However, knowledge about the characteristics of the STA vesicle-systems thus obtained is still limited. In the current work, the vesicles formed by simple STAs, alkyl trimethylammonium bromides (CnTABs), including dodecyl, tetradecyl, and cetyl ones (DTAB, TTAB, and CTAB), via a DHRH process were chosen. The aggregation numbers of the STA vesicles (Nv) were first estimated, and their fluorescence quenching kinetics was then investigated using the time-resolved fluorescence quenching (TRFQ) technique, which were compared with those of conventional vesicle systems. In particular, the mole fractions of CnTAB existing in the form of micelles (fm) in the vesicle systems were estimated using the TRFQ data. The Nv values of DTAB, TTAB, and CTAB were found to be ca. 7.33 × 104, 8.33 × 104, and 10.6 × 104, respectively, which are similar to those of conventional vesicles. In addition, the values of fluorescence quenching kinetic parameters obtained for the STA vesicle-systems are also similar to those of conventional vesicles. For the STA vesicle systems, vesicles coexist with micelles, but the fm significantly decreases with an increase in chain length. DTAB molecules exist mainly in the form of micelles (with fm ∼ 0.82), while TTAB and CTAB exist mainly in the form of vesicles (with fm ∼ 10-5). Overall, the properties of STA vesicles are similar to those of conventional vesicles. This work deepens our understanding on the features of simple STA-based vesicles.","PeriodicalId":103,"journal":{"name":"Soft Matter","volume":" ","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145205032","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite the prevalence of multiaxial stress states in design, the characterization of multiaxial behavior in soft polymers and gels has lagged behind that for stiff materials where standards have been developed to perform such measurements. Given the lack of standardization, determining an appropriate geometry and method to probe the multiaxial mechanical response of soft materials falls under the purview of the individual researcher. Herein cruciform samples capable of quantifying the failure behavior of soft polymers under biaxial tension are designed. Using digital image correlation to quantify the local deformations, it is found that controlling the relative compliances of the legs to the center square is key to observing multiaxial failure. Further, controlling the transverse stiffness of the legs is found to significantly impact the uniformity of the deformation state that develops in the center square. Finally, the failure stresses measured in cruciform samples with varied corner geometry are found to be in reasonable agreement with independent measurements of the failure stress from uniaxial extension and equibiaxial inflation. These findings have strong implications for the design of structures where multiaxial stress states develop during regular use.","PeriodicalId":103,"journal":{"name":"Soft Matter","volume":" ","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145197583","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our hybrid particle-continuum approach provides a promising solution by integrating multiple resolutions to overcome the limitations of traditional fracture theories and experimental methods. We model the crack tip by particles using coarse-grained molecular dynamics simulation and treat the rest as a continuum, enabling accurate representation of polymer behavior and realistic boundary conditions similar to laboratory fracture tests. Two distinct loading conditions, plane stress and plane strain, are applied to a center-cracked specimen. Our results demonstrate unique crack growth patterns: under plane stress, we observe crack tip blunting accompanied by a high plastic deformation zone. Under plane strain, cleavage occurs alongside crazing. Furthermore, we identify the specific stress states that initiate and drive crack growth and shape at the particle level for each loading scenario.","PeriodicalId":103,"journal":{"name":"Soft Matter","volume":" ","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145197634","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, evidence on their formation and their precise role in lowering the surface stress remains limited. In the present study, we combine neutron reflectometry using a Quadrotrough interfacial dilatational rheometer, with cryo-TEM imaging to investigate the conditions required for multilayer formation and their subsequent influence on interfacial properties. By comparing three model lipid systems with varying concentrations of hydrophobic surfactant proteins SP-B and SP-C, we demonstrate that a higher protein content is necessary for the formation of multilayers and the efficient re-spreading of lipids upon expansion. When comparing the model systems with the natural surfactant replacement Infasurf, we found that multilayers alone are insufficient to reduce the surface stress effectively.

Building on recent advances in interfacial self-assembly of fatty acid bilayers, we present here a robust and tunable strategy for stabilizing polyethylene glycol/dextran aqueous two-phase system emulsions using lyotropic lamellar phases doped with phase-separating polymers. We show that these lamellar phases spontaneously adsorb at the droplet interface, forming a stabilizing interfacial coating. By comparing multiple formulation routes, including lamellar phase pre-assembly with or without excess solvent and the previously used \"one-pot\" method, we demonstrate that all approaches yield equivalent droplet stabilization. Systematic variation of the lamellar phase concentration reveals a critical threshold necessary for emulsion stability. Beyond this threshold, excess lamellar material is dispersed into the continuous phase. A simple geometric model supports the hypothesis that this critical concentration corresponds to the amount required to fully coat the droplet interfaces. This strategy offers a straightforward yet precise formulation route that leverages the self-assembly and dilution behavior of lamellar phases, opening new avenues for designing fully aqueous emulsions stabilized without solid particles or synthetic surfactants.","PeriodicalId":103,"journal":{"name":"Soft Matter","volume":" ","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145197595","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Other factors, such as viscous stress and Marangoni stress, will also have major impacts on droplet stability. In this paper, systematic droplet coalescence experiments will be presented using a microfluidic Stokes trap geometry, as a function of viscosity ratio between droplet and continuous phase as well as surfactant concentration. The results show that more coalescence can be observed for systems with a lower viscosity ratio (smaller than 1), while few coalescences are observed for a higher viscosity ratio (larger than 1), as expected. More surprisingly, a non-monotonic trend of film drainage time as a function of surfactant concentration is observed for both Triton X100 and Glucopon 225DK. The film drainage time first increases and then decreases followed by plateaus with the increase of surfactant concentration, until a critical concentration value is reached. To better understand the non-monotonic relationship between film drainage times and surfactant concentration, two Marangoni numbers defined based on (1) the ratio of Marangoni time scale with surfactant diffusion timescale, and (2) the ratio of Marangoni stress with interfacial tension, are examined. The results from both Marangoni scaling agree with the experimental observations.","PeriodicalId":103,"journal":{"name":"Soft Matter","volume":" ","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145197706","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The actin cytoskeleton, which forms the mechanical structure of cells, consists of actin filaments that are assembled into networks and bundles by protein cross-linkers. Specific network and bundle microstructures are determined by the type of cross-linker and support different physiological functions. Recently, there is also evidence that protein condensates can nucleate bundle formation with cytoskeletal filaments. Here, we find that protein condensates interact with pre-polymerized actin filaments to form networks of bundles. The condensates absorb on actin bundles and relax into barrel shaped droplets, evocative of drops of simple liquids on fibers. We investigate the condensate spreading and measure contact angle that condensates make with bundles. Intriguingly, condensates at the intersection of bundles cause capillary bridges which induce network remodeling. Our results suggest that network formation, bundling, and remodeling in biopolymer assemblies could be induced by capillary interactions due to condensates.","PeriodicalId":103,"journal":{"name":"Soft Matter","volume":" ","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145184258","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To elucidate how the traveling wave of the ERK kinase signal directs collective migration, we constructed the mechanical model of the epithelial cell monolayer by considering the signal-dependent coordination of contractile stress and cellular orientation. The proposed model was studied by using an optogenetically controlled cell system where we found that local signal activation induces changes in cell density and orientation with the direction of propagation.

Therefore, interactions and colloids must be carefully chosen to ensure selectivity to guide the assembly, reversibility to enable large-scale reorganization and flexibility to finely tune colloid positioning. In pursuit of this, we study simple anisotropic colloids in the shape of half-disks fabricated using two-photon lithography and drive their self-assembly through their vertical faces using depletion interactions. Depletion interactions are widely used in the literature to induce colloidal self-assembly and can provide reversible interactions at low depletant concentrations. The specificity is a consequence of the geometry of the colloids, where the attraction between flat faces is favored by depletion interactions. We demonstrate that these interactions are transient, with survival times that depend on the shape of the interacting faces. The bond lifetime as a function of the depletant concentration is correctly predicted by a theoretical model based on the excluded volume. We also show that the flat surfaces can slide relative to each other offering flexibility to the bonds. We quantify this sliding and show that it follows a Boltzmann distribution governed by the depletion energy. Bond breaking between surfaces occurred predominantly when they are offset relative to each other. Incorporating this flexibility on bond lifetime in our model yields better quantitative agreement on the bond lifetimes. This quantification of specific, transient, and flexible bonds between simple anisotropic colloids could pave the way for the self-assembly of larger, defect-free colloidal structures.","PeriodicalId":103,"journal":{"name":"Soft Matter","volume":" ","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145147076","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
