Using the Power of Light: Preventing the Airborne Spread of Coronavirus and Influenza Virus

图片
  Over the past six years, we have been working on a very exciting new approach to killing drug-resistant bacteria – superbugs- , as well as airborne viruses such as influenza, using a unique type of ultra-violet light. We have always known that ultraviolet light can efficiently kill all microbes, but conventional germicidal ultraviolet light is hazardous to our health, causing skin cancer and cataracts. We have identified a particular wavelength of UV light that has the best of both worlds – it’s safe and it kills microbes – including superbugs. In brief, it is pure physics – 222 nm light is safe for us because it cannot even penetrate through the dead-cell layer on the surface of our skin or the tear layer on the surface of our eyes – but because bacteria and viruses are physically very small, 222 nm light does have enough penetration to efficiently kill them. Click here to know more information. Currently, the most effective and safest way to fight against COVID-19 is far uvc 22...

Ushio, Inc. puts new UV sterilization technology developed with Columbia University into practical use in the United States

  Ushio, Inc. is selling the Far UV sterilizer “Care222® i series” equipped with the UV sterilization technology “Care222®” developed with Columbia University in the United States. This product utilizes the excellent sterilizing power of ultraviolet rays in an environment where people are present, and can simultaneously sterilize “the surface of objects and air” within the irradiated range. It is used in many places such as medical sites and public facilities because it is easy to sterilize with a single switch. Three advantages of introducing “Care222® i series” (1) Reduce time-consuming sterilization work with a single switch It takes a lot of effort to disinfect the equipment and places shared by users. The burden of such sterilization work is reduced with a single switch. (2) Simultaneous sterilization of objects and air within the range irradiated by ultraviolet rays Since it irradiates only ultraviolet rays that do not adversely affect the human body, it disinfects equipment...

Reduction of Patulin in Apple Juice Products by UV Light of Different Wavelengths in the UVC Range

图片
  This study evaluated three UVC wavelengths (222, 254, and 282 nm) to degrade patulin introduced into apple juice or apple cider. The average UV fluences of 19.6, 84.3, 55.0, and 36.6 mJ·cm−2 achieved through exposure to UV lamps at 222-, 254-, and 282-nm wavelengths and the combination of these wavelengths, respectively, resulted in 90% reduction of patulin in apple juice. Therefore, the order of efficiency of the three wavelength lamps was as follows: far UVC (222 nm) > far UVC plus (282 nm) > UVC (254 nm). In terms of color, treatment of apple juice with 222 nm resulted in an increase in the L* (lightness) value but decreases in a* (redness) and b* (yellowness) values, although the changes were insignificantly different from the values for nontreated controls based on a sensory evaluation. The ascorbic acid loss in juice treated at 222 nm to support 90% reduction of patulin was 36.5%, compared with ascorbic acid losses of 45.3 and 36.1% in samples treated at 254 and 282 ...
