In this study, we employed oligomeric bismaleimide (BMI), multifunctional epoxy resin (EP), and 4.4’-daminodiphenylmethane (DDM) as the resin matrix to prepare a new BMI/EP/DDM (BED) ternary resin molding compound aiming for high-temperature electronic packaging. With 2-ethyl-4-methylimidazole as the curing accelerator, the reactions including the addition of BMI with DDM, addition of EP with DDM, self-polymerization of EP, and self-polymerization of BMI facilely occurred during the curing process of BED system, making the molding process of BED be compatible with that of commercial epoxy molding compounds (EMC). With increasing the BMI content, the thermal stability of the cured BED resins was improved, showing the initial thermal decomposition temperature and char yield at 800 °C up to 388 °C and 55.7%, respectively. Compared with EMC, the BED molding compounds exhibited a glass transition temperature over 360 °C and a remarkable dimensional stability in the glassy state after curing, due to the enhancement of network chain rigidity by the introduction of BMI component. Although the cured BED was less ductile than the cured EMC at room temperature, showing lower flexural strength and higher flexural modulus, it had much superior flexural performance to the cured EMC at 250 °C. Therefore, BED was demonstrated to be a promising candidate for high-temperature electronic packaging applications.</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 4","pages":"2151 - 2164"},"PeriodicalIF":3.5,"publicationDate":"2025-01-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142994626","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}

In this work, we develop a novel flower-like gap-enhanced Raman tags (for brief, PMF-GERTs) wrapped with polydopamine (PDA)-functionalized molybdenum disulfide (MoS₂) nanosheets. In PMF-GERTs, 4,4′-biphenyldithiol (BPDT) Raman reporter molecules are embedded in the nanogap between the gold core and the flower-like shell, and PDA-functionalized MoS₂ nanosheets (PDA/MoS₂) were wrapped on the surface of the flower-shaped shell. Photothermal and photodynamic experiments show that PDA/MoS₂ nanosheets significantly improve the photothermal performance and photodynamic response ability of Raman tags in the NIR-II region. Under the irradiation of 1064 nm laser (1 W/cm²), the PMF-GERTs solution can heat up to 66 °C within 300 s, and the photothermal conversion efficiency reaches 43.6%. Moreover, PMF-GERT also has excellent photothermal stability and photodynamic properties and can perform effective phototherapy on 4T1 tumor cells. In Raman spectra and mapping imaging experiments, PMF-GERTs have strong enhanced Raman signals, lower detection thresholds and long-time physiological environment stability (72 h). In addition, PMF-GETRs also have excellent performance in simulating biological tissues and biological Raman mapping imaging. This novel Raman tag is expected to be used to develop phototheranostic nanoplatform that integrates Raman imaging diagnosis and photothermal and photodynamic therapy.</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 4","pages":"1873 - 1890"},"PeriodicalIF":3.5,"publicationDate":"2025-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142994354","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 effect of Zr on creep deformation behaviors was studied by OM, SEM, EBSD and AC-STEM. The results show that the addition of appropriate Zr (0.1 wt.%) inhibits crack initiation and premature cracking, prolongates the creep rupture time, reduces the minimum creep rate, and increases the proportion of steady-state creep duration. However, excessive Zr content (0.5 wt.%) can promote the continuous precipitation of μ, σ, and Ni₇Zr₂ phases at the grain boundaries, which is easy to become a crack source and reduce the creep performance. In general, the alloy with 0.1Zr addition has high creep strength, low tendency of intergranular cracking at high temperature, and the best overall creep performance.

Herein, a nanocomposite hydrogel composed of CuO nanoparticles (NPs) embedded in chitosan-formaldehyde (CsF) Schiff base hydrogel was explored as a catalyst towards the reduction of environmental pollutants. Green synthesis of CuO NPs was accomplished from watermelon rind extract. Spherical CuO NPs having an average particle size of 29.8 nm with a zeta potential of − 23.1 mV was obtained. The CuO NPs-integrated CsF hydrogel demonstrated good catalytic reduction of pollutants like 4-nitrophenol (4-NP), K₃[Fe(CN)₆], rhodamine B (RhB) and methyl orange (MO) in the presence of NaBH₄. The influence of different parameters on the catalytic activity and the kinetics was assessed. The apparent rate constant for reduction reaction of 4-NP, K₃[Fe(CN)₆], RhB and MO by the hydrogel was estimated to be 0.025 s^–1, 0.016 s^–1, 0.135 s^–1 and 0.099 s^–1 respectively.

In this study, phosphorus building gypsum, cement, and lime were used as the main materials, and water reducer and retarder were used as additives to prepare phosphorus gypsum cementitious materials under low water–cement ratio. Concurrently, the mechanical properties and hydration mechanism of phosphogypsum cementitious materials were investigated during both hydration and soaking processes, alongside a discussion on optimization strategies for enhancing their water resistance. The findings indicate that under low water–cement ratio conditions, rapid hydration of a substantial amount of phosphorus building gypsum occurs, leading to the formation of a spatial skeleton and significant enhancement in compressive strength. Some segments of the phosphorus building gypsum hydration process experience delay or cessation, while certain constituents of cement are densely packed, forming a compact system. Submerging in clear water gradually provides an adequate water environment, allowing for complete hydration of both phosphorus building gypsum and cement components, effectively filling the pores. Water immersion results in a material loss in the phosphogypsum cementitious system, leaving the pores formed after dissolution incompletely filled. In low water–cement ratio phosphogypsum cementitious systems, the secondary hydration process avoids exposure to a flowing solution environment, thereby circumventing material loss and achieving a complete and dense phosphogypsum cementitious system.</p></div>","PeriodicalId":645,"journal":{"name":"Journal of Materials Science","volume":"60 4","pages":"1853 - 1872"},"PeriodicalIF":3.5,"publicationDate":"2025-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142994690","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}
