Fourier-transform infrared (FTIR) analysis revealed that electro-UV aging caused up to 45% reduction in Si-CH₃ groups and 32% loss in Si–O-Si bonds for SR0 SR, while electro-thermal aging produced comparatively smaller reductions. Unlike prior studies that examined UV and thermal aging separately, this work combines electrical stress (electro-UV and electro-thermal) to test field aging conditions. SR0 exhibited significant degradation, with a 45% loss of Si-CH₃ groups and a 32% reduction in Si–O-Si bonds, shifting toward HC5-HC6 hydrophobicity classes. This was confirmed by largely unchanged FTIR spectra and consistent hydrophobicity within the HC1-HC2 range. Leakage current (LC) analysis under both AC and DC stress further supported this: SR0 exhibited a 24% rise in AC LC and 43% rise in DC LC, while the 5 wt.% filled sample limited increases to just 6% and 10%. Electro-UV aged samples exhibited higher peak leakage currents than electro-thermal aged samples. DC leakage currents showed particularly large relative increases over time, consistent with continuous wet conduction once hydrophobicity was lost, whereas AC currents were somewhat limited by periodic dry-band arcing. Incorporating nano-SiO₂ markedly suppressed leakage current, with the 5% filled composite showing the smallest rise in both AC and DC leakage, reflecting its superior maintenance of surface hydrophobicity and electrical integrity. These findings underscore that a moderate nano-SiO₂ loading can significantly enhance the resistance of SR to electrical, UV, and thermal aging stresses. The developed nano-SiO₂ filled HTV silicone rubber composites are reliable for outdoor high-voltage polymeric insulators in transmission lines, particularly in regions with high UV exposure like Pakistan, where they offer enhanced resistance to surface erosion, hydrophobicity loss, and leakage current under electro-UV stress.</p></div>","PeriodicalId":776,"journal":{"name":"Silicon","volume":"18 11","pages":"3639 - 3655"},"PeriodicalIF":4.1,"publicationDate":"2026-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148667030","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 present study focuses on the development and characterization of a novel bio-composite reinforced with surface-modified jute fiber and pectin biopolymer derived from apple pomace, aimed at enhancing mechanical, tribological, moisture resistance, and flammability properties. This work addresses a key research gap by investigating the effect of 30-day service temperature conditioned silane-treated bio-based composites, a topic with limited prior studies. Pectin was extracted from industrial apple pomace using citric acid-assisted hydrolysis and was further processed via acetone precipitation and oven drying. Both jute fiber and pectin particles were surface-modified using a 3-aminopropyltriethoxysilane (APTES) solution to improve interfacial bonding and reduce service temperature induced degradation. Composites were fabricated using the hand layup technique, followed by room-temperature curing and post-curing. Among the unaged specimens, those containing 3 vol.% pectin demonstrated the highest tensile (149 MPa) and flexural strength (162 MPa), while the composite with 5 vol.% pectin exhibited the lowest wear rate (0.018 mm³/Nm), water absorption (0.001%), and flame propagation speed (5.53 mm/min). After service temperature condition of 50 °C for 30 days, silane-modified composites showed only marginal reductions in performance. For instance, tensile strength in aged specimen V22 reduced from 112 to 104 MPa, while water absorption in V25 increased only slightly from 0.001% to 0.009%, and wear rate rose from 0.018 mm³/Nm to 0.020 mm³/Nm, confirming the protective effect of silane treatment. Further, the developed silane-modified jute/pectin biocomposites are suitable for lightweight semi-structural and tribological components used in automotive interior panels, door trims, under-hood secondary parts, consumer product housings, and building interior elements, where moderate load-bearing capacity, low wear, moisture resistance, and flame retardancy under prolonged service temperatures of around 50 °C are required. Additionally, the use of apple pomace–derived pectin enables sustainable materials for eco-friendly panels, packaging supports, and interior structural inserts by valorizing agro-industrial waste while maintaining durability during long-term thermal exposure.</p></div>","PeriodicalId":776,"journal":{"name":"Silicon","volume":"18 10","pages":"3553 - 3564"},"PeriodicalIF":4.1,"publicationDate":"2026-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148628680","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}

Sustainable reinforcement strategies can address these limitations while reducing environmental impact. In this study, seashell-derived silicon nanoparticles were extracted via a thermal–chemical route and incorporated into an AZ91 magnesium alloy matrix using stir casting. The composites were fabricated with reinforcement contents of 0.5–2.0 wt%, followed by hot compaction at 350 °C and 400 MPa to improve densification. Comprehensive mechanical, tribological, and corrosion tests, along with microstructural analyses (SEM, TEM, XRD, and EDS), were conducted to evaluate performance. The optimized S1.5 composite exhibited superior mechanical and functional properties, including a 20% increase in ultimate tensile strength (220 MPa), 15% rise in yield strength (156 MPa), and 18% improvement in hardness (83 HV) over the base alloy. The compressive strength improved by 19%, while the wear rate decreased by 35% and corrosion rate reduced by 43%. These enhancements are attributed to uniform Si dispersion, grain refinement, and the formation of stable MgO/Mg(OH)₂ protective films. The mechanical and corrosion performance of the developed composites are comparable to SiC- and Al₂O₃-reinforced Mg systems (UTS 230–240 MPa, hardness 88–90 HV) reported in literature, demonstrating 95% performance parity with synthetic counterparts. Importantly, this approach aligns with circular economy principles by upcycling seashell waste into high-value reinforcement, minimizing resource depletion and environmental burden.

In this investigation, Acrylonitrile Butadiene Styrene (ABS) was reinforced with varying volume fractions (1–5%) of alkali-silane treated biosilica particles derived from sugarcane bagasse to develop eco-friendly composites suitable for 3D printing applications. The samples were designated as F (100 vol. % ABS), F1 (99/1), F2 (97/3), and F3 (95/5) according to the ABS/biosilica ratio. Standard test specimens were fabricated using fused filament fabrication (FFF) and subsequently joined by Friction stir wielding (FSW) in accordance with ASTM guidelines. Their mechanical (tensile, flexural, impact and hardness), wear, and flammability behaviours were systematically investigated. Results revealed that the inclusion of treated biosilica significantly enhanced the mechanical and functional performance of ABS. The composite F2 (3 vol. %) exhibited the highest mechanical strength, with a tensile strength of 150 MPa, flexural strength of 138 MPa, and impact strength of 3.9 J, demonstrating a substantial improvement over the neat ABS (F) sample. The improvement is attributed to strong filler-matrix interfacial bonding achieved through silane modification and uniform particle dispersion during 3D printing. In contrast, the F3 composite displayed superior tribological behaviour, wear of 20.82 micron and a coefficient of friction (COF) of 0.31, indicating enhanced surface durability. Similarly, the flammability resistance also improved progressively with biosilica content, measuring lowest flame propagation speed is 5.9 mm/min. Scanning electron microscopic (SEM) analysis confirmed homogeneous filler distribution and reduced defects in the printed composites. Overall, the findings demonstrate the alkali-silane treated biosilica effectively enhances the mechanical strength, wear resistance, and flame retardancy of 3D printed ABS composites, making them promising candidates for functional for functional and structural applications in sustainable additive manufacturing.</p></div>","PeriodicalId":776,"journal":{"name":"Silicon","volume":"18 10","pages":"3521 - 3534"},"PeriodicalIF":4.1,"publicationDate":"2026-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148628676","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}

Impurities such as carbon, oxygen, and silicon carbide were analysed in the solidified mc-Si ingot and compared with those obtained from a conventional system utilising a silicon nitride-coated quartz (SiO₂) crucible. The simulation results revealed a noticeable reduction in the concentration of these impurities in the mc-Si ingot when grown using the silicon nitride-coated MgO crucible, attributed to the improved chemical stability and reduced reactivity of MgO at high temperatures. Additionally, the MgO crucible significantly altered the thermal field of the DS furnace.
