Currently, more than 40% of reservoirs are located in deep layers. This scenario imposes significant technical challenges and requires the development of advanced technologies for the efficient and safe exploitation of these resources. This work deals with developing core–shell nanocomposites with silica nanoparticles as the core and the tetrapolymer as the shell and the preliminary evaluation of its applications as an additive in water-based drilling fluids under thermal aging conditions. The synthesis was carried out using two different methodologies, and the formation of the structures was confirmed by Fourier transform infrared spectroscopy/far infrared spectroscopy (FTIR/FIR) and energy-dispersive spectroscopy (EDS) analysis, which showed the presence of atoms of the polymer matrix and the characteristic bonds. Thermogravimetric analysis revealed that the structures showed good thermal stability with initial degradation temperatures above 260 °C. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) analysis indicated morphological changes and dynamic light scattering (DLS) analysis showed a particle size range around 500 nm, with a tendency to aggregation in aqueous media. The two nanocomposites showed excellent performance in preliminary tests, improving and stabilizing the rheological properties after the aging process. The success in obtaining these hybrid structures opens up new possibilities for the development of additives to improve the performance of drilling fluids in deep and ultra-deep well environments.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":645,"journal":{"name":"Journal of Materials Science","volume":"60 19","pages":"7859 - 7871"},"PeriodicalIF":3.5,"publicationDate":"2025-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144125775","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The properties of the nanofluid are strongly dependent on the characteristics of the nanoparticles dispersed in the base liquid. Furthermore, both the morphology and composition of the nanoparticles are significantly influenced by the method of their production. This study examines the effects of arc-discharge synthesis of carbon nanoparticles on their morphology and composition, as well as on the optical properties, viscosity, and thermal conductivity of the resulting nanofluids. Numerical modeling indicated that helium pressure in the reactor chamber influences the spatial distribution of gas temperature and carbon concentration in nanoparticle formation zones, making pressure a key factor in synthesis control. Experimental studies provided novel insights into how reactor pressure influences the morphology and composition of the nanoparticles. In turn, these synthesized carbon nanoparticles proved effective in nanofluids for direct absorption solar collectors. Comprehensive studies revealed that nanoparticle dispersibility in water and nanofluid stability rely heavily on the presence of C=O and C–O–H bonds on their surfaces. The research demonstrated that carbon nanoparticles maintain effective thermal conductivity and viscosity in nanofluids, which are crucial for solar collector applications. Additionally, optical studies indicated that the high specific surface area and conjugated graphitized structure of carbon nanoparticles enhance photothermal energy conversion, enabling more efficient solar collector designs with smaller geometric dimensions.</p></div>","PeriodicalId":645,"journal":{"name":"Journal of Materials Science","volume":"60 19","pages":"8057 - 8077"},"PeriodicalIF":3.5,"publicationDate":"2025-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144125776","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Compared with the pure MoS₂ material, adding Se source during the hydrothermal process allows the material to be in-situ doped with an equal amount of Se, resulting in the formation of ternary MoSSe. Furthermore, acid treatment of carbon nanotubes (CNTs) was introduced during the hydrothermal process to obtain MoSSe/CNTs composite materials. The MoSSe particles composed of numerous uniformly soft ultrathin nanosheets were scattered across the surface of acid-treated CNTs to form the 3D-network architecture MoSSe/CNTs. This structure would effectively prevent the lamellar reaggregation of the nanocluster, relieve structural variation during the storage process, and was beneficial for reduced Li⁺ diffusion barrier, thereby improving the electrochemical performance of lithium-ion batteries (LIBs).

The AC nanoparticles were dispersed in NR latex, forming a coating solution that modified the NR film surface. The effects of AC loading on the surface morphologies, TENG electrical output, dielectric properties and mechanical strength of the NR composites were investigated.

Additionally, the AC-NRF films demonstrated improved mechanical strength and durability, with tensile strength increasing proportionally to AC content. Due to the high surface area and porosity of AC nanoparticles, the composite films were further applied in environmental applications, exhibiting the ability to filter particulate matters (PMs) including PM_2.5 and PM₁₀, as well as to adsorb CO₂ gas.

In order to solve these problems, this paper introduced Ti(SO₄)₂, a chemically stable inorganic material and crucial industrial intermediate in TiO₂ synthesis, as an economically viable and easily accessible source.

Therefore, this study employed aberration-corrected transmission electron microscopy to characterize MPP-based carbon fiber samples and integrated computer vision technology to construct a realistic atomistic model incorporating a specific scaling factor. The effect of the scaling factor on model accuracy was systematically evaluated by comparing XRD and tensile simulation results with experimental data. Additionally, nanoindentation experiments revealed that elastic deformation predominates when the indenter compresses MPP-based carbon fibers longitudinally, whereas transverse indentation exhibits greater plastic deformation. Indentation simulations elucidated the underlying mechanism: Longitudinal compression primarily induces the bending of graphite sheets without covalent bond breakage, whereas transverse compression leads to more interlayer shearing due to the rupture of van der Waals bonds. Ultimately, the optimal scaling factor was determined to fall within the range of 8–12.

This study investigated the causes of these defects and proposed solutions to mitigate them. Thermal imaging and finite element method (FEM) simulations identified heat accumulation as the primary cause of shrinkage defects. To address this, we introduced forced convection, which reduced the temperature in the heat accumulation area by up to 550 °C and increased the heat transfer coefficient (HTC) to a maximum of 1930 W/m² K. Temperature-dependent HTC data were incorporated into the simulation software, and the results confirmed that forced convection effectively eliminated hot spots, which was subsequently validated experimentally. This solution also reduced the secondary dendrite arm spacing (SDAS) length from 57.77 ± 1.2 to 38.64 ± 0.82 μm, marking a 33% reduction, thereby enhancing the product’s mechanical properties. In actual production, forced convection reduced defects in the gating area to 0%, with the maximum defect length decreasing from 16.7 to 9.7 mm, demonstrating a significant improvement.

In this study, a novel polyurethane was synthesized through the combination of SO, diethanolamine (DEA), dicyclohexylmethane 4,4′-diisocyanate (HMDI), and bis(2-hydroxyethyl) disulfide (HEDS). The incorporation of HEDS as a cross-linking agent facilitated the formation of a cross-linked network structure during the chemical cross-linking pre-polymerization reaction of the polyurethane main chain. The resulting polyurethane adhesive demonstrated remarkable rebonding capability, maintaining good bond strength through up to nine rebonding cycles, and exhibited exceptional shear strength of 7 MPa. Furthermore, the adhesive-coated substrates maintained substantial shear strength after 24-h immersion in various pH solutions, indicating excellent chemical stability.
