A deterministic processing method is a high-precision finishing method, where the to-be-removed amount of material at each point of the work surface is calculated based on an accurately measured present surface shape and is removed precisely using a numerically controlled (NC) processing system. Although this method has achieved nanometer-scale accuracy, the method requires considerable time to scan the work surface, leading to low productivity. Therefore, using an individual on-off controllable array-type plasma generator covering the entire work surface, enabling simultaneous NC plasma processing is proposed herein.

- The research details the synthesis of bifunctional C2-symmetric 7,7'-dihydroxymethyl-8,8'-biquinolyl using a two-step process involving copper/palladium catalysis and palladium(II)-catalyzed oxidation.
- The final product exhibits stable axial chirality, and optically active versions of the compound were obtained through chiral column separation or further oxidation of a precursor.
- The chirality of the enantiomers was confirmed using the exciton chirality method, ensuring the understanding of their absolute stereochemistry.
