Innovation Column: European Wineries Now Have a UVC Option for Wine Barrel Disinfection
By Liz Stevens, writer, UV Solutions In winemaking, wine barrels are used during the aging process. There are stainless steel barrels, concrete barrels and even clay barrels, but the oak barrels used for red wine and Chardonnay probably are the best known. Aging in oak allows some oxygen to reach the wine and the wood imparts distinctive characteristics to the taste; some wine … [Read more...] about Innovation Column: European Wineries Now Have a UVC Option for Wine Barrel Disinfection

Measurement of the Output of UV LEDs and Kr-Cl Excimer Lamps with Chemical Actinometer
By Lianfeng Zhang, Laboratory of Ecology and Environmental Protection, Research Institute of Tsinghua University When measuring the output of UV LEDs in a photoelectric radiometer, the probe matched to the specific UV LED wavelength is required. The measurement result of the radiometer is the irradiance of the irradiated point. An understanding of the radiation model … [Read more...] about Measurement of the Output of UV LEDs and Kr-Cl Excimer Lamps with Chemical Actinometer
Germicidal UV Air Treatment: So, What Are We Waiting For?
By Troy Cowan, facilitator, troyc@visionbasedconsulting.us IUVA Healthcare/UV Working Group As we continue to make the case for wider application of germicidal UV (GUV) to reduce the risk of potentially infectious pathogen exposures, we keep asking two questions: What are we waiting for?, and What needs to be done? This is an attempt to answer those questions and provide … [Read more...] about Germicidal UV Air Treatment: So, What Are We Waiting For?
