A series of TiO 2 nanotube arrays (TNAs) with different diameters and roughness were prepared by electrochemical anodization method by changing the fluoride ion concentration [0.4%, 0.3%, 0.2% (mass)] and applied voltage (15, 25, 35, 45 V). The scanning electron microscopy (FESEM) and atomic force microscopy (AFM) results showed that the wall thickness of the prepared TNAs increased and the roughness decreased with the decrease in fluoride ion concentration in the electrolyte. The effects of surface roughness and diameter on the surface mechanical properties of TNAs and the interaction of Cytochrome C (Cyt C) were studied by AFM characterization. The results show that the adhesion is proportional to the contact area. With the increase in the diameter of the TNAs, the wall thickness decreases; the effective contact area between TNAs and Cyt C increases first and then decreases; the forces of Cyt C with TNAs also increase first and then decrease. The roughness decreases when the diameter is fixed; the effective area of TNAs increases; the interaction force also increases. It can be seen that the surface roughness and effective contact area of TNAs can be effectively controlled by changing the fluoride ion concentration of the electrolyte, which is further beneficial to promoting the interaction with protein molecules.

A coupled scheme of coupled cyclone with built-in granular bed filter (C-CGBF), combining the centrifugation and filtration in one device, is designed for dry gas purification in a wide range of application temperature. The static pressure distribution in the C-CGBF is measured under the fixed bed operation regime. The results reveal that there is an apparent relation between the swirling intensity and the inlet gas velocity, according to the static pressure distribution in the annular space of the C-CGBF. The influence of the negative pressure core and the vortex flow field in the C-CGBF is no longer distinct below the measuring point N8 ( H = 2 175 mm). The static pressure distribution of the device shows a clear asymmetric distribution in the circumferential direction, which also reflects the uneven distribution of the gas phase flow in the device in the circumferential direction.
