Abstract: A method for manufacturing filtered high aspect ratio silver nanowires is provided, wherein a total glycol concentration is <0.001 wt % at all times.

Abstract: Acicular mullite bodies are made in two-step firing process in which a green body is converted first to a fluorotopaz and then to acicular mullite. The bodies are contained within an enclosed region of the furnace. A flow of process gas is provided through the enclosed region during the fluorotopaz-forming step. The process gas is introduced into the enclosed region through multiple openings on at least one side of the enclosed region, and withdrawn through multiple openings on another side of the enclosed region. During the acicular mullite-forming step, a flow of purge gas is maintained in the exterior portion of the furnace. This purge gas may be removed by flowing it into the enclosed region of the furnace and out of the furnace from the enclosed region without re-entering the exterior portion for the furnace.

Abstract: An improved ceramic honeycomb structure is comprised of at least two separate smaller ceramic honeycombs that have been adhered together by a cement layer comprised of a cement layer has at least two regions of differing porosity or cement layer where the ratio of toughness/Young's modulus is at least about 0.1 MPa·m1/2/GPa.

Abstract: Contacting a mixture of two or more porogens with a mixture used to prepare a ceramic body; wherein one of the porogens has a significantly different chemical property from that of at least one of the other porogens. The ceramic material is dried, and calcinated. The ceramic material must withstand the heat from the drying process and the calcining to become a sintered: (ceramic) body. By increasing the overall stability of the ceramic material the product yield is about 90% or greater.

Abstract: A ceramic plugging paste useful to make plugs having through holes (partial plugs) in a ceramic honeycomb filter in which the plugging paste is comprised of a ceramic particulate and fluid carrier, wherein the ceramic particulate has at least 90% by number of the particulates being less than 50 micrometers and the fluid carrier is present in an amount sufficient such that the plugging paste is fluid enough to be inserted into a ceramic honeycomb channel and be retained in said channel without any other support other than the walls of the honeycomb defining the channel. Such a paste may be easily injected in the same manner as regular pastes. Such pastes and methods advantageously realize plugs having a through hole resulting in honeycomb filters having low pressure drop while still retaining effective particulate filtration.

Abstract: The invention is a process for making high molecular weight polymers of monoalkenyl arene monomers comprising:1) copolymerizing vinylbenzocyclobutene with the monoalkenyl arene monomer through the vinyl moiety;2) submitting the thus formed copolymer to conditions sufficient to open the side rings of the benzocyclobutene moieties;wherein the amount of vinylbenzocyclobutene in the copolymer is such that the polymer formed by step 2) does not reach a gel point. Such copolymers allow the building of molecular weight after the initial polymerization.
