An In-Situ Thermal Conductivity Probe
1980It was the aim of this investigation to develop and test a probe for in-situ thermal conductivity measurements also applicable for rocks. First a new theory for a spherical probe for absolute measurements was developed. A sensor including the spherical probe (heater) and a downhole hydraulic drilling mechanism for drilling well defined special side ...

Calibration of magnetic probes in the vicinity of a conducting well
Review of Scientific Instruments, 2008Measuring magnetic fields near the edge of a plasma device can be complicated by the geometric effects of the ports through which such measurements are made. The primary effect is an attenuation of the magnetic field at the probe coil due to the field expanding into the finite sized conducting well of the port.

A six-ring probe for monitoring conductivity changes
Physiological Measurement, 2005This paper presents the construction of a six-ring probe for monitoring immittance changes. The spatial sensitivity of the probe is defined. This is used to examine the uniqueness of the probe in terms of its application to monitoring conductivity changes. A spatial distribution of the sensitivity is presented for isotropic and anisotropic cases.

Conducting Polymers as Antennas for Probing Biophysical Activities
The Journal of Physical Chemistry B, 2008Conducting polymers can serve as soft electrode substrates for anchoring and orientating functional membrane proteins. We utilize this possibility to orient bacteriorhodopsin (bR), a membrane protein that functions as a light-driven proton pump, on these substrates.

Nuclear Spins as Probes for Conduction Electrons
1990Due to the short correlation time of conduction electrons at the nuclear sites the ensemble averages of the hyperfine interaction are observed. The nuclear magnetic resonance frequency is shifted by the polarization of the electrons (Knight shift) and the electron spin resonance frequency is shifted by the polarization of the nuclei (Overhauser shift).

Probing Intraband Conductivity Dynamics in Graphene
International Conference on Ultrafast Phenomena, 2010We use ultrafast optical spectroscopy to investigate intraband conductivity dynamics in a graphene monolayer grown by chemical vapor deposition, revealing the effect of the conical band structure on two-dimensional Dirac quasiparticles.

Development of conducting high polymer probe
Synthetic Metals, 2001This paper presents a novel conductive high polymer probe for the testing of high-density printed wiring boards. For this application, technologies for producing fine probes with low resistances are developed. We combined photosensitive acrylate and pyrrole, which upon oxidization and development produced conductive polypyrrole probe.

Probing Colossal Ion Conductivity Hypotheses
ECS Meeting Abstracts, 2018Fuel cells have long promised to bring high efficiency to the production of energy. In practice, fuel cells have been limited to hydrogen systems, where the high diffusivity of hydrogen through membranes allows high current densities. Hydrogen based fuel cells pose three major limitations: the requirement of expensive catalysts, the expensive or ...

Conductance coefficients for multi-probe conductors
Solid State Communications, 1991A general formula is derived which expresses the conductance coefficients of a multi-probe conductor in quasi-stationary fields in terms of dynamic correlation of the asymptotic current operators in the leads. The formula fulfils reciprocity relations of the Onsager type and can be considered as the global version of the well known fluctuation ...
