Pin-on-disk tribology tests and molecular dynamics (MD) simulations under humid environment were conducted. It was discovered that the GO-MoS₂ hybrid nanofluid, at the optimal concentration combination (0.3 wt% GO + 0.1 wt% MoS₂), demonstrated a notably enhanced synergistic lubrication effect, resulting in a reduction of approximately 14.6 % in the average friction coefficient and 14.4 % in the wear rate when compared to the single nanofluid. Through interfacial tribochemical analysis, a protective polycrystalline tribofilm in the thickness of about 18.6 nm was formed on metal surface, consisting of ultra-fine GO, MoS₂ crystals and amorphous substances derived from the organic matters of nanofluids. Besides, from humid-environmental MD simulation results, there were lower friction force, normal force and peak temperature values in MD model containing both GO and MoS₂ nanosheets, meanwhile the lattice mismatch between different nanosheets led to high interlamellar repulsion, further mitigating the pressure and friction. By analyzing the absorption behavior of dispersant molecules, sodium dodecylbenzene sulfonate and triethanolamine molecules partially transferred from nanosheets to Fe surface. Based on the experiment and humid-environmental MD simulation results, the excellent tribological behavior of nanofluid was attributed to the polishing, mending, interlayer sliding effect of nanoparticles and the tribofilm induced by interfacial tribochemistry.</div></div>","PeriodicalId":278,"journal":{"name":"Colloids and Surfaces A: Physicochemical and Engineering Aspects","volume":"707 ","pages":"Article 135900"},"PeriodicalIF":4.9,"publicationDate":"2024-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143098953","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effects of metal ions on the interaction between SA and kaolinite were analyzed by zeta potential, fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS), and density functional theory (DFT). The results showed that Na⁺ and Mg²⁺ resulted in a decreasing of the viscosity and modulus of SA solution for they have the electrostatic shielding effect on SA. Ca²⁺ and Al³⁺ significantly increased the viscosity and modulus of SA solution because Ca²⁺ and Al³⁺ not only have the electrostatic shielding effect on SA but also could form the different network structure complexes. The order of the responsiveness of metal ions and SA sorted by intensity level was: Al³⁺&gt; Ca²⁺&gt;Mg²⁺&gt; Na⁺. SA has a dispersion effect on kaolinite particles under the background of Na⁺ and Mg²⁺, and SA has a flocculation effect on kaolinite particles in the presence of Ca²⁺ and Al³⁺. The flocculation efficiency of SA on kaolinite suspension containing Al³⁺ was much higher than that of SA on kaolinite suspension in the presence of Ca²⁺. Zeta potential and FTIR results showed that SA could be adsorbed on the kaolinite surface through electrostatic force and hydrogen bond in the presence of Na⁺ and Mg²⁺. Microscope observation^, XPS and DFT results showed SA could not only form chemical adsorption with Ca²⁺/Al³⁺ on the kaolinite surface but also be cross-linked with Ca²⁺/Al³⁺ to form a network structure, which could sweep and trap kaolinite particles in suspension.

EC, known for its biocompatibility and biodegradability, was used as the wall material in an oil phase separation method, with dichloromethane serving as low boiling point solvent. The microencapsulated alkaline protease (Mic-AP) was characterized using scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR) and thermogravimetric analysis (TGA). The enzyme activity was evaluated using casein as the substrate. It was found that optimal conditions for Mic-AP preparation were <em>m</em>_core:<em>m</em>_wall of 1:1, emulsifier of 5 <em>wt</em>%, and volatilization temperature of 40 °C, yielding up to 90 % microencapsulation efficiency, the enzyme activity up to 17,000 U/g. Microencapsulation of alkaline protease not only enhances its stability but also preserves its natural properties. It is proved that Mic-AP exhibits improved temperature resistance. Furthermore, the enzyme activity of Mic-AP is higher than that of AP at high temperature of 60 °C, 80 °C, 100 °C and 120 °C.

Kidney failure leads to the dramatic retention of small molecules (i.e., uremic toxins) within the blood compartment, and their effect on the inhibition of protein adsorption to PEO films is unknown. To understand the effect these uremic toxins have on protein adsorption, surfaces with different chain densities of end-tethered hydroxy-PEO were incubated in platelet-poor plasma laden with uremic toxins. PEO films were characterized using dynamic contact angles and X-ray photoelectron spectroscopy. PEO chain densities were verified using spectroscopic ellipsometry. Eluted proteins were characterized using immunoblot techniques. It was observed that PEO chain density and uremic toxins affected the amount of individually adsorbed proteins and the relative composition of the adsorbed protein corona; especially albumin, complement C3, factor XI, and fibrinogen.

Specifically, the n-n heterojunction designated as MT-3 achieved a RhB removal rate of 94.45 % within a 3-hour period, which corresponds to a 5.4-fold and 2.2-fold enhancement over the degradation rates observed for {001}TiO₂ and NH₂-MIL-101(Fe), respectively.
