A mould for manufacturing a packing member from a liquid ceramic composition. The mould including a first part and a second part, in which the first and/or second mould parts are resiliently deformable and the first part and/or the second part include a plurality of open mould cavities. The first and second parts are operable to engage to form closed mould cavities, and the mould is operable to be moved from an open position in which the first and second parts are partially spaced by the deformation of a mould part and in which position mould cavities are open, to a partially closed position by reducing the deformation of the mould part and in which position some of the mould cavities are closed, and then to a closed position by further reducing the deformation of the mould part and in which position the first and second parts are engaged such that the mould cavities are closed.

Structured elements with capabilities for stream flow division and distribution and mitigation of undesired species that exceed those of conventionally available materials are provided. The structured elements provide increased opportunities for surface attraction, retention and coalescence of undesired species in a process stream. The functional contact surfaces of the structured elements can include one or more of the faces of cells, the surfaces of struts connecting cells, the surfaces of nodes connecting struts, and the surfaces of asperities or irregularities caused by channels, flutes, spikes, fibrils or filaments in or on the material surfaces.
