Abstract
A simple, fast, and contactless alternative for the generation of nanodroplets in solution is to apply light to stimulate their formation at a surface. In this work, a light-driven mechanism for the generation of nanodroplets is demonstrated by using a porous membrane. The membrane is placed at the interface between oil and water during the nanodroplet generation process. As light illuminates the membrane a photothermal conversion process induces the growth and release of water vapor bubbles into the aqueous phase. This release leads to the fluctuation of local pressure around the pores and enables the generation of oil nanodroplets. A computational simulation of the fluid dynamics provides insight into the underlying mechanism and the extent to which it is possible to increase nanodroplet concentrations. The ability to form nanodroplets in solutions without the need for mechanical moving parts is significant for the diverse biomedical and chemical applications of these materials.

Abstract
:
Recent trends in research and investigation on nanoemulsion based products is the result of
many reasons such as food security as a global concern, increasing demand for highly efficient food and
agricultural products and technological need for products with the ability of manipulation and optimization
in their properties. Nanoemulsions are defined as emulsions made up of nano sized droplets dispersed
in another immiscible liquid which exhibit properties distinguishing them from conventional
emulsions and making them suitable for encapsulation, delivery and formulations of bioactive ingredients
in different fields including drugs, food and agriculture. The objective of this paper is to present a general
overview of nanoemulsions definition, their preparation methods, properties and applications in food and
agricultural sectors. Due to physicochemical properties of the nanoemulsion composition, creating nanosized
droplets requires high/low energy methods that can be supplied by special devices or techniques.
An overview about the mechanisms of these methods is also presented in this paper which are commonly
used to prepare nanoemulsions. Finally, some recent works about the application of nanoemulsions in
food and agricultural sectors along with challenges and legislations restricting their applications is discussed
in the last sections of the current study.

Abstract
A study on the chemical stability of anodic alumina membranes and their performance in long-term water and organic solvent permeation experiments is reported. Anodic alumina possesses high stability for both protonic and aprotonic organic solvents. However, serious degradation of the membrane occurs in pure water, leading to a drastic decrease of permeance (over 20% of the initial value after the passing of 0.250 m3/m2 of pure water). The drying of the membrane induces further permeance drop-off. The rate of membrane degradation strongly depends on the pH of the penetrant solution and increases in basic media. According to 27Al NMR and thermogravimetry results, the degradation of the membranes is associated with the dissolution of water-soluble [Al13O4(OH)24(H2O)12]7+ polyhydroxocomplexes and their further redeposition in the form of [Al(OH)4]-, resulting in channels blocking. This process intensifies in basic pH due to the high positive charge of the anodic alumina surface. An approach for improving anodic aluminum oxide stability towards dissolution in water by carbon CVD coating of the membrane walls is suggested.
