Layered double hydroxides (LDHs), also known as hydrotalcite-like anionic clays, have been investigated widely as promising electrochemical active materials. Due to the inherently weak conductivity, the electrochemical properties of LDHs were improved typically by utilization of either functional molecules intercalated between LDH interlayer galleries, or proteins confined between exfoliated LD...

Dental alloys as CoCrMo, SS 316L stainless steel and NiTi were electrochemically investigated in artificial Fusayama saliva, unmodified and modified with two different concentrations of natrium fluoride. Electrochemical tests include measurements of open circuit, measurements of linear polarization, potentiodinamic polarization curves and electrochemical impedance spectra. The best electrochemi...

calcareous deposits formed on the part of steel that cathodic reactions occur on their surface. the purpose of this research is an investigation of the effect of potential on crystal form of the calcareous deposits and effect of them on the corrosion resistance of the mild steel in natural seawater. the electrochemical tests such as impedance and polarization tofel tests were used in order to i...

in this paper, the effect of cationic and anionic ion sizes on the charge storage capability of graphene nanosheets is investigated. the electrochemical properties of the produced electrode are studied using cyclic voltammetry (cv) and electrochemical impedance spectroscopy (eis) techniques in 3m nacl, naoh, and koh electrolytes. scanning electron microscopy (sem) is used to characterize the mi...

Clinical analyses benefit world-wide from rapid and reliable diagnostics tests. New tests are sought with greatest demand not only for new analytes, but also to reduce costs, complexity and lengthy analysis times of current techniques. Among the myriad of possibilities available today to develop new test systems, amperometric biosensors are prominent players-best represented by the ubiquitous a...

In this study silicon-multi walled carbon nanotube (Si-MWCNT) lithium ion battery anodes were produced and their electrochemical galvanostatic charge/discharge tests were conducted at various (25 ◦C, 35 ◦C, 50 ◦C) temperatures to determine the cyclic behaviors of anode at di erent temperatures. Anodes were produced via vacuum ltration and DC magnetron sputtering technique. Silicon was sputtered...

The Nucleus cochlear implant has been shown to give substantial communication benefit to the severe to profoundly deaf. Future cochlear implants will incorporate an advanced multi-channel electrode array, which will enable better sound-coding strategies to be implemented. This new electrode array will be fabricated using state-of-the-art micromachining technology. Any long-term implanted device...

Electrochemical machining is one of the most effective methods in machining of hard and complex shapes. As a result, it is a very good candidate for inside rifle machining. In this paper the principles and mathematical modelling, the results of computer simulation and experimental investigations of electrochemical rifling tool are presented. From this point of view, a rifling tool in electroche...
