Subdural electrodes [PDF]

open access: yesClinical Neurophysiology, 2010
Subdural electrodes are frequently used to aid in the neurophysiological assessment of patients with intractable seizures. We review the indications for these, their uses for localizing epileptogenic regions and for localizing cortical regions supporting movement, sensation, and language.

An Overview on Reversible Sea Return Electrodes for HVDC Links

open access: yesEnergies, 2023
HVDC electrodes are usually implemented in HVDC links to avoid the installation of a metallic return. Submarine cables, especially those dealing with lengths of thousands of kilometers, are expensive, and high costs of laying are normally expected.

Progress on carbon for electrochemical capacitors

open access: yesBattery Energy, 2023
Electrochemical capacitors bridge the energy gap between conventional dielectric capacitors and batteries. The energy storage mechanism relies on purely physical electrical double‐layer charging (EDL) and the faradaic process involving fast ...

Differentiation of roughness and surface defect impact on dielectric strength of polymeric thin films

open access: yesIET Nanodielectrics, 2020
Increasing the dielectric strength of polymer films has been a key theme as it is directly responsible for increasing energy density of relevant components such as film capacitors and insulation tapes.

Ferroelectric Phase Transitions in Ultra-thin Films of BaTiO3 [PDF]

open access: yes, 2007
We present molecular dynamics simulations of a realistic model of an ultrathin film of BaTiO$_3$ sandwiched between short-circuited electrodes to determine and understand effects of film thickness, epitaxial strain and the nature of electrodes on its ...

Electrochemical detection of TNT at cobalt phthalocyanine mediated screen-printed electrodes and application to detection of airborne vapours [PDF]

open access: yes, 2013
We describe the use of cobalt phthalocyanine as a mediator to improve the sensitivity for the electrochemical detection of TNT. Commercial screen-printed electrodes containing cobalt phthalocyanine were employed for determination of TNT.
