Process for the preparation of precipitated silicas, precipitated silicas and their uses, in particular for the reinforcement of polymers
The invention relates to a process for the preparation of a novel precipitated silica, wherein: a silicate is reacted with an acidifying agent, so as to obtain a silica suspension; said silica suspension is filtered, so as to obtain a filter cake; said filter cake is subjected to a liquefaction operation, optionally in the presence of an aluminium compound; wherein at least one polycarboxylic acid is added to the filter cake, during or after the liquefaction operation. It also relates to a novel precipitated silica and to its uses.

ELECTRICAL GROUNDING ASSEMBLY
An electrical grounding assembly includes an electrically conductive metal grounding substrate that is electrically connectable to a structure to be electrically grounded. A corrosion-protective jacket is on the grounding substrate. The jacket is electrically conductive and water impermeable, and includes a polymeric matrix and a particulate carbonaceous material dispersed in the polymeric matrix.

Process for manufacturing a component for an emissions treatment unit
In a process for manufacturing a component for an emissions treatment unit, green ceramic product is extruded through a die to form an extrusion having a honeycomb substrate structure with an array of parallel, linear tubular cells extending along its length, the cells bounded by walls dividing adjacent cells from one another. A ceramic unit is obtained by cutting off, curing and firing a length of the extrusion a length of the extrusion. Following the firing, a mixture of a flowable, uncured curable material and a particulate metal component is injected from an end of the ceramic unit into selected ones of the cells so as to block the selected cells over at least a part of their lengths while maintaining all of the walls of the ceramic unit. The injected mixture is then cured to render it solid.
