaccharide) followed by complete removal of the water phase (by either high- or low-temperature drying of the emulsion) resulting in structured solid systems...

Formation and stability of emulsions is one of the important topics in the field of colloids and interfacial science. Surfactants and colloidal particles are often used to stabilize emulsions. Surfactants are amphiphilic molecules; they minimize the energy required for the emulsion formation by reducing oil-water interfacial tension. Colloidal particles are not amphiphilic, but partially wettab...

The aim of this research was to introduce a novel method use zein protein and stabilize an ethanol-based emulsion. To study the effect ethanol in continuous phase emulsion on stability microstructure emulsions, content tuned range 50–90%v/v. Also, concentration emulsions examined. mean droplet size were measured using static light scattering (SLS), with Coherent Anti-Stokes Raman Scattering (CA...

In this study, nanoparticle stabilized foam experiments were performed in bulk tests, micromodels, and sandpacks at elevated temperatures and pressures to investigate the flow behavior and displacement mechanisms for enhanced heavy oil recovery. The results from the bulk tests showed that the stability of the foam and oil in water (O/W) emulsion improved when silica nanoparticles (SiO2) were ad...
