Microgels stand out as compelling alternatives to traditional emulsifiers in Pickering emulsions, owing to their unique deformability and responsiveness, distinguishing them from rigid particles and conventional surfactants. In this review, we provide an overview of recent advancements and breakthroughs in microgel synthesis and the stabilization of Pickering emulsions using microgels. Additionally, we discuss the underlying stabilization mechanisms of microgel-stabilized emulsions, elucidating the influencing factors such as microgel properties, environmental conditions, and interfacial structures that significantly impact emulsion stability. Given these recent achievements, we summarize and highlight the promising applications associated with diverse Pickering emulsion systems stabilized by tailored microgels, including interfacial catalysis, functional foods, vaccine adjuvants, stimuli-responsive colloidosomes, and droplet manipulation. Conclusively, we identify the existing research gaps in microgel studies and propose future directions, emphasizing the need for the rational design of microgels, comprehensive mechanism studies of microgel-stabilized emulsions, and the formation of next-generation Pickering emulsions.

微凝胶具有独特的可变形性和响应性,有别于刚性颗粒和传统表面活性剂,因此在皮克林乳液中是传统乳化剂的理想替代品。在本综述中,我们将概述微凝胶合成和使用微凝胶稳定皮克林乳液方面的最新进展和突破。此外,我们还讨论了微凝胶稳定乳液的基本稳定机制,阐明了微凝胶特性、环境条件和界面结构等对乳液稳定性有重大影响的因素。鉴于这些最新成果,我们总结并强调了与定制微凝胶稳定的各种皮克林乳液体系相关的前景广阔的应用,包括界面催化、功能食品、疫苗佐剂、刺激响应胶体和液滴操纵。最后,我们指出了微凝胶研究中现有的研究空白,并提出了未来的研究方向,强调了合理设计微凝胶、全面研究微凝胶稳定乳液的机理以及形成下一代皮克林乳液的必要性。

Microfluidic techniques have emerged as powerful tools to unveil dynamic processes occurring during foam and emulsion production, and instabilities during their lifetime (coalescence and digestion), and to gain detailed insights in interfacial effects at (sub)millisecond time scales, including but not limited to, interfacial adsorption (i.e. dynamic interfacial/surface tension) and interfacial rheology. These insights are pivotal in connecting the interfacial effects to dynamic processes as they would occur during emulsion/foam production. We highlight the importance of conducting research at relevant time scales.

微流控技术已成为揭示泡沫和乳液产生过程中的动态过程及其生命周期中的不稳定性(凝聚和消解)的有力工具,并可详细了解(亚)毫秒级时间尺度上的界面效应,包括但不限于界面吸附(即动态界面/表面张力)和界面流变学。这些见解对于将界面效应与乳液/泡沫生产过程中的动态过程联系起来至关重要。我们强调在相关时间尺度上开展研究的重要性。

This paper reviews the literature on various biosurfactant mixtures used to obtain foams. The interactions between different biosurfactants, biosurfactants, and synthetic surfactants, biosurfactants' interactions with various additives (as non-surface-active macromolecules or particles), and the impact of pH and ionic strength variations on adsorption processes, foamability, foam stability, and rheology are discussed. Biosurfactants are natural and synthetic compounds that can facilitate the process of foam formation and stabilisation; they are an alternative to classical surfactants. Research on such materials will allow the development of innovative foaming technologies that minimise the negative environmental effects of foaming compounds without losing the properties of the final product.

The primary objective of this review is to consolidate our current understanding of the factors controlling the foamability of surfactant solutions under hydrodynamic conditions realized in various laboratory tests. In particular, two regimes of foam generation are considered: at low surfactant concentrations where the coalescence between the bubbles plays a crucial role, and a high surfactant concentration range where the hydrodynamic conditions are much more important for the final outcome of foaming. The review discusses the role of surfactant concentration, dynamic surface coverage, and surface forces acting between film surfaces for the foam generated in the surfactant-poor regime. Additionally, the interplay between the hydrodynamic conditions and the viscosity of the formed foams in the surfactant-rich regime is also discussed.

本综述的主要目的是巩固我们目前对控制表面活性剂溶液在各种实验室测试中实现的流体力学条件下发泡性的因素的理解。其中特别考虑了泡沫产生的两种情况:在表面活性剂浓度较低的情况下,气泡之间的凝聚起着关键作用;而在表面活性剂浓度较高的情况下,流体力学条件对最终的发泡结果更为重要。综述讨论了表面活性剂浓度、动态表面覆盖率和薄膜表面之间的表面力对贫表面活性剂条件下产生的泡沫所起的作用。此外,还讨论了在表面活性剂丰富的条件下,流体动力学条件与所形成泡沫的粘度之间的相互作用。

Ordered porous materials (OPMs) are defined according to pore size, where ordered macropores (>50 nm) govern transport of fluids and mesopores (>2 nm, <50 nm) and micropores (<2 nm, IUPAC definitions) control molecular or ionic interactions. The growing importance of sustainable materials has incentivized the development of biobased OPMs (bioOPMs) with pore sizes ranging from 0.3 nm–9 nm and 1 μm–500 μm. Synthesizing bioOPMs typically involves aqueous solutions and suspensions which require a thorough understanding of biobased precursor-water interactions. Emerging approaches in templating based on liquid foams, breath-figure, and micelles are pivotal for achieving ordered assemblies, with solidity and consolidation occurring through water removal. This review describes recent advances in the design and utilization of bioOPMs, particularly those produced by water-based templating. It also highlights notable exceptions to water-based synthesis and identifies gaps in the science and technology of bioOPMs, offering perspectives on future developments in the field.

有序多孔材料(OPMs)是根据孔径大小来定义的,其中有序大孔(50 nm)控制流体的传输,中孔(2 nm,50 nm)和微孔(2 nm,IUPAC 定义)控制分子或离子的相互作用。可持续材料的重要性与日俱增,推动了孔径范围为 0.3 nm-9 nm 和 1 μm-500 μm 的生物基 OPMs(bioOPMs)的发展。合成生物OPMs 通常需要水溶液和悬浮液,这就要求对生物基前驱体与水的相互作用有透彻的了解。新出现的基于液体泡沫、呼吸结构和胶束的模板化方法对于实现有序组装至关重要,通过脱水可实现稳固和固结。本综述介绍了设计和利用生物有机聚合物的最新进展,特别是通过水基模板法生产的生物有机聚合物。它还强调了水基合成的显著例外,并指出了生物OPMs 科学和技术方面的差距,对该领域的未来发展提出了展望。

This paper reviews the literature on various natural and synthetic biosurfactants, which can facilitate the process of foam formation and stabilisation. Biosurfactants are an alternative to classical surfactants. For example, proteins, through their stabilising properties, can be used both in the food industry and in cosmetics, and this confirms their versatile properties and application in many areas of industry. Sugar-based foaming agents, on the other hand, are characterised by their ability to maintain high foam stability, and their natural origin and biodegradability are attractive substitutes for classical compounds of this type. This review aims to compare the effects of various compounds on the properties and stability of foams. Research on such materials will allow the development of innovative foaming technologies that minimise the negative environmental impacts of foaming compounds without losing the properties of the final product.

Predicting the behavior and fate of redox-sensitive trace elements (TEs; e.g. As, U, Cu, Cr) in natural systems is challenging. Colloids have been reported to control TEs speciation and catalyze TEs redox reactions in many aquatic environments. We hypothesize that the lack of accurate thermodynamic models that account for the role of colloids in TEs speciation explains our inability to predict their redox state distribution in the environment. The slow evolution of the colloidal compartment in response to the prevailing bio/hydro/pedo/climatological conditions need to be decoupled from the fast TEs redox reactions promoted by colloidal surfaces. Further progress is hampered by experimental and theoretical challenges associated with capturing the extreme physical and chemical heterogeneity of colloids, their metastable structures, and their dynamic transformation behavior.

预测自然系统中对氧化还原反应敏感的微量元素(如砷、铀、铜、铬)的行为和归宿具有挑战性。据报道,在许多水生环境中,胶体控制着痕量元素的标本化,并催化痕量元素的氧化还原反应。我们假设,由于缺乏准确的热力学模型来解释胶体在 TEs 分化中的作用,所以我们无法预测它们在环境中的氧化还原状态分布。需要将胶体与胶体表面所促进的快速 TEs 氧化还原反应分离开来,以了解胶体区块随当时的生物/水/气旋/气候条件而发生的缓慢演变。在捕捉胶体的极端物理和化学异质性、其可蜕变结构及其动态转化行为方面所面临的实验和理论挑战阻碍了进一步的研究进展。

Compared to conventional mesoporous silica nanoparticles (MSNs) with ordered porous structures, hierarchical MSNs (HMSNs) have attracted increasing research interests in biological fields, owing to their highly porous structures with multiple distinct interfaces, which create more possibilities to explore complex biological realms.

与具有有序多孔结构的传统介孔二氧化硅纳米粒子(MSNs)相比,分层介孔二氧化硅纳米粒子(HMSNs)因其具有多个不同界面的高多孔结构,为探索复杂的生物领域创造了更多可能性,因而在生物领域吸引了越来越多的研究兴趣。然而,由于其结构的复杂性,要可控地组装出具有所需纳米结构和明确颗粒特性的 HMSNs 具有挑战性。在此,我们回顾了通过控制表面活性剂纳米结构来设计 HMSNs 的研究进展,并讨论了其合成指导原则和形成机制。根据 HMSNs 的结构特征,总结了相应的生物应用(如大分子封装、药物释放、生物界面粘附、免疫细胞活化和刺激响应目标运动),强调了结构-活性关系的重要性。此外,还就 HMSNs 的表征和扩展应用提出了挑战和未来展望。

All personal and industrial cleaning sectors search for environmentally friendly methods to clean contaminated solid surfaces. Having relied for a long time on chemical and physico-chemical means with non-negligible environmental impact, these sectors are increasingly exploring the use of physical phenomena to improve cleaning efficiency. We summarise here recent progress in the area of cleaning methods that exploit the physical properties of liquid interfaces created by liquid menisci, bubbles, drops or foams. The high energy of these interfaces leads to a complex interplay between (1) interfacial forces, (2) viscous stresses created by flow fields under confinement, and (3) the capacity to adsorb solid and liquid contaminations. In appropriately designed cleaning processes, this interplay can reach an astounding efficiency, in many cases even with pure water, i.e. in the absence of any detergent. We will also show that whilst foams have always been assumed to be a mere side product of cleaning processes, recent research puts in evidence that they can actually be highly efficient cleaning agents, provided that their physical properties are properly chosen. We discuss a wide range of examples in which different interface-based cleaning methods have been investigated, including solid and liquid contaminations, or biological contaminations (bacteria, biofilms and biofouling).

所有个人和工业清洁部门都在寻找环保方法来清洁受污染的固体表面。长期以来,这些行业一直依赖于对环境造成不可忽视影响的化学和物理化学方法,现在正越来越多地探索利用物理现象来提高清洁效率。在此,我们总结了利用液膜、气泡、液滴、泡沫或乳液所形成的液体界面的物理特性的清洁方法领域的最新进展。这些界面的高能量导致了以下三者之间复杂的相互作用:(1) 界面力;(2) 流场在限制条件下产生的粘性应力;(3) 吸附固体和液体污染物的能力。在设计得当的清洁过程中,这种相互作用可以达到惊人的效率,在许多情况下,即使是纯水,即不使用任何清洁剂。我们还将说明,虽然泡沫一直被认为只是清洁工艺的副产品,但最近的研究证明,只要泡沫的物理特性选择得当,它们实际上可以成为高效的清洁剂。我们将讨论各种基于界面的清洁方法,包括固体和液体污染物或生物污染物(细菌、生物膜和生物污垢)。
