“…The working electrode was prepared by crushing the nanofibers and dispersing them in an isopropanol-Nafion-water solution, which was drop cast over a glassy carbon electrode to form a layer of 30 μm. Electrochemical measurements revealed high sensitivity and selectivity for sensing ascorbic acid at a determined concentration of graphene foliates in the nanofiber [ 182 ].…”

Research activity on ceramic/graphene composites and hybrids has increased dramatically in the last decade. In this review, we provide an overview of recent contributions involving ceramics, graphene, and graphene-related materials (GRM, i.e., graphene oxide, reduced graphene oxide, and graphene nanoplatelets) with a primary focus on applications. We have adopted a broad scope of the term ceramics, therefore including some applications of GRM with certain metal oxides and cement-based matrices in the review. Applications of ceramic/graphene hybrids and composites cover many different areas, in particular, energy production and storage (batteries, supercapacitors, solar and fuel cells), energy harvesting, sensors and biosensors, electromagnetic interference shielding, biomaterials, thermal management (heat dissipation and heat conduction functions), engineering components, catalysts, etc. A section on ceramic/GRM composites processed by additive manufacturing methods is included due to their industrial potential and waste reduction capability. All these applications of ceramic/graphene composites and hybrids are listed and mentioned in the present review, ending with the authors’ outlook of those that seem most promising, based on the research efforts carried out in this field.

“…Recovery rates of the samples were found to be between 95.5% and 106%, indicating that ANF-C700 material can be effectively utilized for the simultaneous determination of AA, DA, and UA in the real samples analysis. Antiinterference ability of the fabricated sensor, studied in previous work [18], showed very clear amperometric signal of AA, DA and UA; while addition of common interfering compounds such as ammonium chloride,…”

The present study reports the simultaneous determination of ascorbic acid (AA), dopamine (DA) and uric acid (UA) in 0.1 M phosphate buffer solution (pH = 7.0) using a novel electrode material prepared from oxide ceramic nanofibers by applying a single step chemical vapor deposition method. Electron-transfer kinetics at the electrode/solution interface was studied by standard redox reaction of 5 mM Fe(CN) 63-/4in 1 M KCl. Electrochemical and sensing measurements such as cyclic voltammetry and differential pulse voltammetry were performed to detect DA and UA in the presence of AA. The developed electrode was shown to separate the overlapping voltammetric responses of three analytes into the individual voltammetric peaks, totally eliminate the interference from AA, and distinguish DA from UA. Linear relationship was observed between current intensities and concentrations of all three compounds, and the limits of detection (LOD) were reached 0.57 µM, 0.77 µM and 0.84 µM for DA, UA and AA, respectively. The electrode of graphenated nanofibers displayed a very good reproducibility and stability, and was successfully tested for detection of DA, UA and AA in real urine samples.

“…Where D is the diffusivity of potassium ferricyanide (6.70×10 -6 cm 2 s -1 ), A shows the surface area of the electrode(cm 2 ), k is the slope value obtained from plotting Ip Vs square root of scan rate (Vs -1 ) and n shows the number of electrons transferred during the oxidationreduction process, C is the concentration of potassium ferricyanide (4mM). For CV using Fe(CN) [3][4][5][6], the value is n=1. It was observed that SRGO modified GCE (0.0126cm 2 ) has a large electroactive surface area than bare GCE(0.0001080cm 2 ).…”

“…In the human body, AA plays a vital role in the formation of collagen, it gives shape to bones, cartilages, muscles teeth, blood vessels, and various other body parts. It also takes part in important biological reactions like the healing of injuries, iron absorption, cell development, and burns 3,4 . Nowadays, in medical research, ascorbic acid acts as a vital antioxidant agent in incurable diseases like cancer, AIDS, mental disorders, common cold, infertility, and influenza [5][6] .…”

In this research work, an electrochemical sensor has been prepared for the detection of ascorbic acid (Vit C) using a low cost and highly conductive solar radiation reduced graphene oxide (SRGO). The SRGO has been prepared using naturally available solar light for the reduction of graphene oxide. Various material characterization techniques have recognized SRGO for its morphology and conductivity. A detailed electrochemical study has been performed to test the applicability of SRGO for ascorbic acid sensing. SRGO modified electrode shows a quick response time (~2s) and ascorbic acid was detected over a narrow linear range of 20µM to 360 µM. The developed sensor also shows a high sensitivity of 114 µAmmol-1cm-2 and a lower limit of detection 56 (µM) for the ascorbic acid sensor. These results indicate that SRGO could be applied for the electrochemical study of vitamin C in food and vegetable samples.
