Surface dressings are a sustainable maintenance alternative for pavements with surface distresses, due to the low amount of resources involved. This paper aims analyze viability using twelve different dressing solutions, including three binders (conventional and modified emulsions, soft 160/220 bitumen) covering diluted emulsion, treatment Portland cement concrete (PCC) pavements. Several test ...

Antioxidant potential of the fungal dye, produced by a strain selected from the collection of Epicoccum nigrum bioresearch platform (acronym MIUG) was partially characterized in previous studies. However, the fungal dye antioxidant capacity compared with other potential colorant inhibitors of lipid peroxidation (e.g. cochineal dye) has not been fully elucidated, especially regarding its behavio...

Biodegradable poly(D, L-lactide-co-glycolide) (PLGA) and PLGA-based polymeric nanoparticles are widely used for sustained release of protein and peptide drugs. These formulations are usually prepared by water/oil/water (W/O/W) and solid/oil/water (S/O/W) double emulsion solvent evaporation method. Other methods of preparation are nanoprecipitation, emulsion solvent diffusion and salting-out. Th...

Plasmid DNA was encapsulated within poly(d,l-lactic-co-glycolic acid) (PLGA) nanospheres by using polyethylene glycol (PEG) assisted solubilization technique of plasmid DNA in organic solvents. Plasmid DNA was solubilized in an organic solvent mixture composed of 80% methylene chloride and 20% DMSO by producing PEG/DNA nano-complexes having an average diameter less than 100 nm. DNA could be sol...

Figure 2. (A) bp-s-PFG experiments for both components of the emulsion. Note that the signal decay is isotropic for both. (B) Angular bpd-PFG experiments with tm=0 ms, reveals the presence of μA for both compartments. (C) Angular bp-d-PFG experiments with long tm= reveals that toluene is diffusing within spheres, and the presence of csA for water, demonstrating that the water molecules are trap...

Low color visibility and poor mechanical strength of polystyrene (PS) photonic crystal films have been the main shortcomings for the potential applications in paints or displays. This paper presents a simple method to fabricate PS/MWCNTs (multi-walled carbon nanotubes) composite photonic crystal films with enhanced color visibility and mechanical strength. First, MWCNTs was modified through rad...

A review of the state of knowledge on nanocapsules prepared from preformed polymers as active substances carriers is presented. This entails a general review of the different preparation methods: nanoprecipitation, emulsion-diffusion, double emulsification, emulsion-coacervation, polymer-coating and layer-by-layer, from the point of view of the methodological and mechanistic aspects involved, e...

Double emulsions are highly structured fluids consisting of emulsion drops that contain smaller droplets inside. Although double emulsions are potentially of commercial value, traditional fabrication by means of two emulsification steps leads to very ill-controlled structuring. Using a microcapillary device, we fabricated double emulsions that contained a single internal droplet in a core-shell...

Double emulsions are useful in a number of biological and industrial applications in which it is important to have an aqueous carrier fluid. This paper presents a polydimethylsiloxane (PDMS) microfluidic device capable of generating water/oil/water double emulsions using a coaxial flow focusing geometry that can be fabricated entirely using soft lithography. Similar to emulsion devices using gl...
