"Unraveling the Origins of Cerium in the Universe: A Scientific Investigation"

Scientists at CERN's Neutron Time-of-Flight facility have conducted a study to investigate the production of cerium in stars. Their findings, published in Physical Review Letters, reveal discrepancies between theoretical models and observational data, indicating a need to revise the mechanisms responsible for cerium production in the universe. The study's results have significant astrophysical implications, suggesting a 20% reduction in the contribution of certain processes to the abundance of cerium in the universe and requiring a paradigm shift in the theory of cerium nucleosynthesis.

Cerium boosts visible light absorption of titanium dioxide.

Researchers from the Chinese Academy of Sciences have improved visible light absorption in Ce/TiO2 by doping cerium in the TiO2 lattice, resulting in a high photocurrent density and better separation efficiency of photogenerated electrons and holes. The study presents a practical strategy for developing efficient visible light-activated rare earth-doped photocatalysts. Ce doping into the TiO2 lattice improved the separation efficiency of photogenerated electrons and holes, resulting in high photocurrent density and incident photon current efficiency (IPCE).
