  • Robust Antibacterial Activity of Tungsten Oxide (WO3-x) Nanodots. [Journal Article]
    Chem Res Toxicol 2019; 32(7):1357-1366Duan G, Chen L, … Zhou R
  • Antibacterial agents are an important tool in the prevention of bacterial infections. Inorganic materials are attractive due to their high stability under a variety of conditions compared to organic antibacterial agents. Herein tungsten oxide nanodots (WO3-x), synthesized by a simple one-pot synthetic approach, were found to exhibit strong antibacterial capabilities. The analyses with colony-form…
  • Reduced titania nanosheets as an effective visible-light germicide. [Journal Article]
    Nanotechnology 2019; 30(40):405602Zhen D, Liu Y, … Cai Q
  • Two-dimensional reduced titania nanosheets (RTNs), synthesized by a solvothermal method, reveal significant visible light-activated germicidal activity. XRD, XPS, EPR, TEM and Raman show successful reduction of anatase TiO2, resulting in Ti3+ formation as well as an increase in the concentration of {001} facets. The RTNs possess a bandgap energy of approximately 2.86 eV, and demonstrate strong ab…
  • The involvement of superoxide radicals in medium pressure UV derived inactivation. [Journal Article]
    Water Res 2019; 161:119-125Gerchman Y, Cohen-Yaniv V, … Mamane H
  • Today, two types of lamp systems dominate the UV disinfection industry: low-pressure (LP) UV lamps and medium-pressure (MP) polychromatic lamps. Both lamp types have their advantages and disadvantages in microorganism inactivation, with LP lamps being cheaper, having longer life, and working at lower temperature, hence reducing fouling, and MP lamps showing better inactivation per germicidal dose…
  • Treatment as prevention and other interventions to reduce transmission of multidrug-resistant tuberculosis. [Journal Article]
    Int J Tuberc Lung Dis 2019; 23(4):396-404Nathavitharana RR, Lederer P, … Nardell E
  • Drug-resistant tuberculosis (DR-TB) represents a major programmatic challenge at the national and global levels. Only ∼30% of patients with multidrug-resistant TB (MDR-TB) were diagnosed, and ∼25% were initiated on treatment for MDR-TB in 2016. Increasing evidence now points towards primary transmission of DR-TB, rather than inadequate treatment, as the main driver of the DR-TB epidemic. The corn…
  • Thinking Outside the Treatment Plant: UV for Water Distribution System Disinfection. [Journal Article]
    Acc Chem Res 2019; 52(5):1226-1233Linden KG, Hull N, Speight V
  • This work critically evaluates the current paradigm of water distribution system management and juxtaposes that with the potential benefits of employing UV irradiation, which we hope will catalyze a judicial re-evaluation of the current practices in water distribution system management and spur critical research and a new way of thinking about secondary disinfection across the extent of distribut…
