In a recent work we have shown that the mass of W± bosons can be computed from first principles by modeling these bosons as relativistic rotational bound states consisting of e±–νe pairs, and by employing the de Broglie wavelength equation together with Newton’s universal gravitational law but with gravitational instead of rest masses (Vayenas et al., 2016). Here, we present similar calculations for the Zo boson which we model as a bound state of e+–νe–e with an electron antineutrino at the center of the rotating ring. This appears consistent with the fact that Zo bosons are known to decay primarily to e+–e pairs. The above models contain no adjustable parameters. The computed Zo boson mass (91.72 GeV/c2), as well as the ratio of the masses of Zo and W± bosons, differ by less than 0.6% and 0.9% respectively from the experimental values.

Electrochemical promotion of the hydrogenation of CO2 on Ru deposited on a BZY proton conductor

The kinetics and the electrochemical promotion of the hydrogenation of CO2 on polycrystalline Ru deposited on BZY (BaZr0.85Y0.15O3−α + 1 wt% NiO), a proton conductor in wet atmospheres, with α ≈ 0.075, was investigated at temperatures 300–450 °C and atmospheric pressure. Methane and CO were the only detectable products and the selectivity to CH4 could be reversibly controlled between 15% and 65% by varying the catalyst potential by less than 1.2 V.
