Not exact matches

Our cells break down the sugars, and the electrons flow through them in a complex set of chemical reactions until they are passed on to electron - hungry oxygen.

Likewise, the ratio of electrons to protons can not vary by more than 1 part in 10 to the 37th power or else electromagnetic interactions would prevent chemical reactions.

Likewise, the ratio of electrons to protons can not vary by more than 1 part in 1037 or else electromagnetic interactions would prevent chemical reactions.

On the extremely small scale, however, the push and pull of electrons and protons is what controls chemical reactions, including every compound and every process in your body.

The transfer of electrons during a chemical reaction in lead - acid car batteries produces a potential of more than 2 volts.

Physics and chemistry professor Ahmed Zewail and his colleagues at the California Institute of Technology married two previously independent lines of research: femtochemistry, in which pairs of brief laser pulses initiate and monitor a chemical reaction, and electron diffraction, in which a molecule's structure is determined from the scatter of electrons fired at a crystal containing billions of copies of that molecule.

When a photon strikes an electron in a leaf, the electron delivers it to another molecule dubbed the reaction center, which converts that light into chemical energy to feed the plant.

One of the most ubiquitous is the «octet rule,» which states that each atom in a molecule that is produced by a chemical reaction will have eight outer orbiting electrons.

The team thinks one reason their technique is so efficient is that a chemical reaction between the hydrogen plasma and air molecules in the chamber's atmosphere generates cyano radicals — carbon - nitrogen molecules that have been stripped of their electrons.

Scientists have succeeded in «filming» inter-molecular chemical reactions — using the electron beam of a transmission electron microscope (TEM) as a stop - frame imaging tool.

The idea is, you have your active molecules on the surface, and you excite electrons down in the solid with ultraviolet light so that they rise up to the surface molecules to drive chemical reactions.

The aggregate effect of the chemical reactions taking place within the electrolyte creates a flow of electrons between the anode and the cathode, resulting in the discharge of electricity.

Tolstikhin and his colleagues are working in the field of attophysics — a science which looks at very fast processes (1 attosecond, as = 10 ^ -LRB--18) s) such as the restructuring of electron shells or the displacement of atomic nuclei in molecules during chemical reactions.

This is unusual, as manganese atoms typically are known to give up two or more electrons, or no electrons, in chemical reactions, but not just one.

While the chemical reaction that the bacteria perform on uranium is a common process known as «reduction,» or the act of accepting electrons, Kerkhof said it's still a mystery how the reduced uranium produced by this microorganism ultimately behaves in the subsurface environment.

Inside a battery, chemical reactions involving a material called an electrolyte cause electrons to accumulate in the negative terminal, or anode, and flow when it's connected to the positive terminal, or cathode.

Living cells thrive by exploiting similar imbalances in nature — of protons, and also electrons, which are exchanged in chemical reactions between oxidants and reductants.

In artificial photosynthesis systems chromophores, or «photosensitizers,» absorb light energy and transfer electrons to the catalyst, which activates the chemical reaction.

These processes are the key to understanding chemical and biochemical reactions, as it is the «redistribution» of electrons that is involved in the formation of new chemical bonds.

Such targeted interventions in chemical reactions have not been possible until now, since the time scale of electron movement in molecules was previously unreached.

«We used intense beams of X-rays, electrons and infrared light to study the chemical reactions taking place in the diamond cell.»

Chemically, metals including toxic metals are distinguished from non-metals by their capacity to lose electrons, forming positively charged ions, in a chemical process called an oxidation - reduction or redox reaction.
