Engineers have created a deep-ultraviolet (UV) laser using semiconductor materials that show great promise for improving the use of UV light for sterilizing medical tools, among other applications. The aluminum gallium nitride-based device is capable of emitting a deep-UV laser at sought-after wavelengths and modal line widths. The team used molecular beam epitaxy, a crystal growth technique, to grow a high-quality crystal of aluminum nitride
Hydrogen peroxide has made headlines as researchers and medical centers around the country have been testing its viability in decontaminating N95 masks to deal with shortages amid the COVID-19 pandemic. While results so far are promising, some researchers worry that the chemical’s poor shelf life could make such decontamination efforts costly
Tier-1 supplier Magna evaluates its proven Puro virus-killing technology for a potentially new role: sanitizing vehicle interiors. An ozone-generating process that kills germs is being evaluated by supplier Magna for potential use in vehicle cabins, as the mobility industry seeks sustainable solutions for protecting passenger health. Magna's Puro branded product, soon to enter volume production, is a portable, plastic container that sanitizes clothing, toys, stuffed animals or other items placed inside a latched and locked bin. “Our immediate focus for our sanitizing technology is to help with the current personal protection equipment (PPE) shortage being experienced by our front-line coronavirus workers. That said, we hope to leverage this Magna technology to sanitize ride sharing vehicles and other future mobility applications,” Scott Mitchell, global director of New Technology & Innovation for Magna Mechatronics, told SAE's Autonomous Vehicle Engineering
Privately-owned vehicles were never so safe as they are today. Nor have they made so much sense. That thought hit me between the nostrils recently, as I sprayed a pungent disinfectant on the steering wheel of my family's B-segment runabout. Carefully wiping down the car's touch points with antibacterial cleaners has become a new pandemic ritual for us after returning home from food shopping and other essential missions. My little tribe generally keeps the interiors of our two vehicles tidy. Finding the occasional French fry buried in a seat track is, however, preferable to the dangerous microbes deposited every minute in the typical bus, train, or ride-share. The term “clean,” as understood by transit passengers, means a few spritzes by a custodial crew racing to meet uptime targets
Among all of the large-scale disinfection and/or decontamination technologies available, vaporized hydrogen peroxide (VHP®) is of particular interest due to its rapid sterilization, easy usage, intrinsic environmental friendliness (i.e. simple by-products composed of only water and oxygen), and compatibility with many materials and systems
Spinoff is NASA's annual publication featuring successfully commercialized NASA technology. This commercialization has contributed to the development of products and services in the fields of health and medicine, consumer goods, transportation, public safety, computer technology, and environmental resources
This specification covers disinfectants or chemicals for use in disinfecting aircraft after carrying livestock
When validating the steam sterilization instructions for a reusable medical device, first-time pass rates are important to manufacturers. Failures in validation testing require resolution, adding to the total validation time, which can result in a delay to a regulatory submission, getting a device to market, or both

Problems associated with, and new strategies for, inactivating resistant organisms like Bacillus canaveralius (found at Kennedy Space Center during a survey of three NASA cleanrooms) have been defined. Identifying the particular component of the spore that allows its heightened resistance can guide the development of sterilization procedures that are targeted to the specific molecules responsible for resistance, while avoiding using unduly harsh methods that jeopardize equipment
