Uranyl, a strong Lewis acid, forms stable complexes with relatively hard donors and it is commonly believed that uranyl complex with trialkylamine is stabler than trialkylphosphine. However, there are no thermodynamic parameters to evaluate the complexation stabilities of R 3 N-UO 2 2+ and R 3...

The evaluation and analysis of barriers that restrict the large-scale development of shale gas are beneficial to the selection of a scientific and reasonable development model. The objective of our study was to reveal the key barriers to the large-scale development of shale gas in China. Sixteen...
