The possibility to consolidate alumina powder stabilized Pickering emulsions of paraffin oil in ethanol by means of electrophoretic deposition (EPD) into freestanding porous objects is reported. The pore forming paraffin is extracted from the consolidated powder compact by means of evaporation prior to sintering. The sintered ceramics contain spherical pores with a diameter that can be tuned from 200 m to 20 m. Both open and closed porosities can be obtained by altering the emulsion composition. Since no pore forming fugitive solid organic binder is used, the delicate and time-consuming debinding step during processing is eliminated.

## Abstract We report the results of the experimental study of the preparation of hybrid porous polymer material carrying gold nanorods (NRs) on the surface of pores. The material was prepared by utilizing two effects occurring concurrently: the photoinitiated polymerizationβinduced phase separatio
Interconnected piezoelectric porous ceramics PZT have been tested for possible use in hydrophone applications. These materials consisted of: (1) ceramics with fine porosity having pores from 50 to 100 m and (2) cellular ceramics having cavities of the order of the millimeters. Porous ceramics are c
