Vanillin containing 9H-fluoren sulfone scaffolds were prepared by coupling a sulfone amine with carboxylic acid group of amino acids in presence of peptide coupling reagent hexafluorophosphate benzotriazole tetramethyl uronium (HBTU). All eight (6a–6h) synthesized vanillin containing 9H-fluoren sulfone scaffolds were evaluated for their biological activities, namely, antibacterial, antifungal and antimalarial. The antibacterial evaluation revealed that compounds 6b-6g exhibited potency against tested ...

Electrically controllable nonvolatile magnetic memories show great potential for the replacement of conventional semiconductor-based memory technologies. Here, we experimentally demonstrate ultrafast spin-orbit torque (SOT)-induced coherent magnetization switching dynamics in a ferromagnet. We use an ultrafast photoconducting switch and a coplanar strip line to generate and guide a ~9-picosecond electrical pulse into a heavy metal/ferromagnet multilayer to induce ultrafast SOT. We then use magneto- ...
