Abstract: A method for suppressing the formation of ammonia comprising providing a carrier material to a container having a headspace; providing a bacteria and an odor inhibitor to the carrier material, the bacteria comprising Staphylococcus-xylosus and/or Staphylococcus-cohnii bacteria, and the odor inhibitor comprising an aminopolycarboxylic acid compound and a polyprotic acid compound, wherein at least one of the aminopolycarboxylic acid compound or the polyprotic acid compound is the salt form of the acid; and applying animal waste to the carrier material; wherein there is a 5 to 98 percent improvement of ammonia content in the headspace as compared to an untreated control comprising a container containing the carrier material and the bacteria and not contain the odor inhibitor. An ammonia suppressing composition.

Abstract: An odor control agent comprising: a filler; a binder; an active comprising an aminopolycarboxylic acid and a polyprotic acid. An odor control agent comprising: an active comprising an aminopolycarboxylic acid and a polyprotic acid, wherein at least one of the aminopolycarboxylic acid or the polyprotic acid is the salt form of the acid.

Abstract: A method including providing an aqueous mixture containing a sulfonated aromatic polymer component and applying the aqueous mixture to an aggregation of particulates sufficient to increase the water holding capacity of the aggregation of particulates.

Abstract: Provided herein are paper-based microfluidic devices that can be configured to induce fast fluid flow through a hollow microfluidic channel under low applied pressure. The microfluidic devices can comprise a fluid inlet, a fluid outlet, and a hollow channel fluidly connecting the fluid inlet and the fluid outlet, so as to form a fluid flow path from the fluid inlet to the fluid outlet. The hollow channel can comprise a fluid flow path defined by a floor, two or more side walls, and optionally a ceiling. One or more of the interior surfaces of the hollow channel can comprise a hydrophilic material. The hydrophilic material can drive fluid flow through the hollow channel, allowing for fast fluid flow through the hollow microfluidic channel under low applied pressure. The devices are well suited for use in numerous sensing applications, for example, quantitative, low limit-of-detection, and/or point-of-care paper analytical devices.
