Abstract:
... Biopolymer nanoparticles are a versatile group of colloidal delivery systems with numerous food and pharmaceutical applications. Various methods have been employed for the fabrication of these nanoparticles. However, many conventional methods are infeasible for practical utilization because they involve multiple steps and involve energy-, time- and, material-consuming methods. Microemulsion drople ...

Abstract:
... We developed a rapid and simple method to fabricate microfluidic non-planar axisymmetric droplet generators using 3D printed fittings and commercially available components. 3D printing allows facile fabrication of microchannels albeit with limitations in the repeatability at low resolutions. In this work, we used 3D printed fitting to arrange the flow in the axisymmetric configuration, while the c ...

Abstract:
... The lubrication effect of bicontinuous microemulsions describes a facilitated flow along hydrophilic planar surfaces because the fluid forms lamellar domains that can slide off along each other much better than randomly ordered domains. The applicability of this effect is based on the prerequisite of the lamellar structure not being destroyed by external shear-fields. In this paper, we demonstrate ...

Abstract:
... Asphaltenes tend to aggregate in different structures depending on the aromatic content of the oil phase. The different aggregates adsorb at the interface as some kind of lipophilic surfactant, which tends to stabilize water-in-oil emulsions. Hydrophilic demulsifier molecules are added to combine with asphaltenes until the optimum formulation is attained at HLD = 0, thus resulting in the emulsion ...

Abstract:
... The use of ultrasound (US) has proven to be an effective tool in the preparation of emulsions. However, the cavitation phenomenon leads to an increase in temperature, which can affect the emulsion stability and the texture. Thus, different US operating modes (degas, normal, and sweep) were applied in meat emulsions for 5.5 min, at 25 kHz frequency and 60% amplitude, and the temperature behavior, y ...
