We describe methods and materials for inhibiting the growth of a microbial pathogen of a plant. The method comprises the steps of applying to the plant a combination of a dye-bearing compound which is a reactive oxygen species photosensitizer; and a copper compound, which increases the microbial lethality of the dye-bearing compound towards the microbial pathogen; and exposing the plant to light to activate the combination of the dye-bearing compound and the copper compound and inhibiting growth of a microbial pathogen of a plant. The combination of the dye-bearing compound and the copper compound may result in a synergistic ability to reduce the growth of a plant pathogen.

A composition that can decontaminate opioids on surfaces or objects, and in particular decontaminate fentanyls on surfaces using an opioid-active reagent and an opioid-effective solubilizing agent, which is a mixture of an alkyl dimethylamine oxide surfactant, an alkyl dimethylamine oxide surfactant, a Calkyl polyethylene glycol sorbitan fatty ester surfactant, and a Csecondary alcohol ethoxylate surfactant. Preferably, the opioid-active reagent is chlorine dioxide. Additionally, methods for decontaminating opioids on surfaces using this composition.

The present invention provides a humidity tolerant COgenerator that operates in combination with an arthropod trap. The COgenerator comprises a means for controllably adding solid pellets to an aqueous acid solution, and optionally includes a sound-based counting system for counting the number of pellets dispensed from a feeder reservoir and into a reaction chamber. The invention also provides a method of using the same.

The present invention relates to a method for treating plant pests or pathogens. The disclosed method of protecting plants against pests includes a plant protection composition, wherein the plant protection composition comprises a water-soluble activator and a benefit active precursor. The composition is applied externally to the plant where a benefit active species is generated in situ, thus mitigating the pest.

Methods for plant protection

The present invention provides a method for determining the functionality remaining in a functional fabric, the method comprising the steps of: providing a used functional fabric having a known original functionality, a current wear, and a current unknown functionality, providing a light source, providing a detector, optically measuring the current wear using the light source and the detector, and evaluating the current unknown functionality using a correlation that expresses the current unknown functionality as a function of the current wear, optionally the detector further comprises a digital camera, and wherein the method further comprises the step of: obtaining a magnified image of the functional fabric and quantifying the fractal dimension using a box-method fractal analysis on the image. The method may be applied the insecticide treated fabrics.

Non-destructive evaluation of functional fabrics

A polymer is prepared by polymerizing a polymerizable component from a mixture containing the polymerizable component and a surfactant, the surfactant and the polymerizable component being present in the mixture in a molar ratio of at least 0.2:1, having an average pore size greater than 4 nm and a density greater than 0.1 g/cc. The polymerizable component can comprise a resorcinol/formaldehyde system and the mixture can comprise an aqueous solution or the polymerizable component can comprise a divinylbenzene/styrene system and the mixture can comprise an organic solution. Alternatively, the polymerizable component can comprise vinylidene chloride or a vinylidene chloride/divinylbenzene system. The polymer may be monolithic, have a BET surface area of at least about 50 m /g., include a quantity of at least one metal powder, or have an electrical conductivity greater than 10 Scm .

Mesoporous carbons and polymers

A mesoporous material prepared by polymerizing a resorcinol/formaldehyde system from an aqueous solution containing resorcinol, formaldehyde and a surfactant and optionally pyrolyzing the polymer to form a primarily carbonaceous solid. The material has an average pore size between 4 and 75 nm and is suitable for use in liquid-phase surface limited applications, including sorbent, catalytic, and electrical applications.

Improved heaters and self-heating packages that function without application of external energy. Heat is generated by contact of a heat-producing composition, such as calcium oxide, and an activating solution which is typically water. The heater contains multi-compartments containing heat-producing composition and activating solution. The heater is activated by application of hand pressure to rupture a frangible seal which allows the heater components to mix. The heater compartments are at least in part formed from flexible walls. The self-heating package has one or more products or product containers in thermal contact with one or more heaters. In preferred packaging embodiments, the heating package has one or more product containers or pouches in thermal contact with one or more heaters. In a specific embodiment, the product container is integrally formed with the heater. Preferred self-heating packages are constructed entirely of flexible packaging materials.

A portable heat source that may be used to warm food, beverage or other supplies. The heater contains a heat-producing composition that is a solid that may be stored for long periods of time, and activated by addition of water or an aqueous solution. Heat-producing compositions contain an acidic anhydride, an acidic salt, a basic anhydride or a basic salt. Preferred heat-producing compositions contain a mixture of an acidic anhydride or salt together with a basic anhydride or salt, such that addition of water to both acidic and basic anhydrides produces heat as well as acid and base respectively; subsequent reaction of the acid and base produces additional heat, as well as a safe, neutral product that is easily disposed. The invention further consists of means and methods for regulating the rate of heat production in heaters by the addition of inert additives to heat-producing compositions and the application of processing methods that regulate access of water to heat-producing compounds. Addition of inert materials and shaping, agglomerating, pelleting and like processing of heat-producing materials are applied to produced heat at a rate compatible with the rate at which the food or other materials can absorb the heat. The invention further consists of devices incorporating the materials to be heated in an advantageous arrangement with the heater composition.

A plurality of temperature conditioning units are divided into groups with the groups being sequentially and repetitively, one after the other, enabled for a first preset number of timing intervals and then disabled for a second preset number of timing intervals. The sum of the first and second preset number of timing intervals is equal to the total number of groups so that at any given time, but on a rotating basis, the first preset number of groups of units is enabled and the second preset number is disabled. A setback feature which can be overriden by a thermostatic control is provided for off hours. An alarm system provides warning of abnormal operation of any one of the units as detected by excessive cycling.
