The combination of hydrodynamic focusing with embedded capillaries in a microfluidic device is shown to enable both surface enhanced Raman scattering (SERS) and electrochemical characterization of analytes at nanomolar concentrations in flow. The approach utilizes a versatile polystyrene device that contains an encapsulated microelectrode and fluidic tubing, which is shown to enable straightfor...

Cochlear implants are prosthetic devices used to provide hearing to people who would otherwise be profoundly deaf. The deliberate addition of noise to the electrode signals could increase the amount of information transmitted, but standard cochlear implants do not replicate the noise characteristic of normal hearing because if noise is added in an uncontrolled manner with a limited number of el...

conclusions ma is nowadays the most accurate stereotactic anatomic guide for targeting the human na. it is a representative example of how stereotactic microanatomy could serve the development of stereotactic microneurosurgery. following the currently used trajectory through the alic, a dbs electrode placement within the na, targeting the ma, is feasible, allowing either na or alic stimulation....

a carbon nanocomposite electrode has been designed by incorporation of montmorillonite nanoclayinto the carbon ionic liquid electrode for the electrochemical determination of amitriptiline . the surface ofthe proposed electrode was characterized by scanning electron microscopy. the presence of ionic liquid asa binder is believed to be responsible for the electrocatalytic activity of the propose...

CONCLUSIONS The present experimental set-up of high spatial resolution cone-beam computed tomography (CBCT) showed advantages of demonstrating the critical landmarks of the cochlea in identifying the position of intracochlear electrode contacts and has the potential for clinical application in cochlear implant (CI) surgery. OBJECTIVE To evaluate a newly developed CBCT system in defining CI el...

keep the abstract under 1⁄2 of a page) Phantom limb pain adversely affects 64% of amputees and most treatment options are ineffective. The long term goal of my research is to develop a non-invasive, home-based therapy for treating phantom limb pain. This proposal focuses on the development of mathematical models for predicting effective electrode configurations and stimulation parameters in ord...

Due to the two-dimensional confinement of electrons, single- and few-layer MoSe₂ nanostructures exhibit unusual optical and electrical properties and have found wide applications in catalytic hydrogen evolution reaction, field effect transistor, electrochemical intercalation, and so on. Here we present a new application in dye-sensitized solar cell as catalyst for the reduction of I₃(-) to I(-)...

This work explores the synergistic combination of ionic self-assembly and recognition-directed assembly for the modification of electrode surfaces with redox glycoenzymes on the basis of electroactive glycopolyelectrolyte-surfactant complexes.

The mixing process of electrode-slurry plays an important role in the electrode performance lithium-ion batteries (LIBs). dispersion state conductive materials, such as acetylene black (AB), directly influences electronic conductivity composite electrodes. In this study, relation between and internal resistance was investigated combination with characterization electrode-slurries by rheological...

The combination of graphene and nickel oxide nanoparticles yields nanostructured electrochemical sensor formed a novel kind of structurally uniform and electrocatalytic activity material. In cyclic voltammetry studies, in the presence of epinephrine, nickel oxide / graphene  composite modified electrode shows a significantly higher current response for epinephrine oxidation. Based on differenti...
