To clarify the underlying mechanisms under different chemical conditions, this study investigated emulsions formed between dehydrated crude oil and produced wastewater, salt solutions, alkali solutions, polymer solutions, surfactant systems, alkali–surfactant systems, and alcohol solutions. Confocal laser scanning microscopy, droplet size analysis, and rotational rheological measurements were used to systematically evaluate the effects of chemical type, concentration, water cut, and crude-oil SARA fractions on emulsion properties. The results show that water cut is the dominant factor controlling emulsion phase behavior, while chemical type further affects the phase inversion point and microstructural evolution. Resins and asphaltenes, as the main natural surface-active components, participate in interfacial-film formation and influence emulsion stability. Overall, salt systems more readily promote emulsion destabilization; alkali systems inhibit droplet coarsening to some extent; polymer systems show relatively limited effects; alkali–surfactant systems exhibit pronounced concentration dependence; and alcohol systems contribute to emulsion stability. The rheological results mainly reflect the bulk rheological behavior of emulsions, and all systems exhibit shear-thinning characteristics.

To facilitate purification, recombinant proteins are often expressed with various affinity tags, with the His-tag being the most common. Melanin has emerged as a promising biomaterial with different excellent physicochemical properties. In this study, we successfully developed and characterized a melanin/alginate-based material incorporating cobalt ions (Co-M/A) as an alternative stationary phase for His-tagged protein purification. Co-M/A beads exhibited defined morphology and structural stability, which were critical for reproducible protein binding. EDX, XRF, XRD, and XRF analyses confirmed the presence of cobalt species in Co-M/A particles, while FTIR spectra suggested evidence of Co²<sup>+</sup> coordination with carboxyl and hydroxyl groups in the M/A matrix. After loading the protein solution on the Co-M/A beads, the emergence of amide I and amide II peaks was observed, indicating the successful capture of His-tagged proteins through specific coordination between histidine residues and Co²<sup>+</sup> ions. Functionally, Co-M/A demonstrated high specificity toward His-tagged proteins of different sizes and structures, while showing negligible non-specific binding to non-tagged proteins. Impressively, the purity of eluted proteins exceeded 95.3% after a single purification step using Co-M/A beads. Importantly, the functional activities of purified proteins, including nanobodies (A8) and enzymatic proteins (Lc-BoNT/A), were well preserved as confirmed by SDS-PAGE analysis and Western blotting analyses, ensuring downstream applications. In conclusion, this study demonstrates the successful development of Co-M/A beads as a promising stationary phase for His-tagged protein purification with high efficiency.</p></div>","PeriodicalId":520,"journal":{"name":"Colloid and Polymer Science","volume":"304 9","pages":"2491 - 2503"},"PeriodicalIF":2.9,"publicationDate":"2026-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148807660","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Cu<sup>2+</sup> adsorption performance and mechanism of CTS-g-AAC were systematically investigated.

Thermodynamic results showed negative ΔG, positive ΔH (22.28 kJ·mol⁻¹) and positive ΔS, demonstrating that the adsorption process was spontaneous, endothermic and accompanied by increased system disorder.

This enables the design of soft actuators with multi-field coupled responses and complex motion patterns, overcoming the limitations of traditional homogeneous materials. This review focuses on the most recent research advances in stimuli-responsive soft actuators based on colloidal nanomaterials. Following a detailed introduction of colloids currently applied in actuation systems, five types of colloid-based soft actuators, including light-responsive, heat-responsive, magnetically responsive, electrically responsive, and solvent-responsive actuators, are systematically summarized, with a focus on their actuation mechanisms, fabrication methods, and corresponding actuation behaviors. Finally, several typical applications of these actuators, such as soft grippers, artificial muscles, and biomimetic robots, are highlighted to provide an intuitive perspective on their application areas.

To resolve this conflict between wear protection and surface damage, this paper systematically introduced ZrO₂ nanoparticles into ZrSiO₄-containing NAO composites and investigated their influence on tribological behavior and tribofilm evolution under varying sliding speeds and contact pressures. The results revealed an obvious dual mechanism between ZrSiO₄ microparticles and ZrO₂ nanoparticles. ZrSiO₄ microparticles support the external load and promote intense tribo-oxidation that forms a protective iron-oxide layer at elevated speeds, yet their aggressive plowing action continuously scores the steel surface. Conversely, ZrO₂ nanoparticles can effectively remove pre-existing oxide layers on the steel surface and promote tribo-sintering of wear debris into a compact, continuous tribofilm, that effectively passivates the counterface and suppresses scratching. However, this protective sintered tribofilm is repeatedly torn and dislodged by hard ZrSiO₄ particles, resulting in continuous tribofilm regeneration that significantly raises the specific wear rate of the composite and introduces pronounced friction instability during the running-in stage. The synergy between ZrSiO₄ and ZrO₂ thus dictates a fundamental trade-off: nanoparticle-enabled counterface protection is obtained at the expense of moderately sacrificed composite wear resistance. These findings clarify the micro-nano synergistic tribological mechanism and provide a mechanistic basis for designing next-generation brake materials that balance counterface friendliness with overall tribological performance.</p></div>","PeriodicalId":520,"journal":{"name":"Colloid and Polymer Science","volume":"304 9","pages":"2413 - 2424"},"PeriodicalIF":2.9,"publicationDate":"2026-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148807498","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Melt Flow Index (MFI) measurements suggest no major change in flow behavior under the tested conditions. Dynamic mechanical analysis (DMA) indicated an increase in glass transition temperature after recycling, consistent with reduced molecular mobility due to cross-linking. Mechanical testing demonstrated that after two recycling cycles, a moderate decrease in tensile modulus and impact strength occurs, although the overall changes remained moderate. Interestingly, the regranulated PEEK sample exhibited improved flexural stiffness, while maintaining good processability.
