Estudi dels paràmetres de control de la primera etapa de la microencapsulació

Autor: Hernández Ponce, Sofia

La microencapsulació és un mètode en desenvolupament, així com una tècnica molt versatil i innovadora que pot ser utilitzada en molts àmbits. Aquest projecte s’ha basat en estudiar la primera etapa de la microencapsulació, analitzant els par

The wettability is one of the critical properties of the falling film type absorber, limiting the wetting area in the absorber, hence the total mass transfer performance. To achieve low values of wetting rate in the absorber is an interesting feature

Biosurfactant from Bacillus subtilis DS03: Properties and Application in Cleaning Out Place System in a Pilot Sausages Processing

Autor: Iana Cruz Mendoza, Mirian Villavicencio-Vasquez, Paola Aguayo, Diana Coello Montoya, Luis Plaza, María Romero-Peña, Ana M. Marqués, Jonathan Coronel-León

Publikováno v: Microorganisms; Volume 10; Issue 8; Pages: 1518

Microbial surfactants (MS) or biosurfactants (BS) are amphiphilic molecules composed of a hydrophilic and a hydrophobic segment, which align at the interface between polar and non-polar compounds, reducing the surface tension. BS production is develo

We present a series of experiments with droplets of aqueous cyclodextrin-surfactant solutions, in which the volume is reduced after the equilibrium spherical shape is reached. The final shape of the drop after this perturbation is found to be depende

A level-set model for two-phase flow with variable surface tension: Thermocapillary and surfactants

Autor: Balcázar Arciniega, Néstor, Rigola Serrano, Joaquim, Oliva Llena, Asensio

Publikováno v: 8th European Congress on Computational Methods in Applied Sciences and Engineering.

An unstructured conservative level-set method for two-phase flow with variable surface tension is introduced. Surface tension is a function of temperature or surfactant concentration on the interface. Consequently, the called Marangoni stresses induc

Oil-in-water nanoemulsions (NEs) are considered a suitable nanotechnological approach to improve the eye-related bioavailability of lipophilic drugs. The potential of cationic NEs is prominent due to the electrostatic interaction that occurs between
