“…The AS had an interfacial tension (IFT) of 53 AE 0.1 mN m À1 . Similar to short n-aminopentane molecules, 56 the surface activity of the AS can be related to the amphiphilic structure of the molecule, consisting of hydrophobic methyl-and propyl-groups connected through silicon atom and hydrophilic amino-group ( Fig. SI.1a, ESI †).…”

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.

Foams that respond to external stimuli are a new type of highly functional soft matter and an emerging research subject in the field of materials and colloid science. Herein, we report a new way to control foam stability using light irradiation. This unconventional approach involves a combination of the thermal response of a fatty acid and the ability of carbon black to convert light stimulus to heat. This simple system features both high foamability and high foam stability, but can easily be destroyed by light. Upon exposure to UV or solar illumination, the carbon black particles absorb light causing an increase in temperature inside the foam lamella. This results in a transition of the fatty acid assemblies from tubes, which stabilize the foam films, to micelles, leading to rapid foam destabilization. The foam destabilization rate under UV irradiation was correlated to foam liquid fraction, fatty acid concentration, as well as carbon black concentration. Our approach for the formulation of photo-thermo-responsive foams could be easily generalized and extended to magnetic particles, giving rise to the first foams exhibiting thermo-photo-magneto-tuneable stability. Such multi-stimuli responsive systems can find applications in diverse industries requiring highly stable systems which can be destroyed on-demand.
