(EN) ABSTRACT TITLE OF INVENTION: STRUCTURED ELEMENTS AND METHODS OF USEStructured elements with capabilities for stream flow division and distribution andmitigation of undesired species that exceed those of conventionally available materials areprovided. The structured elements provide increased opportunities for surface attraction,retention and coalescence of undesired species in a process stream. The functional contactsurfaces of the structured elements can include one or more of the faces of cells, the surfacesof struts connecting cells, the surfaces of nodes connecting struts, and the surfaces ofasperities or irregularities caused by channels, flutes, spikes, fibrils or filaments in or on thematerial surfaces.[Figure 1] 2326
