Abstract: An encapsulated fiber composition (typically resulting from an electrospinning process) containing: (i) a lengthwise core portion of the fiber comprising an amine-containing material for adsorbing carbon dioxide; and (ii) a lengthwise sheath portion of the fiber surrounding said lengthwise core portion, wherein the lengthwise sheath portion comprises a microporous polymer. Particularly described are fiber compositions containing a nanoparticle organic hybrid material (NOHM) or organoamine or amine-containing sorbent (e.g., PEI or TEPA) in a core portion of the fiber and a polymer of intrinsic microporosity (PIM), such as PIM-1 or PIM-2, or PAN or PAN combined with a polysilazane or polysiloxane in a sheath portion of the fiber. A method of using the fiber composition to capture carbon dioxide, such as from ambient air, is also described.

Abstract: Air filters formed from mats of protein-containing nanowires are provided. The nanowires are formed into a mat with pores that allow air to pass through while physically filtering particulate matter. The protein in the protein-containing nanowires also serves to chemically filter polluted air passed through the filter. Specifically, chemical functional groups from the many amino acids that comprise the protein of the protein-containing nanowire react with certain chemical pollutants (e.g., carbon monoxide and formaldehyde) in order to capture or otherwise neutralize the pollutant. Accordingly, the single nanofiber mat performs two filtering functions. Methods of filtering air using the provided air filters are also disclosed, as well as methods for making the air filters from protein-containing nanofibers.

Abstract: The present invention provides a porous material which has continuous pores and comprises a polymethyl methacrylate as a main component, wherein the continuous pores have a diameter of 0.001 μm to 500 μm and at least one surface of the porous material has a porosity of 10% to 80%; a separation membrane composed of the same; an adsorbent composed of the same; and a method production of the same. A porous material whose surface porosity and pore diameter are each controlled in a specific range can be obtained. The porous material has a fine and uniform porous structure in which the pore diameter can be controlled in the order of nanometers to micrometers; therefore, it can be advantageously used as a separation membrane such as a blood component separation membrane of an artificial kidney or the like or as an adsorbent.
