Abstract: A method of making a porous structure configured for use in a particulate filter includes bonding a plurality of glass bubbles to one another, and breaching the plurality of glass bubbles. Voids within individual breached glass bubbles open into one another to form cavities that extend through the porous structure.

Abstract: The present disclosure is directed to an antimicrobial composite material, and more particularly to an antimicrobial composite material comprising particles having a metal or metal alloy core and a porous inorganic material shell, coatings including the antimicrobial composite material, and methods of making the same. In some embodiments, Cu—SiO2 core-shell particles are disclosed in which the Cu core provides antimicrobial activity and the porous SiO2 shell functions as a barrier for the Cu core, thus preventing the Cu core from being directly exposed to air or moisture.

Abstract: Porous structures are made from compositions that include hollow glass bodies and an inorganic powder. The inorganic powder may act as a rigid frame member, a crystallization agent, or both, which reduces the shrinkage of the porous structures during firing. The porous structures made therefrom have an open porosity of greater than 70% and reduced shrinkage of less than 10% compared to the green structures prior to firing. Methods for firing the green structures made from the compositions are also disclosed, the firing methods including reducing a temperature ramping rate of the green structures during a crystallization temperature range of the glass of the hollow bodies.
