A water treatment composition includes a water soluble film formed into a sealed pouch. The pouch contains a composite of a phosphate removing substance, a polymer flocculant, or an enzyme, or any combination. The phosphate removing substance, the polymer flocculant, and the enzyme are bound to each other within the composite. The pouch is added to a body of water. The pouch dissolves to release the compounds and treat the water.

Methods and systems are provided for an emissions aftertreatment device. In one example, the emissions aftertreatment device may include a catalyst and a high entropy oxygen storage material formed of at least five metal oxides in equal molar proportions. The at least five metal oxides includes one or more rare earth metals as well as other metals with similar chemical properties as the rare earth metals.

The invention relates to a cyclic method of producing a hydrogen rich and/or a carbon monoxide rich stream using different materials, a first solid material, a second solid material and a CO.sub.2 sorbent material. In a first step a first gas stream comprising steam and at least one reductant is brought in contact with the three materials resulting in a hydrogen rich outlet stream. In a second step, the captured CO.sub.2 from the first step is released and converted to CO to produce a CO rich outlet stream. The invention further relates to an installation for producing a hydrogen rich and/or carbon monoxide rich stream.

Methods for purifying biological macromolecules are provided. Aspects of the subject methods include contacting the biological macromolecule with an exemplary hydroxamate affinity tag to produce a tagged moiety followed by purification of the tagged moiety by immobilized metal affinity chromatography (IMAC). Also provided are kits comprising an exemplary subject hydroxamate affinity tag, an IMAC resin and a metal ion configured for loading onto the resin, wherein the metal ion is capable of binding to a compound containing the hydroxamate affinity tag.

The present invention discloses a synthesis method for a layered dimetal-based nano lanthanum material capable of synchronously locking phosphorus, removing algae, and reducing turbidity, and the use thereof, and belongs to the field of environmental functional materials. In the present invention, a synthesis method includes: synthesizing LDHs by means of a single-drop coprecipitation method; filtering out an obtained product, washing the product with distilled water and drying; then adding the product to an alcohol solution of a lanthanum salt at certain concentration, and stirring for reaction; precipitating lanthanum ions in situ by adjusting a pH value of the solution; filtering out the reaction precipitate, washing the precipitate with an alcohol, and drying the precipitate to obtain an LDH-based nano lanthanum material.
