Artificial neural network (ANN), fuzzy logic (FL) and genetic algorithm (GA) framework were chosen as the best methodologies for design, optimization and control of crude oil distillation column. It was discovered that many past researchers used rigorous simulations which led to convergence problems that were time consuming. The use of dynamic mathematical models was also challenging as these models were also time dependent. The proposed methodologies use back-propagation algorithm to replace the convergence problem using error minimal method.展开更多

A series of Eu/Gd-mixed metal-organic frameworks EuxGd（1-xNDC（x = 0.0005, 0.001, 0.003, 0.01;H2 NDC = 1,4-naphthalene dicarboxylic acid） utilizing back energy transfer have been developed for physiological temperat...A series of Eu/Gd-mixed metal-organic frameworks EuxGd（1-xNDC（x = 0.0005, 0.001, 0.003, 0.01;H2 NDC = 1,4-naphthalene dicarboxylic acid） utilizing back energy transfer have been developed for physiological temperature sensing. The suitable high triplet level of H2NDC allows an efficient back energy transfer from Eu3＋ions to ligands. The back energy transfer efficiency is further enhanced by the Eu3＋/Gd（3＋）-mixed strategy. As a consequence, the emission of Eu3＋dramatically weakens when temperature arises. The resultant Eu0.0005 Gd0.9995 NDC exhibits exceptional stability and good biocompatibility, and can detect physiological temperature in single-emission, dual-emission, and colorimetric models with ultra-high sensitivity.展开更多
