An extrusion system () according to certain aspects includes at least one infrared emitting device () arranged in a generally cylindrical shape with a hollow interior. The at least one infrared emitting device () is positioned downstream of an outlet of an extrusion die () to irradiate a perimeter of wet extrudate material in a uniform manner to form stiffened wet extrudate material () before such material is received by an extrudate support channel (). The at least one infrared emitting device () generally uniformly stiffens the skin of the wet extrudate material () to resist mechanical deformation of the extrudate material during subsequent handling steps. Such skin stiffening allows for increased tolerance of handling forces and permits extrusion of softer wet extrudate material without compromising the shape of a fired ceramic product.

Disclosed are cement compositions for applying to honeycomb bodies as a plugging cement composition, segment cement, or even as an after-applied artificial skin or coating. The cement compositions generally comprise an inorganic powder batch mixture; an organic binder; a liquid vehicle; and a gelled inorganic binder. Also disclosed are honeycomb bodies having the disclosed cement compositions applied thereto, and methods for making same.

Sorbent substrates for COcapture and methods for forming the same are disclosed. In one embodiment, a method for forming a sorbent substrate for COcapture may include forming a plurality of matrix rods from a sorbent material and forming a plurality of channel rods from a support material. The plurality of matrix rods may then be co-extruded with the plurality of channel rods to form a plurality of sorbent filaments comprising a matrix of the sorbent material in which channels of support material are positioned such that the channels extend in an axial direction of each of the plurality of sorbent filaments. The plurality of sorbent filaments may then be stacked to form a filament assembly in which the plurality of sorbent filaments are axially aligned. Thereafter, the plurality of sorbent filaments of the filament assembly may be bonded to one another to form the sorbent substrate.

A magnetic photonic crystal for providing asymmetry of spatial frequencies in the propagation of light is provided. The crystal is formed from at least two materials having different indices of refraction which are aligned along the longitudinal axis of the crystal. And arranged in an array whose symmetry does not include a spatial inversion operator such that (x,y)==/=(&#x2212;x,&#x2212;y). One or more of the materials forming the array is magnetic such that the magnetic group representation of the array does not include time inversion as a symmetric operator. In operation, when the magnetic material forming the material is magnetized, the group velocity property of light propagated in one direction along the axis of the array is different from the group velocity property of light transmitted in an opposite direction through the array. The magnetic photonic crystal may be used, for example, as an optical memory device or a high speed modulator/demodulator.
