A process and an apparatus for refining molten glass. The apparatus includes a porous body having an inlet, an outlet, and a plurality of pores through which molten glass can flow between the inlet and the outlet. The plurality of pores are defined by walls having wall surfaces that are configured to interact with the molten glass as the molten glass flows between the inlet and the outlet to help refine the molten glass.

A foam ink composition for printing porous structures comprises stabilizing particles and gas bubbles dispersed in a solvent. The stabilizing particles comprise a predetermined interfacial energy so as to exhibit a contact angle with the solvent of from about 15 to about 90. At least a portion of the stabilizing particles are positioned at interfacial regions between the solvent and the gas bubbles, thereby stabilizing the gas bubbles in the foam ink composition. A 3D printed hierarchical porous structure comprises one or more continuous filaments arranged in a predetermined pattern on a substrate, the one or more continuous filaments comprising a sintered material and including a porosity of at least about 40 vol. %.

A method is provided to fabricate a green desiccant wheel. A green recycled adsorbent material of aluminum hydroxide and alumina is extracted and used as a base material to be added to a 3-dimensional (3D) network skeleton of a foam support. Through sintering, surface is hardened with the material adsorbed to megapores uniformly distributed. Thus, an adsorbent material of porous ceramic having pores on surface is made. The area contacting with moist air is increased. The moisture-adsorbing capacity is improved. At last, the whole procedure is integrated to develop a high-efficiency green desiccant wheel. Thus, the reusable materials are kept at innate grade or upgraded for recycling and regenerating. New materials and products can be further fabricated. The present invention helps solving environmental problem of wastes. Life cycle of resource is lengthened. A sample of recycling economy is innovated. Industrial efficiency is effectively enhanced.
