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?

Hansen: Shining the light on collaboration

November 3, 2021

Tata Steel BSL installs first UV oxidation plant to treat wastewater

August 9, 2021

Tata Steel BSL, the largest manufacturer of auto-grade steel in India, has successfully installed the industry's first ultraviolet oxidation unit at its facility in Dhenkanal district, Odisha to treat cyanide in coke oven wastewater.

Kentucky awards $11.8M grant for UV wastewater retrofits

August 5, 2021

On August 3, Kentucky officials awarded $11.8 million to the Lexington-Fayette Urban County Government (LFUCG), the second recipient of funding from the Better Kentucky Plan’s $250 million Cleaner Water Program.

Dandaragan farm spring water worth bottling

As anyone who has farmed would know, the most innovative ideas happen when you are behind the wheel of the farm workhorse - the trusty tractor.

Pulsed UV light to decontaminate eggs

July 19, 2021

Researchers at Penn State College of Agricultural Sciences in the US have discovered that pulsed ultraviolet (UV) light can be an effective means of killing pathogens found on eggshells. This is a valuable finding for the poultry industry.

China AOP Standard: Ultraviolet (UV)-based advanced oxidation systems for urban water supplies

July 8, 2021

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 set

July 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.

Earth Day 2021: A Closer Look At New York City’s Water Supply

April 22, 2021

GRAHAMSVILLE, N.Y. (CBSNewYork) – The source of New York City tap water is roughly two hours north of the Big Apple and beyond, nestled in the bucolic countryside of the Catskill mountains, sits the Catskill and Delaware Watersheds, the origin of the “the best water in the world.”

The power of architecture to address public health and environmental crises

April 5, 2021

Two studies by Dorit Aviv, assistant professor of architecture and director of the Thermal Architecture Lab in the Stuart Weitzman School of Design, show how architecture can help create interior spaces that are both COVID-safe and energy efficient.

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.
