Catalytic Performance Improvement in Polymer Derived Nanostructures for Fuel Cell Applications
Abstract: The performance and operational lifetime of PEMFCs are closely linked to the catalytic activity and durability of cathode electrocatalysts. In this research, a polymer-derived cobalt–iron nitrogen-doped carbon (CoFe–N/C) nanostructured catalyst is developed to enhance the ORR performance for PEMFC applications. PAN and melamine serve as nitrogen-rich polymer precursors, while cobalt and iron salts generate highly dispersed metal–nitrogen active sites within a porous carbon matrix through thermal treatment at 900 °C. …

Effect of machining parameters on the tool wear in drilling of 3D PF C/C composite
Abstract: Carbon–carbon (C/C) composites are broadly used in aerospace, defence, shipbuilding, chemical, and nuclear industries owing to their high strength-to-weight and stiffness-to-weight ratios. However, they are brittle, anisotropic and non-homogeneous in nature, making them difficult to machine. Incorrect machining parameters can cause defects such as burrs, delamination, and fibre bundles pullout. This paper aims to study the hole surface and tool wear during drilling of 3D pierced fabric (PF) carbon-carbon (C/C) …
