A new nanofiber filter hints at a world where carbon capture hides inside every ceiling vent, quietly scrubbing indoor air while trimming electricity bills. Researchers say this small, silent layer ...

Abstract: In this study, we demonstrate a robust nonvolatile memristor based on polyethylenimine (PEI) with thermally stable resistive switching behaviors by doping silver ions. This polymeric ...

Abstract: This work studies the use of thin layers of polyethylenimine (PEI) as an interface film to produce electron selective contacts for photovoltaic applications in crystalline silicon. Generally ...
