Glass-based substrates are described herein that may be processed by methods including applying a cover article onto a glass-based substrate, submerging the glass-based substrate in an etchant, and maintaining the submersion of the glass-based substrate in the etchant. The glass-based substrate may include a covered surface portion and an exposed surface portion. At least a portion of the covered surface portion may be in direct contact with the cover article. The covered surface portion may not be in contact with the etchant and the exposed surface portion may be in direct contact with the etchant. The etchant may contact the exposed surface portion and the cover article fora time sufficient to etch the exposed surface portion. The cover article may provide a barrier between the etchant and the covered surface portion for the entirety of the submerging.

Methods for etching glass-based substrates

A method of manufacturing a particulate filter includes plugging at least some of the channels of a green cellular ceramic body on a first end with a green plugging material that includes a liquid vehicle to form a partially plugged green cellular ceramic body, firing the partially plugged green cellular ceramic body to form a partially plugged ceramic article, and plugging at least some of the channels on a second end of the partially plugged ceramic article with a plugging material that sets at a temperature of less than 1000&#xb0; C.

The invention provides a monolithic catalyst support for hydrogenation and hydrotreating and in particular for selective hydrogenation of pyrolysis gasoline. The monolithic catalyst includes (i) a multicellular monolith body, preferably having a honeycomb structure, most preferably a honeycomb structure made of cordierite, the honeycomb structure having an inlet end, an outlet end, and a multiplicity of mutually adjoining cells extending along the length of the body from the inlet end to the outlet end, the cells being separated from one another by porous walls, and, (ii) a coating consisting of theta alumina synthesized in situ on the multicellular monolith body. The in situ theta alumina is strongly bonded with the multicellular monolith body and comprises at least 50% by weight of the washcoat layer, and preferably greater than 90% by weight.
