Flocculation using selected cationic polymers reduces high‐risk host cell proteins in monoclonal antibody processes already during primary recovery

open access: yesBiotechnology Progress, EarlyView.
Flocculation using cationic polymers leads to the creation of large floc complexes. Negative charged species like cells, cell debris, and negatively charged host cell impurities like host cell DNA and host cell proteins are trapped within the complex while the positively charged monoclonal antibody stays in solution.

Strongly‐Anchored Ionomer‐Free Anode Catalyst Layer Fabricated via Joule Heating Achieves Efficient Electron/Mass Transfer for Acidic Water Electrolysis

open access: yesCarbon Energy, EarlyView.
An ionomer‐free anode catalyst layer is fabricated via rapid Joule heating, partially embedding IrO2 nanoparticles into the membrane to form a robust, anchored interface. This architecture eliminates ionomer‐induced poisoning and mass‐transport barriers, enabling efficient water‐mediated proton transport and electronic connectivity.
