Considering the development of CFRPs, addressing the challenge through the simplistic industrial operational methods to achieve high strength and toughness in carbon fiber-reinforced epoxy resin composites (CFRPs) is imperative. In this work, an innovative approach introduced to improve the strength and toughness of CFRPs by application of a nano emulsion encapsulated polyhedral oligomeric silsesquioxane (POSS) sizing agent (POE sizing agent). The employment of a POE sizing agent markedly enhanced the surface energy and roughness of carbon fibers (CF) as well as the interface properties of CFRPs. Furthermore, the 10-PCF/EP demonstrated superior strength and toughness. Relative to the CF/EP, their interlaminar shear strength, flexural strength, and unnotched impact strength increased by 24.9%, 37.8%, and 45.6%, respectively, reaching 99.8 ± 2.3 MPa, 1376.8 ± 21.6 MPa, and 94.9 ± 4.6 kJ/m2. Concurrently, the 10-PCF/EP laminates exhibited outstanding impact resistance, minimal damage area, and enhanced compressive strength after impact. Additionally, the strength, bundling, and flexibility of the sized CF were maintained, ensuring the processability of CF. The utilization of POE sizing agent for strength and toughness improvement in CFRPs offers a straightforward and industrially feasible approach. This research opens up a novel strategy for high-performance CF and CFRPs preparation. © 2024, The Authors. All rights reserved.

The design of novel active sites provides a promising route for the adsorption and removal of harmful molecules such as nitrogen oxides. The introduction of heteroatom with different electronegativity from those of carbon atoms into graphene skeleton could influence electronic configuration and thus endow graphene nanopores with improved properties for chemical separation, as well as molecular recognition and reduction. Here nanopores in graphene decorated by Si atoms are atomically-resolved using scanning transmission electron microscopy (STEM). Density functional theory (DFT) calculations indicates that such Si nanopores in graphene can chemisorb nitrogen oxides (NO, NO2) which then can be reduced via processes with rather low energy barriers. Intentional patterning Si nanopores in graphene may introduce new possibilities for metal-free, low cost, and high-performance catalysts for NOx reduction. © 2023, The Authors. All rights reserved.

Thermoelectric technology, which gains attention as a sustainable and eco-friendly energy source, has blocked application by low conversion efficiency. To address this, we utilized entropy engineering to create advanced Bi1-x-2yPbxCayYbyCuSeO (x = 0-0.08, y = 0-0.05) thermoelectric materials. Our method involved optimizing energy bands and tailoring all-scale hierarchical microstructures. By incorporating Yb, we reduced the gap between the light band and Fermi level, resulting in high mobility. Combined with a high carrier concentration, Bi0.85Pb0.05Ca0.05Yb0.05CuSeO achieved exceptional conductivity of 180 S/cm at 873 K, surpassing pristine BiCuSeO by 12 times. The addition of Pb flattened the energy band, enabling Bi0.88Pb0.06Ca0.03Yb0.03CuSeO to maintain a high Seebeck coefficient and achieve a power factor of ~700 μWm-1K-2. Furthermore, the inclusion of CaO2 impeded BiCuSeO growth and facilitated the formation of multiscale nanograin boundaries. This, combined with increased entropy causing significant lattice distortion, led to extremely low thermal conductivity in Bi0.88Pb0.06Ca0.03Yb0.03CuSeO sample (κlat ~0.244 Wm-1K-1 and κtot ~0.461 Wm-1K-1 at 873 K). Consequently, Bi0.88Pb0.06Ca0.03Yb0.03CuSeO achieved a remarkable ZT of 1.2, outperforming pristine BiCuSeO by a factor of 2.5. In addition, we evaluated the thermoelectric conversion performance of the BP6CY3/n-type PbTe multi-legged device, achieving a maximum efficiency of ~10% at ΔT = 561 K. © 2023, The Authors.
