The Redox operating system project has finished a grant-funded phase of work implementing ring buffer communication at the system task level, modeled on Linux's io_uring. The team built an io_uring/liburing-like API for applications, ring buffer machinery for system services and drivers, supporting async executor crates, and performance improvements to speed switching between applications and services.
A technical review examines the ferrocyanide/ferricyanide redox couple, prized in flow batteries for its stability, kinetics and solubility, and asks why no one has built a symmetric flow battery using it on both electrodes. The piece explains that ferrocyanide reacts with heavy metal cations like zinc or iron to form insoluble Prussian blue compounds, blocking the metal-plating side of such a design, and notes that even chelation workarounds using pyrophosphates lead to poor long-term cycling stability, as shown by degradation data after 100 cycles.
