To overcome the main challenge of low performance waterborne polymer coatings due to particulate nature dispersions and complex film formation process, in this work we implemented strategy ionic complexation between oppositely charged particles. For that aim, doubled monomers ithaconic acid (IA) styrenic 1,4-diazabicyclo[2.2.2]octane (DABCO) were used densely functionalize (meth)acrylic forming...

Biopolymer-based films were developed using a mixture of pullulan and agar, the fabricated film was functionalized with bioactive functional components, Pickering emulsion eucalyptus essential oil (PEU), rutin. The color PEU rutin supplemented light yellow. As result, yellowness index increased while whiteness reduced. filler showed biocompatibility pullulan/agar polymer matrix. presence materi...

OPERA (Oscillation Project with Emulsion tRacking Apparatus) is an international collaboration between Europe and Asia, aiming to give the first direct proof of tau neutrino appearance in a pure muon neutrino beam, in order to validate the hypothesis for atmospheric neutrino oscillations. The first european long baseline neutrino beam called CNGS is produced at CERN and sent in the direction of...

Effect of additives on the pore structure of polymer foams obtained from Pickering HIPE templates Various routes were investigated to create pore throats in closed-celled poly-Pickering-HIPEs; we tried to dissolve the silica particles used as emulsifiers out of the thin films separating individual pores by adding NaOH into the aqueous phase, which resulted indeed in the formation of interconnec...

Background: Water in oil (W/O) nanoemulsions can be advantageous for encapsulation of bioactive hydrophilic substance alone or as a structural unit of a double emulsion. Methods: The influence of sonication time, addition of CaCl2 or bovine serum albumin (BSA) to aqueous phase, oil phase (corn or miglyol), and polyglycerol polyricinoleate (PGPR) content on droplet size and physical stability of...

The rational formulation of Pickering double emulsions is described using a judicious combination of hydrophilic and hydrophobic block copolymer worms as highly anisotropic emulsifiers. More specifically, RAFT dispersion polymerization was utilized to prepare poly(lauryl methacrylate)-poly(benzyl methacrylate) worms at 20% w/w solids in n-dodecane and poly(glycerol monomethacrylate)-poly(2-hydr...

Thin emulsion films stabilized with â-casein were studied by microinterferometry. The data demonstrate that the film thickness and intersurface adhesion are influenced by the electrolyte concentration, the prehistory of the protein solution, pH and the presence of fatty acids in the oil phase. A major shift of the film parameters occurs in the presence of calcium ions. The decrease of the film ...

The molecular weight of a polymer determines key optoelectronic device characteristics, such as internal morphology and charge transport. Therefore, it is important to ensure that polymer deposition techniques do not significantly alter the native polymer molecular weight. This work addresses polymers deposited by resonant infrared matrix-assisted pulsed laser evaporation (RIR-MAPLE). By using ...

A numerical model has been developed to investigate the thermally triggered release kinetics for drug delivery using phase change material as shell of microcapsules. Biocompatible material n-Eicosane is used as demonstration. PCM shell of microcapsule will remain in solid form after the drug is taken, so the drug will be encapsulated by the shell, and will not be released until the target body ...

Microfluidic encapsulation platforms have great potential not only in pharmaceutical applications but also in the consumer products industry. Droplet-based microfluidics is increasingly used for the production of monodisperse polymer microcapsules for biomedical applications. In this work, a microfluidic technique is developed for the fabrication of monodisperse double emulsion droplets, where ...
