A system for decontaminating/neutralizing breathable air and surfaces in an occupied enclosed space, i.e. building, aircraft, vehicle or greenhouse, includes mounting an atmospheric hydroxyl radical generator along an inside surface of the atmospheric hydroxyl radical generator having respective opposite air inlets and air outlets. The hydroxyl radical generator includes a polygonal housing supporting a plurality of spaced crystal-spliced UV optics, which are tubular, medical grade pure quartz optics to emit/irradiate ultraviolet in the nanometer wavelength/ultraviolet spectrum of between 100 and 400 nanometers for deactivating and neutralizing atmospheric chemicals and pathogens in breathable air and surfaces. The hydroxyl radicals contact the walls of the reaction chamber housing. The hydroxyl radicals become created and excited to react quickly with impurities including VOC, virus, bacteria and fungi, rendering them inactivated and neutral. The breathable air passes through the polygonal housing and is decontaminated and neutralized of impurities before entering the occupied enclosed space.

The disclosure herein concerns a method including receiving at a computer at least one target value of a scent parameter for an environment that is remote from the computer, receiving at the computer a sensed parameter of the environment, and controlling, via the computer, diffusion of a liquid from a source of the liquid in fluid communication with at least one scent diffusion device to achieve the target value of the scent parameter, wherein controlling includes setting or adjusting an operation parameter of the at least one scent diffusion device in response to the sensed parameter.

An air sterilization device includes a reflector, a first LED light source, and a second LED light source. The reflector may include a body part having a circular column shape having a vacant space therein and having openings formed in upper and lower surfaces thereof, a first rotary body connected to a lower surface of the body part and shaped to have a vacant space therein, and a second rotary body connected to an upper surface of the body part and shaped to have a vacant space; a first LED light source may emit UV-C rays in a direction from the first rotary body to the body part; and a second LED light source may emit UV-C rays in a direction from the second rotary body to the body part, and the reflector may reflect the light emitted from the first LED light source and the light emitted from the second LED light source.

Articles can be provided with odor resistance by applying a dispersion of a halogenated heterocyclic N-halamine in an inert liquid carrier onto the surface of the article and allowing the inert liquid carrier to penetrate into it. The N-halamine accordingly becomes deposited on the surface of the article after the inert liquid carrier penetrates into the article. This method can be used to provide odor resistance to a variety of substrates, including garbage bags. It can also be used to deposit other functional particulates onto the surface of substrates having sufficient porosity to take up the vehicle. For instance, such functional particles can be oxidants that display antimicrobial and/or enzyme inhibitory efficacy or particles having toxin interaction potentials through oxidative degradation or adsorption of toxic substances in air and/or water, such as fluoride uptake by metal oxide microparticles.

A method, system, and apparatus of sterilizing or disinfecting a space or surface with UV light from a laser that produces UV or other light energy with germicidal effect, at least like UVGI. The light can be controlled in terms of power to be effective for germicidal effect on a given biological organism or agent. In cases where humans might be present and represent a risk of interaction with the laser, techniques are used to remove those risks. The laser can be directed to a single relatively small area, aimed to multiple areas, or scanned to cover larger areas. It allows either human operation at stand-off distances from the relevant spaces, volumes, areas, surfaces (e.g., at least inches and typically feet or tens of feet). It has an indefinite useful operation life.

Methods and devices for formulating scented nanoemulsions and dispersing one or more scents is disclosed. In some embodiments, the method includes providing a first mixture including water and a water surfactant, providing a second mixture including a fragrance material and an fragrance surfactant, mixing the first and second mixtures to create a temporary emulsion, and performing one or more high-energy homogenizations to the temporary emulsion until one or more desired physical properties of a resulting nanoemulsion are obtained. In some embodiments, the one or more high-energy homogenizations includes microfludization, sonication, and high-shear mixing. In some embodiments, the resulting nanoemulsion may thereafter be dispersed as a scent via an aerosolizing device. In some embodiments, the aerosolizing device may disburse scents in response to actions and/or events experienced in an AV/AR system.
