The Photophysics of Nucleic Acids: Consequences for the Emergence of Life
ChemSystemsChem, Volume 5, Issue 1, January 2023., 2023 Photochemical reactions in nucleic acids induced by ultraviolet (UV) radiation could have played an important role in the prebiotic selection of the building blocks of life. This Review summarizes the quantum efficiencies of the photorelaxation pathways of nucleic acids and discusses its implications for the emergence of an initial sequence pool on ...

Experiment regarding magnetic fields with gravity
IET Quantum Communication, Volume 3, Issue 4, Page 218-228, December 2022., 2022 Abstract This experiment was designed to test the string theory as a physical reality. The ground‐based device placed the N poles of the magnets upwards, north, south, east, and west. Coil Ass'Y was placed between 2 N poles with bearing covers on the top and bottom.

Nuclear astrophysics and underground accelerators
Physics of the Dark Universe, 2014 AbstractAccurate knowledge of thermonuclear reaction rates is a key issue in nuclear astrophysics since it is important for understanding the energy generation, neutrino production and the synthesis of the elements in stars. Cross-section measurements are mainly hampered by the very low counting rate and cosmic background.

Nuclear astrophysics with neutrons [PDF]
Journal of Instrumentation, 2012 Neutrons play a crucial role in astrophysics during the heavy element nucleosynthesis. The largest fraction of isotopes heavier than iron is produced by neutron capture processes on short (r process) and long timescales (s process). During the ``slow neutron capture process'' (s process) heavier elements are produced by successive captures of in-situ ...
