A material for removing a contaminant, the material including an adsorption material for adsorption of a contaminant and a decomposition material for decomposition of a contaminant, wherein the adsorption material and the decomposition material are complexed with each other, and a contaminant decomposition onset temperature of the decomposition material is equal to or lower than a contaminant desorption onset temperature of the adsorption material.

Embodiments described herein relate generally to filter assemblies that include filter elements with cross-channel flow having flat and/or folded arrangements for optimized functionality and performance. The filter assemblies may be formed (e.g., shaped, constructed, etc.) using a variety of shapes, angles, configurations, and materials to improve the filtration and cross-channel flow of fluid through the filter media. The filter media may implement a wide variety of patterns (e.g., repeating, origami, rounded, etc.), shapes (e.g., tetrahedral, rhombus, square), and construction (e.g., pleated, integrated, interdigitated, etc.).

A dry gas scrubber is disclosed. The dry gas scrubber is for treatment of an effluent stream and comprises: a chamber having an inlet for receiving the effluent stream, a cooler coupled with the inlet and configured to cool the effluent stream, and a resin chamber downstream of the cooler and configured to receive the effluent stream for treatment. In this way, the cooler is interposed between the process tool and the resin chamber and operates to cool the effluent stream prior to its being delivered to the resin chamber. Cooling the effluent stream in this way helps to improve the performance of the resin, even when the effluent stream is at an elevated temperature.

A diffusive air purifier includes an air permeable container containing a chemical sorbent or a sorbent precursor. The sorbent has a chemical composition selected to achieve removal of an air pollutant via a chemical reaction that renders the predetermined air pollutant immobile. A method of manufacturing the diffusive air purifier includes impregnating a porous solid with a solution of sorbent precursor and a binding agent and drying the porous solid. A method of purifying indoor air includes detecting a measured concentration of an airborne chemical in an enclosed location; selecting the diffusive air purifier to adsorb the airborne chemical; and placing the diffusive air purifier in the enclosed location. Air diffuses through the outer container and into the sorbent where the chemical to be removed is retained. Air, free of the target chemical, diffuses out of the container and the process repeats.

A multi-functional air purification filter includes: a breathable support layer; a mesh layer provided on the breathable support layer; and a filter layer provided on the mesh layer, wherein at least a portion of the multi-functional air purification filter has a plurality of bends, and the mesh layer includes a coating layer of at least one of a photocatalytic material, an adsorption material, or a sterilizing material.

A filter unit (100) includes a rigid filter block (1) that filters out a gas or particles from a gas mixture flowing through the filter unit (100). The filter block (1) has two end faces (Sf.a, Sf.e) and a shell surface (M). A housing including a pot (4) and a cover (2) surrounds the filter block (1). The pot (4) includes a base (4.1) and a tube (4.2). A gap (Sp) occurs between the tube (4.2) of the pot (4) and the shell surface (M) of the filter block (1). Between one end face (Sf.a) of the filter block (1) and the base (4.1) of the pot (4) there is a flat inner area (3.1) of a deformable damping layer (3). An outer area (3.2) of the damping layer (3) surrounds the inner area (3.1) in a circular ring form and is located in the gap (Sp).

An apparatus for a dry gas scrubber includes: a cooling chamber defined by a housing having an inlet for receiving an effluent stream for treatment by the dry gas scrubber, an outlet for providing the effluent stream for treatment by the dry gas scrubber, and at least one cooling plate within the chamber, the cooling plate being thermally coupled with the housing and configured to deviate a direction of flow of the effluent stream when flowing from the inlet to the outlet. In this way, the cooling chamber is interposed between the process tool and the resin chamber of the dry gas scrubber and operates to cool the effluent stream prior to its being delivered to the resin chamber. Cooling the effluent stream in this way helps to improve the performance of the resin, even when the effluent stream is at an elevated temperature.

A dust collector apparatus includes a housing, an airflow generation module and a filter. The housing has one side formed at least one intake vent-hole and another side formed of at least one exhaust vent-hole. An inner side of the housing has an airflow channel formed between the intake vent-hole and the exhaust vent-hole. The airflow generation module comprises an airflow drawing unit for drawing an airflow in order to form the airflow channel between the intake vent-hole and the exhaust vent-hole, a control module for controlling the airflow drawing unit, and a power module. The filter is detachably arranged at the intake end and used for filtering dust in the air sucked by the airflow drawing unit. The dust collector apparatus of the present invention allows the dust particles to be properly collected by the filter without secondary scattering, and guides the airflow to be exhausted smoothly.

An air purification system includes a conduit extending between an inlet and an outlet, each in fluid communication with an enclosed environment. Ambient air from the enclosed environment enters the conduit via the inlet and treated air exits the conduit and enters the enclosed environment via the outlet. The system further includes a fibrous filter disposed within the conduit and configured to treat the ambient air thereby generating the treated air, and a renewal unit disposed within the conduit and configured to renew the fibrous filter.

The present disclosure is related to surfaces having various topographical features and methods of making same. The disclosed features, created on various polycrystalline metallic substrates, may aid in effectively and rapidly reducing or eliminating detrimental effects of microbes. In some embodiments, the surface features may include channels and combinations of angular features such as ledges, ridges, and nodules, which may help adsorption of microbes to the surface, increase the surface chemical activity, and increase the effective surface area to support and/or accelerate the killing or deactivation of microbes. Some embodiments including reducing radii of curvature on channel ledges, intra-grain angular ridges, and angular nodules to accelerate disruption of microbial outer membranes by charge concentration and charge transfer. Also described are methods of producing the disclosed topographical surface features at low cost on various polycrystalline solid metal surfaces, for example cast, forged, rolled, drawn, wrought, deposited or coated.
