Two inexpensive and simple methods for synthesis of carbon nanodots were applied compared to each other, namely a hydrothermal microwave-assisted method. The synthesized characterized using transmission electron microscopy (TEM), ultraviolet-visible (UV-Vis), photoluminescence (PL), Fourier transform-infrared spectroscopy (FTIR), X-ray diffraction (XRD). microwave had smaller particle size thus...

In this work, the novel design of a sliding mode TriboElectric Nano Generator (TENG)—which can utilize vibration amplitude few hundred microns to generate useful electric power—is proposed for first time. Innovative features include motion modification amplify relative displacement TENG electrodes and use biological material-based micron-sized powder at one increase power output. The is designe...

The bovine serum albumin (BSA) protein is employed in genosensors as nonspecific binding blocker. In this work, the influence of BSA on electrochemical response a DNA-based biosensor explored by impedance spectroscopy (EIS) and double pulse voltammetry technique. Each buffer component hybridization studied bare gold electrodes single-stranded DNA (ssDNA)-functionalized electrodes. found to have...

Surface modification of boron-doped diamond (BDD) with copper phthalocyanine was achieved using a simple and convenient dropcast deposition, giving rise to a microcrystalline structure. Both unmodified and modified BDD electrodes of different surface terminations (namely hydrogen and oxygen) were compared via the electrochemical reduction of oxygen in aqueous solution. A significant lowering of...

A paramount role of surface structure and composition on the kinetics of electrocatalytic reactions has been realized with the establishment of electrocatalysis as a science. Consequently, a variation in the surface structure, and a modification of surface composition is expected to result in a considerable alternation of the electrocatalytic properties of electrodes. Reliable data on the role ...

Thermal poling using microstructured electrodes on oxyfluoride glasses have been investigated and the impact optical properties was evaluated. A micrometer refractive index modification based sodium fluorine migration has evidenced, through creation of a layer with different chemical composition as compared to original glass. Topological modifications after treatment are discussed. For first ti...

A highly sensitive amperometric Prussian blue-based hydrogen peroxide sensor was developed using 3D pyrolytic carbon microelectrodes. printed multielectrode electrochemical cell enabled simultaneous reproducible blue modification on multiple electrodes. The effect of oxygen plasma pre-treatment and deposition time electrodeposition studied. response 2D sensors to the addition in ?M sub-?M conce...
