Summary: A nanocomposite-based dual-emission fluorescent probe was developed for detecting ethylene thioureas (ETU). The probe consisted of sulfur quantum dots (SQDs) and gluta-thione stabilized gold clusters (GSH-AuNCs). The fluorescence intensities at 450 nm and 570 nm decreased due to aggregation fluorescence quenching, but the addition of ETU resulted in a partial recovery of fluorescence at 570 nm. The method showed high selectivity and sensitivity, and had good recovery of ETU in agricultural products.

Summary: There is an increasing interest in developing robust and efficient sequential methods for reservoir simulation. The sequential fully implicit Newton (SFIN) method addresses the slow sequential coupling convergence issue when flow and transport problems are strongly coupled. However, the original SFIN algorithm requires fixed primary variables during the simulation. In this work, strategies are proposed to handle inconsistent primary variables and extend the SFIN method to the natural black-oil formulation.
