A modified hierarchical control structure for distributed generation (DG) in microgrid is applied accordance to the recommendations by IEEE Std. 1676. In inverter layer, a generalized algorithm developed enable DGs operate all three modes (i.e., grid-forming, grid-feeding, and grid-supporting modes) with single structure, facilitating seamless transition between operating modes. This feature obtained designing multiloop controller layer using inverse plant modeling techniques so that...

Intraoperative fluorescence navigation can illuminate the tumor, directing surgeons to accurately achieve negative margins, which not only reduces recurrence but also minimizes incidence of complications. Herein, we developed two near-infrared fluorescent probes FAPI-Cy7-Cl (Emmax = 820 nm) and (FAPI)2-Cy7-Cl 823 with prolonged tumor retention (>72 h) high target-to-background ratios (up 4.5) based on conjugation pan-cancer targeted fibroblast activation protein inhibitor (FAPI)...

Electrolyte-gated, printed field-effect transistors exhibit high charge carrier densities in the channel and thus on-currents at low operating voltages, allowing for low-power operation of such devices. This behavior is due to area-specific capacitance device, which electrolyte takes role dielectric layer classical architectures. In this paper, we investigate intrinsic double-layer capacitances ink-jet electrolyte-gated inorganic both in-plane top-gate architectures by means...

Abstract Electrolyte‐gated transistors (EGTs) represent an interesting alternative to conventional dielectric‐gating reduce the required high supply voltage for printed electronic applications. Here, a type of ink‐jet printable ion‐gel is introduced and optimized fabricate chemically crosslinked by self‐assembled gelation, without additional crosslinking processes, e.g., UV‐curing. For poly(vinyl alcohol) poly(ethylene‐ alt ‐maleic anhydride) are used as polymer backbone chemical...
