Polyaniline-Coated Cobalt–Iron Oxide Composites Modified Separator for High Performance Lithium–Sulfur Batteries

“…Despite these benefits, metal oxides still exhibit limitations concerning their capacity and cycling performance. First, certain metal oxides inherently have low conductivity . Second, the mechanical stress induced by volume changes during lithiation and delithiation cycling can affect the integrity of the metal oxide material, which can lead to particle rupture, loss of electrical contacts, and overall material degradation during repeated cycles .…”

“…First, certain metal oxides inherently have low conductivity. 10 Second, the mechanical stress induced by volume changes during lithiation and delithiation cycling can affect the integrity of the metal oxide material, which can lead to particle rupture, loss of electrical contacts, and overall material degradation during repeated cycles. 11 demonstrated that conductive polymer networks can alleviate battery capacity decline by minimizing side reactions and reducing electrochemical reaction polarization.…”

Ultrasonic-assisted synthesis of magnetic recyclable Fe3O4/rice husk biochar based photocatalysts for ciprofloxacin photodegradation in aqueous solution

“… 24 As demonstrated, the ultrasonic-assisted approach has been favorable for the formation of hybrid or nanomaterials without using any additional chemical reagents or apparatus. 25 To the best of our knowledge, a simple coupling ultrasonic-assisted impregnation and precipitation is a reasonable method to produce magnetic recyclable Fe 3 O 4 /biochar photocatalysts from rice husk for ciprofloxacin photodegradation in an aqueous solution.…”

“…Jin et al [10] used reactive free radicals produced by ultrasonic irradiation to produce Mn-Ni-Fe tri-metallic oxide. Generates hierarchical pores upon anchored such tri-metallic oxide on polymer grafted carbon black which contributes to enhanced electrocatalytic performance (oxygen reduction reaction (ORR)/oxygen evolution reaction (OER)) towards rechargeable zinc-air batteries.…”
