1/15/2014 — GEHE Students Graduate
Congratulations to the 2013 Master's students in the Global and Ecological Health Engineering Certificate Program, who have completed their reports and graduated. Kathleen Roberts worked on the growing water scarcity problems in Jaipur, Rajasthan, India. Eric Spooner and Lisa VanBladeren worked on designing and testing a field-based water quality kit and a solar water distillation system. Be sure to check out their final reports on the Teaching page.
11/18/2013 — Our new ES&T paper is among the most read article in November, 2013.
Our new publication "The effects of material morphology on the acute bacterial cytotoxicity of nano-TiO2" (Tong et al., ES&T, DOI: 10.1021/es403079h) is among the top 20 most read articles of ES&T in November, 2013 (based on ES&T database on Nov. 18th). This study revises the simple predictive relationship between the photoactivity and the phototoxicity of nano-TiO2, and suggests that the evaluation of nano-TiO2 phototoxicity encompasses a three-pronged approach, involving the intrinsic photoactivity, aggregation of nano-TiO2, and the nano-TiO2/bacteria surface interactions.
11/3/2013 — Read our new publications!
Our new publications: "The effects of material morphology on the acute bacterial cytotoxicity of nano-TiO2" (Tong et al., ES&T); "Quantifying accessible sites and reactivity on titania-silica (photo)catalysts: Refining TOF calculations” (Eaton, et al., Journal of Catalysis); and “Common freshwater bacteria vary in their responses to short-term exposure to nano-TiO2 in natural surface waters”, (Binh et al., Environmental Chemistry and Toxicology) are online.
11/3/2013 — Tong presentation at the second SNO conference in Santa Barbara, CA
