Methyl(trifluoromethyl)dioxirane (TFDO) can be used for the oxyfunctionalization of SWCNTs filled with NaI and LuCl₃ under mild conditions. The chosen metal halides are of interest for theranostics, both for imaging and therapy when in their radioactive form. The applied functionalization methodology does not require metal catalyst, preserves the integrity of the nanotubes during treatment, avo...

Biomass materials are promising precursors for the production of carbonaceous materials due to their abundance, low cost and renewability. Here, a freestanding wrinkled carbon membrane (WCM) electrode material for flexible supercapacitors (SCs) was obtained from flower petal. The carbon membrane was fabricated by a simple thermal pyrolysis process and further activated by heating the sample in ...

ronment, the determination of trace Hg(II) is important. Atomic absorpt ion and inductively coupled plasma spectroscopic methods are currently widely used. Many publications on this subject focus on electrochemical methods (anodic and potentiometric stripping voltammetry) at a variety of electrode materials. Glassy carbon, goldplated glassy carbon, screen-printed carbon, platinum (Pt) and gold ...

a carbon-paste electrode (cpe) chemically modified with the n-4,4'-azodianiline(ferrocenyl schiff base) complex and multi wall carbon nanotubes (adafcnte) was used as a highly sensitive electrochemical sensor for determination of trace amounts of atenolol. the oxidation peak potentials in cyclic voltammogram of adafcnte occurred around 550 mv vs ag/agcl (at ph 6.0) while this peak potentia...

Gas diffusion electrode was used for providing better conditions in fuel cell systems for oxygen reduction reaction (ORR). Because the slow kinetics of the oxygen reduction reaction at the proton exchange membrane fuel cell cathode restricts fuel cell efficiency. To this end, researchers have used platinum-coated carbon. In the present study, due to the reduction of carbon corrosion, Zinc oxide...

Electrochemical oxidation of quercetin, as an important biological molecule, has been studied in non-aqueous media using cyclic voltammetry, electrochemical impedance spectroscopy and scanning electron microscopy. To investigate the electrochemical properties of quercetin, an important flavonoid derivative, on a different surface, a new glassy carbon electrode has been developed using dithiooxa...

The electrochemical behaviour of electrodes and of complete solid-state supercapacitors has been studied by cyclic voltammetry (CV) and alvanostatic charge/discharge (CD) measurements using two independent electrochemical equipments. The first one controlled the execution of he test and recorded the voltage and current values of the complete supercapacitor while the other one recorded the poten...

Advanced Ceramics find wide range of industrial applications. Cutting of advanced ceramic (SiC) is very difficult using conventional machining methods due to its low fracture toughness. In the past few years, researchers have claimed successful machining of ceramic composites using EDM process. Furthermore, increasing trend, necessity of miniaturization, micro components in MEMS and semiconduct...

In this study, the performance and reaction location in a VRFB was investigated with a carbon paper electrode that was modified to include a thin layer of multi-walled carbon nanotubes. The nanotube layer was introduced into the electrode at locations on the negative and positive electrode nearest the membrane and nearest the flow field. Results with the nanotube layer on the positive electrode...

The redox activity of a chitin film on a glassy carbon electrode was remarkably improved by the addition of carbon powder to the film in the detection of ascorbic acid, flavin adenine dinucleotide (FAD) and nicotinamide adenine dinucleotide (NADH). Although oxidation of ascorbic acid using the electrode with the chitin film did not give an appreciable voltametric response, the addition of carbo...
