In the present study, a novel carbon-carbon composite electrode was prepared by embedding activated carbon derived from chickpea pods and evaluating its potential as an electrode for supercapacitors. A simple, single-step electrospinning technique was used for the synthesis of activated carbon-carbon nanofiber composite. The synthesized activated carbon-carbon nanofiber composite electrode is flexible and binder-free with high specific surface area, micro and meso pores, interconnected fiber-to-flake morphology and possess high graphitization. Additionally, rapid electrolyte diffusion has resulted in a low charge transfer resistance due to interconnected morphology. In 6 M KOH electrolyte, composite binder-free electrode shows a specific capacitance of 147 F g-1 at 0.5 A g-1 compared to activated carbon electrodes that showed a specific capacitance of 120 F g-1 at 0.5 A g-1. It exhibits an energy density of 13 Wh k g-1 at 0.366 W k g-1 power density. It also showed impressive cyclic stability by retaining 93.5 % of initial capacitance till 1200 cycles at 1 A g-1. Overall, the study presents an easy-to-use, low-cost, eco-friendly, and flexible electrode for supercapacitors that is free of binder.

Virus-like particle (VLP) vaccines are powerful immunostimulants that efficiently trigger robust B-cell and T-cell responses, specifically enhancing the activity of dendritic cells. The integration of nanoparticles, particularly carbon-based nanomaterials (CBNs), with these VLPs, has opened new horizons in creating targeted, durable, and potent immune responses. This innovative approach may be pivotal in formulating therapeutic vaccines against notoriously challenging pathogens, including HIV. Functionalized CBNs have shown the potential to amplify cellular uptake, fostering a highly specific immune activation. The employment of VLP vaccines in conjunction with CBNs has sparked intensive research efforts, with a major focus on nanostructure functionalization for augmenting immune response specificity and strength. In this meta-review, we synthesize, critique, and discuss the current landscape of VLP-based vaccines and CBNs as a dynamic vaccine platform. The goal is to strategize the prevention and treatment of various viral infections, with a special focus on coronaviruses and HIV, paving the way for next-generation antiviral therapeutics.

The published paper was produced from a poorly-edited file which resulted in numerous typographical and grammatical errors, leading to confusion about the experiments and results reported. The paper has been edited and the corrected version is shown here.
