Not exact matches

The body takes electrons from food and, ultimately, transfers those electrons to oxygen inhaled by the lungs.

In multivalent batteries, lithium would be replaced by a different metal that transfers more than one electron per ion.

It consists of electron transfer to the originally ionized Ne atom matched by energy transfer away from the Ne, which leads to ionization of the second Kr atom nearby.

By demonstrating the presence of such coherence resulting from a capture of an incoherent electron, Prof. Krishnakumar and co-workers have shown that such coherence can also stem from the transfer of more than one value of angular momentum quanta.

The mysterious and lightning fast chemical reactions that transfer electrons between atoms have been impossible to observe by the naked eye.

Low temperature plasmas are one of the best media for CO2 decomposition — the split - up of the molecule into oxygen and carbon monoxide — both by direct electron impact, and by transferring electron energy into vibrational excitation.»

The electrons used from the copper to form the molecules of hydrogen are transferred by an external wire connected to the zinc.

Researchers produce such heating by aiming microwaves at the electrons gyrating around magnetic field lines — a process that increases the thermal energy of the electrons, transfers it to the ions through collisions, and supplements the heating of the ions by neutral beam injection.

Computational studies by the team's theoreticians showed that the dipeptide in the meta position was more compact, making electron transfer faster, because of the smaller energy associated with the necessary twist in the scaffolding, or the ability to get closer to the electrode.

Why it matters: Electron transfer by MtrC, an outer membrane cytochrome on S. oneidensis, can stabilize contaminants, mitigating their impact on the population and environment.
