What is the charge of potassium? What are protons, electrons, and neutrons? If the charge on the atom is 0, what does this mean? How many electrons would it take to equal the mass of a proton? What is the charge on the barium ion?

The transfer of a hydrated proton between water molecules in an aqueous solution is accompanied by the large-scale structural reorganization of the environment as the proton relocates, giving rise to the Grotthus mechanism1. Due to the complexity of the liquid phase, the infrared (IR) spectroscopy...
Because parity symmetry (invariance under the spatial inversion (x, y, z) → (−x, −y, −z)) is violated only in the weak interaction, it provides a tool with which to isolate the weak interaction and thus to measure the proton’s weak charge1. Here we report the value 0...
Hdenotes the heavy CP-even neutral Higgs boson of the model. The collider center of mass energy is chosen to bes=1400GeV as the second stage of CLIC operation. In this case,mH+<s/2can be explored due to the pair production. It is shown that the signal of charged Higgs in the mass...

proton stability, while the higgs doublet mass matrix has a massless pair eigenstate with realistic hierarchical yukawa couplings to quarks and leptons. the supersymmetry breaking scale is constrained to be high, consistent with the non observation of supersymmetry signals at the lhc. similar content ...
IT has recently been suggested by Bondi and Ly ttleton1,2 that the magnitudes of the electric charges on the proton and electron may differ by a little more than one part in 1018, in which case electrostatic forces would cause the universe to expand. In
In this work, I develop a descriptor-based activity model for CO2RR to CO with an explicit account for the electrochemical interface. The focus on CO2RR is due to two reasons. First, previous studies have revealed significant electric double-layer effects, stressing the urgency of this extension...
