The study of natural cellular materials offers valuable insights into the superior properties and functions underlying their unique structure and benefits the design and fabrication of advanced biomimetic materials. In this study, we present a systematic investigation of the mechanical behavior of fresh and oven-dried pomelo peels. Density measurements revealed the gradient structure of the pomelo peel, which contributed to its mechanical properties. Step-by-step drying revealed two types of water in the peel. Both uniaxial compression and low-strain hysteresis tests were conducted, and the results showed that fresh pomelo peel exhibits soft elastomer-like behavior, while dried pomelo peel behaves more like conventional synthetic polymer foam. Compared to fresh pomelo peel, dried peel samples showed higher compressive modulus and energy loss in 6, 8 and 10% strain hysteresis tests. The rehydration process was studied using hysteresis tests at three different strains. In addition, multilayer gradient EO/EO and LDPE/LDPE film/foams with 16 alternating layers were produced using the microlayer coextrusion technique. The morphology and mechanical properties were examined and indicated great potential for biomimicking the structure and properties of pomelo peel.

Background: Pomelo albedo peel byproducts are composed of many health-ben-eficial phytochemicals during processing. This study aimed to maximize the potential of incorporating pomelo albedo powder as a bioactive ingredient in pasta.

Methods: In the present study, pomelo albedo was fortified with pasta at five different con-centrations (0, 3, 6, 9, and 12%), and its effects on the antioxidant, functional, textural, and sensorial attributes of pasta were investigated.

Article Synopsis
  • Layered double hydroxides (LDHs) are promising materials for supercapacitor electrodes due to their high theoretical specific capacity, but they suffer from poor electrical conductivity and underperformance.
  • Researchers developed NNCLDH@OPC electrodes by synthesizing heterostructure foams combining NiCo-LDH and Ni(OH) on a carbon support derived from pomelo peels, which enhances performance.
  • The resulting electrodes achieved an impressive specific capacity of 3290 F/g with good stability over 4000 cycles, and when used in an asymmetric supercapacitor, they demonstrated high energy and power densities, indicating great potential for practical applications.

The development of highly catalytic activity, low-cost and environmentally friendly catalysts is crucial for the use of advanced oxidation processes (AOPs) to treat organic pollutants. In this study, to reduce costs, enhance catalytic activity and avoid secondary pollution form metal ions, pomelo peel was used as raw material, combined with surface crystallization, carbon layer protection and heat treatment technology to effectively construct AOPs catalyst that can efficiently activate peroxymonosulfate (PMS) to degrade harmful organic pollutants. Under the optimal conditions, the Co/BC-PMS system can degrade about 100 % of tetracycline (TC, a spectral antibiotic) within 5 min, and the degradation rate of TC can still reach 100 % even if Co/BC (cobalt anchored on biochar) was reused for 6 times.
