Modeled channel distributions explain extracellular recordings from cultured neurons sealed to microelectrodes [PDF]

open access: yes, 2002
Amplitudes and shapes of extracellular recordings from single neurons cultured on a substrate embedded microelectrode depend not only on the volume conducting properties of the neuron-electrode interface, but might also depend on the distribution of ...

CURRENT DISTRIBUTION AND INPUT IMPEDANCE OF A STRIP LOOP ANTENNA LOCATED ON THE SURFACE OF A CIRCULAR COLUMN FILLED WITH A RESONANT MAGNETOPLASMA [PDF]

open access: yesProgress In Electromagnetics Research B, 2013
We study the electrodynamic characteristics of a strip loop antenna located on the surface of a circular column fllled with a resonant magnetoplasma and surrounded by a homogeneous isotropic background medium. The antenna current is excited by a time-harmonic voltage creating an electric fleld with the azimuthal component in a narrow gap on the strip ...

An improved Carbon-Coating Method for LiFePO4/C composite derived from Fe3+ precursor

open access: yesInternational Journal of Electrochemical Science, 2012
In this paper, a novel hydroxyethylcellulose (HEC)-assisted carbon-coating method was developed to synthesize LiFePO4/C composites. The structure and morphological transformation of the as-prepared samples were studied using a combination of X-ray ...
