One of the key questions associated with the function of cytochrome c oxidase is how the transfer of electrons and protons is coupled and how proton transfer is controlled by the enzyme. In this study we focus on the function of one of the proton transfer pathways of the R. sphaeroides ...
Capture of Argon K -Shell Electrons by 2.5- to 12-MeV Protons Using coincidence techniques, we have measured the cross section for capture of electrons from the K shell of argon atoms by protons in the energy range fr... JR Macdonald,CL Cocke,WW Eidson - 《Physical Review Letters》 被引...
Electric currents are not always flows of electrons, they can be flows of any type of electric charge. The type of charge-carrier depends on the type of conductor. Both protons and electrons possess exactly the same amount of 'electricity.' If either the protonsorthe electrons flow, that flo...

Tables for Born Approximation Calculations of K- and L- Shell Ionization by Protons and Other Charged Particles Tables are presented for the calculation of the Born cross sections for ionization by proton impact of K - and L -shells and of individual L -subshells in ... GS Khandelwal,BH Ch...
Abstract —By the methods of atomic force microscopy (AFM) we investigate the surfaces of samples of K-208 glass after separate and combined irradiation in a vacuum chamber with a residual pressure of p v = 104 Pa with protons and electrons with energies of 20 and 30 keV, respectively. At...
might be exploding stars, for example. Such violent events make electric and magnetic fields, which can speed up protons (质子) and electrons. Those fast particles can then produce gamma rays with a lot of energy. That can happen when protons interact with other matter in space, for example...
摘要: Polycrystalline samples of amino acids and proteins were exposed to electrons and beams of helium, carbon, neon, and argon ions from the Berkeley heavy-ion linear accelerator. Both the irradiations...关键词: n20310* --chemistry--radiation & nuclear chemistry-- radiation effects acetic ...
·O2−radicals. Compared to oxygen production via four-electron process, these species are formed easily via two-electron process, beneficial to produce a large-scale source of electrons and protons for water reduction. Therefore, the Co-P/BP nanosheets exhibit robust hydrogen-evolving activity ...
X-ray Production by 1.5–11 MeV Protons K -shell ionization and L x-ray production cross-sections by proton impact have been determined from measurements of K x-ray yields from thin targets of ... R Akselsson,TB Johansson - 《Zeitschrift für Physik A Hadrons and Nuclei》 被引量: 83发...
