Forces at superhydrophobic and superamphiphobic surfaces
Publication date: Available online 10 December 2019Source: Current Opinion in Colloid & Interface ScienceAuthor(s): Mimmi Eriksson, Agne SwerinAbstractForces exerted at surfaces and interphases due to formation of gaseous (air or vapor) bridges describe the extreme liquid-repellence in superhydro- and amphiphobicity. The neighboring research areas oγAf liquid capillary bridges and that of interactions between hydrophobic surfaces are highly valuable reference systems. We review recent findings with particular focus on the three-phase contact line and surface forces. While macroscopic contact angles (>150°), low contact a...

Structure-Activity Relationship of Cationic Surfactants as Antimicrobial Agents
Publication date: Available online 6 December 2019Source: Current Opinion in Colloid & Interface ScienceAuthor(s): Chengcheng Zhou, Yilin WangAbstractCationic surfactants are widely used as antimicrobial agents in various fields. However, the widespread use of cationic surfactants has caused huge accumulation in environment, triggering the emergence of bacterial resistance. Besides, due to the strong cytotoxicity, most of cationic surfactants are limited in practical applications. Therefore, constant attention has been paid on how to rationally design the surfactants for achieving highly efficient antimicrobial activity at...

Surface Forces between Bottle-Brush Polymer Layers
Publication date: Available online 6 December 2019Source: Current Opinion in Colloid & Interface ScienceAuthor(s): Xiaoyan LiuAbstractIn this review, I summarize recent experimental investigations of surface and friction forces between bottle-brush structure macromolecules including biolubricants and biomimetic ones by direct force measurements. I also discuss recent experimental investigations of synergy in lubrication in which a question, “How do lubricants act together?”, is aimed to be answered. Lastly, challenges and opportunities for developing efficient lubricating systems are outlined. (Source: Current Opinion ...

Progress in nuclear magnetic resonance studies of surfactant systems
Publication date: February 2020Source: Current Opinion in Colloid & Interface Science, Volume 45Author(s): Xingcen Liu, Qun Yu, Aixin Song, Shuli Dong, Jingcheng HaoAbstractNuclear magnetic resonance (NMR), as a powerful technology, is widely used to characterize the physicochemical properties of surfactants in solution. As a sensitive technique to molecular environment, NMR is beyond the reach of other spectral methods in surfactant systems. Recent years, intensive investigations of surfactants by NMR were reported but not well summarized; therefore, we highlight these significant progresses, which may shed light on the c...

Ion–micelle interactions and the modeling of reactivity in micellar solutions of simple zwitterionic sulfobetaine surfactants
Publication date: December 2019Source: Current Opinion in Colloid & Interface Science, Volume 44Author(s): Gustavo T.M. Silva, Frank H. QuinaAbstractAqueous micellar solutions of sulfobetaine surfactants provide a simple physical–chemical system for investigating the origin and consequences of the specific interactions of anions with a model zwitterionic interface. Studies of ground-state reaction kinetics in micellar solutions of these surfactants provide a window into some of the more intriguing aspects of both anion and cation interactions with a zwitterionic micelle surface. Recent molecular dynamics simulations pain...

Entropy Studies in Interface Science: an Ageless Tool
Publication date: Available online 15 November 2019Source: Current Opinion in Colloid & Interface ScienceAuthor(s): Louise Deschênes, Johannes LyklemaAbstractIt is possible to obtain (excess) interfacial entropies from the temperature dependence of some characteristic surface parameter. Such excess entropies contain much valuable information. Their studies lead to deeper insight into the interfacial properties. In some cases, quite unexpected results are obtained. In the present paper, we shall consider three illustrations: (1) the surface excess entropy of the electrical double layer on silver iodide, (2) the surface exc...

Stimuli-responsive polymer/metal composites: from fundamental research to self-regulating devices
Publication date: Available online 16 November 2019Source: Current Opinion in Colloid & Interface ScienceAuthor(s): Dikran Boyaciyan, Regine von KlitzingAbstractThe review focuses on stimuli–responsive composite materials consisting of polymers and metals. Special attention is drawn to the conversion of one external stimulus into another one, which leads to a cascade effect on the interaction with the vicinity. Beside fundamental aspects concepts for technical applications of those polymer/metal composites are presented.Graphical abstract (Source: Current Opinion in Colloid and Interface Science)

The role of surface forces in mineral flotation
Publication date: Available online 14 November 2019Source: Current Opinion in Colloid & Interface ScienceAuthor(s): Yaowen Xing, Mengdi Xu, Xiahui Gui, Yijun Cao, Martin Rudolph, Hans-Jürgen Butt, Michael KapplAbstractFlotation is an interfacial separation technique, which plays a major role in mineral processing industry. It separates particles according to their wetting properties. In flotation pulp, particles and bubbles are highly dispersed in aqueous medium and in the presence of various flotation reagents. Almost all interfacial interactions including inter-particle, inter-bubble, and bubble-particle interactions in...

Supramolecular Surfactants Derived from Calixarenes
Publication date: Available online 14 November 2019Source: Current Opinion in Colloid & Interface ScienceAuthor(s): L. García-Rio, Nuno BasilioAbstractSupramolecular surfactants self-aggregate via noncovalent interactions. The process is rapid and reversible which makes them potentially useful for the design of stimulus-response systems. Here we focus on host:guest interactions using calixrenes as molecular receptors. Calixarenes are a family of molecular receptors because of their ease of preparation and post-modification. The calixarenes discussed here are prepared with molecules that cannot self-aggregate, but when com...
