Introduction: Graphene-based materials have gained increasing attention for use in radiation attenuation applications. In this study, pristine graphene nanoplatelet-containing (1, 3, 5, and 10 wt%) borate-based bioactive glass composites were prepared. Methods: Structural properties, Vickers microhardness, gamma-ray shielding properties of the fabricated examined detail. Results Discussion: rev...

Carbon-supported Pt nanoparticles are the leading catalysts for cathode oxygen reduction reaction (ORR) in polymer electrolyte membrane fuel cells. However, these ORR suffer from poor electrochemical durability, particularly loss of surface area (ECSA) due to nanoparticle dissolution and agglomeration. Here, is mitigated through a Pickering emulsion-processing strategy that employs graphene nan...
