From simple micelles in water, nearly spherical aggregates of amphiphilic molecules, to bicontinuous microemulsions, oil and water microheterogeneous mixtures stabilised by a surfactant film with both local large-scale disordered structures, the world surfactant-containing systems is fascinating. Depending on subtle balance attractive repulsive interactions between molecules at interfaces, an extraordinarily rich polymorphism aggregated structures can be observed. After summarising basic...
The stabilization of o/w Pickering emulsions in cases weak adsorption solid particles at the surface oil droplets is addressed. Though usually very strong and irreversible when partial wetting conditions are fulfilled, electrostatic repulsions between charged act against adsorption. regime was reached using silica nanoparticles high pH low ionic strength. O/w diisopropyl adipate were stabilized by colloidal Ludox® AS40 consisting non-aggregated bare (hydrophilic). combination stability...

Clay-armored polymer particles were prepared by emulsion polymerization in the presence of Laponite platelets that adsorb at surface latex and act as stabilizers during course polymerization. While RDS clay are most often used, choice type still remains an open issue is addressed present article. Four different grades investigated styrene. First, adsorption isotherms clays, on preformed polystyrene particles, determined ICP-AES analysis residual aqueous phase. Adsorption depended low...
Pickering emulsions provide a new way to enhance the efficiency of photocatalytic degradation water-insoluble pollutants. Indeed, semiconductor solid particles dually act as photocatalyst and stabilizer emulsion droplets whose size dramatically affects reaction. The present work aims at validation this concept by using bare TiO2 without any surface modification. Nanostructured has been prepared simple sol-gel process characterized X-ray diffraction, specific area analysis, scanning electron...
The choice of the functional monomer is a key point in design molecularly imprinted polymers (MIPs) because its directional interactions with template molecules are required to form molecular imprints acting as selective recognition sites for adsorption. Methacrylic acid (MAA) has very often been employed imprinting basic molecules. Strong acid-base lead H+ transfer and weak hydrogen bonding between products reaction. weakly acidic acrylamide (AA) shown stronger hydrogen-bonding histamine...
This paper reports the development of novel adsorbent materials using polyaniline (PANI) grafted onto Posidonia (POS) fibers, aimed at efficiently removing phenol red (PSP), an anionic dye, from aqueous solutions. The synthesis involved copolymerization aniline on surface POS and monomer in solution, resulting a chemically bound thin PANI layer bioadsorbent. Structural characteristics binding affinities these adsorbents with under its emeraldine salt (POS@PANI-ES) or base (POS@PANI-EB) forms...
