The Competition between 4-Nitrophenol Reduction and BH₄⁻ Hydrolysis on Metal Nanoparticle Catalysts

Molecules, 2023
Assessing competitive environmental catalytic reduction processes via NaBH4 is essential, as BH4− is both an energy carrier (as H2) and a reducing agent. A comprehensive catalytic study of the competition between the borohydride hydrolysis reaction (BHR,

12C+12C reactions for Nuclear Astrophysics [PDF]

EPJ Web of Conferences, 2023
12C fusion reactions are among the most important in stellar evolution since they determine the destiny of massive stars. Over the past fifty years, massive efforts have been done to measure these reactions at low energies. However, existing data present

Investigating the predicted breathing-mode excitation of the Hoyle state

Physics Letters B, 2022
Knowledge of the low-lying monopole strength in C12—the Hoyle state in particular—is crucial for our understanding of both the astrophysically important 3α reaction and of α-particle clustering. Multiple theoretical models have predicted a breathing mode

The role of Fission in the search of the Super Heavy Land: Fission modes in heavy and superheavy nuclei. Case study of 180Hg [PDF]

EPJ Web of Conferences
Many observations strongly support the hypothesis that nuclei may fission through several independent fission modes (multimodal fission) interpreted as different prescission shapes and fission paths in a multidimensional potential energy landscape where ...
