... two different routes for the formation of open-microcellular and open-nanoporous membrane morphologies. Porosity is introduced by expansion of carbon dioxide saturated films and hollow fibers at elevated temperatures. The microcellular structure manifests itself by small spot-like openings wit ...

... initial exposure to distilled water at 80°C. In the time scales of the experiments (up to 15 days), no evidence was found that the presence of carbon dioxide at 80°C made the water significantly more aggressive to the copper/nickel alloys. The superiority of the Cu/30Ni alloy over Cu/10Ni a ...

... 30% Ni, in distilled water. The study involved exposure of specimens to distilled water (1.5–7 µS/cm) at 20–80°C with and without injected carbon dioxide. At 20°C upon initial exposure to distilled water, the 10% Ni alloy exhibited somewhat active corrosion behaviour during anodi ...

Effects of pH conditions on the biological conversion of carbon dioxide to methane in a hollow-fiber membrane biofilm reactor (Hf–MBfR)
... Carbon dioxide is one of the global warming gases. Utilization of a sustainable energy is one of the effective technologies for the mitigation of CO ...

An atomic force microscope study of calcium carbonate adhesion to desalination process equipment: effect of anti-scale agent
Whilst carbon dioxide is water soluble the system is somewhat complex and results in the presence of carbonate anions which interact with cations such as Ca2 ...
