Don't Miss Phosphorus Week in November
STEPS will host the Phosphorus Forum November 1-2 and the Sustainable Phosphorus Summit November 3-4
The Science and Technologies for Phosphorus Sustainability (STEPS) Center is a convergence research community of diverse and leading scientists that addresses the complex challenges in phosphorus sustainability by integrating disciplinary contributions across the physical, life, social, and economic sciences. The STEPS vision is to facilitate a 25% reduction in human dependence on mined phosphates and a 25% reduction in losses of point and non-point sources of phosphorus to soils and water resources within 25 years, leading to enhanced resilience of food systems and reduced environmental damage.
Lucas Crane, Masters Student - Lucas is a current M.S. student and future Ph.D. student in Environmental Engineering at Arizona State University working under Dr. Treavor H. Boyer, Professor of Environmental Engineering. His primary research interests are in physicochemical characterization and treatment of water and wastewater, including waste-to-benefit reuse of human urine, implementation of urine collection systems, and application of sensing technologies in premise plumbing systems. In his undergraduate research, he designed a novel biocementation process using human urine and calcium-rich zeolites to reduce the costs of reagents and minimize the environmental impact of enzyme-induced carbonate precipitation; this work was recently published in the Journal of Environmental Chemical Engineering. In his master's research, he is investigating the permeation of urea from human urine through reverse osmosis and nanofiltration membranes. In STEPS, he will be continuing his study of urine by investigating the recovery of phosphate from human urine via chemical precipitation and electrochemistry and modeling flows of phosphorus in wastewater distribution systems.Read More
REU Showcase Live Presentations
REU Scholars and BAE researchers gathered in the Teaching & Visualization Lab to give presentations on our panoramic screen. Guests asked questions and were able to provide real time feedback through our QR code enabled digital link. Our presenters prepared informative works of art that surrounded our guests and provided striking visuals for those watching through our Zoom link.
Review of Fate, Exposure, and Effects of Sunscreens in Aquatic Environments and Implications for Sunscreen Usage and Human Health.
STEPS Co-Deputy Director Paul Westerhoff and The National Academies invites you to register for this public release webinar on August 9, 2022 of a new report: "Review of Fate, Exposure, and Effects of Sunscreens in Aquatic Environments and Implications for Sunscreen Usage and Human Health". The report calls on the U.S. EPA to conduct an ecological risk assessment of UV filters to characterize possible risks to aquatic ecosystems and the species that live in them. The report contains information useful for such an assessment. It also describes the role of sunscreens in preventing skin cancer and what is known about how human health could be affected by potential changes in usage. The committee chairs will share key takeaways and respond to questions.
STEPS REU Showcase
The STEPS REU Showcase took place in the Plant Sciences Building on NCSU's Centennial Campus. Scholars, mentors, PIs, staff, and family viewed the students printed posters in Seminar Room 1322. Guests interacted with scholars on a one-to-one level and were able to ask questions. Our presenters included members of the P4 group.
