Protonated nitriles are particularly stable by virtue of the very large hydrogen atom affinities of their radical cations.doi:10.1002/jms.4462Nick A. van HuizenJohn L. HolmesPeter C. BurgersJournal of Mass Spectrometry
The possible cosmological variation of the proton-to-electron mass ratio μ = m p /m e was estimated by measuring the H2 wavelengths in the high-resolution spectrum of the quasar Q 0347-382. Our analysis yielded an estimate for the possible deviation ofμ value in the past, 10 Gyr ago:...
Proton and Electron Mass-Energy Equivalence to Displaced Vacuum Energy By: Ray Fleming Abstract Two of the great mysteries of physics are..
√s = 7 TeV with the ATLAS experiment; studies of the ATLAS electron identification performance using J/y →e+e and Z →e+e decays in proton-proton collision data at √s = 7 TeV; a data driven method for extracting the pp→Z+X background in the low mass Higgs→ZZ() →4 region....
Antiprotonic atoms are first formed by the collision of an incident antiproton with a single or multiple bound atomic electrons. After one of these collisions, if the kinetic energy of the antiproton is similar to the electron binding energy, it can be captured by the residual Coulomb potential...
Dense ceramic high-temperature inorganic mixed proton and electron conducting membranes consist of a ceramic solid oxideproton conductorand an electron conducting second phase, which could be a ceramic or a high-temperature resistant metal, for example, Pd, Ni, or an alloy. First studies by Iwahara...
When the proton-transfer exothermicity is large, internal energy can appear in the protonated product that may be sufficient to cause dissociation with the loss of one or more neutral fragments. Thus, as was the case with dissociative electron-transfer reactions, the product ions again provide a...

This indicates that the catalyst degradation may not be the bottleneck, but that low mass and proton transports are rather the barriers of the processes. Therefore, the stability of the catalyst region, where it has simultaneous access to the electron, proton and mass phases (or the so called...
Micromorphology, elemental distribution, and d-spacing of polymer segments were evaluated via scanning electron microscopy (SEM, SU-8010, Hitachi, Japan), energy-dispersive X-ray spectrometry (EDX), wide-angle X-ray diffraction (WAXD, R-AXIS RAPID), and small angle X-ray scattering (SAXS). ...
