Vibrational signature of hydrated protons confined in MXene interlayers
Nature Communications, 2023 Intercalation of protons in 2D materials plays a major role for several applications in energy storage and conversion. Here, the authors show that protons intercalated in Ti_3C_2T_x MXene interlayer during electrochemical cycling have a different ...

Polarized Proton-Proton Bremsstrahlung [PDF]
Physical Review Letters, 1986 Abstract A proton-proton bremsstrahlung experiment recently carried out at TRIUMF with polarized protons gives results which disagree with the Soft Photon Approximation and agree with potential model calculations.

Cancers, 2015 In addition to the physical advantages (Bragg peak), the use of charged particles in cancer therapy can be associated with distinct biological effects compared to X-rays. While heavy ions (densely ionizing radiation) are known to have an energy- and charge-dependent increased Relative Biological Effectiveness (RBE), protons should not be very ...

Acceleration of petaelectronvolt protons in the Galactic Centre [PDF]
Nature, 2016 Galactic cosmic rays reach energies of at least a few petaelectronvolts (of the order of 1015 electronvolts). This implies that our Galaxy contains petaelectronvolt accelerators (‘PeVatrons’), but all proposed models of Galactic cosmic-ray accelerators ...

Proton Equatorial Pitch Angle Distributions in Jupiter's Inner Magnetosphere
Geophysical Research Letters, 2023 We use data from the plasma and energetic particle instruments on the Juno spacecraft, JADE and JEDI, to study the equatorial pitch angle distributions of energetic protons within Jupiter's inner magnetosphere during Juno's prime mission from 2016 to ...

The Proton-Proton Interaction [PDF]
Physical Review, 1950 This paper presents a phenomenological analysis of the proton-proton scattering observed at 32 and 340 Mev in terms of static nuclear potentials. Comparison of these results with the neutron-proton scattering at 40, 90, and 280 Mev analyzed previously indicates that nuclear forces are not charge independent. In particular, there is definite evidence in
