A chemical reaction can be understood in detail at the quantum state-resolved level, through a combined study of molecular crossed beam experiments and theoretical quantum molecular reaction dynamics simulations.
At a single collision condition, the molecular crossed beam apparatus is able to detect the scattering angle-resolved product with rotational state-resolution. Whereas, with accurate global potential energy surface, quantum reactive scattering theory is able to predict the corresponding reactive scattering information.
Efficient Strategy to Obtain High-Quality Perovskite Single Crystals
Multiple-cation and mixed halide (FAMACs) perovskites developed by adding Br/MA/Cs ions into the FAPbI
3 perovskites are known to be the ideal compositions for use in high-efficiency photovoltaic and photoelectronic devices thanks to their reduced hysteresis, suppressed ion migration, and improved stability.

Researchers propose testing standards for particulate photocatalysts in solar fuel production
Utilization of renewable solar energy is crucial for addressing the global energy and environmental concerns and achieving sustainable development. In this regard, photocatalytic water splitting has attracted significant interest as a cost-effective means to convert sustainable solar energy into valuable chemicals.
However, because efficiency is sensitive to reaction conditions and experimental setup, it is difficult to compare the results obtained by different research groups or provide a reliable guide for large-scale implementation. Due to the lack of testing standards, it is difficult to compare the results obtained by different research groups or provide a reliable guide for large-scale implementation.
