A novel electrochemical sensor was proposed for the determination of amitriptyline based on the copper oxide (CuO) nanoparticles modified graphite screen-printed electrode. CuO nanoparticles were used to enhance the surface area of the electrode and then improve the sensitivity of the electrochemical sensor. Amitriptyline electrochemical response characteristics of the modified electrode in a p...

This paper describes unusual graphite–sulfide deposits in ultramafic rocks from the Serranı́a de Ronda (Spain) and Beni Bousera (Morocco). These deposits occur as veins, stockworks and irregular masses, ranging in size from some centimeters to a few meters in thickness. The primary mineral assemblage mainly consists of Fe–Ni–Cu sulfides (pyrrhotite, pentlandite, chalcopyrite and cubanite), graph...

Graphite nanoplatelets have recently attracted considerable attention as a viable and inexpensive filler substitute for carbon nanotubes in nanocomposites, given the predicted excellent in-plane mechanical, structural, thermal, and electrical properties of graphite. As with carbon nanotubes, full utilization of graphite nanoplatelets in polymer nanocomposite applications will inevitably depend ...

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...

determination of 1, 1-dimethylhydrazine (dmh) in air is carried out by spectrophotometry, gc or hplc analysis, but in this study dmh was analyzed by a gas sensor based on nanostructure conducting polyaniline. determination of dmh has been done very simplely and quickly in recent work. electrically conductive fibers have been prepared by polymerization of aniline on surfaces of commercial polyme...

A homemade batch electrolytic cell with a Sn-Pb alloy cathode used to generate cadmium hydride. Several parameters influencing the electrochemical hydride generation and trapping on the coated graphite tubes, and atomization process have been investigated. Ir-, W-, and Zrcoated graphite tubes were used for trapping cadmium hydride. It was found that Ir-coated graphite provided the best sensitiv...

A polymer-coated surface acoustic wave (SAW)-based chemical sensor for organophosphorous compound sensing at extremely low concentrations was developed, in which a dual-delay-line oscillator coated with fluoroalcoholpolysiloxane (SXFA) acted as the sensor element. Response mechanism analysis was performed on the SXFA-coated chemical sensor, resulting in the optimal design parameters. The shear ...

Ceramics-coated graphite powders are considered an effective raw material to fabricate the three-dimensional continuous ceramics skeleton reinforced matrix composites which can overcome their inherent poor densification, mechanical and antioxidation properties. However, morphology thickness regulation of ceramic coatings on particles still a great challenge. Herein, SiC-coated (graphite@SiC) we...
