Inventors: Orban; Jon et al.AbstractCleaning systems and methods, wherein the system includes a chamber configured to receive a body part of a user or an object, where the user’s skin or object is exposed to one or more cleaning, disinfecting and/or sterilizing processes, such as chemical agents, mechanical energy, ultraviolet light, and ultrasound, to clean, disinfect and/or sterilize the skin or…

Editorial article in Food Safety Magazine studying the use of ultraviolet C radiation to create hydroxyl radicals to be employed as hatchery disinfection strategy superior to direct ultraviolet disfection.Excerpts:The contamination of hatchery eggs by Salmonella can result in Salmonella disseminating throughout a flock after hatching, establishing itself and leading to poultry meat contamination that can sicken consumers. The traditional egg disinfection…

Inventors: Bohácek; Štefan et al.AbstractA nanofiltration device for inactivating droplet-transmitted pathogens. The microdroplets are captured by filtering contaminated air on a filter material/paper with the nanofibrillated cellulose and/or nanocellulose surface treatment containing antiseptic metal ions and an adjuvant in the retained residual water. The air is sucked into the openings of the nanofiltration device located…

Article in ABC News Australia about efforts of wine grape growers to control costs of disease by using robots that irradiate plants with germicidal ultraviolet light (UVC).Excerpts:Wine grape growers grappling with declining sales and rising expenses hope advancements in autonomous technology can help to safeguard the industry.Global wine consumption has dropped considerably over the last…

Inventors: Bonutti; Peter M. et al.AbstractA disinfecting system includes a housing. An ultraviolet light (UV) source is secured to the housing and configured to emit UV light for disinfection of a target. A processor is secured to the housing in communication with the UV light source. The processor is configured to activate the UV light source for a selected amount of time suitable for disinfection of the target.Tags/Keywords: ultraviolet,…
