Abstract: Thermally triggerable polymer films that degrade at modest temperatures (≈85 °C) are created from a blend of cyclic polyphthalaldehyde (cPPA) and a polymeric thermoacid generator, poly(vinyl tert-butyl carbonate sulfone) (PVtBCS). PVtBCS depolymerizes when heated, generating… read more here.

Abstract: Fully-cycled depolymerization and repolymerization of a low ceiling temperature polymer, cyclic poly(phthalaldehyde) (cPPA), yielding high performance structural polymer is demonstrated. The facile conditions for cPPA depolymerization circumvent the extreme conditions required to break down and… read more here.

DOI: 10.1186/s13756-019-0665-5
Abstract: BackgroundPseudomonas aeruginosa is a common pathogen causing hospital-acquired infections. Carbapenem resistance in P. aeruginosa is either mediated via a combination of efflux pumps, AmpC overexpression, and porin loss, or through an acquired carbapenemase. Carbapenemase-producing P.… read more here.
