Multisegment nanowires represent a unique platform for engineering multifunctional nanoparticles for a wide range of applications. For example, the optical and magnetic properties of nanowires can be tailored by modifying the size, shape, and composition of each segment. Similarly, surface modification can be used to tailor chemical and biological properties. In this article, we report on recen...

Abstract Numerous catalysts have been reported with enhanced performance, e.g. longer lifetime and improved selectivity, for the electrochemical CO 2 reduction reaction (CO RR). Respectively little is, however, known about influence of electrode structuring pre-treatment on this catalytic layers. Thus, we herein report modification catalyst environment a Cu-ZnO-carbon black by variation ink com...

The possibility of obtaining a dispersed material by the method plasma dynamic synthesis in Ti-O system is shown. based on operation pulsed high-current coaxial magnetoplasma accelerator with titanium electrodes. obtained product was investigated X-ray diffraction and transmission electron microscopy. results showed presence two main oxide (IV) crystalline modifications: anatase tetragonal syng...

The present paper deals with the design of experimental work matrices for two groups of experiments by using Response surface methodology (RSM). The first EDM group was dealt with the use of kerosene dielectric alone, while the second was treated by adding the graphite micro powders mixing to dielectric fluid (PMEDM). The total heat flux generated and fatigue lives after EDM and PMEDM models we...

The overpotential of oxygen evolution reaction is 700-800 mV more positive at FTO anode than on Pt electrode. This property of FTO coating makes it attractive as an electrode material for electrochemical sensors and electroanalytical chemistry. However, oxygen transfer reactions, such as Pb and Cl oxidation, occur with considerably lower overpotential. It indicates the possibility of formation ...

Lithium ion batteries have been one of the major power supplies for small electronic devices since the last century. However, with the rapid advancement of electronics and the increasing demand for clean sustainable energy, newer lithium ion batteries with higher energy density, higher power density, and better cyclic stability are needed. In addition, newer generations of lithium ion batteries...

Polypyrrole(PPy) nanowire modified electrodes were developed by template-free electrochemical method based on graphite electrode. The modified electrode was characterized by their amperometric response towards nitrate ions. Before reduction of nitrate ions, electrochemical solid-phase extraction (EC-SPE) of nitrate in/on modified electrodes was conducted. It is found that the unusual nanowired ...

Coulometric electrodes in series have been used with liquid chromatography with electrochemical detection to increase selectivity and resolution for the direct analysis of tissue neurotransmitters. Use of three coulometric sensors for electrochemical modification, selectivity, and peak identification has been expanded into "gate" cells of three or four coulometric electrodes that allow eliminat...

BACKGROUND Electrodes for neural stimulation and recording are used for the treatment of neurological disorders. Their features critically depend on impedance and interaction with brain tissue. The effect of surface modification on electrode impedance was examined in vitro and in vivo after intracranial implantation in rats. Electrodes coated by electrophoretic deposition with platinum nanopart...
