In this study, electrochemical molecularly imprinted sensors were fabricated and used for the determination of ascorbic acid (AA). Nanofiber membranes of cellulose acetate (CA)/multi-walled carbon nanotubes (MWCNTs)/polyvinylpyrrolidone (PVP) (CA/MWCNTs/PVP) were prepared by electrospinning technique. After being transferred to a glass carbon electrode (GC), the nanofiber interface was further ...

Two graphene materials, TRGO-1 and TRGO-2, prepared by the thermal exfoliation/reduction at 1000oC of two graphite oxides with different characteristics, are investigated as positive electrodes in a Vanadium Redox Flow Battery (VRFB). A detailed study of their electrochemical response towards the [VO2]/[VO] redox system is carried out through cyclic voltammetry, electrochemical impedance spectr...

Inhibitory effect of extracts from three date varieties namely khalt (kha), Lassiane (La) and Tadmamt (Td)), and the mixture of date varieties as environmentally friendly corrosion inhibitor for carbon steel in 1M HCl is studied by means of electrochemical tests such as electrochemical impedance spectroscopy (EIS), and Tafel polarization. It's been obtained that in 1.0 M HCl solution the date e...

Lithium-iron-orthosilicate is one of the most promising cathode materials for Li-ion batteries due to its safety, environmental brightness and potentially low cost. In order to produce a low cost cathode material, Li2FeSiO4/C samples are synthesized via sol-gel (SG; one sample) and solid state (SS; two samples with different carbon content), starting from Fe (III) in the raw materials (lo...

LiMn2O4 spinel cathode materials have been successfully synthesized by solid-state reaction. Surface of these particles were modified by nanostructured LiFePO4 via sol gel dip coating method. Synthesized products were characterized by thermally analyzed by Thermogravimetric and Differential Thermal Analysis(TG/DTA), X-Ray Diffraction (XRD), Scanning Electron...

A new anti-corrosion compound, Melamine Formaldehyde (MF), was formulated by the addition of proper amount of formaldehyde to melamine under specific conditions. This compound was mixed with a novel nano powder, which was extracted from corn cob ash containing SiO2 particles, in order to improve its corrosion inhibition efficiency. This inhibitor provides a high level of protection f...

Inexpensive, simple and quick detection of pathogen antigens in human samples is a key global health objective. Limiting factors include the cost and complexity of diagnostic tests that utilize antibody probes. Herein, we present a method for label-free electrochemical detection of a protein from the enteric pathogen Entamoeba histolytica using cell-free yeast-embedded antibody-like fragments (...
