Acidic sulfur emissions from power plants have been rapidly declining over the past decade, and the neutralizing base – ammonia – is emitted from a different source, and has not declined. This has led many atmospheric scientists to assume that the ambient sulfate particles we all breathe are becoming less acidic and therefore less toxic. But a new study shows this intuitive expectation hasn’t happened, at least not in the Southeast United States, where the remaining sulfate particles appear to be as acidic as ever.
Professor Terry Sturm and former Ph.D. student Seung Ho Hong have received a top research award for hydraulic engineering from the American Society of Civil Engineers. Sturm and Hong won for a study on predicting the amount of erosion, or scour, around bridge supports during floods.
A chunk of concrete dropped off a wall into traffic Jan. 30 in the Yerba Buena Island tunnel that’s part of the San Francisco-Oakland Bay Bridge. Now the California Department of Transportation is investigating whether there’s more corrosion in the tunnel that could lead to other problems.
Two assistant professors in the School of Civil and Environmental Engineering have won one of the nation’s premiere grants and the National Science Foundation’s most prestigious award for junior faculty, the Early Career Development award. Chloe Arson and Phanish Suryanarayana learned of their selection in early January for what are known simply as CAREER awards. The grants recognize the top educators and researchers in the country, those who “exemplify the role of teacher-scholars through outstanding research, excellent education and the integration of education and research,” according to the NSF.
There’s now so much space dedicated to storing cars in Los Angeles, it takes up 14 percent of the county’s incorporated area. That amounts to almost one residential parking spot for every registered car in the county and three spots per car overall. Those findings come from a just-published study by the School of Civil and Environmental Engineering’s Ram Pendyala and colleagues at Arizona State University.
Kimberly Kurtis surveys innovations in cement-based materials and efforts to improve the sustainability of concrete in a new article published in a December 2015 special issue of MRS Bulletin. The issue celebrates 40 years of the journal from the Materials Research Society. Editors invited Kurtis’ to explore recent developments in the design of concrete as part of the issue’s focus on the interplay between materials and engineering and how that relationship is driving innovations in materials.
The School of Civil and Environmental Engineering honored its best teachers, researchers and staff Nov. 23 at the School’s annual awards reception. The accolades recognize the best classroom teaching, the top research efforts by faculty and students, and service excellence from School staff.
The Design-Build Institute of America has named Baabak Ashuri one of its top leaders for 2015 for his work teaching about design-build processes. Ashuri, an associate professor in the School of Civil and Environmental Engineering, received a Distinguished Design-Build Leadership Award from the group Nov. 18.
