Extracting Constituent Molecules from Blood or Other Liquids
Excess water can be removed from blood by passing the blood through channels that are surrounded by nanotubes with spaces therebetween. Each channel is wide enough for blood to flow through, and the nanotubes are spaced close enough to each other to retain the blood within the channels. Gas passing through the spaces between the nanotubes outside the channels comes into contact with the blood at the outer boundaries of the channels, and the excess water in the blood evaporates into the gas. In other embodiments, an undesirable molecule (e.g., ammonia) can be removed from blood by passing the blood through channels that are surrounded by nanotubes with spaces therebetween. Gas passing through the spaces between the nanotubes outside the channels comes into contact with the blood at the outer boundaries of the channels, and the undesirable molecule in the blood diffuses into the gas.

METHOD FOR HYDROPHILIZING POROUS MEMBRANE AND METHOD FOR MANUFACTURING ION-EXCHANGE MEMBRANE USING SAME
In one exemplary embodiment of the present invention, there are provided a method of hydrophilizing a porous membrane which includes treating a porous membrane with plasma in the presence of a mixed gas containing sulfur dioxide (SO.sub.2) and oxygen (O.sub.2), and a method of preparing an ion-exchange membrane using the same.
Membrane Device for Water and Energy Exchange
A device for exchange of water molecule and temperature between two fluids. The device comprises thin molecular sieve membrane sheets that allow water molecules to permeate through while blocking cross-over of the exchanging fluids. The device provides two sets of flow channels having a hydraulic diameter ranged from 0.5 to 2.0 mm for respective process and sweep fluid flows. The two sets of the channels are separated by a membrane sheet having a thickness less than 200 m. The thin molecule sieve membrane may be prepared by forming an ultra-thin zeolite membrane layer on a porous metal-based support sheet which provides very high water permeance so that the exchange can be conducted in a compact membrane module at high throughput. The device can be used to remove water from a process stream of higher water content by use of a sweep fluid of lower water content or higher water affinity. For example, the device can be used to condition outdoor fresh air close to the temperature and humidity of indoor air by conducting humidity and heat exchange between the fresh air flow drawn from outdoors and waste air discharged indoors.
