The validation of sterilization-grade membranes is integral to ensuring the efficient and safe use of microfiltration systems. Here validation refers to the production of sterile filtrate for sterilizing-grade membranes under challenge test conditions. Current validation methods require 48 h of culture for results to become available, which creates time delays within the manufacturing process a...

We describe experimental and theoretical results that demonstrate the feasibility of power generation using concentration cells based on ionic concentration gradients and reverse electrodialysis. A peak power density of 0.2 (0.7) lW cm 2 and a maximum energy density of 0.4 (0.4) mJ cm 3 delivered in 3 h to a 2 (5) kX resistor were recorded using a microfiltration (anion exchange) membrane, resp...
