Evaluation of behavior of adsorbed layers of protein-surfactant mixture at the air-water interfaces have recently received great attention due to their wide applications in food and pharmaceutical industries. In this research, qualitative study of surface activity of two kinds of proteins, Beta-Lactoglobulin (BLG) and Beta-Casein (BCS), non-ionic surfactant of C 10 DMPO, and the mixtures of them in different concentrations at the air-water interface is investigated using rising bubble method. The similarity between measured local velocity profiles can be due to the fact that all mentioned materials are surface-active one and could create the Marangoni effect and develop a dynamic adsorption layer. As there is no significant interaction between the protein and surfactant molecules, stable complex structures cannot be formed in the protein-C10DMPO mixture. The mixture velocity profile is more similar to that of the surfactant which is a result of replacement of protein molecules or complexes with free surfactant at the bubble interface. It is found that the mixture of non-ionic surfactant with BCS has a bit synergetic effect while for its mixture with BLG, a negative synergy is observed which is resulted from the shape of protein.

The development and implementation of transient heat transfer characteristics of nanofluids in energy management were studied. Ultrasonic-assisted SiO2/water nanofluids with 0.1–1.5 wt. % were prepared using polyvinyl alcohol (PVA) surfactant. The stability of nanofluids was tested and confirmed using zeta potential and light absorbance measurement. Thermophysical properties of nanofluid were investigated at various weight concentrations from 0.1 to 1.5 wt. % in a temperature range of 25–70°C. Transient heat transfer characteristics of nanofluids were examined. Thermophysical properties were enhanced by adding nanoparticles to base fluid. A major enhancement in transient heat transfer characteristics was obtained by applying SiO2/water nanofluids. The convective heat transfer coefficient (CHTC) was increased up to 2.37 times compared to water. The heat absorbance efficiency of the system is increased by a maximum of 24.54%. Finally, a new CHTC correlation has been proposed.
