摘要： A low-cost and easy-to-fabricate mixed e− and CO32− conducting membrane for advanced high-flux and selective electrochemical CO2 separation from flue gas is provided. The membrane includes a CO32−-conducting molten carbonate phase and an e−-conducting lithiated Ni-oxide interphase that can be formed in situ during operation. The membrane exhibits a CO2 flux density greater than 0.8 mL/(minute·cm2) at 850° C. with a selectivity ranging from about 100 to about 500 and excellent stability for up to about 450 hours. Further, the self-formed interphase Li0.4Ni1.6O2 is highly electron conducting and can provide electrons to the co-reduction of CO2 and O2 into CO32−. Such a membrane is an alternative to the conventional “size-sieving” inorganic and “dissolution-diffusion” organic counterparts for CO2 capture from flue gas.

摘要： The present invention provides an ultrafiltration membrane comprising a sulfone polymer membrane matrix with pores and an organic polymer sealing layer, wherein the pores are filled with nanoadsorbents. The present invention further provides a method for preparing the ultrafiltration membrane, which includes the following steps: (1) synthesizing nanoadsorbents; (2) preparing the sulfone polymer membrane matrix by immersion-precipitation phase inversion; and (3) immobilizing nanoadsorbents in the pores of the sulfone polymer membrane matrix by reverse filling, then sealing the pores with organic polymers to form a multifunctional ultrafiltration membrane. In the present invention, colloidal gold, polyethylene glycol molecules and Pb(II) ions (and so forth) are utilized as models of viruses, macromolecular organic pollutants, and small molecular pollutants, respectively. It is shown that the multifunctional ultrafiltration membrane allows for removal of multiple pollutants from water and can simultaneously remove multiple pollutants under low pressure.

摘要： A process for making an iron oxide impregnated carbon nanotube membrane. In this template-free and binder-free process, iron oxide nanoparticles are homogeneously dispersed onto the surface of carbon nanotubes by wet impregnation. The amount of iron oxide nanoparticles loaded on the carbon nanotubes range from 0.25-80% by weight per total weight of the doped carbon nanotubes. The iron oxide doped carbon nanotubes are then pressed to forma carbon nanotube disc which is then sintered at high temperatures to form a mixed matrix membrane of iron oxide nanoparticles homogeneously dispersed across a carbon nanotube matrix. Methods of characterizing porosity, hydrophilicity and fouling potential of the carbon nanotube membrane are also described.

摘要： A tunable nanofiber filter device can include a filter housing defining an interior space, the housing having defined therein and inlet and an outlet, each in fluid communication with the interior space, and a plurality of filter laminas disposed within the interior space, each filter lamina including an upper surface, a lower surface, and an aperture defined therethrough. The plurality of filter laminas can be arranged in a stack wherein the opposing surfaces of adjacent filter laminas define a portion of an interlaminar flow space extending between the opposing surfaces. The flow space can be in fluid communication with the apertures of corresponding adjacent filter laminas to form a continuous flow passage extending through the lamina stack from the inlet to the outlet. An array nanofibers can extend into the flow passage from a portion of each filter lamina such that a fluid flowed through the flow passage flows across a portion of said array.
