  • Understanding the physical origin on hysteresis in organic electrochemical transistors is important for achieving non-volatility. Here, the authors report a thermodynamic framework that explains the emergence of bistable device operation via the interplay of enthalpy and entropy.

  • Though models describing the operating mechanism of organic electrochemical transistors (OECTs) have been developed, these models are unable to accurately reproduce OECT electrical characteristics. Here, the authors report a thermodynamic-based framework that accurately models OECT operation.

  • Mechanistic understanding of interactions between polymer semiconductor channel and electrolyte in organic electrochemical transistors remains limited. Here, X-ray scattering and spectroscopy reveal the origin of bistability and non-volatile behavior between semiconducting PEDOT:PSS and an ionic liquid.

  • Billing et al. clarify mechanisms ensuring reliable cytokine signaling despite variable expression and activation of signaling proteins in cells. Limited activation of signaling proteins either by feedback inhibition or low cytokine doses, and STAT3 serine phosphorylation timely orchestrate robustness and capacity of IL-6-induced signaling.
