Unforgeable Red: Design and Application of SO‐Annulated Perylene Diimides for Anti‐Counterfeiting

Small, EarlyView.
Sulfoxide‐annulated derivatives were synthesized as photoactive chromophores and implemented in photopatterning processes to design anti‐counterfeiting signatures with a double level of authentication. Patterns ranging from centimeter to micrometer size were obtained with high definition, and thereafter these approaches were tested in potential market ...

Parametric Dynamic Mode Decomposition for Reduced Order Modeling [PDF]

, 2023
Dynamic Mode Decomposition (DMD) is a method by which spatial modes can be extracted from experimental or numerical data sets. DMD can be used as well to obtain a low rank or reduced operator for a physical system by singular value decomposition of ...
