Neurosurgical therapeutic interventions include components that are presumed to be therapeutically inert, such as craniotomy and electrode implantation. Because these procedures may themselves exert neuroactive actions, with anecdotal evidence suggesting that craniotomy and electrode placement may have a particularly significant impact on epileptic seizures, the importance of their inclusion in...

The deconvolution of physicochemical processes in impedance spectra SOCs with nickel/ceria fuel electrodes is challenging as gas diffusion strongly overlaps the electrochemical at and air electrode. To overcome this issue, symmetrical cells were applied process electrode was quantified by altering inert component (nitrogen/helium) a ternary mixture. An effective transport parameter considering ...

The occurrence of paroxysmal narcotic episodes including psychotic-like symptoms in divers participating to experimental deep diving programs with various gas mixtures has constituted, beyond the classical symptoms of the high-pressure neurological syndrome, the major limitation for deep diving. With the development of new saturation deep diving programs and experiments by the eastern nations, ...

A getter/electrode assembly has been devised to suppress the regeneration mechanism of the electron cloud effect in the arc dipoles of LHC. The assembly consists of a copper foil electrode, supported through an insulating layer on a stainless steel skid, which would rest upon the flat bottom of the beam screen. The electrode is coated with NEG to provide effective pumping of all non-inert gases...

The aim of this study is to investigate the optimization process parameters for Metal inert gas welding (MIG). In the present work, bead-on -plate welds were carried out on MS 5986 Fe 410 carbon steel sheets using Gas Metal Arc Welding (GMAW) process. In this present investigation ER70S-6 solid wire having 1.2 mm diameter was used as an electrode with direct current electrode positive polarity....

Cysteine-containing peptide oxidation was studied both by using an inert platinum electrode and a sacrificial electrode (copper or zinc) generating metallic ions in electrospray ionization mass spectrometry (ESI-MS). Using peptides containing one, two and three cysteines, we have compared the different chemical and electrochemical oxidation pathways of cysteine (RS(-II)H) to cystine (RS(-I)S(-I...

The method of spray depositing PEDOT:PSS allows the fabrication of thin films with controlled thickness on polymer layers. PEDOT:PSS is used in inverted ITO/TiO2/P3HT:PCBM/PEDOT:PSS/Ag solar cells to optimize the work function of the hole collecting electrode. The interlayer is also found to protect the organic layer during metal top deposition and improve the contact between P3HT PCBM and the ...

A plate−gap model of a porous enzyme doped electrode covered by a porous inert membrane has been proposed and analyzed. The two−dimensional−in−space mathematical model of the plate−gap biosensors is based on the reaction−diffusion equations containing a nonlinear term related to the Michaelis−Menten kinetics. Using numerical simulation of the biosensor action, the influence of the geometry of t...

Poly(methylene blue) modi®ed electrodes have been prepared by potential cycling from aqueous electrolyte solution containing methylene blue on glassy carbon substrates. They have been used successfully for the determination of haemoglobin via its electrooxidation at ®xed potential using the batch injection analysis technique in which whole blood samples diluted with phosphate or acetate buffer ...

Resistive-switching devices based on Metal–Insulator–Metal (MIM) structures have shown promising memory performance characteristics while enabling higher density of integration. Usually, these MIM devices are fabricated using different processing conditions including high temperature thermal treatments that could lead to undesirable chemical reactions in the insulator material and at its interf...
