General description

Copperbeads are versatile catalysts in organic synthesis and material science because of their recyclability, sustainability, and superior catalytic performance. They are employed as heterogeneous catalysts in a range of organic reactions, including Click chemistry and cross-coupling reactions.

Application

  • Spray-dried ternary bioactive glass microspheres: This study examines the structural effects of copper doping in bioactive glass microspheres, highlighting their potential in biomedical applications for controlled drug delivery (Vecchio et al., 2024).
  • Design, Synthesis, and Characterization of Stable Copper Nanofluid: Reports on the synthesis of copper nanofluids for enhanced thermal conductivity, relevant in industrial production and various thermal applications (Bhat et al., 2024).
