The unique semi-coated structure is characterized by SEM, SDF, and TEM. Compared with raw quartz sand proppant, the water contact angle of the epoxy semi-coated quartz sand proppant can even reach 141.6°, which is due to the rough surface and hydrophobic coating induced by semi-coated epoxy and hydrophobic stearic acid-modified TiO₂. Meanwhile, the water contact angle could be adjusted by controlling the weight content of quartz sand. Moreover, the semi-coated proppant can maintain its hydrophobicity after treated by boiling water for 4 h, indicating improved thermal stability. The physical properties including bulk density (1.44 g/cm³), apparent density (1.40 g/cm³), acid solubility (3.43%), and breakage rate (1.26%) of the semi-coated proppant decorated with stearic acid functionalized TiO₂ nanoparticles are improved. The thermal stability, acid solubility, and flow conductivity are analyzed as well.

The hydrogen storage capacity and hydrogen diffusion ability determined by the metal loading amount and uniform dispersion on the surface of silicon-based nanosheets are very important. Here, a series of Pd-Sn/SNS composite materials with different structures and properties were synthesized, and X-ray diffraction (XRD), scanning electron microscope (SEM), transmission electron microscope (TEM), X-ray photoelectron spectroscopy (XPS), pressure–composition–temperature (PCT), and electrochemical workstations were used to investigate the structure, morphology, electronic structure, hydrogen adsorption and desorption capacity, hydrogen diffusion ability, and cycling stability. The research results indicate that the insertion of Sn broaden the internal space of the SNS layers and increase the active sites for metal Pd deposition, raising the amount of metal deposition while ensuring the uniform distribution of metal Pd particles. This result leads to the promotion of electron transfers from the deposited metal to the substrate. The local electric field effect is enhanced, and the Kubas effect is boosted, which all improve the material’s hydrogen storage capacity. The maximum adsorption capacity is 4.91 wt% achieved by 15 wt% deposition sample at 450 K, and the diffusion coefficients of hydrogen D_H is 6.25 × 10^–6 cm²/s. At the same time, the cyclic stability of the material is also improved. The result of density functional theory (DFT) calculation showed that the insertion of Sn can promote the interaction between Pd deposited on the surface and H. Among them, the electron transfer number of 15 wt% Pd-Sn/SNS is the largest of 3.79 e, and the binding energy of metal atom Pd and the substrate is the largest.

As environmental concerns continue to grow, there is an increasing focus on greener materials and manufacturing processes. The utilization of these environmentally friendly alternatives as substitutes for synthetic fiber filled polymer matrices in 3D/4D printing is driven by the objective of enhancing the material properties of printed items while reducing material costs. 3D/4D printing, also known as additive manufacturing, represents a promising frontier in environmentally friendly manufacturing.

Once the patch has penetrated the skin, the GA-loaded MNs (GA-MNs) are quickly separated from their base and enter the skin.

Compared with topical minoxidil, which requires daily treatment, animal studies have shown that GA-MNs can increase hair regeneration more effectively with lower dose frequency; the number of hair follicles in the GA-MNs group reached 83.68 ± 4.52%, which was significantly higher than that of the minoxidil group (56.93 ± 3.21%).

Research reveals that In doping lowers the solidus, liquidus, and peak temperatures, while increasing the melting range and undercooling. The matrix phases of 4In and 8In solders are β-Sn. When the In content exceeds 12 wt.%, the γ-InSn₄ phase starts to appear in the matrix, the matrix is transforming from the original single-phase into a dual-phase matrix. Consistent with it, the interfacial compound phase also has In doped, forming Cu₆(Sn, In)₅. During isothermal aging at 170 °C for 0–750 h, In doped less than 12 wt.% inhibits the growth of Cu₃(In,Sn) and Cu₆(Sn,In)₅, while the joints with just 12 wt.% In doping exhibit the strongest inhibition effect on the interface IMCs. After 750 h of aging, the 12In/Cu solder joint shows the best mechanical properties, with high shear strength and shear energy, minimal displacement damage, and consistent ductile fracture mode before and after aging. The nanoindentation results indicate that the hardness of the IMC layer remains nearly unchanged, and the modulus increases, along with an increase in E_i/H values and plasticity with increasing In content. These results are mainly due to the larger charge density difference between Cu and In atoms compared to those between Cu and Sn atoms, indicating a stronger Cu–In bond compared to the Cu–Sn bond. Because Young’s modulus is an intrinsic property, its magnitude may be related to the strength of bonding in the structure. This study, guided by CALPHAD for phase types and fractions, correlates nanoindentation with changes in mechanical properties and microstructure, and validates material performance through first-principles calculations. It has practical significance for controlling the growth of interface compounds, exploring the impact of the In element doping on solder joint performance, and stabilizing solder joint structures.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":7220,"journal":{"name":"Advanced Composites and Hybrid Materials","volume":"8 2","pages":""},"PeriodicalIF":23.2,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s42114-025-01236-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143496964","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
