The nanomotors are prepared through partially coating gold onto mesoporous silica nanoparticles and then immobilizing glucose oxidase (GOx) onto the gold patch.

The translation diffusion coefficient of the nanomotors is enhanced with increasing the glucose concentration. The translation diffusion coefficient reaches the maximum value at pH 5.5 when adjusting the pH of the glucose solution.

Pitifully, large amount of crude oil was leaked into the sea. Therefore, it is urgent to develop novel material with superior adsorption and recovery performance for the reutilization of the leaked crude oil. Herein, the modified sponge (CNTs/PDMS@SP) was constructed by using carbon nanotubes (CNTs) and polydimethylsiloxane (PDMS), and a facile one-step method. This sponge presented excellent hydrophobicity with the water contact angle of 142°, a high adsorption capacity for crude oil and several organic solvents, and an outstanding self-cleaning property. Moreover, the CNTs/PDMS@SP boasted excellent oil-water separation performance (up to 98 %). Even after 10 cycles, the separation efficiency still remained as high as 96.6 %. In addition, under illumination, the viscosity of crude oil was rapidly decreased due to the rapid temperature increment of CNTs/PDMS@SP by photothermal conversion, which endowed the modified sponge with the ability of fast adsorption of the crude oil. Under 1.0 kW/m², the surface temperature of the modified sponge reached to ca. 60 °C, and the adsorption amount of crude oil was as high as 13.12 g_{crude oil}/g_adsorbent. The surface temperature of CNTs/PDMS@SP consistently remained above 60 °C after several cycles under 1.0 kW/m², with intermittent light on and off, which proved its brilliant photothermal stability. Excitingly, even after 20 adsorption-extrusion cycles, the crude oil adsorption capacity of CNTs/PDMS@SP still reached to 8.73 g_{crude oil}/g_adsorbent, and the crude oil recovery rate was higher than 90 % under 1.0 kW/m². The superior performance of CNTs/PDMS@SP not only enables it as a promising adsorbent for the applications in crude oil leakage and oil-water separation, but also paves the way for the scale-up production of adsorbent with excellent recovery performance, fully reutilizing the crude oil and saving large amount of energy.</div></div>","PeriodicalId":278,"journal":{"name":"Colloids and Surfaces A: Physicochemical and Engineering Aspects","volume":"721 ","pages":"Article 137246"},"PeriodicalIF":4.9,"publicationDate":"2025-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144098553","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}

Molecular dynamics simulations showed that the OBS molecule adsorbs C₆F₁₂O through its fluorine-containing hydrophobic group, while its hydrophilic group interacts with the hydroxyl group of C₂H₅OH and adsorbs water molecules at the same time, resulting in the spontaneous formation of stable microemulsion systems. The fire suppression characteristics of this microemulsion on LIB fires are investigated using a self-built experimental platform. Experimental results show that perfluorohexanone O/W microemulsion can significantly reduce the flame temperature of LIB spraying by about 51 % in synergy with N₂, and at the same time, absorb the toxic and harmful gases through the release of the foam formed, and effectively reduce the concentration of CO by 43 % and the concentration of SO₂ by 65 %.
