Abstract: A method for separating carbon dioxide from flue gas to generate a high purity CO2 stream.

Abstract: The present application provides an air quality control system for cleaning a flue gas from a fluid catalytic cracking unit. The air quality control system may include a selective catalytic reduction system in communication with the flue gas to remove nitrogen oxides and a wet scrubber positioned downstream of the selective catalytic reduction system and in communication with the flue gas to remove sulfur oxides and particulates.

Abstract: The invention includes biostructures which may be characterized as having substantially all of the organic-solvent-soluble material in the form of a network of irregularly shaped perforated films. The biostructure may further include particles of a substantially-insoluble material, which may be a member of the calcium phosphate family. The biostructure may be osteoconductive. The biostructure may further contain an Active Pharmaceutical Ingredient or other bioactive substance. The API may be a substance which stimulates the production of bone morphogenetic protein, such as Lovastatin or related substances, thereby making the biostructure effectively osteoinductive. One or more of the polymers may have a resorption rate in the human body such as to control the release of the API. Methods of manufacture are also disclosed.

Abstract: The invention includes a method of three dimensional printing comprising manufacturing microbeads by an emulsion solvent extraction/evaporation process, followed by three dimensional printing onto powder layers comprising the microbeads. The invention also includes polymeric microbeads containing a bioactive substance or Active Pharmaceutical Ingredient, particularly a substance which stimulates the formation of bone, such as members of the statin family, or growth factors. The microbeads further may contain within themselves smaller particles such as particles of members of the calcium phosphate family, thereby being osteoconductive. The invention also includes aggregates of any of such microbeads together with any of various other types of suitably-sized particles, such as discrete particles of osteoconductive material or porogens. The invention also includes porous biostructures including macrochannels and having advantageous packing of osteoconductive particles.

Abstract: The present invention is directed to a biostructure comprising an osteoconductive member and an osteoinductive material. The osteoinductive material may be located within a cavity in the osteoconductive material. In one aspect of the invention the osteoinductive material is demineralized bone matrix and the osteoconductive member comprises tricalcium phosphate.
