    摘要： An integrated filter for removing impurities from a fluid stream. The filter includes a first element adapted to remove at least some of the impurities by physical adsorption, and a second element adapted to remove at least some of the impurities by electrokinetic adsorption. Either or both of the first element and the second element further may be adapted to remove at least some of the impurities by sieving. The first element generally may be composed of loose particles or granules, or the first element may be composed of a porous block of an adsorbent, wherein the block is permeable to fluids and has interconnected pores therethrough. The second element generally is composed of a porous, charge-modified fibrous web which includes fibers prepared from a thermoplastic polymer. For example, the thermoplastic polymer may be a polyolefin. As another example, the porous, charge-modified fibrous web may be a nonwoven web, such as a meltblown or microfiber glass web. Alternatively, both the first and second elements may be in the form of a sheet.

    摘要： A method of fabricating nanoscale structural materials via the spontaneous organization of self-assembling proteins and the self-assembling proteins themselves. In a preferred embodiment of the invention, the self-assembling proteins included at least one occurrence of the following recognition sequence: ##STR1## wherein Xaa is a charged residue selected from the group consisting of Glu, Lys, Arg and Asp, and the method comprises admixing proteins which include species of the aforementioned recognition sequence which are prone to dimerization, whereby the admixed proteins are caused to spontaneously organize into nanoscale structural materials via their respective recognition sequences.

    摘要： Positive electrode-active materials for use in lithium-ion and lithium-ion polymer batteries contain quaternary composite oxides of manganese, nickel, cobalt and aluminum where one of the four is present at levels of over 70 mol percent. The composite oxides can be lithiated to form positive electrode-active materials that are stable over at least ten charge/discharge cycles at voltage levels over 4.8 volts, and have capacities of over 200 mAh/g. Methods for producing the materials and electrochemical cells and batteries that include the materials are also provided.
