W/O/W multi-structure emulsions were prepared by two-step method,to investigate the effect of different W/O emulsifier,anionic emulsifier as well as the first phase volume ratio on the formation and stability of multi-structure emulsions.The result indicated that ES-5300 is efficient in forming the homogeneous and stable W/O/W multi-structure emulsions which related to the emulsifier structure and low HLB value.Compared with other anionic emulsifier,sodium isostearoyl lactylate can product more stable multi-structure emulsions.However,the higher temperature stability was affected by the increasing of it.In addition,appropriate first phase volume ratio is critical to the stability of multi-structure emulsions.The multi-structure emulsions with better encapsulation efficiency and great performance in higher temperature was achieved when the first phase volume ratio equal to 1. 展开更多

Structure of emulsifiers or functionality and molecular weight determines its rheology, emulsification and stability of emulsion explosives. Rheology of typical emulsifiers was studied by automatic rheometer. Relations between rheology and structural properties of typical emulsifiers were analyzed. Experimental results show that viscosity of emulsifiers didn＇ t change with shear rate at room temperature and appeared properties of Newtonian fluid. Viscosity of different component emulsifiers declines with temperature in different modes. The change of strain doesn＇ t affect modu- lus of emulsifiers. Loss modulus increases linearly with the increase of frequency in oscillation and storage modulus does non-linearly. The higher the temperature is, the lower change amplitude of loss modulus with frequency will be. The emulsifiers with imide and amide functionality for emulsion explosives have better shear properties at high temperature and better shapingness and stability at room temperature than other emulsifiers with ester and Sorbin Monoleate （SMO） functionality. 展开更多

The phenolic emulsifiers used in emulsified asphalt of micro-surfacing, which was the most important tools in the road maintenance, were investigated by control technology. Many factors influencing this reaction were studied and three kinds of phenolic emulsifiers were prepared without catalyst in ethanol. The performance was researched that 2-（{2-[2-（2-Amino-ethylamino）-ethylamino]-ethyl-amino}-methyl）-4- nonyl-phenol （abbreviated as TETA） could be used in micro-surface. With addition of 0.5 % demulsifier, the mixing time was extended to 120 seconds obviously, and the cohesion torque （60 min） was 2.8 N＊m, which satisfied the opening traffic time shorter than 1 h. The wet track abrasion （6 d） was lower than 807 g/m2, with interracial modifier added, but the load wheel was increased with interfacial modifier increasing. When the TETA： demulsifier： interracial modifier =3：1：3, excellent performance was obtained and the experimental results met the International Slurry Surfacing Association （ISSA） standard. The synthesis process of this emulsifier is simple and the performance used in micro-surface was excellent, so this kind of emulsifier could have a better application future. 展开更多

Whole wheat bread is widely available worldwide,but it is always associated with less desirable dough processibility,small loaf volume,firm and gritty texture,and other distinctive attributes compared to white bread.Emulsifiers are commonly used to improve dough handling and baking quality during bread production.In present study,five emulsifiers(diacetyl tartaric acid esters of mono-and diglycerides(DATEM),polysorbate 80,sodium stearoyl lactylate(SSL),soy lecithin,and sucrose esters)were added during dough preparation of the whole wheat flour at 0.2%,0.5%,and 1.0%(flour weight basis).Dough rheological behavior and bread quality attributes,such as specific loaf volume and hardness,were measured.The results showed that DATEM,sucrose esters,and SSL increased the resistance to extension of the dough,whereas soy lecithin and polysorbate 80 increased the extensibility.Soy lecithin and polysorbate 80 were the only emulsifiers that significantly increased loaf volume compared to the control.Adding higher levels(1.0%)of sucrose esters,polysorbate 80,and SSL increased the formation of amylose-lipid complex and mitigate the crumb staling during storage.The results suggested that the emulsifiers could be applied to contribute to optimum functional quality of whole wheat bread. 展开更多

Surfactant food emulsifiers are among the most extensively used food additives.Like all authorized food additives,emulsifiers have been evaluated by risk assessors,who consider them as safe.However,there are growing concerns among scientists about their possible harmful effects on intestinal barriers and microbiota.It is also suggested that emulsifier consumption might be one of the main causes of the rising incidence of a number of diseases,such as allergic diseases,celiac disease,type I diabetes and Crohn’s disease.Moreover,it has recently been suggested that emulsifier consumption might contribute to the development of metabolic syndrome and can promote colitis-associated colorectal cancer also.This paper provides an overview of the current scientific knowledge on possible effects of surfactant emulsifiers on intestinal barriers and also of regulatory risk assessment approaches.Our main objective is to reveal the reasons for the discrepancies between the opinions of risk assessors and the scientific world.We would like to draw the attention of the academic world to the need of specific in vivo and/or clinical studies for each emulsifier in order to help risk assessors make adequate evaluations and rule out with certainty that authorized food emulsifiers pose a safety concern to consumers’health. 展开更多

Surfactants are indispensable in various industrial sectors;however,the poor biodegradability and environmental toxicity of synthetic surfactants have intensified the demand for sustainable alternatives.In this study,Bacillus velezensis DG5714 was isolated from an oil sludge-contaminated environment and comprehensively characterized in terms of its metabolic and genetic properties to validate its ecological safety and potential application as a biosurfactant-producing strain.The biosurfactant extracted from this strain was structurally identified as surfactin C.It exhibited exceptional surface activity,reducing the surface tension of water to 23.13 mN/m at a critical micelle concentration of 0.1 mg/mL.In addition,the biosurfactant demonstrated remarkable stability across wide ranges of pH(4-10),temperature(30-80℃),and salinity(3%-18%).Functional assessments revealed that its foaming and emulsifying abilities were comparable to those of conventional synthetic surfactants.Toxicity evaluations,including hemolysis assays,in vitro cytotoxicity tests,and in vivo phytotoxicity assays,confirmed its excellent biocompatibility and ecological safety.Overall,the biosurfactant derived from B.velezensis DG5714exhibits strong potential as a sustainable and effective alternative to synthetic surfactants owing to its excellent surface activity.In addition,this study presents a systematic approach for proposing sustainable alternatives to conventional synthetic surfactants. 展开更多

To reduce the environmental pollution associated with the construction of asphalt pavements,and to improve the current problems of insufficient stability,durability,and adaptability of cold mix asphalt(CMA),a cold mix emulsified asphalt(CMEA)was prepared by using emulsified asphalt,silane coupling agent,cement,plaster,and mineral powder.The basic properties of CMEA were evaluated through penetration,softening point,and ductility tests.The high-temperature rheological properties of CMEA were analyzed using dynamic shear rheometry(DSR).The microstructure of CMEA was assessed via fluorescence microscopy(FM)and Fourier transform infrared spectroscopy(FTIR)tests.Results indicate that the emulsion within the emulsified asphalt can be uniformly distributed in the form of particles,resulting in improved storage stability.Compared to the original emulsified asphalt,the addition of cement,plaster,or a combination of both shows better stability and deformation resistance.The CMEA with both the silane coupling agent and cement exhibits the optimal performance.This study provides new insights for the modification and application of CMA. 展开更多

In recent years,the amount of waste generated during milling has increased dramatically,and improper disposal poses a significant environmental challenge.To mitigate environmental pollution and enhance the road performance of emulsified asphalt cold recycled mixtures(ECRM),this study employed recycled asphalt pavement(RAP)and reclaimed inorganic binder stabilized aggregate(RAI)as dual recycled materials for ECRM preparation.The blending ratios of reclaimed base and surface layer mixtures significantly influence ECRM's performance,with adjusted proportions substantially improving compressive strength and dynamic modulus.Firstly,three distinct proportioning options were developed for the recycled materials.Mix designs incorporating varying RAP/RAI ratios were used to determine the optimal mix parameters:moisture content,cement dosage,and emulsified asphalt content.Subsequently,comprehensive performance evaluations were conducted through high-temperature wheel tracking tests,freeze-thaw splitting tests,uniaxial compression tests,and dynamic modulus measurements to analyze the pavement characteristics of the three ECRM formulations.Experimental results demonstrate:Compared with ECRM with a blending ratio of RAP:RAI:new aggregate=30:50:20(Option 1),the dynamic stability,freeze-thaw splitting strength ratio,compressive strength,and compressive resilient modulus of ECRM under Option 3(RAP:RAI:new aggregate=50:30:20)decreased by 31.8%,5.2%,16.4%,and 13.1%,respectively.This indicates that increasing RAP content while reducing RAI proportion enhances the tensile strength of ECRM,yet adversely affects its high-temperature stability,moisture resistance,and compressive performance.This work not only addresses the challenge of jointly utilizing asphalt pavement waste and base waste,but also provides a cost-effective and sustainable method for the stable application of milling material resources in road engineering. 展开更多

Formulating oil-based drilling fluids(OBDFs)with an ultra-low oil-to-water ratio(OWR≤60:40)presents a formidable stability challenge due to the maximized interfacial area and intensified stress on the interfacial film under high-temperature,high-density conditions.To address this,we engineered a synergistic stabilization system through molecular and colloidal design.A novel hyperbranched polyamide emulsifier(epoxidized soybean oil polyamide)(ESOP),synthesized from epoxidized soybean oil,exhibits superior thermal stability and interfacial activity due to its hyperbranched architecture.Combined with calcium petroleum sulfonate(CPS)and hydrophobic nanosilica(HNs),it enables a high-performance OBDF with an ultra-low OWR of 60:40.The results show that the optimized formula achieves an excellent demulsification voltage of 1290 V,an ultra-low HTHP fluid loss of 1.5 mL,a yield point of 12.9 Pa,and a superior sag factor(SF)of 0.504,outperforming both base and commercial systems.Mechanistic studies reveal a multiscale stabilization strategy involving a dense composite interfacial film,Pickering stabilization,a 3D network,and a unique thermally triggered self-reinforcement effect.This work not only provides a cost-effective OBDF formulation but,more importantly,establishes a molecular topology engineering paradigm for stabilizing complex industrial fluids under extreme conditions. 展开更多

Waterborne acrylic coatings are widely utilized due to their cost-effectiveness,high transparency,strong resistance to weather and chemicals,impressive mechanical properties,and excellent adhesion to various substrates.In these coatings,a reactive emulsifier containing phosphate groups can be integrated into the molecular chain during polymerization,which enhances the coating's compactness and corrosion resistance.This work focuses on the synthesis of styrene-butyl acrylate(St-BA)latex and methyl methacrylate-butyl acrylate(MMA-BA)latex using the reactive phosphate emulsifier ANPEO10-P1through seed emulsion polymerization,achieving a conversion rate of approximately 99%and a solid content close to 50%.The resulting coatings from St-BA and MMA-BA latexes demonstrated long-term corrosion protection for carbon steel and aluminum alloy due to in-situ phosphatization,effectively preventing flash rust.Notably,the MMA-BA coating exhibited remarkable durability,enduring immersion for up to 1224 h(51 d)on Q 235 carbon steel before reaching the failure threshold(|Z|_(0.01 Hz)≤106Ω·cm2)on Q 235 carbon steel.On 5052 aluminum alloy,the St-BA coating maintained|Z|_(0.01 Hz)>108Ω·cm2for 480 h(20 d).Furthermore,the corrosion resistance of St-BA and MMA BA coatings on Q 235 steel sheet and 5052 aluminum alloy surpassed that of commercially available MMA-BA and St BA coatings after immersion in a 3.5 wt%NaCl aqueous solution.This work also delves into the anticorrosion mechanism of MMA-BA and St-BA coatings. 展开更多

Insulin entrapped nanocapsules to use polylactide （PLA） as the encapsulating material were prepared through a modified water-in-oil-in-water （W/O/W） emulsification and solvent evaporation method, The average particle size of PLA nanocapsules obtained was decreased to （181.5 ± 8.4） nm, and capably adjusted from 180 to 370 nm by using different types and content of nonionic emulsifiers. The influence of emulsifiers on property of nanocapsules was discussed in detail. The effects of spans and tweens to modify the size of the nanocapsules were different, which can be due to the distribution of the surfactants on the inner interface between the inner water and oil of the double emulsion. The encapsulation efficiency and drug release of nanocapsules were affected obviously by the content and type of emulsifiers. 展开更多

The Makran Sea is a complex marine environment.The purpose of this research is screening of emulsifier-producing bacteria in this marine environment and optimization of emulsifier production by the best-producing strain.Marine samples(seawater and sediments)were collected from four different zones in the Makran Sea.The emulsification activity index(E24)and Bacterial Ad-hesion To Hydrocarbons(BATH)were used to select the best emulsifier-producing strains.The prevalent strains were identified by PCR.The optimization of the emulsifier production medium by the best strain was done by two-level factorial design.Seventeen emulsifier-producing strains were isolated from sediments and seawater in the Makran Sea.The strains M6,BS-2,and J6 were select-ed between all isolates because they have 83%,91%,and 85%emulsification activity(E24)respectively.The results of sequencing confirmed that these three strains(M6,BS-2,and J6)belong to Cobetia marina,Shewanella alga,and Thalassospira permensis re-spectively.Maximum emulsifier production occurred at crude oil concentration(4%,v/v),peptone(2.5 g/L),yeast extract(1.5 g/L),molasses(2%),and at a temperature of 25℃.The results of this research confirmed that the Makran Sea has the potential to reach ro-bust marine bacteria with different biotechnological applications. 展开更多

In this paper,using a single-step method,resveratrol(RES)-loaded egg white protein(EWP)nanospheric particles were successfully prepared.The micelle behavior,micromorphology,molecular structure changes,and emulsifying properties of the nanoparticle were analyzed,and the molecular interaction between EWP and RES and the environmental response stability of the nanoparticle was characterized.The results show that I373/I385dropped from 1.1 to about 0.8,indicating that high concentration of ethanol induced EWP to form a more hydrophobic and less polar structure.RES promoted the uniformity of the nanoparticle and formed a tightly-packed spherical three-dimensional structure by characterizing microstructure.Raman and infrared spectroscopy revealed enhanced hydrogen bonding between EWP and RES,increased g-g-g and t-g-t disulfide bonds,and the formation of three-dimensional helical structures due to the opening of flexible structural intervals.Molecular docking analysis identified hydrogen bonds and hydrophobic interactions as the main forces facilitating the binding between RES and EWP.Particle size analysis showed that D3,2decreased from 30.51 to 17.88µm,indicating better emulsion stability.The preservation of RES at 0.4 mg/mL was 94.49%in 50 mM NaCl and 83.68%in 500 mM NaCl,with no significant stability change(p>0.05)over 48 h,revealing a concentration dependence of salt ions and storage stability of RES in the nanoparticle.This study establishes a foundation for exploring the incorporation of high-value hydrophobic compounds into EWP. 展开更多

Responsive nanocontainers have dual functions in targeted delivery of corrosion inhibitors and emulsion development of shale oil in oil and gas fields,exhibiting potential for simultaneously achieving metal protection and efficient oil and gas development from a material perspective.Here,we propose the preparation of a pH-responsive nanocontainer,HMSNs-g-PDEAEMA(poly[2-(N,N-diethyl amino)ethyl-methacrylate](PDEAEMA)grafted onto hollow mesoporous spherical silica(HMSNs)),to integrate the delivery of 2-mercaptobenzothiazole(MBT)for targeted corrosion inhibition and the emulsification of oil as Pickering emulsifiers.Under acidic conditions(reduced pH value caused by localized corrosion or high concentration acidic gases),PDEAEMA chains are protonated and extended by electrostatic repulsion,exposing pores on HMSNs surface and allowing the controlled release of loaded MBT molecules.Once transforming into a neutral or alkaline environment,the responsive release of the MBT process is inhibited.After the fluid passes through the wellbore and enters the shale layer,the HMSNs-g-PDEAEMA nanocontainers act as Pickering emulsifiers to achieve emulsification.The emulsified oil can be extracted onto the ground more efficiently,and a following pH-responsive demulsification process can be achieved.Overall,through a pH-responsive nanocontainer material,the dual function of corrosion inhibition and emulsification in oil and gas development is possible to be simultaneously achieved. 展开更多

The trends of consuming or using eco-friendly,biodegradable products due to the change in the lifestyle of the people have led to the exploration of new sources from plants or animals.Seed mucilage(SeM)is an underexplored component of plants that can be brought into play to deal with such problems.Mucilage,a viscous polysaccharide that can be obtained when seeds like chia,flax,garden cress,and tomato get hydrated and form a slimy,gel-like substance around the seed coat,can be utilized due to its unique characteristics.It has been used in developing many products such as bio-based films,plant-based dressing wounds with antibacterial effects,a medium for oral drug delivery,edible coatings,etc.Primarily composed of soluble fiber,it exhibits effects on human health,including blood glucose management,cholesterol,weight reduction,antioxidant(AOx),and antimicrobial activity.It offers a range of functional properties,including emulsification,stabilization,foam formation,fat replacement,encapsulating agent,flocculation,coagulation,and medium for drug release.These attributes make SeM a suitable component for applications in various sectors like food and pharmacy.Further study in this field may open more opportunities to address environmental problems and contribute to sustainability.This review explores aspects of SeM,emphasizing its functional properties and highlighting its current as well as potential applications across various sectors. 展开更多

As an emerging technology,electrospinning can effectively encapsulate active compounds for active packaging.Notably,stimulating the release of active ingredients by photostimulation is conducive to improving their bioavailability during food packaging and accurately playing the role of preservation.This study prepared an oregano essential oil emulsion using gelatin-gum arabic as a compound emulsifier with zinc oxide nanoparticles(ZnO NPs).The emulsion stability test identified 20%and 25%(w/v)gelatin-gum arabic solutions as optimal for electrospinning.On this basis,gelatin served as the film-forming substrate,incorporating the emulsion to produce composite fibrous membranes via electrospinning.The membranes were then exposed to ultraviolet C(UVC)radiation for 0 h and 4 h.Results revealed that UV irradiation activated ZnO NPs,generating reactive oxygen species that disrupted the emulsion interface and fiber structure,facilitating essential oil release.Additionally,UV treatment enhanced the membrane's antioxidant capacity,with DPPH radical scavenging showing sustained release over 4 d.Applied to chilled chicken breast packaging,the UV-stimulated membrane significantly reduced microbial counts by day 6 at 4℃,demonstrating the potential for chilled meat preservation.These findings offer insights for developing UV-stimulated active packaging systems. 展开更多

Urethane acrylate anionomer (APUA) as a kind of new type polymerizable emulsifier was synthesized using 2,4-toluene diisocyanate (TDI), polypropylene glycol (PPG), 2-hydroxyethyl methacrylate (HEMA) and dimethylolpropionic acid (DMPA). The critical micelle concentration (CMC) of APUA was measured by the methods of conductance and surface tension. The comparative studies between polymerizable emulsifier AUPA and conventional emulsifier sodium dodecyl sulfate (SDS) were carried out in the emulsion polymerization of methyl methacrylate (MMA). Polymerization kinetics, stability, size and morphology of the latex particles were investigated. It was found that in APUA both water soluble initiator potassium persulfate (KPS) and oil soluble initiator 2,2'-azobisisobutyronitrile (AlBN) can start the reaction of MMA, and the polymerization rate and yield were very high. On using AlBN as an initiator, the conversion-time behavior of MMA with APUA as emulsifier was different to that of SDS as emulsifier, signifying a different nucleation mechanism of the polymer latex particle. The average size of the two kinds of particles is about 50 nm. The particle size decreases with increasing emulsifier concentration. On using KPS as the initiator, APUA as emulsifier, cross-linking hydrogel of PMMA would be formed, but SDS was used as emulsifier and the hydrogel of PMMA was not present. 展开更多

Its nutritional significance,coupled with its role in cereal food processing, has prompted a surge of studies focusing on the valorization of wheat bran AX. Moreover, the hydrolyzed derivative, arabinoxylan oligosaccharides(AXOS), demonstrates prebiotic and antioxidant properties, offering potential avenues to mitigate the risk of chronic diseases. This review summarizes current knowledge on the valorization of wheat bran AX in terms of the processing and nutritional properties of AX. Moreover, multiple novel applications of AX in the materials area, including biodegradable food packaging films, delivery of bioactive substances as nanoparticles, and the manufacture of food emulsifiers, are also highlighted to extend the utilization of AX. This review underscores the immense potential of wheat bran AX, advocating for its exploitation not only as a nutritional asset but also as a primary ingredient in advanced materials. The synthesis of nutritional and materials perspectives accentuates the multifaceted utility of wheat bran AX, thereby paving the way for sustainable valorization pathways. By unraveling the latent potential within AX, this paper advocates for the holistic and sustainable utilization of wheat bran in diverse, value-added applications. 展开更多

Objective:To explore the effect of emulsified isoflurane(EI)on apoptosis of anoxia-reoxygenation neonatal rat cardiomyocytea and relevant protein expression.Methods:Cardiac muscle anoxiareoxygenation damage model was established with culture in vitro neonatal rat cardiomyocytes.The cardiomyocytes were divided into control group,model group,fat emulsion group and EI group.The cardiomyocytes apoptosis rates and lactic dehydrogenase(LDH),superoxide dismutase(SOD)and malondialdehyde(MDA)index standardization were detected after relevant treatment The expression of apoptosis-related proteins Bel-2,Bax and Caspase-3 were detected with Western blot approach.Results:After hypoxiaeoxygenation(H/R)model was treated by EI,the cells apoptosis rate decreased and was dramatically below the fat emulsion group(P<0.05),Cardiomyocytes biochemical index detection presented that,compared with the control group that the LDH activity and MDA content dramatically increased(P<0.05),while the SOD activity notably decreased(P<0.05);compared with the H/R group,the SOD activity of the fat emulsion group and EI group increased(P<0.05);while the LDH activity and MDA content decreased(P<0.05).And the change of the EI group was more remarkable than the fat emulsion group(P<0.05).The Western blot analysis presented that,compared with the control group,the Bcl-2 protein expression of the other groups significantly decreased(P<0.05),the expressions of Bax protein and Caspase-3protein increased significantly(P<0.05);compared with H/R group,cardiomyocytes Bc1-2protein expression of EI group increased significantly(P<0.05),the expressions of Bax protein and Caspase-3 protein decreased significantly(P<0.05),and the change of EI group was more remarkable than the fat emulsion group(P<0.05).Conclusions:EI can inhabit the apoptosis of anoxia-reoxygenation damage model cardiomyocytes,and may he related to the up-regulation of expression of Bcl-2 and down-regulation of expression of Caspase-3 protein. 展开更多
