Hydrogen Tunneling in Stoichiometric and Catalytic Reactions involving Transition Metals
ChemCatChem, Volume 15, Issue 24, December 19, 2023., 2023 An overview on the importance of the participation of hydrogen tunneling in E−H bond activation reactions (E=C, O, Si…) mediated by transition metals is presented. Understanding when hydrogen tunneling occurs can be a powerful tool for designing new catalysts to perform challenging reactions.

Prospect for measurements of (γ, n) reaction cross-sections of p-nuclei at ELI-NP
Frontiers in Astronomy and Space Sciences, 2023 The gamma beam system under construction at the ELI-NP facility in Romania is projected to give the nuclear physics community access to an experimental system providing a high-intensity, narrow bandwidth photon beam at variable energy.

Mergers of Binary Neutron Star Systems: A Multimessenger Revolution
Frontiers in Astronomy and Space Sciences, 2021 On August 17, 2017, less than two years after the direct detection of gravitational radiation from the merger of two∼30 M⊙ black holes, a binary neutron star merger was identified as the source of a gravitational wave signal of ∼100 s duration that ...

Big bang nucleosynthesis [PDF]
Nuclear Physics B - Proceedings Supplements, 1999 The concordance of standard big bang nucleosynthesis theory and the related observations of the light element isotopes (including some new higher \he4 abundances) will be reviewed. Implications of BBN on chemical evolution, dark matter and constraints on particle properties will be discussed.

Nucleosynthesis in O-Ne-Mg Supernovae [PDF]
, 2007 We have studied detailed nucleosynthesis in the shocked surface layers of an Oxygen-Neon-Magnesium core collapse supernova with an eye to determining if the conditions are suitable for r process nucleosynthesis.

QUÍMICA ESTELAR E ESTRELAS APOCALÍPTICAS: ESTUDO COMPARATIVO
Colloquium Exactarum, 2012 All atoms existing in the Universe, except Hydrogen (H) and helium (He), arise from processes occurring in stars and their evolution. The stars transmute the H and He in other heavier elements through nuclear fusion and its process rolling, filling and ...
