CeO2C2 nanoparticles with oxygen‐enriched vacancies in‐site self‐embedded in Fe, N co‐doped carbon nanofibers as efficient oxygen reduction catalyst for Zn‐air battery

The in-u2010site dual template assisted electrospinning process and subsequent high temperature pyrolysis process have resulted in a unique CeO2C2 nanoparticles self-embedded in Fe, N co-u2010doped carbon nanofibers heterostructure catalyst. Thanks to the CeO2C2's excellent catalytic results in the ORR process, as well as versatile Fe2010N. U2010C with rich reactive species and high conductivity, CeO2C2@Fe2010C catalyst shows outstanding cycle stability and cycle stability, as shown by excellent methanol tolerance and cycle stability in the ORR process. The Znu2010C battery, manufactured with CeO2C2@Fe, offers superior results, including large open circuit voltage and high specific capacity, as well as enhanced reversibility and cycling stability, outperforming commercial Pt/C catalyst.

Improved damage sensing with random/aligned carbon nanofiber in bulk epoxy and adhesive joints

Addconductive nanofillers that provide inherent piezoresistive sensing capability in nonconductive polymers can be used to perform in situ health testing of polymeric materials and adhesive joints. Carbon nanofiber was added to epoxy in bulk and adhesive form to investigate their potential applications as strain and crack detection sensors, respectively. Tensile specimens of CNF/epoxy nanocomposites with different filler amounts were tested to determine strain sensing ability. The alignment was carried out inside the adhesive by AC electric field to investigate the alignment's effect on crack detection accuracy and joint toughness.
