is fabricated through a template-engaged redox reaction followed by vacuum dehydration. This material exhibits high reversible capacity, excellent rate capability, and out standing high-rate cyclability. The outstanding performance is attributed to the fast capacitive charge storage and the in situ formed copper with enhanced electrical conductivity.

Carcinoembryonic antigen (CEA) is a broad-spectrum biomarker, and its accurate detection and analysis is important for early clinical diagnosis and treatment. This study aimed to develop a highly sensitive and selective sandwich-type immunosensor based on electrochemical impedance spectroscopy (EIS) for the accurate detection of CEA. A novel composite material, gold nanoparticle/reduced-graphene oxide/graphitic carbon nitride (AuNPs/rGO/g-CN), was synthesized with excellent electrical conductivity and a large specific surface area to immobilize biological probes.

Electrode material capacities and cycle performances must improve for large-scale applications such as energy storage systems. Numerous investigations have developed cathode materials to improve lithium-ion batteries (LIBs) performance: however, few have examined new anode materials. In this study, we synthesized a Ni-B/reduced graphene oxide (RGO) composites via a simple chemical reaction method to enhance the stability of electrodes in LIBs.

This study develops a graphene oxide-nano zerovalent iron (GO-nZVI) composite for the efficient removal of tetracycline and ciprofloxacin from water. The composite was synthesized using sugarcane bagasse as the matrix for graphene oxide (GO) and Sal leaf extract to reduce iron into nano zerovalent iron (nZVI). Microscopic analysis confirmed multiple GO layers with nZVI particles on their surface, while XRD and Raman spectroscopy verified the crystalline nature of the composite.
