Sentences with phrase «by electrical potential»

Oxygen ions are drawn through the electrolyte by the electrical potential and combine to O2 on the cathode side.

When the detector is illuminated — say, by a bright star — electric charges will be freed that will travel in the detector (helped by an electrical potential difference) until they are detected.

It is still a magnetic field that is responsible for the fact that the polarisation is rotated, however, it is no longer the strength of the magnetic field that determines the strength of the effect, but the amount of electrons involved in the process, and this amount can be regulated simply by electrical potential.

On Earth, the brightest auroras (the high - altitude glows often called the northern and southern lights) are generated when electrons in outer space near Earth are accelerated by large electrical potentials, or voltages, along the lines in our planet's magnetic field and slam into gas molecules in the upper atmosphere above polar regions.

With growing risks to the nation's electrical grid from natural disasters and as a potential target for malicious attacks, the U.S. Department of Energy (DOE) and the U.S. Department of Homeland Security (DHS) should work closely with utility operators and other stakeholders to improve cyber and physical security and resilience, says a new congressionally mandated report by the National Academies of Sciences, Engineering, and Medicine.

Researchers, led by Joshua Mayourian at the Icahn School of Medicine at Mount Sinai, used mathematical modeling to simulate electrical interactions between these stem cells and heart cells to develop insight into possible adverse effects, as well as to hypothesize new methods for reducing some potential risks of this therapy.

In a new study led by the University of Sussex, geoscientists from the British Geological Survey and the Technical University of Munich reveal that using a micro-seismic technique, which detects tiny earthquakes which cause cracks in the rock, alongside modern electrical imaging technology, which measures rock mass, would provide scientists with much earlier warnings of potential rock falls.

Structural magnetic resonance imaging (MRI), which measures the anatomy and structural integrity of the brain, and magnetoencephalography (MEG), which measures magnetic fields created by the brain's electrical activity, were used to track potential age - related differences as groups of younger and older adults performed a memory task.

Calculated differential electrical potential induced by a supramolecular lattice of MBB - 2 on graphene.

The team showed that by using a powerful magnetic field and very low temperatures, below — 450 degrees Fahrenheit -LRB--- 270 degrees Celsius), they could read the state of electrons in a silicon wafer, potential qubits, using electrical current, and were able to extend the usable lifetime of those qubits dramatically.

«Thermal spin generation has a potential for higher efficiency than spin generation by electrical currents.

A multiferroic can be switched on or off by applying alternating voltage — the difference in electrical potential.

He and his colleagues say the electrical potential of the device could be driven up further by improving how the gels repel the ionised atoms and by making the gel layers even thinner.

A major challenge in tapping such electrical potential is that the voltage created is tiny — a fraction of that generated by a standard AA battery.

A major challenge in tapping this electrical potential is that the voltage created is tiny — a fraction of that generated by an AA battery.

We are very excited by the potential of this material for cardiac applications but the capacity of the material to deliver physiological electrical stimuli while limiting infection suggests it might have potential in a number of other indications such as repairing damaged peripheral nerves or perhaps even spinal cord.

The new material developed by the multidisciplinary research team is composed of collagen (the most abundant protein of the human body which has known regenerative potential and can support the body's cells) and graphene (the world's thinnest material which is known to have unique mechanical and electrical properties) resulting in an electroconductive «biohybrid» combining the beneficial properties of both materials — resulting in a material which is mechanically stronger, with increased electrical conductivity.

The H - reflex is produced by an electrical stimulus, which causes action potentials to travel up afferent nerves until they synapse on α - motor neurons.

Each pulsed electrical signal sent by the CNS is called an action potential.

It is not an engine that converts heat to work, with efficiency limited by temperatures of reservoirs (see The Energy Advocate, November, 1997), but rather one that converts the electrical potential energy of the atoms into an electric current directly.

For the nearly 1.6 billion people living in communities not yet connected to an electrical grid, it is now often cheaper to install solar cells rooftop - by - rooftop than to build a central power plant and a grid to reach potential consumers.

This approach has the potential for saving money and improving overall efficiency by eliminating the intermediate and unnecessary electrical generation between the turbine and the air compressor (Gardner and Haynes 2007).
