From candy apples to N95s: Lincoln agri-food innovation conference shows off new sanitization technology
November 15, 2022 -- When Paul Moyer started making candy apples on his family farm in Lincoln 20 years ago, few may have thought he would be at the forefront of a food safety tech innovation. But now, Clean Works, which Moyer jointly owns, has created a technique which can sterilize food, reducing pathogens, improving shelf life, reducing food waste and protecting the environment. | Could UV Light Reduce the Spread of Covid-19 in Indoor Spaces?
September 30, 2022 -- The empty room was sealed. The scientists started the clock. For nearly two hours, they pumped the roughly four-by-three-meter chamber full of aerosols carrying a nasty pathogen. It was a pared-down replica of the kind of situation that many of us have tried diligently to avoid for the last couple of years. | Unique collaboration produces LM-92 UV LED testing standard
July 26, 2022 -- As reported in April by LEDs' Carrie Meadows, the first standard from the Illuminating Engineering Society and International Ultraviolet Association partnership has been released. LM-92-22 establishes test methods for UV LEDs with peak wavelengths of 200 to 400 nm. This standard will increase the accuracy and consistency of UV LED measurements, ultimately improving germicidal UV (GUV) light sources. |
Seeking COVID’s Kryptonite
June 19, 2022
June 10, 2022 -- To disinfect a surface, you can illuminate it with a blast of ultraviolet (UV) light, which is bluer than the human eye can see. But to specifically inactivate SARS-CoV-2, the virus that causes COVID-19, which wavelengths are best? And how much radiation is enough?

On February 4th, 2021, the China Association of Machinery Industry for Environmental Protection officially released the Chinese standard for “Ultraviolet (UV)-based advanced oxidation systems for urban water supplies (T/CAMIE 01-2021)”. This is the first national standard for UV-based advanced oxidation systems in the world.
UVC disinfection technology: Why an industry standard must be setJuly 2, 2021
Following the surge in demand for ultraviolet (UV) disinfection equipment during the pandemic, the International Ultraviolet Association discusses the rise of commercial UVC products and the need to establish clear industry standards.
Reducing egg loss in shrimp hatcheries
June 17, 2021
Eggs from infected shrimp broodstock have been shown to produce healthy post-larvae if properly disinfected, prompting a major hatchery to change its protocols and a huge spike in juvenile survival rates.
How a Mexico City scientist turned into a clean water activist for Xochimilco
June 17, 2021
It’s an overcast day in the heart of San Gregorio, one of 14 towns that make up the Xochimilco borough in southern Mexico City, and a small canal that ends in a cement landing is surrounded by piles of manure waiting to be used in the cultivation of the area’s vegetable farms.
Applying UV Light to Common Disinfectants May Reduce Toxicity, Finds Study
May 3, 2021
The simple application of UVC light—the type of ultraviolet light that's most effective at killing germs—on common disinfectants can make it safer for humans as well as the environment, finds a study. Disinfectants are used to protect against a wide range of viruses and bacteria, including coronavirus.
California City Embraces UV-C Technology for HVAC Systems
April 26, 2021
Ultraviolet light (UV-C) disinfection has emerged as a popular option for facility managers to combat the spread of COVID-19 over the last 14 months.
The city government of Santa Clarita, California, has fully embraced using UV-C to minimize the spread of COVID. The technology is now included in the city-owned buildings’ HVAC systems, either through retrofitting existing systems or when installing new systems.

Compatibility of Aircraft Interior Surfaces with 222 nm Far-UV Light Exposure
March 9, 2021
Evaluation finds mostly superficial effects. To ensure safe air travel, there is a strong interest in using 222 nm Far-UV light to disinfect aircraft interior surfaces. However, the impact of 222 nm Far-UV light exposure on the mechanical properties of aircraft interior materials, as well as their color and appearance, has not been previously evaluated. This is because airplane interior materials are not normally exposed to wavelengths of light that are shorter than 280 nm.
