A method for producing a crystalline film comprising zeolite and/or zeolite-like crystals on a porous substrate is described. The method has the steps of: providing a porous support; modifying at least a surface of the top-layer of said porous support by treatment with a composition having one or more cationic polymer(s); rendering at least the outer surface of said porous support hydrophobic by treatment with a composition having one or more hydrophobic agent(s); subjecting said treated porous support to a composition having zeolite and/or zeolite-like crystals thereby depositing and attaching zeolite and/or zeolite-like crystals on said treated porous support, and growing a crystalline film of zeolite and/or zeolite-like crystals on said treated porous support and calcination. Crystalline films find use in a variety of fields such as in the production of membranes, catalysts etc.

The present invention relates to a honeycomb catalytic converter including: a honeycomb structured body in which multiple through-holes are arranged longitudinally in parallel with one another with a partition wall therebetween; a noble metal supported on the honeycomb structured body; and an inlet-side end face and on outlet-side end face, wherein each partition wall includes a substrate portion in the form of an extrudate containing a ceria-zirconia complex oxide and alumina, and a coat layer formed on a surface of the substrate portion and containing the noble metal, and the inlet-side end face has a higher aperture ratio than the outlet-side end face.

A nanocomposite coating that in turn extract self-replenishing (or -healing), superlubricious carbon film directly from natural gas or hydrocarbon gas in mechanical systems. The coating deposits on sealing and sliding surfaces reducing friction and wear. The result is a reduction in inefficiency, machine breakdown, and adverse environmental impact.
