摘要: Embodiments of the present disclosure are directed to systems and methods for removing formaldehyde from indoor air. Some embodiments include flowing an indoor airflow over and/or through a solid supported amine filtering medium, such that, at least a portion of formaldehyde entrained in the indoor airflow is removed therefrom. Some other embodiments include systems having one or more fans for providing velocity to one and/or another airflows (e.g., airflows to/from a formaldehyde filter).

摘要: Amorphous aluminosilicates are disclosed, and these amorphous aluminosilicates are characterized by a unique combination of high surface area, low oil absorption, and a significant fraction of the total pore volume resulting from micropores. These amorphous aluminosilicates can be used in various paint and coating applications, with the resultant dried or solid film capable of removing VOC's from the surrounding air.

摘要: Systems, compositions, and methods for dewatering and/or increasing a mechanical strength of mine tailings. These systems, compositions, and methods may include combining mine tailings with wicking fibers to form a composite mine tailings mixture. The wicking fibers may provide a conduit for the removal of fluid from the composite mine tailings mixture. The composite mine tailings mixture further may include a binder that may decrease repulsive forces among fine particles that comprise the mine tailings and/or increase attractive forces among the fine particles, leading to a separation of the fine particles from at least a portion of the fluid contained within the composite mine tailings mixture. The composite mine tailings mixture may be placed in a storage or dewatering area as a composite mine tailings mixture deposit, which may include internal structure, such as layers of the composite mine tailings mixture and/or long-range orientation of the wicking fibers contained therein.
