Ferroelectric materials have attracted a lot of attention for several decades due to wide applications such as non-volatile random-access memories and large piezoelectric responses for sensors and transducers. [1][2][3] However, the proper ferroelectrics have been restricted to a relatively narrow range of compositions where the ferroelectric state emerges from the specific electronic configurations for orbital hybridization or the second-order Jahn-Teller ions to break the space-inversion

Highlights d Some bronchiectasis patients exhibit increased airway abundance of Neisseria spp. d The culturable species N. subflava weakens barrier integrity and induces inflammation d N. subflava elicits distinct transcriptomic/metabolipidomic signatures in the mouse lung d Neisseria-associated pathogenic signatures are observed in bronchiectasis patients Authors
