Inventors: RODRIGUEZ; Yan et al.AbstractA luminaire includes a luminaire control circuit and a disinfection light source to emit a disinfection light in an ultraviolet (UV) band for disinfecting a vicinity of a physical space of a target pathogen that is exposed to the disinfection light. The UV band is 200 nanometers (nm) to 230 nm wavelength. The luminaire receives a control signal based on at least the…

Hang Yu et. al. research article in Frontiers In Environmental Science regarding the use of titanium dioxide nanotube ultraviolet photocatalysis to degrade antibiotic resistance gees in wastewater sludge.Full text available at: https://www.frontiersin.org/journals/environmental-science/articles/10.3389/fenvs.2025.1590101/fullExcerpts: Antibiotic resistance genes (ARGs) in sludge propagate via horizontal gene transfer (HGT), necessitating advanced mitigation strategies. This study demonstrates TiO2 nanotube UV photocatalysis effectively…

Article at ekathimerini.com about Greece’s Elpis Hospital staff reporting burns proven to be caused by leaving overhead ultraviolet light on for eleven hours during multiple room medical procedures.Twelve doctors and nurses sustained burns while carrying out surgeries at the Greek capital’s Elpis Hospital, their union has said, decrying serious safety lapses at the state-run facility. The…

Inventors:Doyle; Christopher S. et al.AbstractA device and method for disinfecting a surface. The device including a frame; a power source connected to the frame; an ultraviolet light emitting array of light emitting diodes connected to the frame and electrically connected to the power source; and a beam forming reflector connected to the light emitting array to reflect the ultraviolet light to…

Hamed Sobhani et. al. literature review of inactivatino rate constatns for common microorganisms being irradiated with ultraviolet light disinfection technologies.Full article available at: https://www.tandfonline.com/doi/abs/10.1080/23744731.2025.2487390Excerpts:AbstractThe UV inactivation rate constant (k-value) is a critical parameter for designing germicidal UV (GUV) systems. However, significant variability in reported k-values in the literature creates uncertainty. We conducted a comprehensive literature review…

The promise of UV-based air disinfection is no longer confined to labs or literature. Over the past decade, studies have moved steadily toward real-world implementation, yet the pace of change remains uneven. From tuberculosis wards in Siberia to crowded classrooms in Bangladesh, researchers are now pushing for data that reflects everyday use, not just technical…
