| The strong force is the one that is dominant in the atomic nucleus, acting between the quarks inside the proton and the neutron. |
| Identical results were obtained by Willis and Szabo using tyrosine in the presence of acetate and other proton acceptors. |
| Why is it easier to accelerate an electron to a speed that is close to the speed of light, compared to accelerating a proton to the same speed? |
| Several years ago, it appeared that the only solid acids that could support high proton transport were those based on sulfates or selenates. |
| This is because the proton is made of two up quarks and a down quark, while the neutron comprises two downs and an up. |
| This indicates that the bound azide is required to detect the 410-nm signal and suggests that azide plays the role of the proton acceptor. |
