    Abstract: The compositions and methods disclosed relate to the removal of a metal from a medium, such as an aqueous medium. The aqueous medium may be, for example, wastewater, such as wastewater from the microelectronics industry. Blended compositions were discovered to be synergistically favorable for lowered toxicity and increased coagulating ability in the chemical precipitation of metal contaminants. Compositions may include, for example, polymeric DTC and TMT. Target metals may include, for example, heavy metals, such as copper, nickel, and mercury.

    Abstract: The present disclosure provides methods for cleaning industrial equipment. In one example, a method for reducing microorganism from industrial equipment includes: (1) cleaning the equipment with one or more CIP compositions using a CIP process; (2) rinsing the equipment with water; (3) adding an enzyme composition into the CIP process; (4) analyzing a sample of the fluid within the CIP process before, after, or before and after the addition of the enzyme composition to detect microorganisms; and (5) modifying the CIP process in response to any detected microorganism.

    Abstract: Compounds, compositions and methods are provided as surfactants, fabric softening agents, corrosion inhibitors, bio-film inhibitors, biocides, and rheology modifiers. The multi-ionic surfactants are compounds having a structure corresponding to Formula 1, or a salt thereof: Wherein R1 is C1-C10 alkylene; R2 is independently hydrogen, —(CH2)x—NR20R21, or —(CH2)x—C(R10)—C(O)—X—Z; R3 and R4 are independently hydrogen, —(CH2)x—C(R10)—C(O)—X—Z, or R3 and R4 together with the nitrogen they are attached to form a substituted nitrogen-containing heterocyclyl; R5 and R6 are independently hydrogen, —(CH2)x—C(R10)—C(O)—X—Z, or R5 and R6 together with the nitrogen they are attached to form a substituted nitrogen-containing heterocyclyl; R10 is hydrogen, alkyl, aryl, or alkaryl; R11, R12, and R13 are independently C1 to C1 alkyl or alkaryl; R20 and R21 are independently hydrogen, —(CH2)x—NR20R21, —(CH2)x—C(R10)—C(O)—X—Z, or together with the nitrogen they are attached to form a substituted nitrogen-containing heterocyclyl; X is NH or O; Z is hydrogen, L1-NR11R12R13, L2-PR11R12R13, L3-COOH, L4-SO3H, L5-PO3H, or a salt thereof; L1, L2, L3, L4, and L5 are independently C1-C1 alkylene or alkenylene; n is an integer of 1 to 10; and x is an integer of 1 to 10; wherein at least one of R3 and R4, or R5 and R6 together form a substituted nitrogen-containing heterocyclyl; and wherein at least one R2 is —(CH2)x—C(R10)—C(O)—X—Z or —(CH2)x—NR20R21 wherein one of R20 or R21 is —(CH2)x—C(R10)—C(O)—X—Z.

    Abstract: An automated cleaning machine includes a trained cleaning outcome classifier that automatically classifies or scores cleaning outcomes for a cleaning machine using machine learning techniques. The cleaning outcome classifier may be trained on training data comprising a plurality of training inputs and a known output for each of the plurality of training inputs. Each of the plurality of training inputs may include one or more cleaning process parameters corresponding to a cleaning process executed by a cleaning machine executed during a training phase. The known output for each training input may include a cleaning outcome classification or score. The cleaning outcome of a novel cleaning process may then be classified or scored with the trained cleaning outcome classifier based on one or more cleaning process parameters corresponding to the novel cleaning process.

    Abstract: Methods and compositions for improving a papermaking process are provided herein. The compositions include, for example, an oil, an emulsifying surfactant, and a formulation aid. The methods may include adding an effective amount of the composition to a foraminous surface and contacting the foraminous surface with a furnish. Water may be drained through the foraminous surface, thus forming a sheet on the foraminous surface, which may be transferred to a felt, a belt, a fabric, or elsewhere.
