Sentences with phrase «charge between atoms»

Not exact matches

When an eel zaps its prey, positively charged potassium and sodium atoms inside and between these cells flow toward the eel's head, making each electrocyte's front end positive and tail end negative.

There is a correlation between the amount of charge on the atoms and their catalytic activity.

Proposed by Caltech geochemist Don Burnett, the idea was to put a spacecraft in orbit between the sun and Earth to collect particles of solar wind — electrically charged atoms from the sun's atmosphere blown outward through the solar system.

Of the two types of atom, oxygen has more pull on the electrons that they share to form the bonds between them, so the oxygen becomes slightly negatively charged and the hydrogens slightly positive.

The aim is to track the attosecond motions of charged clouds in and around atoms in order to better understand the fundamentals of the interaction between light and matter.

But when compounds contain unequal numbers of negatively and positively charged ions, repulsion between atoms with the same charge may drive the structure to become unstable under pressure.

Every so often, the nuclei of the two atoms would hit head on and stick, overcoming the repulsive force between positively charged protons.

When used at NIST to transmit laser light to trap ions (electrically charged atoms), the fibers reduce stray light and fluctuations in laser beam pointing and make it possible to transfer ultraviolet light between separate optical tables, the paper notes.

Super-Kamiokande uses a vast tank of extremely pure water to detect neutrinos that emerge from interactions between cosmic rays (high - energy charged particles from space) and atoms in Earth's atmosphere.

The polymers bond to biological tissues via three mechanisms — electrostatic attraction to negatively charged cell surfaces, covalent bonds between neighboring atoms, and physical interpenetration — making the adhesive extremely strong.

Each fluorine atom has so much electronic charge that you get tall peaks and deep valleys in between them, compared to the smooth plane of regular graphene.

January 23, 1997 How cells prevent suicide Researchers have shown that a mysterious protein, crucial to the survival of cells throughout the body, is able to form a channel through the internal membranes of cells, and thus may perform the vital function of selectively passing atoms or electrically charged ions between the cell's compartments.

They observed the metal atoms becoming charged ions, clustering with up to thousands of others into metal nanoparticles, and then migrating and forming a bridge between the electrodes at the opposite ends of the dielectric material.

The process they came up with inadvertently altered the structure of the carbon to great advantage — an increased overall surface area capable of holding the lithium charge and increased spacing between the carbon atoms, which allows for a faster charge by giving the lithium ions better access to each carbon atom.
