Oxygen recombination in individual pressure vessel nickel-hydrogen batteries [PDF]

open access: yes, 1986
A metal-hydrogen cell is described which avoids damage and retards flooding of the hydrogen electrodes by providing for chemical recombination of oxygen and hydrogen in areas or sites remote from the hydrogen electrodes.

Using electropolymerization based doping for electro-addressable functionalization of a multi-electrode array probe for nucleic acid detection [PDF]

open access: yesarXiv, 2017
Here, we report a facile method for electro-addressable functionalization of a probe comprising of closely spaced three individually addressable carbon fiber electrodes for detection of nucleic acids. First, a multi electrode array probe comprising three adjacent carbon fiber electrodes was fabricated through pulling a three-barrel glass capillary with

Quantifying the effect of electrical conductivity on the rate-performance of nanocomposite battery electrodes [PDF]

open access: yesarXiv, 2019
While it is well-known that electrode conductivity has a critical impact on rate-performance in battery electrodes, this relationship has been quantified only by computer simulations. Here we investigate the relationship between electrode conductivity and rate-performance in Lithium-Nickel-Manganese-Cobalt-Oxide (NMC) cathodes filled with various ...

Hyperthermia heating apparatus [PDF]

open access: yes, 1982
Electromagnetic energy is delivered to a localized area of a patient's body in a hyperthermic treatment so that it provides a uniform distribution of electromagnetic flux lines within the localized area of the patient's body and produces a uniform and ...

Multi-Channel Soft Dry Electrodes for Electrocardiography Acquisition in the Ear Region

open access: yesSensors
In-ear acquisition of physiological signals, such as electromyography (EMG), electrooculography (EOG), electroencephalography (EEG), and electrocardiography (ECG), is a promising approach to mobile health (mHealth) due to its non-invasive and user ...

Insulated ECG electrodes [PDF]

open access: yes, 1973
Insulated, capacitively coupled electrode does not require electrolyte paste for attachment. Other features of electrode include wide range of nontoxic material that may be employed for dielectric because of sputtering technique used.

Magneto-transport in impurity-doped few-layer graphene spin valve

open access: yes, 2010
Using Keldysh nonequilibrium Green's function method we study the spin-dependent transport through impurity-doped few layer graphene sandwiched between two magnetic leads with an arbitrary mutual orientations of the magnetizations.

Multistage depressed collector for dual mode operation [PDF]

open access: yes, 1981
A depressed collector which captures the spent electrons of a microwave transmitting tube at high efficiency in both high and low power modes of operation is described. The collector comprises entrance and end electrodes, the end electrode having a spike

Resistive and rectifying effects of pulling gold atoms at thiol-gold nano-contacts

open access: yes, 2006
We investigate, by means of first-principles calculations, structural and transport properties of junctions made of symmetric dithiolated molecules placed between Au electrodes.
