a data analytics-driven strategy for optimizing the charge mix by lowering the cost of the scrap used to prepare the molten metal while maintaining the required chemical composition, tensile strength, and hardness required by the foundry for manufacturing gray cast iron products (Grade FG 220). Th...
All measurements were performed using a Bionavis MP-SPR NaviTm 220A instrument equipped with two 670-nm laser diodes focused on two different spots on the sample surface. Both gold- and silicon dioxide-coated sensor slides were used (Bionavis). Grafting of proteins or MUTEG to the gold- and...
