Summary: A novel NiS/carbon nanofibers (CNFs)/porous carbon composite, synthesized using lotus leaves as a biomass carbon source, demonstrates remarkable electromagnetic wave absorption properties. The composite exhibits a minimum reflection loss of -67.65 dB at a thickness of 2.32 mm and covers almost the entire Ku band with a wide effective absorption band of 5.9 GHz at a thin thickness of 2.07 mm. In addition, under an incident angle of 31 degrees, the radar cross-section reduction value of LNSF-600 can reach 42.88 dBm2.

Summary: The study demonstrates that nonwoven carbon fibers in CNT/FELT play a more significant role than just maintaining the structure of CNT network, influencing Li+ intercalation into the CNTs and therefore affecting electrode performance. By adjusting the composition of CNT materials, the Li specific capacity and Faradaic efficiency of the electrode can be modified.

Summary: Inspired by the hydrophobic mechanism of lotus leaf, hydrophobic starch blending films based on starch-based graphite oxide carbon (S-GOCs) were synthesized with the addition of nano calcium carbonate (nano-CaCO3) and hydrophobic plasticizer (acetyl tributyl citrate, ATC). The addition of S-GOCs significantly increased the water contact angle and decreased the moisture content and water vapor permeability of the films. Further addition of nano-CaCO3 and ATC enhanced the waterproof properties of the films. The hydrophobic mechanism of the starch blending films was illustrated through surface free energy analysis and characterization of AFM and FTIR.

Summary: In this study, carbon nanofibers (CNF) were treated with fresh neem leaves (FNL) and their dispersion treatment using Triton X-100 was investigated. The results showed that the CNF morphology remained intact after organic treatment, and the CNF was functionalized with heteroatoms and nutrients from FNL. The modified CNF exhibited good electrocatalytic activity for oxygen reduction reaction (ORR) in alkaline medium, and the cup-stacked CNF showed the most active sites for the ORR catalysis.

The modified battery using GF@Fe-N/S-CNFs exhibits excellent electrocatalytic activity and higher energy and voltage efficiencies than the blank battery. It can also run smoothly at high current density and maintain excellent energy efficiency during charge-discharge cycles.

Summary: In this study, a highly transparent, flexible, and ultrathin piezocomposite was fabricated by embedding electrospun poly(vinylidene fluoride-co-trifluoroethylene) nanofibers and aerosol-synthesized single-walled carbon nanotubes in an elastomer matrix. The piezoelectric layer of the piezocomposite was composed of the poly(vinylidene fluoride-co-trifluoroethylene) nanofiber mat, while the transparent conductive electrode was formed by a single-walled carbon nanotube film. The use of these one-dimensional nanomaterials resulted in a piezocomposite with high transparency, low diffusion of light, and enhanced mechanical properties. Additionally, the combination of the piezo- and flexoelectricity exhibited by the electrospun nanofibers and the acid-doping effect on the single-walled carbon nanotubes significantly improved the kinetic energy-harvesting performance, with a maximum output voltage of 26.8 V. Moreover, the employed electrospinning and aerosol chemical vapor deposition methods are simple, scalable, and cost-effective, which are expected to accelerate the development of industrially feasible next-generation wearable electronics.
