A few years back, Johnny Eppich at GreenhouseGrower.com reports, the University of Florida grew strawberries under an ultraviolet light system to help combat disease. Natalia Peres, a Plant Pathologist and lead in the study, has since published a paper that showed the system helps control powdery mildew.Now, two fellow researchers have used that same UVC applicator to…

Via newswise.com the Office of Science of the United States Department of Energy relates Chemists create catalysts for use in industry and other applications. One of the methods to create these catalysts is by using light to break down organometallic compounds—substances that include both metals and carbon. These types of compounds are called photocatalysts. Scientists call the…

See t.ly/ACDs — This article presents a review of the main aspects regarding the current rules of classification societies, standards, and practice regarding the design and construction of ventilation and air conditioning systems for different compartments in different types of ships. In the context of the COVID-19 pandemic, this paper also presents the usual practice…

See t.ly/psUV — Peach fruit is susceptible to softening and senescence during storage. In this work, we investigate the changes in genes related to the process of softening and senescence in peach fruit treated with 4 kJ/m2 UV-C irradiation based on transcriptome sequencing. A total of 3,416 unigenes with more than 2-fold difference in expression…

Last year, Senior Editor Eliza Strickland at IEEE Spectrum recalls, germicidal ultraviolet light found a place in the arsenal of weapons used to fight the coronavirus, with upper-air fixtures placed near hospital-room ceilings and sterilization boxes used to clean personal protective equipment. But a broader rollout was prevented by the dangers posed by UV-C light, which damages…

See t.ly/Ya6O — This study aimed to evaluate the inhalation resistance(IR) and fiber structure of disposable masks when exposed to repeated heating and ultraviolet(UV) sterilization. The experiments consisted of a lab-scale and a field test. For the lab-scale test, KF94 and N95 masks were selected and a trial was composed of three repetitions of an…

See t.ly/3gRz — The ultraviolet (UV)-based advanced oxidation process (AOP) is a powerful technology for removing pathogenic microorganisms and contaminants of emerging concern (CECs) from water. AOP in potable water reuse has been predominantly based on traditional low-pressure mercury (LP-Hg) lamps at 254 nm wavelength, supplemented by hydrogen peroxide addition. In this review, we assessed the…
