“…[2]. The major findings have been: (a) the surface tension isotherm has two plateau portions; (b) the surface dilational elasticities pass through a sequence of maxima and minima; (c) the onset of characteristic 'unstable' black patterns in draining microscopic foam films is registered; (d) a relative stabilization of the draining films is observed.…”

“…C 12 E 3 is chosen for two reasons. First, to check if within the premicellar concentration range specific peculiarities between adsorption layer properties and foam film drainage characteristics could be detected and juxtaposed to the anomalies already established for the higher homolog (C 12 E 4 ) [2]. Second, the length of the hydrophobic tail and all the rest conditions (temperature, added electrolyte) being the same, the goal is to add new knowledge about the specific effect of the size of the hydrophilic head on the overall interfacial and bulk properties of the investigated systems.…”

“…It has been clarified in [15,16 ] how the surfactant adsorption layer properties are related to the course of the drainage parameters of microscopic foam films in the special case of aqueous solutions of the ionic and non-ionic amphiphiles, containing premicellar nanostructures. It was established that in the premicellar concentration domain considerable irregularities of the adsorption layer properties are observed: plateau and kink regions are registered in the experimental surface tension isotherm along with unusual changes of the surface rheological characteristics.…”

Interfaces can be called Smart and Green (S&G) when tailored such that the required technologies can be implemented with high efficiency, adaptability and selectivity. At the same time they have also to be eco-friendly, i.e. products must be biodegradable, reusable or simply more durable. Bubble and drop interfaces are in many of these smart technologies the fundamental entities and help develop smart products of the everyday life.Significant improvements of these processes and products can be achieved by implementing and manipulating specific properties of these interfaces in a simple and smart way, in order to accomplish specific tasks. The severe environmental issues require in addition attributing ecofriendly features to these interfaces, by incorporating innovative , or, sometime, recycle materials and conceiving new production processes which minimize the use of natural resources and energy. Such concept can be extended to include important societal challenges related to support a sustainable development and a healthy population.The achievement of such ambitious targets requires the technology research to be supported by a robust development of theoretical and experimental tools, needed to understand in more details the behavior of complex interfaces. A wide but not exhaustive review of recent work concerned with green and smart interfaces is presented, addressing different scientific and technological fields. The presented approaches reveal a huge potential in relation to various technological fields, such as nanotechnologies, biotechnologies, medical diagnostics, new or improved materials.

Protein foams are common to foods, such as meringue, whipped cream and mousses. Stability is a challenging issue determined by fat and sugar content. We hypothesize that acetyl‐triacylglycerols (acetyl‐TAG) that possess sn‐3 acetate group with high oleic content can provide stability to the foam at reduced sugar concentrations by increasing the surface viscosity and minimizing serum drainage. A fractional factorial Box‐Wilson design was used to investigate the effects of whey protein concentration (WPI) (2–10 wt%), sucrose concentration (SC) (10–30 wt%) and acetyl‐TAG concentration (ATC) (0–1 wt%) on overrun (FO), stability against serum drainage (FD) and surface dilatational rheology. Each response was analyzed by linear regression model fitting and a backward elimination algorithm for significance (α = 0.01). FO was significantly affected (p < 0.01) by WPI and ATC, but not sucrose concentration. The optimum overrun (nearly 700%) was obtained at 9 wt% WPI and 0.6 wt% ATC. Drainage and viscoelastic properties were significantly (p < 0.01) affected by all process variables. Dynamic complex modulus (|E|) as measured using an optical tensiometer was around 30–40 mN/m when acetyl‐TAG was higher than 0.5 wt%. Our findings indicated that the acetyl‐TAG can be used to enhance the stability of protein foams in reduced sugar food products, however, not at high sugar concentrations (30 wt%).
