However, precise regulation of the microcrystalline structure and pore configuration remains a critical challenge for achieving fast potassium-ion transport. Herein, an aromatic ring axial extension of HCPs monomer regulation strategy is proposed to construct the HCPs structure by employing aromatic monomers with progressively extended conjugated planes, including benzene, naphthalene, and anthracene. After pyrolysis, a series of PCs with systematically evolved microcrystalline and pore structures are obtained. The results revealed that increasing the planar aromatic ring number promotes the formation of ordered graphitic domains and induces a transformation of pore architecture from open pores to closed pore frameworks. In particular, anthracene-based HCPs derived porous carbon (PC) exhibits an interwoven long-range ordered microcrystalline structure and the highest closed pore volume (0.062 cm³ g⁻¹), which is attributed to the enhanced graphitization of PCs effect of extended polycyclic aromatic hydrocarbon units. As a result, A-PC exhibit superior reversible capacity (214 mAh g⁻¹ after 200 cycles) at a current density of 0.05 A g⁻¹ and outstanding rate performance (0.05-5 A g⁻¹). Kinetic analysis and <em>in-situ</em> XRD measurements reveal a sequential potassium-ion storage mechanism. Furthermore, a potassium-ion hybrid capacitor (PIHC) constructed with optimized A-PC anode delivers a high energy density of 126 Wh kg⁻¹ at power density of 338 W kg⁻¹ and maintains stable for over 4000 cycles at 1 A g⁻¹. This research offers new insights into the molecular design strategies for regulating carbon microcrystalline evolution and pore structure as well as promotes the advancement of high rate potassium-ion storage in PC materials.</div></div>","PeriodicalId":262,"journal":{"name":"Carbon","volume":"257 ","pages":"Article 121771"},"PeriodicalIF":12.7,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148566189","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the design and control of microscale structure in bitumen through nanotechnology is an intricate process and remains a challenge. This study reports a bitumen nanocomposite designed with micro-nano interfacial structure that exhibits 1-2 orders of magnitude improvement in both strength and toughness compared to base bitumen. The designed micro-nano interfacial structure uses spherical particles of styrene-butadiene-styrene copolymer (SBS) as an elastic substrate on which to efficiently assemble carbon nanotubes (CNTs) on a macroscopic scale to form inter<strong>-</strong>laminar CNT arrays; the inter-laminar CNT arrays are adsorbed on or physically associated with the SBS particles and act like hook-and-loop fasteners to fasten adjacent SBS particles together. This structural reinforcement enables more effective synergistic interfacial interactions between the CNTs and SBS, thereby enhancing intermolecular forces with specific bitumen constituents, particularly through strong bonding with the aromatic-rich asphaltene and resin fractions. Life cycle cost analysis results indicate that under the given assumptions, the higher initial material cost of the B/SBS/CNT nanocomposite is offset by the lower discounted renewal cost, thus achieving better overall economy. Our findings reveal the potential of nanotechnology to enhance the durability and life-cycle cost-effectiveness of infrastructure materials, thereby supporting the development of more resilient and economically sustainable engineering solutions.</div></div>","PeriodicalId":262,"journal":{"name":"Carbon","volume":"257 ","pages":"Article 121758"},"PeriodicalIF":12.7,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148566190","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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, carbon nanotubes@titanium (CNTs@Ti) hybrid-reinforced aluminum matrix composites were fabricated by spark plasma sintering (SPS). The influences of sintering temperature (500 °C, 560 °C, and 600 °C) on the microstructure and mechanical properties of the composites were systematically investigated, and the regulation mechanism of the Ti–Al interface modified by CNTs on the synergistic improvement of strength and ductility was emphatically revealed. The results show that the optimal sintering temperature of 560 °C achieved an optimized interface structure, and the composite exhibited excellent synergy of strength and ductility. A continuous non-brittle gradient interface of finely dispersed TiAl₃ and TiC phases and structurally intact CNTs is formed by precise control of atomic diffusion. The interface promotes the cross-interface dislocation transmission through controllable dislocation pinning, realizing strain coordination and stress self-relaxation effects, thereby activating the plastic deformation of Ti particles and achieving duplex-phase synergistic load bearing. When the sintering temperature rises to 600 °C, the TiAl₃ phase coarsens abnormally and induces severe dislocation tangling. CNTs react with Al to form brittle rod-like Al₄C₃, resulting in the simultaneous degradation of both strength and ductility. This study provides theoretical and experimental support for the interfacial design and strength-ductility synergy of high-performance hybrid-reinforced aluminum matrix composites.</div></div>","PeriodicalId":262,"journal":{"name":"Carbon","volume":"257 ","pages":"Article 121772"},"PeriodicalIF":12.7,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148566198","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, their inherently low electrical conductivity and single loss mechanism significantly restrict their absorption performance. Herein, Fe₃Si/SiC composite nanofibers were synthesized via electrospinning followed by high-temperature pyrolysis. Subsequently, a hierarchically porous SiC/Fe₃Si@rGO composite aerogel with multicomponent synergy is then constructed by combining ice templating with graphene oxide incorporation. The resulting aerogel achieved a minimum reflection loss (RL_min) of −46.68 dB at 8.84 GHz with a thickness of 3.0 mm. Moreover, within a thickness range of 1.5–5.0 mm, the material maintains RL &lt; −10 dB across the entire 4–18 GHz frequency range. Mechanism analysis reveals that the introduced Fe₃Si phase contributes magnetic loss, while the graphene sheets form a three-dimensional conductive network, enhancing both conductive loss and interfacial polarization. Additionally, the incorporation of graphene refines and enriches the pore structure, which optimizes impedance matching and promotes multiple scattering of EMWs. This work provides a viable strategy for the design of lightweight and high-performance EMW-absorbing materials.</div></div>","PeriodicalId":262,"journal":{"name":"Carbon","volume":"257 ","pages":"Article 121765"},"PeriodicalIF":12.7,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148342729","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
