A reactor cell for measuring gas and liquid permeation is disclosed. The reactor cell comprises a reactor module having a reactor chamber and a cover. A first hole extends into the reactor chamber from a first surface, a second hole opposing the first hole extends into the reactor chamber from a second surface, a third hole extends into the reactor chamber from a third surface and a fourth hole opposing the third hole extends into the reactor chamber from a fourth surface. A hollow fiber is supported by and sealed into the first and second holes of the reactor module. The first and second ends of the hollow fiber are sealed with a sealing solution. Methods for making and using the reactor cell are also disclosed. As made and used, the reactor cell further comprises a molecular sieving membrane grown on an inner bore surface of the hollow fiber.

Described are single-walled metal oxide nanotubes having a plurality of organic functional units or moieties bonded generally in a covalent manner to the inner wall of the single-walled nanotubes. Functionalization of the single-walled metal oxide nanotubes is performed in a single-step during synthesis of the nanotubes. The organic functional units are found dispersed throughout the length of the inner wall and not sterically hindered or contained at only the mouth or ends of the single-walled metal oxide nanotubes.

A continuous flow mobility classifier provide the ability to perform two-dimensional separation in mass spectrometry. An ionization system is used to ionize a sample. A differential mobility analyzer (DMA) (e.g., a nano-radial DMA) is coupled to the ionization system and to a mass spectrometer. The nano-RDMA is configured to separate the ionized sample by mobility for subsequent mass analysis by the mass spectrometer.
