This paper presents a novel method to fabricate temperature sensor arrays by dispensing a graphite-polydimethylsiloxane composite on flexible polyimide films. The fabricated temperature sensor array has 64 sensing cells in a 4×4 cm2 area. The sensor array can be used as humanoid artificial skin for sensation system of robots. Interdigitated copper electrodes were patterned on the flexible polyi...

A series of chromium oxides (Cr2O3) nanoparticles supported on different carbonaceous material, namely: graphene, graphene oxide (GO) and graphite, were synthetized by precipitation the salt precursors with precipitant (ammonia) subsequent thermal treatment. The catalytic activity these composites Cr2O3 have been analysed Koutecky-Levich (KL) rotating ring-disc electrode methods results discuss...

3D Carbon Microelectrodes In article number 2100102, Suresh Mamidi and co-workers fabricate carbon–metal oxide composite electrodes on graphite-coated substrate evaluate its electrochemical performance as an anode in lithium-ion batteries. Here, microelectrodes shorten the Li+ ions’ diffusion paths. Graphite coating at base provides efficient electron-conducting pathways whereas cobalt nanopeta...

ABSTRACT. For the first time, silver nanoparticles (AgNPs) were fabricated with graphite pencil electrode (GPE) by immersing a bare hard black (HB pencil) in AgNO3 solution mixed extract Quercus infectoria solution, followed placing directly against to UV lamp (254 nm) and kept for 30 min. Silver modified-GPEs characterized X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dis...

Macroscale and nanoscale measurements of epinephrine electro-oxidation at graphite electrodes, with different step edge densities, demonstrate unequivocally that the reaction occurs readily at the basal surface, and that step edges are not required for molecular electrocatalysis, in contrast to the current literature model.

Potassium ion batteries (KIBs) are emerging notably due to the reversible K+ intercalation into graphite. So far, optimization of graphite electrode formulation remains, however, be investigated. This work thus proposes optimize ionic (porosity) and electronic percolation networks as well mechanical properties electrodes for KIBs. To do so, carbon black amount (CB) calendering is first adjusted...

A novel in situ electrochemical reconstruction occurs in NiV3O8/natural graphite electrodes, which results in excellent electrochemical performance. After repeated rate performance from 0.16 to 3.1 A g(-1) over 320 cycles, the specific capacity can restore well and shows no obvious attenuation in the subsequent 360 cycles.

Graphite was electrochemically exfoliated in mixtures of room temperature ionic liquids and deionized water containing lithium salts to produce functionalized graphenes and such an electrochemical exfoliation technique can be directly used in making primary battery electrodes with significantly enhanced specific energy capacity.

The Embedded Electrode Hall Effect Thruster is a modified 10 kW T-220HT with embedded graphite electrodes within the channel wall to study ion focusing for improved thrust-to-power ratio. Previous experiments with the thruster have demonstrated increased performance on xenon with biased electrodes caused by increases in ion energy, propellant efficiency, and a reduction in the plume divergence ...
