In particular, synchronous cationic-anionic polymerization has been an important challenge in the field of polymer synthesis due to possible coupling termination of both chain ends. We recently found that such terminal couplings can be significantly inhibited by a bismuth salt with a strong nucleophilic anion (e.g., BiCl<sub>3</sub>) and disclosed the mechanism. Accordingly, we propose a cationic-anionic polymerization (CAP) method where cationic ring-opening polymerization (CROP) of 2-oxazolines (Ox) and anionic ring-opening polymerization (AROP) of cyclic esters (CE) can be initiated sequentially and propagated simultaneously in one-pot, using bismuth salts as the initial initiators, to afford a multifunctional copolymer polyoxazoline-<i>block</i>-polyester (POx-<i>b</i>-PCE). Furthermore, a block copolymer PAPOZ<sub>20</sub>-<i>b</i>-PCL<sub>5</sub> synthesized by CAP can self-assemble into micellar aggregates, which exhibit excellent intrinsic antibacterial activities without loading any extra antibiotic components.

Here, we demonstrate that thermal biasing can break the vertically stacked lattice symmetry of twisted bilayer graphene via the interatomic Seebeck effect, enabling thermoelectric imaging of topological edge states at tunable Fermi levels above room temperature. The high spatial resolution in the imaging is achieved through atomic-scale thermopower generation between a metallic tip and the sample, reflecting the local electronic band structure and its derivative features of twisted bilayer graphene at the Fermi level.
