Optimising the oil phases of aluminium hydrogel-stabilised emulsions for stable, safe and efficient vaccine adjuvant

《化学科学与工程前沿（英文）》 2022年 第16卷 第6期   页码 973-984 doi: 10.1007/s11705-021-2123-1

摘要： To increase antibody secretion and dose sparing, squalene-in-water aluminium hydrogel (alum)-stabilised emulsions (ASEs) have been developed, which offer increased surface areas and cellular interactions for higher antigen loading and enhanced immune responses. Nevertheless, the squalene (oil) in previous attempts suffered from limited oxidation resistance, thus, safety and stability were compromised. From a clinical translational perspective, it is imperative to screen the optimal oils for enhanced emulsion adjuvants. Here, because of the varying oleic to linoleic acid ratio, soybean oil, peanut oil, and olive oil were utilised as oil phases in the preparation of aluminium hydrogel-stabilised squalene-in-water emulsions, which were then screened for their stability and immunogenicity. Additionally, the underlying mechanisms of oil phases and emulsion stability were unravelled, which showed that a higher oleic to linoleic acid ratio increased anti-oxidative capabilities but reduced the long-term storage stability owing to the relatively low zeta potential of the prepared droplets. As a result, compared with squalene-in-water ASEs, soybean-in-water ASEs exhibited comparable immune responses and enhanced stability. By optimising the oil phase of the emulsion adjuvants, this work may offer an alternative strategy for safe, stable, and effective emulsion adjuvants.

Gas marbles: ultra-long-lasting and ultra-robust bubbles formed by particle stabilization

《化学科学与工程前沿（英文）》   页码 1681-1687 doi: 10.1007/s11705-022-2180-0

摘要： Bubbles and foams are ubiquitous in daily life and industrial processes. Studying their dynamic behaviors is of key importance for foam manufacturing processes in food packaging, cosmetics and pharmaceuticals. Bare bubbles are inherently fragile and transient; enhancing their robustness and shelf lives is an ongoing challenge. Their rupture can be attributed to liquid evaporation, thin film drainage and the nuclei of environmental dust. Inspired by particle-stabilized interfaces in Pickering emulsions, armored bubbles and liquid marble, bubbles are protected by an enclosed particle-entrapping liquid thin film, and the resultant soft object is termed gas marble. The gas marble exhibits mechanical strength orders of magnitude higher than that of soap bubbles when subjected to overpressure and underpressure, owing to the compact particle monolayer straddling the surface liquid film. By using a water-absorbent glycerol solution, the resulting gas marble can persist for 465 d in normal atmospheric settings. This particle-stabilizing approach not only has practical implications for foam manufacturing processes but also can inspire the new design and fabrication of functional biomaterials and biomedicines.

Danae Gonzalez Ortiz, Celine Pochat-Bohatier, Julien Cambedouzou, Mikhael Bechelany, Philippe Miele

《工程（英文）》 2020年 第6卷 第4期   页码 468-482 doi: 10.1016/j.eng.2019.08.017

摘要：

近年来，Pickering乳液因其易于制备和强稳定性的特点引起了人们的广泛关注。与经典乳液不同，在Pickering乳液中，位于液体界面处的固体微粒或纳米颗粒被用作稳定剂，而不是表面活性剂，从而增加了液滴的寿命。此外，与由表面活性剂稳固的乳液相比，Pickering乳液具有更高的稳定性、更低的毒性和刺激反应性。因此，它们可以被认为是具有广泛用途的理想成分，如光催化和新材料的制备。此外，纳米颗粒的形貌对Pickering乳液的稳定性及其潜在利用率有很大的影响。在本文中，我们回顾了近年来关于Pickering乳液的一些研究成果，重点介绍了纳米颗粒的形态，如立方体、椭球体、纳米片、球体、圆柱体、棒状、花生状，如何影响这种乳液的类型和稳定性，以及它们在抗菌活性、蛋白质识别

The construction of pseudo-Janus silica/surfactant assembly and their application to stabilize Pickering

《化学科学与工程前沿（英文）》 2022年 第16卷 第7期   页码 1101-1113 doi: 10.1007/s11705-021-2095-1

摘要： Nanoparticles with high surface energy and chemical activity have drawn substantial attention in petroleum industry. Recently, Janus nanoparticles exhibited tremendous potential in enhanced oil recovery (EOR) due to their asymmetric structures and properties. In this study, a series of amphiphilic pseudo-Janus@OTAB (PJ@C18) nanoparticles with different concentrations of stearyltrimethylammoium bromide (OTAB) were successfully fabricated. The structures and properties of PJ@C18 were characterized by Fourier transform infrared spectroscopy and ζ-potential measurements. Based on the emulsification experimental results, the interaction models and the self-assembly behavior between hydrophilic nanoparticles (SiO2@NH2) and OTAB molecules at the oil/water interface were proposed, which was further confirmed via the measurements of the contact angle and dynamic interfacial tension. Interestingly, it was found that the change of pH value from 7.5 to 4.0 caused the type reversal of the PJ@C18-1000 stabilized Pickering emulsions. Furthermore, the PJ@C18-1000 stabilized Pickering emulsion system with excellent salt and temperature tolerances (10000 mg∙L–1, 90 °C) significantly improved the oil recovery in the single-tube (more than 17%) and double-tube (more than 25%) sand pack model flooding tests. The findings of this study could help to better understand the construction mechanism of pseudo-Janus silica/surfactant assembly and the potential application of PJ@C18-1000 stabilized Pickering emulsions for EOR.

Importance of emulsions in crystallization—applications for fat crystallization

Sandra PETERSEN, K. CHALEEPA, Joachim ULRICH

《化学科学与工程前沿（英文）》 2013年 第7卷 第1期   页码 43-48 doi: 10.1007/s11705-013-1309-6

摘要： Emulsions and crystallization are two independent research topics which normally do not overlap although a combination of the two could be applicable to many areas. Here, the importance of emulsions in the field of fat crystallization is described. Three applications with industrial relevance were chosen for investigation: fat fractionation, the solidification of phase change materials and solid lipid nanoparticles. For fat fractionation and phase change materials, emulsification can be applied as a tool to improve the fat crystallization process, and thus the product quality of the crystallized fat. Furthermore, the use of emulsification creates new application fields such as solid lipid nanoparticles in the area of fat crystallization.

Performance and emission characteristics of a diesel engine operating on different water in diesel emulsion

Seyed Saeed HOSEINI, Mohammad Amin SOBATI

《能源前沿（英文）》 2019年 第13卷 第4期   页码 636-657 doi: 10.1007/s11708-019-0646-7

摘要： The nitrogen oxide (NO ) release of diesel engines can be reduced using water in diesel emulsion fuel without any engine modification. In the present paper, different formulations of water in diesel emulsion fuels were prepared by ultrasonic irradiation. The water droplet size in the emulsion, polydisperisty index, and the stability of prepared fuel was examined, experimentally. Afterwards, the performance characteristics and exhaust emission of a single cylinder air-cooled diesel engine were investigated using different water in diesel emulsion fuels. The effect of water content (in the range of 5%–10% by volume), surfactant content (in the range of 0.5%–2% by volume), and hydrophilic-lipophilic balance (HLB) (in the range of 5–8) was examined using Box-Behnken design (BBD) as a subset of response surface methodology (RSM). Considering multi-objective optimization, the best formulation for the emulsion fuel was found to be 5% water, 2% surfactant, and HLB of 6.8. A comparison was made between the best emulsion fuel and the neat diesel fuel for engine performance and emission characteristics. A considerable decrease in the nitrogen oxide emission (–18.24%) was observed for the best emulsion fuel compared to neat diesel fuel.

Porous ultrathin-shell microcapsules designed by microfluidics for selective permeation and stimuli-triggered release

《化学科学与工程前沿（英文）》   页码 1643-1650 doi: 10.1007/s11705-022-2201-z

摘要： Microcapsules are versatile delivery vehicles and widely used in various areas. Generally, microcapsules with solid shells lack selective permeation and only exhibit a simple release mode. Here, we use ultrathin-shell water-in-oil-in-water double emulsions as templates and design porous ultrathin-shell microcapsules for selective permeation and multiple stimuli-triggered release. After preparation of double emulsions by microfluidic devices, negatively charged shellac nanoparticles dispersed in the inner water core electrostatically complex with positively charged telechelic α,ω-diamino functionalized polydimethylsiloxane polymers dissolved in the middle oil shell at the water/oil interface, thus forming a porous shell of shellac nanoparticles cross-linked by telechelic polymers. Subsequently, the double emulsions become porous microcapsules upon evaporation of the middle oil phase. The porous ultrathin-shell microcapsules exhibit excellent properties, including tunable size, selective permeation and stimuli-triggered release. Small molecules or particles can diffuse across the shell, while large molecules or particles are encapsulated in the core, and release of the encapsulated cargos can be triggered by osmotic shock or a pH change. Due to their unique performance, porous ultrathin-shell microcapsules present promising platforms for various applications, such as drug delivery.

摘要：

由于硅阳极体积膨胀过大，无法在高能量密度电池中实现实际应用。研究人员一直专注于在阳极中添加黏结剂以限制体积膨胀，来解决这一问题，因为黏结剂的氢键和机械性能可以用来增强黏附力和适应硅阳极的体积变化。在这里，我们综合考虑了黏结剂的氢键、力学性能、稳定性以及与电解液的相容性，设计了一种富醚/酯/氟的复合聚合物P(TFEMA-co-IBVE)。该黏结剂配方具有优异的稳定性、黏结性和机械强度，能够适应硅电极体积的剧烈变化，表现出优异的电化学性能，面积容量高达5.4 mA∙h∙cm−2。这种新型聚合物设计可应用于下一代锂离子电池的其他电极材料。

《工程（英文）》 2023年 第23卷 第4期   页码 73-81 doi: 10.1016/j.eng.2022.02.017

摘要：

水-油界面不平衡是实现油包水乳液破乳的关键。传统膜通常是依赖较高的跨膜压力破坏界面平衡而实现破乳。本文提出了可自然、快速地破坏水-油界面平衡的“接触破乳”的概念，开发了一种对有机组分具有高通量的新型破乳分离膜。具体制备过程分为两步，首先通过真空辅助抽滤法在聚四氟乙烯（PTFE）基底上组装ZIF-8@rGO微球（ZGS）层，再采用聚二甲基硅氧烷（PDMS）交联溶液进行固定化处理。由于ZGS表面为微纳米阶层结构，所制备的ZIF-8@rGO@PDMS/PTFE（ZGPP）膜表面展现出超疏水性特性，当表面活性剂稳定的油包水乳液接触到膜表面时，微纳结构的超疏水膜表面会引起水-油界面不平衡。ZGPP膜对油包水乳液具有良好的分离破乳性能，在0.15 bar（15 kPa）的低跨膜压力下，分离效率可以达到99.57%，通量可达到2254 L·m‒2·h‒1，且对于表面活性剂稳定的纳米级甲苯水乳液（平均液滴尺寸为57 nm）的体系也可以实现破乳分离。“接触破乳”概念的提出有望为开发新一代油包水乳液分离的破乳膜提供新的思路。

A free-standing superhydrophobic film for highly efficient removal of water from turbine oil

Fan Shu, Meng Wang, Jinbo Pang, Ping Yu

《化学科学与工程前沿（英文）》 2019年 第13卷 第2期   页码 393-399 doi: 10.1007/s11705-018-1754-3

摘要： A free-standing superhydrophobic film is prepared by sequentially dip-coating a commercially available filter paper with nano SiO suspension, epoxy emulsion, and octyltrimethoxysilane solution. A surface with micro- or nano-roughness is formed because SiO nanoparticles are uniformly and firmly adhered on the backbone of the filter paper by the cured epoxy resin. Furthermore, the surface energy is significantly reduced because of introducing octytrimethoxysilane. Such a surface structure makes the prepared film a superhydrophobic material. Due to its free-standing nature, this superhydrophobic film can be used to remove water from turbine oil by filtration. The efficiency of water removal is high (up to 94.1%), and the filtration process is driven solely by gravity without extra energy consumption. Because of the facile fabrication process and the high efficiency of water removal, this free-standing superhydrophobic film may find application in power industry.

MILP synthesis of separation processes for waste oil-in-water emulsions treatment

Zorka N. Pintarič,Gorazd P. Škof,Zdravko Kravanja

《化学科学与工程前沿（英文）》 2016年 第10卷 第1期   页码 120-130 doi: 10.1007/s11705-016-1559-1

摘要： This paper presents a novel synthesis method for designing integrated processes for oil-in-water (O/W) emulsions treatment. General superstructure involving alternative separation technologies is developed and modelled as a mixed integer linear programming (MILP) model for maximum annual profit. Separation processes in the superstructure are divided into three main sections of which the pretreatment and final treatment are limited to the selection of one alternative (or bypass) only, while within the intermediate section various combinations of different technologies in series can be selected. Integrated processes composed of selected separation techniques for given ranges of input chemical oxygen demand (COD) can be proposed by applying parametric analyses within the superstructure approach. This approach has been applied to an existing industrial case study for deriving optimal combinations of technologies for treating diverse oil-in-water emulsions within the range of input COD values between 1000 mg?L and 145000 mg?L . The optimal solution represents a flexible and profitable process for reducing the COD values below maximal allowable limits for discharging effluent into surface water.

摘要： Silica hollow microspheres containing phosphorous have been prepared by a sol-gel/emulsion method which uses tetraethoxysilane (TEOS) as the precursor for the SiO and phosphoric acid (H PO ) as the precursor for P O . The hollow structure forms an emulsion system which is composed of an oil phase (kerosene, sorbitan monooleate (Span 80)) and an aqueous phase (a viscous sol solution of ethanol, TEOS and H PO ). Some of the phosphorous remains in the final silica shell structure even after calcination at 650°C. The hollow structure of the P O -SiO (silicophosphate) was characterized by X-ray diffraction (XRD), polarized optical microscopy (POM), scanning electron microscopy (SEM), nitrogen adsorption measurement and Fourier transform infrared spectroscopy (FTIR).
