c-VACNT™ - structures are made with a combination of non-proprietary and proprietary manufacturing process steps including photolithographic patterning of catalyst wafers, VACNT growth, carbon infiltration, separation from a growth substrate, optional secondary coating and/or other local or global surface modifications. The c-VACNT™ material of which these structures are made of has a nano-carbon based bi-continuous phase structure with 20-100 nm wide slit pores that are mechanically stable despite being semi-flexible so that they can survive drying after soaking in acetone or water soaking. They presently can be up to 5 mm tall and have features and/or through channels, notches, branches, arms as well as internal or external shapes ranging in size from 5 μm to over 100 mm.

We present here examples of selected fluid reactor applications demonstrating how these c-VACNT™ structures can be used to significantly improve the performance of medical and industrial devices, including extracorporeal membrane oxygenators (ECMOs) and artificial lungs.
