“…However, pathological conditions induced by environmental influences, stress, and aging can lead to ROS regulation failure, resulting in oxidative damage to cellular macromolecules [3,4]. This oxidative damage accelerates age-related diseases such as cancer, inflammation, and cardiovascular diseases [5,6]. Therefore, studies on antioxidants that can effectively scavenge ROS are being conducted, with a focus on antioxidants obtained from natural products such as vitamins, carotenoids, and polysaccharides [3,7,8].…”

Undaria pinnatifida, a marine biological resource from which antioxidants such as polysaccharides can be obtained, is primarily distributed in the coastal areas of East Asia. Reactive oxygen species (ROS) are essential for physiological processes; however, excess ROS levels in the body result in cellular oxidative damage. Several extraction methods exist; however, factors such as long extraction times and high temperatures degrade polysaccharides. Therefore, this study aimed to increase the yield of U. pinnatifida sporophyll extract (UPE), a U. pinnatifida byproduct, using ultrasonication, an environmentally friendly extraction method, and identify UPE components with antioxidant activity. UPE_2, 4, 6, and 8 extracts were obtained at extraction times of 2, 4, 6, and 8 h, respectively. UPE_8 had the highest yield (31.91%) and polysaccharide (69.22%), polyphenol, (8.59 GAE μg/mg), and fucoxanthin contents (2.3 μg/g). UPE_8 showed the greatest protective and inhibitory effects on ROS generation in H2O2-damaged Vero cells. Ethanol precipitation of UPE_8 confirmed that UPE_8P (precipitate) had superior antioxidant activity in Vero cells compared to UPE_8S (supernatant). UPE_8P contained a large amount of polysaccharides, a major contributor to the antioxidant activity of UPE_8. This study shows that UPE_8 obtained using ultrasonication can be a functional food ingredient with excellent antioxidant activity.

Synchronous boosting adsorption and desorption efficiency is a great challenge for CO2 adsorption capture, especially for metal–organic frameworks (MOFs) having high adsorption uptakes. Herein, a novel “self‐supporting foam” strategy is proposed to fabricate a thermally conductive MOFs@boron nitride nanosheets (BNNS) composite foam (MOFs@BNNS‐PEI) via polyethyleneimine (PEI) cross‐linkage. The “rebar” BNNS and the “aggregate” MOFs are packed against each other to form a self‐supporting structure, effectively reducing the reliance on polymers to maintain high MOFs loading. Furthermore, this approach enables the successful fabrication of three different types of typical MOFs, including HKUST‐1, MIL‐100(Fe), and ZIF‐8. This unique design maintains a high specific surface area (SSA) of the MOFs foam and generates nitrogen‐rich microporosity contributing to CO2 adsorption. Additionally, PEI serves as a thermal bridge to reduce the interfacial thermal resistance between BNNS and MOFs, accelerating the thermal desorption of CO2 within the MOFs foam. Benefiting from these advantages, the MOFs@BNNS‐PEI exhibits a higher CO2 adsorption capacity (1.35–1.42 times that of pure MOFs) and a significant increase in the desorption rate for CO2 (5.0–5.7 times that of pure MOFs). Thus, the thermally conductive MOFs foam can be a viable option for efficient CO2 capture in practical applications.
