This study explores the design of energy storage electrodes using 3D printing with a 316L stainless steel and polymer filament via fused deposition modeling. High-temperature sintering was used to debind the polymer and consolidate the stainless steel particles, with ceramic coatings (carbon and SiC) applied to prevent oxidation during heating. Electrodes sintered under carbon exhibited significantly higher specific capacitance (775 mF cm⁻² at 10 mV s⁻¹) compared to those sintered under SiC (&lt; 1 mF cm⁻²). Varying the infill ratio (40%, 70%, and 100%) revealed that a 70% infill provided optimal surface morphology and areal capacitance. This work is significant as it demonstrates a novel approach to utilizing 3D printing technology for the fabrication of customizable and efficient electrodes, addressing the critical need for energy storage 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 42","pages":"20558 - 20575"},"PeriodicalIF":3.9,"publicationDate":"2025-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145341153","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}

However, dielectric polymers appear to have low loss, fast charge and discharge speed, chemical stability, and good flexibility; therefore, they play a key role in power electronics and pulse power systems as a promising energy storage device. One effective way to address the shortcomings of pure polymers in electrical applications is by incorporating inorganic fillers into their matrix. Inorganic fillers can enhance properties such as dielectric constant, breakdown strength, and thermal conductivity, depending on their type and characteristics. Inorganic fillers can be categorized into four general groups. Incorporating each of these groups of fillers into polymer matrices can enhance certain key properties while simultaneously diminishing some desirable characteristics of the polymer. It is essential to have a comprehensive understanding of the fundamental principles and core concepts of dielectrics to effectively improve their attributes for the design and manufacture of devices. Considering this goal, we briefly reviewed the fundamentals of dielectric materials, the influence of the inorganic fillers on polymer properties, and recent advances in this field.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":645,"journal":{"name":"Journal of Materials Science","volume":"60 42","pages":"20160 - 20190"},"PeriodicalIF":3.9,"publicationDate":"2025-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145341141","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}

This study combines ab initio molecular dynamics (AIMD) simulations with experiments to systematically investigate the effects of aluminum content (Cr_0.5Al_0.5N and Cr_0.15Al_0.85N) and temperature (773 K, 973 K, and 1173 K) on the oxidation mechanism of the coatings. Simulation results indicate that Cr_0.5Al_0.5N preferentially form a dense (Cr, Al)₂O₃ mixed oxide layer at high temperatures, with Cr–O–Al bonding dominating during the initial oxidation stage, effectively inhibiting oxygen diffusion, while in Cr_0.15Al_0.85N, aluminum atoms selectively migrate to form discontinuous Al₂O₃ layers, resulting in only a small amount of (Cr, Al)₂O₃ mixed oxide layers, thereby reducing the protective efficacy against oxidation. By analyzing the average displacement of oxygen atoms bonded to metal atoms (Cr, Al), it is found that high temperatures (1173 K) significantly accelerate metal atom migration, promoting the densification of mixed oxides in Cr_0.5Al_0.5N. At the same time, CrAlN-1 (Cr_0.54Al_0.46N) and CrAlN-2 (Cr_0.17Al_0.83N) coatings were prepared. The results indicate that at 1173 K (900 °C), CrAlN-1 forms a denser oxide layer of 0.3 μm primarily consisting of (Cr, Al)₂O₃, whereas CrAlN-2 develops a thicker oxide layer of 0.45 μm dominated by Al₂O₃ with minor (Cr, Al)₂O₃ content. The XPS analysis confirmed that as the temperature increased, the CrAlN-1 coating formed more Cr–O–Al bonds with better oxidation resistance. The experimental results are consistent with the simulation calculations, verifying the feasibility of predicting the anti-oxidation performance of coatings using ab initio molecular dynamics methods, and providing a theoretical basis for the design of high-performance CrAlN coatings.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":645,"journal":{"name":"Journal of Materials Science","volume":"60 42","pages":"20406 - 20425"},"PeriodicalIF":3.9,"publicationDate":"2025-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145341133","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 resulting MPDMS@PNC composites are seen to retain near-unity quantum efficiency even after 24-h immersion in water and are observed to retain over 85% of the original efficiency even at 75 °C, displaying excellent thermal stability. More interestingly, by incorporating Au NPs and subjecting the material to mechanical pressure, the lifetime of the PNCs gets further increased. This is due to the more intimate spatial arrangement of Au NPs in the porous matrix, enhancing localized surface plasmon resonance (LSPR) coupling and thereby enhancing the photoluminescence (PL) of the PNCs.

An increase in bonding temperature or an extension of the holding time facilitated the formation of a high-quality metallurgical bonding interface.

When the temperature exceeded 500 ℃, creep contributed to over 70% of the deformation.

In this work, we address this limitation through a controlled doping strategy using antimony (Sb) and selenium (Se) to introduce targeted defects and microstructural modifications within single-crystalline Bi₂Te₃. Sb and Se substitutions create atomic scale strain, point defects, and micro-grain structures, enhancing phonon scattering without significantly disrupting the crystalline order. The resulting defect-engineered single crystals exhibit improved thermoelectric performance, with a notable reduction in lattice thermal conductivity and retention of excellent electrical properties. The co-doped compositions, Bi₂Te_2.7Se_0.3 and (Bi0.98Sb_0.02)₂Te_2.7Se_0.3, exhibited significantly enhanced thermoelectric performance, with Seebeck coefficients reaching ~ 253 μV/K and − 211 μV/K, respectively, over the 10–400 K range.

Further, a flexible thermoelectric device fabricated from these optimized materials generated output power of 2.7 nW and 3.35 nW at ambient temperature. The non-monotonic variation of the Seebeck coefficient with Sb content, showing an optimal enhancement at x = 0.04, highlights the delicate balance between carrier concentration and band structure modification, emphasizing moderate Sb substitution achieves the most favorable conditions for thermoelectric performance.
