Neutral atoms have equal numbers of protons (which are positively charged) and electrons (which are negatively charged). Ions are formed when atoms lose or gain electrons. If there are more electrons than protons, then an anion is formed with a negative...
Upper limits on dark matter annihilation with the teraelectronvolt cosmic ray spectrum of electrons and positrons from DAMPE We have used teraelectronvolt cosmic ray spectrum of electrons and positrons data from DArk Matter Particle Explorer (DAMPE) to estimate the upper limits o... M Wechakama...
When comparing the activities of Cr, Mn, Co and Fe MN4 complexes for ORR as a plot of (log i/n)E versus the M(III)/(II) formal potential of the catalyst (n = number of electrons involved in the ORR), two linear correlations are obtained: one for Cr, Mn and Fe complexes ...

The intensity of the oxygen signal was tracked as a function of cycle number at FC and full discharge (Fig.3). The data in Fig.3reveal an overall loss in the total amount of trapped O2in the charged cathodes over cycling, with a 44% loss from the 2nd FC to the 100th FC. Further...

At the acceptor side of PSI, NADP+ is reduced to NADPH by accepting electrons from P700 P680 through ferredoxin in the luminal side and ferredoxin-NADP+ of PSII. Together, these reductase. reactions aOre2 itseprmroedduc'pehdovtioastyhnethoextiidcaetiloenctorof nHt2rOanbsypooxritd', iaznedd...
As the fourth state of matter, plasma can introduce new excited particles and large numbers of ions into combustion system to generate new reaction paths. For example, the high-energy electrons/ions can collide with oxygen molecules to generate oxygen atoms, thus generating dynamic effects. More...
