EPJ Web of Conferences, 2018 The r-process nucleosynthesis in the Universe is constrained by observations of chemical abundances of the Solar System and those of old stars that should record the products of the r-process events in the early Universe. This review provides a brief overview of the observational technique to determine chemical abundances of stars.

The Origin of r-process Elements in the Milky Way [PDF]
The Astrophysical Journal, 2018 Abstract Some of the heavy elements, such as gold and europium (Eu), are almost exclusively formed by the rapid neutron capture process (r-process). However, it is still unclear which astrophysical site between core-collapse supernovae and neutron star–neutron star (NS–NS) mergers produced most of the r-process elements in the universe ...

β-delayed Fission in r-process Nucleosynthesis [PDF]
The Astrophysical Journal, 2018 Abstract We present β-delayed neutron emission and β-delayed fission (βdf) calculations for heavy, neutron-rich nuclei using the coupled Quasi-Particle Random Phase Approximation plus Hauser-Feshbach (QRPA+HF) approach. From the initial population of a compound nucleus after β-decay, we follow the statistical decay, taking into account ...

Recent advances in microbial capture of hydrogen sulfide from sour gas via sulfur‐oxidizing bacteria
Engineering in Life Sciences, 2021 Biological desulfurization offers several remarkably environmental advantages of operation at ambient temperature and atmospheric pressure, no demand of toxic chemicals as well as the formation of biologically re‐usable sulfur (S0), which has attracted ...
