Atomically Precise Cu Nanoclusters with Thermally Activated Delayed Fluorescence Properties.

Ligand-stabilized metal nanoclusters with atomic precision are considered to be promising materials in the field of light-emitting and harvesting. Among these, nanoclusters with thermally activated delayed fluorescence (TADF) properties are highly sought after. While several gold and silver nanoclusters with TADF properties have been reported in recent years, research on copper counterparts has significantly lagged behind.

Ligand effects in photoluminescence of copper nanoclusters.

Copper nanoclusters have attracted significant interest in the field of materials science due to their high abundance, complex structure, and unique properties. However, there is a limited amount of research on the relationship between structure and properties. In this study, we synthesized and comprehensively characterized two new Cu nanoclusters, [Cu(PhSe)(PPhO)] (Cu9-1) and [Cu(CHOPhS)(PPhO)] (Cu9-2), in order to investigate the effect of ligands on photoluminescence.

Pancreatic Cancer Mortality in China: Characteristics and Prediction.

Objectives: During the last decade, the mortality rate of pancreatic cancer in China has significantly increased. We analyzed data for the period 1991-2014 to investigate the distribution of mortality rates and predict trends for the next 5 years.

Methods: We obtained the pancreatic mortality data from the Chinese cancer annual report.
